In your pic, the crank is in backwards

I understand that, but for the bearing with the circlip slit to ride in the circlip, you have to put it in backwards.

 

All I did was removed the o ring from the one bearing, put it in the other bearing and flipped the crank. Everything seems to be ok now. They just put the o ring in the wrong bearing from the factory obviously

Finished porting the cylinders, ordered VF4 reeds and CPI inframes.

Dropped off to Dunetoyz yesterday for domes, inspection, assembly and dyno.

Will update with dyno numbers, have ported about 4-5 jugs, this is the first I dyno. Excited to see results.

Any guesses? 4mil dune ported by me with cpi's and pump gas domes....
