Larry's Shee Posted November 10, 2014 Report Share Posted November 10, 2014 Is 60 over the next size? Never bore more than what is needed to clean up Quote Link to comment Share on other sites More sharing options...
lil Doobie420 Posted November 10, 2014 Report Share Posted November 10, 2014 Jetting seems a lil rich... wiseco all the way. +4 timing. Quote Link to comment Share on other sites More sharing options...
dirtydownunder Posted November 10, 2014 Report Share Posted November 10, 2014 18s @ 750ft, whats that kicking compression ? like 180ish ? i probably wouldnt run much timing advance if any at all. if its an un welded crank, its going to move around a bit with that comp anyway. superstock vitos would be ok, if youre not going to port it, but porting it and getting some wisecos would be a good option. another option would be to true and weld that crank so it doesnt go out of phase.

awblackmamba Posted November 11, 2014 Author Report Share Posted November 11, 2014 I had noss ship me a set of 19cc domes instead just to be safer. I just need the crank to hold up one winter wont be riding it much but goin 4mm cub or serval thinking more cub in the spring. I'm thinking ill start at +4 and see what +6 does afterwards. just got the Mattoon timing plate deff a nice piece looks to nice for my bansh. Also I have to go .060 over the idiot who owned the bike either put the piston in there or got lucky that it didn't damage the head or the case. Just look in my gallery and check the piston out pretty serious to only leave one drag mark in the cylinder sad thing is there is still cross hatching on most of the bore. I bought the vitos ss forged just cause im gonna leave the stock cyl unported thanks for all the usefull information Quote Link to comment Share on other sites More sharing options...
