dmfisher71 Posted April 6, 2012 Report Share Posted April 6, 2012 ok this may be a dumb question but i have never noticed this before, but i bought a set of 795 series wiseco piston on ebay... they are marked as 65mm (which is what i ordered)... but i measured them both, one reads 64.50 exact and the other is 64.49.... are they supposed to be like this.. my cylinders are on a wore out 64.5mm bore was going up to even 65mm... i have rebuilt many top ends on many different things but have never noticed this before.... or did i just get a "mis-stamped set of pistons".....

Wildcardracing Posted April 6, 2012 Report Share Posted April 6, 2012 If they are 65mm pistons they should measure @64.85mm front to rear below the rings and 64.75 side to side below the rings. We have gotten Wiseco's with all kinds of different sizings and even some obvious mis-stampings in the past. If you're measuring above or at the rings you will be @64.5. Hope this helps. -Brandon Quote Link to comment Share on other sites More sharing options...
