rynophiliac Posted January 8, 2009 Report Posted January 8, 2009 Hey there guys, I have 64.5mm pistons, I was wondering how many more bores i have left on these cylinders? do they usually go in standard incriments of .10 over? how many over is my 64.55 mm right now? thanks for the help Ryan Quote
wacko2000 Posted January 8, 2009 Report Posted January 8, 2009 I believe you are .20 or 30 over When its time for a bore it depends on how deep the grooves/scratches are on the wall. You can bore up to .100 over Quote
Titan up Posted January 9, 2009 Report Posted January 9, 2009 (edited) 64mm is stock, so your at .02 or .5mm over. If you can try to get pistons in .25mm sizes so you don't have cut so much out of your jugs for each rebore. Edited January 9, 2009 by Titan up Quote
vulvafan537240 Posted January 9, 2009 Report Posted January 9, 2009 64.5mm is .020 over. wiseco makes up to .100 over but "big bore" pistons are 68mm and up. Quote
FASTOYS Posted January 9, 2009 Report Posted January 9, 2009 You should have 7 bores left using Wiesco pistons. Quote
klemet banshee Posted January 9, 2009 Report Posted January 9, 2009 sorry to hijack but once you hit the end of your bores is it possible to resleve it with big bore sleves?? Quote
dajogejr Posted January 9, 2009 Report Posted January 9, 2009 sorry to hijack but once you hit the end of your bores is it possible to resleve it with big bore sleves?? Yes...but once you start putting big bore sleeves in stock cylinders, you start running out of transfer room that was small to begin with. A larger piston is only one of the cake ingredients... Quote
