Magic @ Tierp Arena

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

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

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

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

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.

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

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,
