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,

I´m on it, barely....

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.
