If that Tak Scut kit takes a 68mm piston, then that should be correct.

I don't see why there is so much confusion here. He has a 134, which uses a 58mm piston. you just do pi times 1/2 the bore squared, times the stroke. that is pi * 2.9^2 * 5.5 which is 145.



A 155 is with a 60mm piston (143 on a stock crank)
