wacko2000 Posted January 8, 2009 Report Share 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 Link to comment Share on other sites More sharing options...
Titan up Posted January 9, 2009 Report Share 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.

vulvafan537240 Posted January 9, 2009 Report Share Posted January 9, 2009 64.5mm is .020 over. wiseco makes up to .100 over but "big bore" pistons are 68mm and up. Quote Link to comment Share on other sites More sharing options...
FASTOYS Posted January 9, 2009 Report Share Posted January 9, 2009 You should have 7 bores left using Wiesco pistons. Quote Link to comment Share on other sites More sharing options...
klemet banshee Posted January 9, 2009 Report Share 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 Link to comment Share on other sites More sharing options...
dajogejr Posted January 9, 2009 Report Share 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...
