What´s it all about..

2011-10-16T17:13:00.003+02:00

Rules in Pro Twin Bike mandates that the rider starts the bike using the onboard system, I kick start which gives the advantage of carrying less Amps and less weight. The disadvantage is not being able to set mech. comp. much higher than 13,5. A few years back the pushbutton racers got a change to the rules allowing remote batterys which kind of took a bite out my advantage, but I´m not whining about it. But what the hell I wouldn´t mind a class with no wheelie bars and Kick start only...... It´s kind of complicated to explain, but I still believe I have some advantage, running much less complicated electrical and the fact that I´m challenged to be properly tuned at all times. I do have a remote starter when I´m up on a lift or stands, and it has saved me a lot of grief when lost in tuning and little time to T/S.

Good weekend

2011-10-02T01:31:00.003+02:00

Ran a 10.16 at Tierp Arena, personal best and I got som good data, totally different baseline after the headwork and I´m down on mainjest to numbers at the lowest end of my chart. Everybody else was trying to get richer on fuel as the air was 100%, and I couldnt believe that my A/F log recorded I was already fat, so after going against the data and loosing topspeed I ended up with the smallest Main Jets I had...and I´m back, and really satisfied. The winner Mikael Bagge/Warrior Racing Yamaha Turbo outperformed even himself and ran a super final aginst Keneth Holmberg/Swecomposite

Magic @ Tierp Arena

2011-09-29T23:17:00.000+02:00

Last week of September in Sweden can be compared to places like Anchorage, of which i have limited experience, but i general here in Europe drag racing is very dependent of weather, and right now we got warm blue sky and dry, for a dragracer this is Tropical, add a robust forecast for continuing warm and dry and the ambitions rise, cause this may be what we have to remember for the reminder of 2011.I`m thru tech Inspection and seven Pro Twin Bikes are in,

A-Check

2011-09-27T15:32:00.001+02:00

Tension is building up for the last and final race at Tierp Arena, no less than 33 TopDoorslammer (Outlaw) are registered and the bandnames for the final party in the GoldenBarn are actually known....so as of tonight i´ll start race preparations with leakdown and removal of the fr. head to correct an oil leak which came as a result of having to do a makeshift fix earlier when the return line from the fr. exhasut tin was soldered shut. I quess the Quality Inspection Engineer was of duty at the tin manufacturing plant............. but what the hell it´s intersting to see what the chamber looks like after the last w.o.t. runs.

Allright test

2011-09-19T21:01:00.000+02:00

Kjula Dragway, is friendly efficient and relaxed. Did a good 1.57 60 fot launch which felt perfect and like you want to store it for future use, thru the quartermile trap @10,2732 e.t. and 206,66 km/h, somewhat lacking 5 km/h top speed, but next week is preparations for "Night of Fire" so I will take leakdown and check timing.
This week I´m, Dad, work and getting my house in order.

Sunday

2011-09-18T07:55:00.001+02:00

Yesterday was break in and adjustments, not so cool was when I realized right before my first run tha tire press was adjusted for street, no gauage so I just released on a hunch ended up too soft.
Took of wheelieing 10.90/203km/h. Today it feels like we might be ready for som W.O.T.

Racing this weekend

2011-09-15T22:27:00.001+02:00

Kjula Dragway this weekend, is next to last opportunity this year, after that Tierp Arena and "Night of Fire" last weekend in September. I wonder what the odds are for a dry track by then but what the hell, the party barn holds four hundred. I will test this weekend and try to break it in and tune, so I really don´t expect PB´s. I have shaved of more than 20 punds of myself, so sure if all is as it used to be it should make a difference.

Warmed up , flushed & leak checked.

2011-09-10T11:55:00.001+02:00

Ran a couple of quarts Oil thru on the warm up, topped up and took it for a spin. Hit third gear outside the retirement home out of pure love, one never knows, it could make somebodys day....Engine is completely dry, pipes are dry and it felt like it delivered. next weekend is test at Kjula.

Ready for startup

2011-09-04T20:18:00.002+02:00

6 days and 6 Nights later I´m finished with the overhaul after the Exhaust valve dropped into the front cylinder. The crank and rods are refurbished and the heads are as Zero set as they can be.Seats, Guides, new tins and spring washers.Most challenging has been to produce absolute round Seat recesses as the weld repair did pick up carbon from the iron, and hard it gets.In the Sunnen the borehead has two cutters and the solution was to run on very low RPM with only one. Then when ran in to the same problem cutting the seats using a typical set up where the cut extend outside the seat to match the surface to make the smooth transition, worked around it by becoming dentists using a 700000RPM grinder to remove hard material very precisely. all well the bike is completely ready for start and I´m celebrating. Nothing would have been possible without the help from Cala Steimar at Calas High Performance. Everything done or parts used was checked and double checked, one of the new intake valves was found to have variation to the stem dia, so it was honed straight by using a diamond setup, and one of the new tins had to be opened up after found having the scavenge tube soldered complety shut,

Honing hard chromed stem

The Front Head after the failure

The same head after restoration

I´m on it, barely....

2011-08-12T12:41:00.002+02:00

Due to sad but unavoidable circumstances I have been off track for a while. Eventually I did collect myself and did a reenergizing 3 days in Cala`s shop. Finished the surfaces on the heads successflully, designed new valve guides with some minor changes and adapted to the original style tins, departed from the idea of having the guides holding the tins, but improved the guide for locating the tin and bottom spring washer. Completely rebuilt the crank, new shafts all three, Remains to install guides, machine seat recesses, install seats and do a slight hone in the pair of cylinders with Ross pistons this time. Good news is that the Racestar organization invites to an event last weekend in September on the the new track Tierp. I will do everything possible to be there with a serious intent to nail the single digit.

Logistics

2011-07-24T16:20:00.004+02:00

Collected the parts needed to zeroset the heads, new tins etc. The Crank needs a check and I needed to adjust (change) the drive shaft in order to correct a spline length issue. C´s shop is very full and transportation of disassembled engines is not necessarily easy, so i made a prototype cabinet on rollers with a detachable undercarriage. Easier said then done as always, some of the oak blocks had to get added functionality like the rear engine mount got hinges to allow the cases to rotate down in the cutout. The basic cabinet was so flimsy that I had to weld some square tubing to the undercarriage otherwize it would not have been possible to detach without it falling apart. Took pictures before it was finished and it actually turned out allright.

We have also ordered the cases and crank etc. for the new engine, so the cabinet will actually stay at Cala´s shop while the components for the new engine gets completed.

Waiting and a Movie

2011-07-14T22:51:00.000+02:00

Ordered Tins a couple of weeks ago and I´m patiently waiting for the package. Meanwhile you can watch a serious movie in which I´m racing against a legendary ironhead "Sprutster" and I really think he is running on Jack D. and he is good, , this is the run last year where i realized my kickstand came out so I held on to the rotation and landed nice and soft...

Preparations

2011-07-03T13:59:00.004+02:00

Received the Heads back from UCC where Ronna in master fashion prepared and TIG welded the material required to fill the dimples, he also cleaned out the mysterious fillings between the seats on both heads (hard soldered) and filled that as well. After some reasoning and analysis toghether with experience it turned out that the FHP Castings are weldable, hence I turned away from trying powder welding and it came out very nicely. So next step was heading to the holy grail of restorations and Cala´s High Performance, and we had a great day and a half (and a great lunch too), finishing fixtures which would accept both NOS heads with Tins installed as well as these heads which caused some adjustments to the height and location in the Sunnen machine having an added straight exhaust tube. The fixture required for the lathe was also cleaned up. Cala`s Machining capability and absolute requirements for preregusites in the set ups, fixturing and dimensional control is what´s needed restoring these one offs, New tins are on the way and we are looking at installing as original with the guide holding the tin, but one step at a time and now it´s machining, Guides, Seats, Valves ......(the bottom picture is the ´rear head from "Mother", the other pic´s are a pair of original).

Update

2011-06-24T17:03:00.000+02:00

Heads are in good hands in order to get material added to dimpled surfaces.

Planning is underrated..

2011-06-20T09:17:00.001+02:00

Allright I got some danged up surfaces in my front head, no cracks so..
Decided to remove both heads and strip completely, seats and all.
I have some added material between the seats most likely welded in way back chipped just slightly. If everything turns out right with vacations I might have both heads in the powder welding next week already, so I´m busy stripping. And, yes..the entire engine will be stripped and checked, the head work will be restoration not just repair.

Challenged

2011-06-19T20:17:00.000+02:00

Klonk!

2011-06-19T16:36:00.001+02:00

Blacksmith Nat´s was fun as always,. more altereds, Norwegian Classic dragbikes, Nitro Ironhead Sporters, double engine nitro Java etc etc, I believe i did six passes and I was chasing some lost topspeed, found it and started to manage my launches, and on the final pass Saturday, hitting third gear I lost thrust and it sounded like I would imagine a rod coming out of the Engine Block, came to a halt, engine still running turned it of . no hole, no pool of oil....In the pit after being towed I started to turn the engine with the kick start slowly and it turned to a stop, so started to remove the front cylinder plug and it did not feel right, so, something is doing something it´s not supposed to in my front cylinder. back home and unloaded , I will take a closer look tommorrow.

Good times

2011-06-16T15:29:00.002+02:00

The European and NDRS Championship racing was sweet, Tierp Arena is beyond expectation and coming in to the campground and greeted by one of the Builder/Owners, is stuff that makes myths, boots on the ground.
Fantastic racing and I take Mr. Ashleys (SuperTwin Top Fuel) and Tommy Johnsson J.r.`s (Top Fuel) with me, very professional indeed, good show. I´m participating in Blacksmith Nat´s this weekend, pre-73 stuff and more on Kjula Dragway.

Time to see some real Dragracing

2011-06-10T12:55:00.000+02:00

Finishing up at work, truck is loaded with necessary beverages..., and we are going to Terp arena to watch, smell and hear high class European Championship Drag Racing. 13 Top Fuelers and well over 30 Pro Mods, Pro Stock etc in the new arena, I´m really looking forward to it.

Inspirational

Bad Timing

2011-05-29T22:09:00.000+02:00

Waited out the rain, and it looked real good, just another Jr.Dragbike, myself and not so many cars., When we are about to get goin, the Timing equipment dies...

Loong day

2011-05-29T00:34:00.002+02:00

We had a great event today with an inviation to the test twin bikes on the track, supported by the drivers association STSBA (Super Twin Street Bike Association) free hot dogs included, and some twenty newcomers to the sport tried out on the quarter mile and we will surely see more of some of them in the future.
My runs wasn´t very exciting, a couple of 10.35 , 10 .36 but at least I finished the day with a 10.2480 and
212.85 TopSpeed, but in between I did som double wheelies which kind of makes me mad when the track is predictable and it´s just in my head.
It always comes back to yourself, what if this... and what if that..., tommorrow I will be focused.

At the track

2011-05-27T23:42:00.001+02:00

Arrived to the track, watching the weather. Noticed some hits from Philadelphia, got to be "Columbo" our latest export to the U.S., not homesick are ya,....didn´t think so,..but it´s sure nice to be at the track.

Kjula Dragway 28- 29 May

2011-05-23T22:27:00.000+02:00

Timeslip racing coming up this weekend, Kjula Dragway relaxed and good track.

Cancelled by rain

2011-05-16T18:03:00.004+02:00

Sunday was cancelled when the rain came on and off, but I´m still happy. Good feeling when things work right away.The CORDONA SHIFT KILL SYSTEM works perfect and I was able to focus on the shift light and the light on @1000 before the shift RPM and then strobing when time to shift, I made a diaper with a replaceable absorbing material and just beacuse of that it didn´t leak worth mentioning. I´m still curious when I forgot that I had the shift point @ 5300 v.s. my normal 5700 beacuse I was testing and forgot the low setting, the bike remains in the AATV (Acute Accelerator Transport Vehicle) Next race will be Kjula again for me.

True Heroes

2011-04-28T21:33:00.001+02:00

The True Heroes this winter is the robust crew who took the first step in building Europes first purpose built dragracing facility late last fall. Tierp Arena . Record amounts of snow and a cold winter and they just did not bother. They have proven unrivalled stamina and progress, never before witnessed in any large infrastructure project in this part of the world,....ever.

Tierp Arena

Vintage Drags

2011-04-27T17:28:00.000+02:00

First Test & Tune is now at Kjula Dragway 14-15 May, I´m signed up.
I also noted the upcoming Vintage Drags in Ohio June 25 -26 , wish I could be there, check it out at www.vintagedragbikeracing.com

RPM´s

2011-04-25T12:20:00.000+02:00

Allright, with the help of my lathe i got a totally clean tach signal (WHITE cable from the DYNA) and went on to set up the CORDONA system.
With a threshold RPM at 3000 i will be able to down shift and change gear before and after the burnout without
risking cutting the engine, I´ll start testing with load cell @ 7 kg´s and an interrupt time of 65 mils. Shift Light logic is in the CORDONA and it is somewhat different with the light coming on @ a1000 rpm before and then it starts to strobe with RPM frequence when it´s at the set max RPM. Now, if this is going to work in the not so forgiving real world of 5 1/4 stroke remains to be seen.. I´ll disquise my futile attempts of a clean electric installation mounted on a dampened shelf under the right Tank shell.

Observe, adapt, conquer.........

2011-04-23T13:12:00.003+02:00

Rules changed a couple of years back and today we can run Two Step RPM limiters and shift kill systems.
I haven´t done any of that caus'e I´m really a fan of K.I.S.S. (Keep It Simple Stupid).After some time competitors got some of those things to work it is now proven to be an advantage. So, Two step is down on my list as I don´t run a adjustable slip clutch, I may come back to that later. Shift Kill however gets my attention, basically due to the physics of quicker shifts and less vortex inducing throttle dips.Now.., my middle name is not Tesla even if both my Dad and Brother where professionals, or maybee that´s why and I have failed to get a stable tach. signal to my WEGO 3 log from the Dyna S ignition, and yes, I have tried all the tricks in the book. So I did some research and found one particular shift kill system having a load cell with sufficient quality to survive. But first I have to get the hang of getting the Tach. signal.
Unaware about the unpublished fact that Dyna 4000 has a "dead rev" function I installed it last year. It has a dedicated Tach. out and many other features geared to my current needs, sure... I started the bike with the handheld and it ran just perfect and then tried three kicks before I called tech support, "It will be extremely difficult" was the verdict, so I removed the whole thing, and nothing is compatible with the dyna S not even the Cables...back to the Dyna S as my own rulebook requires kickstart and now I´m really serious about getting a tach signal. Time to build a test rig using the spare Dyna S and after one night i have found out that conncting to the "S" pickup with the white cable out, I can get proper RPM readings to both the WEGO log and the CORDONA shift kill. If I use the Black cable I get spikes and interrupts which confirms my experience with the system on the bike, next test will be to try all the variants of a Tach Adapter, which I have tried before with no success, but now whith the rig and and the knowledge that the signal from the two pickups differ´s I can experiment, and the rig is essential as I don´t have to start the bike two hundred times to test.

Kickstarting

2011-04-16T18:38:00.000+02:00

Roll Out and kickstart

2011-04-16T18:13:00.000+02:00

Untouched except from a replaced kickshaft I rolled out "Mom" today and started up, Sun is shining and we do think the winter it´s over. Made a little Movie for you ...

28th May it is

2011-04-09T00:15:00.005+02:00

This season will be selected events only. and Kjula Dragway 28th May is the first.

Got a minute ?

2011-03-27T18:04:00.000+02:00

If you have a few minutes check this video, it´s...revealing.

Big Twin talent

2011-03-18T22:16:00.000+01:00

Here is a link to a movie where (in my opinion) one of the the best Big Twin drivers and tuner hits a 9,28 on the quarter mile, Conny Karlsson don´t mind racing against me as it seems his best runs are against yours truly, in this race he certainly wipes out the fat guy in the other lane

He doesn´t hesitate trying different combinations and I´ve seen many variants of Dual Mikuni setups and then suddenly a single S&S on a high homemade intake, and it always surprises me how he manages to do it no or short time, good welding, machining, raceworthy installations and attention to detail, respect

Seats in place

2011-03-03T21:27:00.000+01:00

Allright, got the seats where they belong, relieving will be after intake and exhaust ports are set and radiuses in the channels are known, I can introduce spring seats, guides etc, as they are pre req. for the intake and exhaust envelope.

Yeah I´m workin on it

2011-02-11T17:39:00.002+01:00

Retrieved the Jim Miller "Mid Lift" theory papers so I am working on it. Got the intake and exhaust seats on the desk so I have those and the rollers for the rocker arms so that´s what I need to set the geometry. But I´m currently cleaning up the rocker housings and still have the ambition to use as many parts as possible, like the "Tin" covers", So..any decade now..............

Snow and challenges

2011-01-06T22:40:00.001+01:00

Shoveling snow is becoming an every other day deal in Stockholm, and it came like a month earlier than usual, but I even enjoy it, beacuse it´s easy, healthy and instantly rewarding compared to restoring the harddrive after serious crash . Looking at the screen nervously (I didn´t back up my latest work) when the file system gets restored sucks. Anyway this pick is a cooling fin, just to prove progress on the head work, this is the 2nd from bottom on a normal front head but in my case it´s the 3rd as I have added two.

Merry Christmas

2010-12-22T21:19:00.000+01:00

To all my Friends and everybody else.
Special thank´s to Dave at Morris Magneto, Don at Hilborn and Jarmo who keep it toghether for so many.
Now it is up to me to get the details right and the Ironhead Fuel Injected.
We got snow, and lot´s of it, but I keep my runway clean, Santa can land safely here. no problema.

Time travel

2010-11-21T16:08:00.007+01:00

I´m exploring a couple of areas more or less unknown to me, Mechanical fuel injection and the very tideous project of bringing a set of heads to birth. Basically MFI is the only righteous FI option for "Mother" and my approach is to listen very carefully to individuals who has proven it´s functionality with time slips and speed performance, and Hilborn has been very nice and responsive.

The Heads is another story and it´s been going on for years now, right now I have all critical dimensions and patterns set and checked and then checked again, I`m also self educating myself in the CAD world and it´s not my day job so everytime I get back to it, it´s days of finding my way around SEKE´s, cordinates and views. But now I honestly think it´s time to make some shavings. With some help from Karling Racing I got the cubes of Uddeholm "Alumek" in the shop a year ago and the last few days I found some time (loooong hours) to verify height dimensions for the rough machining to get it started. I posted a pic with a original dimension head in a same size cube rendered like glass (yeah I know it´s b.s.) but the Winterbrew tasted well when all dim´s where in.The final product is all about performance and basically 5/8" taller than original heads adressing the limitations such as spring height, short grip for valve guides etc and the capability in todays CAD very quickly reveals the possibility for slightly less valve angles as the valve seat is further down.etc, etc.

Any decade now and it will be done. and if you wonder about the choise of material it´s easier the first time with Alu. and two very heavy chunk´s of a secret steel matrix in the shed.......

Planning for the mods

2010-11-03T14:55:00.002+01:00

Canned the idea of hex holing the cam for the Mechanical Fuel Pump, and if driven by the cam it´s done differently, basically pressfit of a hex 3/8 bolt head. The way I have it now i will add a drive to the Generator pad. for good reasons, pump will be in front of the engine rather than sticki´n out on the right side, and it´s logic when the intakes are on the left side with shorter lines etc, the cam cover will be left untouched.
The drive will be partial Morris Magneto H5 drive gears and flange and additional bearings/plate. Kind of a nice winter project. haven´t decided on the type of pump fitting yet, flange bolted or clamp I´ll decide after I got the drive design set. And sure a magneto would fit nicely but that would be another project when I´m satisfied that the mechanical fuel injection is the way to go.

Things to do

2010-10-16T12:42:00.001+02:00

It´s easy to slow down at this time of year and then you realize in April what should have been done.
I´m off to SoCal next week and target for my spare time spells Hilborn and Jarmo P.
I´ll be smarter after that...
One camshaft is due to be handed over to Nicma and get Hex-holed.
I did the tricky part on installing a side door on the Hauler, now I have to figure ot some clever opening/lock mechanism, typIcal I´ll do it later that never get´s done.
I even managed to order som Amber lenses for the LED strobes on the old EMS hauler, my current blue are basically so illegal and I figure it´s only a matter of time until I get pulled over and it is amazing that you can find anything on the internet and have shipped in five minutes.

Too late for race

2010-09-26T19:20:00.001+02:00

I was hydroplaning into Mexico City on Thursday, so home late Friday and no time for racing.
Too bad, I really need another wide open run before winter.
I´ll post a pic that looks like all the other, this one taken at Mosten by Finn Bojer, I only remember it felt real good.

Fall, too early

2010-09-13T22:35:00.000+02:00

One track is open next weekend but I can´t make it as I´m travelling.
To bad I would really like a full length track before going in to hibernation.
The wicked people in Orsa (Dalarna, region in Sweden full of motorheads) are providing a fully prepped track 25-26 september, could be snow by then but I´ll think about it, nice drive and beatiful country as well. Bike is ready, needs an oil change and a kick shaft, but that would be it.

Mosten rocks

2010-09-06T21:10:00.007+02:00

Mosten is different from other races, good mix of spectators with the great majority bikers who can´t spell trailer.
The response is great and any combination get`s it´s share of fans and some of the bikes raced here would not turn up elsewhere. a very well prepared track and super proffesional crew. I worked hard on my runs and in the final 3 attempts I managed a 6.501/177.05 which was enough for a third place in the field of eight starting in the Harley Drags Class. Rules are simple, anything goes except wheelie bars. I broke my kick shaft early on final day and had to remove the gear and clean up the cover, safety wired shaft secure in the hole and went looking for a crew as I now had to use the remote starter, not good for the image but WTF, no problema Atte and Perry gave me a hand , thankyouverymuch, and a Pro Mod Corvette crew lended their little cart to take the batterys and starter to the line up and the rest is history (or at least a story) I got a price and even some price money. The motor was running stronger then ever and it felt like a screamer, the 177.05 (110.01mph) top speed done twice is much better than any previous on 1/8 this year and maybee, just maybee the geometry correction on the rear exhaust rocker did make a difference.

The truck is back

2010-09-01T13:32:00.003+02:00

Got my hauler back after the transmission repair, and it is a good feeling when it is so obviously done right, on time, at the right price, hat`s of to Norrorts Bil och Van, also I have had very good help from my local shop, Åkes Bil och Motor ÅBM to troubleshoot and much moore. Andreas at ÅBM is running the Engine Overhaul shop and he is also just about to completely finish his ProMod Chevelle, an amazing feat by a guy in his twenties ÅBM Racing.

Race ready

2010-08-29T21:40:00.001+02:00

Serviced both heads over the weekend, major oil leak in the front intake tin was explained as the bottom of the cup was separated (cast alu) , had to restore one original tin for a replacement,the shaft hole was big as a quarter so I welded in a washer with the TIG on 35 amps and it worked out well , no dressing required. I also finshed up a rear exhaust rocker arm with bushings in both ends and spend some time on tooling on order to reassure geometry (mid lift) as I this was an opportunity to correct.
Fixed a problem with the right handlebar as well.
Started to remove heads 10 a.m. Saturday and I´m completely race ready 9 P.M. Sunday and a stranger to the rest of the family...., I´m off to Mosten on Thursday.

Mosten Raceday

2010-08-26T17:04:00.003+02:00

2 thru 5 September is Mosten Raceday/Denmark, finals are on Saturday and Sunday is recovery of what´s left...
If you click on the "You Tube" logo in the Mosten site you will find some evidence of which one is my good neighbour burning rubber out of the bar in his blown -32, 5 window hitting a pole spun around and took the wall down on another bar across..........Bar run
The hauler is in for a Code 1870 transmssion slip deal and I spent quite some time to locate a reputable shop to fix that and they are on it. I´m servicing the bike this weekend, got some things on both the front and rear head, including replacing the rear exhaust rocker arm with one that I prepared with bushings in both ends.

Blacksmith

2010-08-21T18:14:00.001+02:00

10.248/212,77, on my last run and got some mechanical on the return so i´m done.
Previous was 10.293/214.54 so there is some consistancy.
I´ll have a beer, or two.... The "Six Shooter" slingshoot ran a 7,2xx something and this track is 7,50 "breakout" so i guess that was a mishap..........

Fail stage

2010-08-17T22:09:00.003+02:00

A "Fail stage" ruined whatever chances I had. "Fail stage" is when you roll back out of the stage light after it being lit, that happens not necessarily due to being nervous but rather over focused, forgetting about the possibility when it has not happened in the last zillion runs and being overcautious not to deep stage...and with a springer front end and launch RPM getting up, the wheel bounces alot, enough to clear the beam....anyway I lost.
Ran a time slip after the finals and managed a 6.65, better but still..........

It was real nice to see "Columbo" back, normally to busy to attend and used to wheelie down on a Shovel chopper style with some unmanagable homebuilt Injection system, now he turned up with a well built bike to the latest numbers carburated Evo, and took it all the way to the final with a best of 6.124/182.6 but aginst the remaining Dane, Marcus who ran a best of 5,613/203.9 most anybody on this planet is runner up. 15 year Old Marcus will end up with the championship this year.

Next for me is "Blacksmith" Pre-73 this weekend, overpowered slingshots and some real crazy wonderful people, insane Norwegians and a good track.

1/8

2010-08-15T00:31:00.007+02:00

Embarrasing,

No excuses, bad driving and a few mishaps.

12th qualifier in a 16 stage, and 6.67/173.13 is nothing to brag about, missed out on the last two attemps, first I broke my rear brake pedal in the burnout, (long story), 2nd time a rocker nut leak developed with a steady stream of high press oil. Will face the scary Yamaha warrior Michael B tommorow, turbo, coolers,electronics and what have you, and he knows how that shit works.......but on the other hand he´s still having his birthday party and i´m going for my beauty sleep, it ain´t over until the race is done.
The good part of today is that Mr. Swecomposite most likely found the ghost on his V-Rod Turbo setup and made a very decent 6,4732/190,81, first time he had a clean run, and tons of work behind, but that´s what it´s all about, perceverance.
My first belt since -84 had to be replaced (stone punched a hole) and my nut´s are tight...tommorow.

"Honeydoos"

2010-08-10T20:29:00.000+02:00

If I finish up the the kitchen workbench, elecric outlets, benchlights, and trim I been promised a
Jack just like the one seen in the fearless Norwegians toolbox, and I have a race this weekend.
I´ll better get started..

Vintage racing

2010-08-03T23:15:00.000+02:00

OK! so that´s a track prepped by xperts.

Bike ran well and 10.30xx/206 km/h on the first is allright for me, next was the longest wheelie I ever held on to, I just would not let go off the throttle , 10.4 something, my kickstand came out and i had a hunch so I made damn sure not to lean over to left. I have to make a "lock" feature for that, reason was the return spring dislocated and actually acted to pull the stand.....it can be seen on the pic, click on it.
Also check out the pics on this link http://www.mek.nu/bilder/010728_btb/index.html

Getting ready for "back to basic"

2010-07-25T22:28:00.002+02:00

Bike is loaded in my trusty hauler, a -97 ex. emergency vehicle 4 ton Chevy retired Ambulans.
Don´t think anyone died in it, but maybee a few births.
3500K 6,5 TD is reliable and I try to take good care of her checking fluid levels and such.
I kept part of the oxygen system for later, who knows how long it will take before i either get there or quit (die that is).
Interesting to try a track preperad for the heavy hitters, I will give it my best.
Rear light has to be on the bike as we may run late on saturday.
Noticed some hits on this blog from North Texas, greetings, I have done some work in Wichita Falls when I worked out of Claremore OK, North Texas has the big sky.
As a matter of fact I did "Hotter Than Hell 100" back in -97, and what a sick idea that is, 100 mile bicycle run in August and no less than 105 F, damn....

Health

2010-07-18T23:53:00.003+02:00

All well, "Mother" is up, started, crissssssspy.

Took time to check up the on the neglected "Gudrun" 96 incher, leak down check on front was 6% allright, rear was another story, sooo sick 98% exh. leak no wonder she was limp and coffing.

Put together last time 2001 and hasn´t dropped a bolt since, time for some T.L.C.
I wonder where this is going to end.........poor thing is rusting.
Rumours says another guy is putting a Leineweber 5 in his street job, hmm got one of those
somewhere.......need more comp....and springs....and........
.

Lesson

2010-07-14T18:51:00.003+02:00

5 1/4 stroke, rpm´s @s 6,500 on 15 runs over a couple of days.
Day 3 and during the burnout the rear exhaust valve decides it is time to retire.
Steel pieces of which the largest is about 3mm leaves the edge of the valve

and are in a hurry to get out. The valve doesn´t quite close when the pieces are leaving so the pushrod leaves the ball on the rocker arm and now hits the ball with the edge of the pushrod cup. and with very limited travel to coil bind that is exactly what happens, and something has to give...this time it is the rocker arm at the
spring end.

I will miss this rocker arm, it has done a good job and had bushings in both ends.

I have a spare one already prepared which mr Baisley did the roller on, not bushed on the spring end, but it should not be a problem these days after i learned to adjust pushrods with generous clearance.
To little and the knuck will starv for oil on the shaft at the spring end when clearance is eaten up by the hot valve, and with hard springs and steel to steel it seizes on shaft.

The valve is a 5/16 stem 1,800" but somewhat taken down on the dia.
I used a S&S S B2 head exh.valve to start with and reduced thickness on the disc and the dia , cut the groove and then the stem to the right length.

New S&S valve on the left and the reduced new valve is right.

Ok i got a valve and a rocker arm

I have not decided if I should go into a full head rebuild with guide replacements and the rest, or just put it togheter which should be ok and then do the zerosetting coming winter, there is still three races left this season.

Will exhibit in the "Back to Basic" races at Mantorp last week of July, after that we have championship races first weekend of August in Lindesberg, and after that it´s Mosten Raceday/Denmark in September, Mosten is end of season, great music and gigantual party.

Out

2010-07-11T13:33:00.000+02:00

Sunday and one or two runs available before eliminations,
after the burnout i lost fire on the rear and my carbs started to come off, familiar
indication of valvetrain problem, and it was the rear exh, rocker arm.
For those who follow me this is something I had problems with before.
It looks a little different this time and it may be easier...but not today, my spare is back home.
So I´m in to the fine art of eating hamburgers in a crosswind and watching my buddies.
Home alone next week so I should be able to focus on fixing it.
This event has been the best excersize I ever been to.

Allright

2010-07-10T22:23:00.001+02:00

10,2078/211.42

I got 10 time slips on my table, this is the kind of event I need.
10,2842 followed by the 10,2078 and again it is the strange feeling of calm when it´s
going well, "what´s for dinner thoughts" between full throttle shifts.....
Air is good, no tach signal to the logg but with the number of runs we
have i´m trying different setups, so I´m upp on mains right now and
we will have more runs tomorow before the eliminations.
If anyone knows how to get a stable tach signal from a dyna S, let me know, I have tried
the standard shit that comes with the unit, the logg is a Wego 3.

it workzzzzz

2010-07-09T22:16:00.000+02:00

Retarded 2 to 3 degrees (blooody strobelamps) and it´s breathing freely again.
Huge wheelie but revs way way better, will not be a time to write about but
I´m looking forward to tomorrow.
The slip from the previus run was 10,3077 so it´s improving.
The timing excersize shitted the plugs so I had to kick 45 times to get goin, should have
cleaned it out by driving to the line up, anyway the T/F teams nesting close to the line up are all smiles and sympatetic towards this sorry fat kickbag....

All bike weekend

2010-07-09T16:52:00.001+02:00

On a short notice I entered the Orsa "All Bike weekend".
Renewed track and good weather.
Bikes only and some 65 teams are expected, qualification is open
and "run when you feel like it".´4 runs so far and my best is 10,3357.
Waitng for my last slip as they ran out of paper....
Getting warned up and I feel some lack of crunch on the top end, so I will try
some fine adjustment on timing.

Racing

2010-06-29T01:03:00.009+02:00

Season is on, first race was 1/8 at the supertrack , Veidec Malmoe,

Lot´s of rain and only two qualification runs, and I decided to shelf the Ethanol for a while.
Insufficient fuel pressure and starving is not winning any races.

Back to the old Gasoline setup but too late and no qualification with a 6.74 run.

Next was Sundsvall and full lenght 1/4 mile, and again lots of rain and only 2 qualification runs, managed to enter 7th position (8 ladder) with a 10.605 and in the Quarter final I faced one of the quick
Yamaha Warriors and my 10,391/207 km/h aginst his 9,514/221
is not in the same legue, but fun it is.

I notice continued fuel starvation so fuel pump, regulator and suitable
needle valves are now on hand.

I may drop out of the points race due lack of time, as the next two races are just to far away and one weekend after another.

I´m looking at running some match racing possibly at the "Back to basic" days which is opening for the European Championship races at Mantorp Park (Veidec) last week of July.

Some previosly retired Nitro ironheads from Norway may be there and
the track would be top class.

Bike and Engine/gearbox is working fine apart from the fuel issue,
I need more runs to get warmed up.

Test & Tune

2010-05-26T16:56:00.002+02:00

The Dyno test did not go as planned, during the warm up the gearbox suddently engaged as the 3rd gear on the main shaft seized, and taking the gbx out, clean and replace all internals was a nights work, and when back up, we couldn´t get a tach signal which you got to have, so time was up, at least we noticed a severe lean condition on 205 Main Jets.
The good part was that the gbx. did act strange on third gear last season, so now it´s sorted.
Test and tune was on the Kjula airstrip, this time set up for 1/8 mile.
New to me was that during kick starting i got kick backs, so I had to retard which is the wrong way when trying to bring the HP out E85.
The carbs also ran dry before 1/4, and the map indicated I was still lean, I was on 240 mainjets so now I´m prepred with 245´s.
So for the seasons first race coming up this weekend I machined the distributor to allow more movement to get both more advance and retard, I also manufactured fuel bowl extensions including Main Jet tubes which i reamed conical, and I´m sure it`s going to be a groundbreaking modification and leave everybody behind....................
Took the day of and did all the mods and then some, and started up and it start and sounds like

a knuck again, but smells better.

Ethanol

2010-04-12T18:45:00.001+02:00

Started to dial in to the E85, -95 needles and mainjets in the 200 and up range.
Great help from B.I.G who is a good Mikuni and other Carbs shop on the front (west) side of Sweden.
I also did my first starts with the handheld starter and that was a relevating revolution... fantastic, I was in doubt considering that the kick start is rock solid when i´m on compression until I wait out the leakdown for the throw, i marked out the crank position on compression, and the thing just
spun the engine effortless, and chok, chokatook , this thing is just what you need when you

are lost in jetting.

Chain Guard

2010-04-06T03:09:00.002+02:00

A/F sensor boss

2010-04-06T02:59:00.000+02:00

April

2010-04-06T01:22:00.007+02:00

Started and runs fine.
Planning a dyno session at Pro Service but first I will get the motor running on the new juice.
E85 is not that easy to come by as the gas stations switch to 70% Ethanol over the winter (Cold start), and they don´t know what they sell during the period when they phase over to 85%.
Located a supplier and ordered race grade 85% which should get here by next week.
Recorded my current jetting and ordered richer needles for the 45 Mikunis.
As I only use one A/F sensor for the log I had to install one more for the dyno, decided to manufacture it (i know the bungs are cheap) but I have a lathe and everybody should learn how to cut threads....it took me the best part of a day.
Also I beefed up my chain guard, trimmed and installed the Trans Guard which Swecomposite made, and that took me a couple of days as I had to design mounts which can survive.

March and ready

2010-03-14T21:12:00.000+01:00

March 14th and I´m ready to start, that´s a first.
The front head is in place.
The new cam is installed and the only thing left is to figure out
some clever stand that locks the bike with the wheels up if i´m alone and use the remote starter, I´ll dream something up over the week.

Head assembly

2010-03-10T00:11:00.005+01:00

Assembling a cylinder head takes some work and patience.
Done with the guide replacements I got my seats adjusted by Cala in the impressive Sunnen VF6000 and they now check out within .00015" (Inch) when we take the concentricity readings.
It is a big difference to use the mm indicator which reads in .002 mm increments rather than the common .001 Inch, sure it`s the same factual but the gauge action is so much more obvious.

Most of the assembly is like other heads but, getting the valve spring cups, or "tin`s adjusted and the rocker arms shimmed to the right position takes some time and repeated mock ups where one has to tighten everything in the right sequence, rocker arms, rocker box and check free movement, take it a part, adjust do it again, take end play, shim and over again. (you figured right, it´s a lonesome deal and requires a solid rock channel...)
Anyway I use cast Alu. "tin´s" FHP style, and I had to replace the front Intake one, so I prepared a new one never used, and that took some work, as I had to open the spring cup dia. and mill the rocker arm path for clearance, weld and relocate one threaded hole for the cover as well as weld the cover to facilitate machining clearance for the roller .
The old FHP spring cups does not locate like the stock ones with the guide thru the tin but still need some help getting located so I machine the Valve spring bottom cap with a short flange to snap around the guide flange and fit to the hole in the cup. After two nights I´m ready to shim spring height and close up the front head and that´s usually only one night´s work, I´m happy.

Starter Hub

2010-01-24T15:54:00.003+01:00

Allright, time to get busy.
It`s late January so things better get going.
Finished machining the hub for the starter.
Also I got some valuable advice on the starter routine
form the Bikeline Team, Ulf Ögge and his Crew Chief
Ola, Hand Crank using a good quality ratchet handle
to just after TDC, hands off throttle.
If this works allright I´m in good shape for testing
cams and maybe also tune in to E85.
I have to do some homework on E85 ,basically Comp. required and
if/what the Mikinis will react to it, the starter comes handy and tuning in may just be a breeze.

Straight Line Frame

2010-01-14T18:14:00.003+01:00

The latest version of this bike uses a Unique frame.
Unique is the effort to maintain a straight line from the Rear axle to Engine drive.
Way back gearboxes where raised for ground clearance on track bikes but on the "Mother" it´s an effort to distribute load.
Unique is also the manufacturer, Unique Custom Cycles (UCC) did this one for Calas High Performance more than 10 years ago and some details are typical for UCC back then.
I´m lucky to get my hands on this one, CNC Engine mounts, gearbox is raised about an inch and tubes are 4130.
UCC are among the most talented chassie builders and I´m truly impressed with everything that leaves their shop.

Starting the "Mother"

2009-12-31T10:59:00.002+01:00

Kickstarting the bike in the normal setup is undramatic, attention to the condition of the kick gears and cover setup gives confidence.
Last season I ran with a failed Valve spring retainer on the fr. intake and it took me a while to figure. The valve keepers moved and the rocker arm hit the edge of the retainer which resulted in a worn valve guide and oil contaminating the combustion and, starting became a nightmare.
But it is also somewhat unpractical to kick start when on the dyno or when testing different setups.
I noticed the setup used on the Pro Stock Buell´s, like European Champion Ulf Ögge and took a closer look at their hand held gear reduction unit and after comparing it to other alternatives it came out as optimal for my purposes, so its on it´s way from Star Racing.
The Pro Twin Class rules does not allow this to be used in the actual race
so I will have stay in Kick shape....Heavier is better i guess...
The unit gets here next week, its fitted with two motors, reduction gearbox and out of the snout the drive is square, so I'm heading for the shop to manufacture the hub to be bolted on the Crank drive.

Cam and Heads

2009-12-20T14:14:00.003+01:00

Picked up the new cams from Jim Leineweber.
One identical as a backup for the existing
special grind and two with same lift but altered timing
on exhaust, also managed to collect some Woodward tooling for
the head work, which basically is the fr. intake Valve Guide
to be replaced.
Finally I also produced the "Mother of all" valve spring compressors
designed for the 1.5" springs and caps I use.
It´s close to X-mas and we are shoveling lot´s of snow, just like it should be
Have a great X-mas

Viking Raceway is a GO!

2009-10-20T11:35:00.005+02:00

Great news from the environmental court who approved the plans for a dragstrip facility in Hallstavik north of Stockholm.
The crew behind the project had been working dedicated to the project over 13 years.
The plan and the people are no- nonsens with life long experience on some hands and will stay focused on the factual work at hand, the next step.......
Not trying to become the facility for all motorsports but the finest of drag strips, top ten in the world and 2nd to none in Europe.

Stockolm and surrounding communities collects a large number of active racers with no home track, this can be it. Join and contribute.

2009-09-13T15:29:00.005+02:00

Bike is offloaded and cleaned up.
Photographer Finn Boijer took the pic at Mosten Raceday.
New cams on the way for testing and planning of head restoration.
Valvetrain and the fr. intake guide.
Restoration of the holes for the rocker shafts have been on the list for some time.
Should be fair this winter compared to building a new bike.
Will also start the new engine build up, have to make up my mind as I find it hard to leave
the 3, 13/16 bore as bigger bore carries requires heavier Pins and what have you...

2009-09-08T21:52:00.004+02:00

Allright, the "EvilMother" blog is officially started.

Came back from this seasons last event in Mosten, Denmark.
Totally rained away, with one qualification run, but it was sweet.
Dr. Feelgood on friday night was also an experience worth the trip.
Met a firendly crew with a Blown Ethanol chopped 32 Ford 5 window who got me questioning my methanol plans, more about that later.
This blogg will be all about Drag Racing with the "EvilMother" Knucklehead Drag bike and it´s no secret that I am dedicated to run a 9.99 or better single digit on the quarter mile
with the this Ironhead, normally aspirated, kick start S.O.B.
