so here’s the deal, I gapped the piston ring, was like butter. oh so smooth.

still, piston was getting stuck at bdc.

had a few buds over and after a few barley pops we figured out that the BACK of the piston was HITTING THE CRANK at bdc.

needless to say, i Dremeled and sanded all night and matched the back length of the piston to the previous piston since we are only increasing bore, not stroke, with the kit.

the stroke is 42 on a 504, 44 on a 505. i’m

going to reinstall everything tomorrow morning. wish i had a 505, oh well...

to think, we thought it was a clutch issue... thanks barley pops. hopefully this will be helpful to someone, some day

stay tuned
