if you had 62 and went to 63.5 you'd loose 2 tenths of compression which would be not much at all

i ordered them on a 62cc, but i received them on a 63.5cc is what happened. and was wondering if it was something significant.

tear down in process.

forgot to crank engine with #1 plug out to get close to tdc.
heads are coming off shortly.

i think i can do it manually once the heads are off, get tdc that is.

feedback greatly appreciated.

THANKS!

hey, pdd,

yes, and that is why i was concerned, going from 11.35:1 to 11.13:1
i know "our" cams like high SCR, and the 11.35 was good for it.

i hope ii is not noticeable.

thanks.

Two tenths of compression difference is going to make absolutely NO noticeable difference....

11.1 SCR is plenty....its the DCR that really matters anyway...
