Should be there also. SP Quote Link to comment Share on other sites More sharing options...
4stroker Posted January 23, 2009 Report Share Posted January 23, 2009 yeah im pretty sure the side of the wiseco box says 0.00297" close enough to 3 thou! Quote Link to comment Share on other sites More sharing options...
TJScott Posted January 23, 2009 Author Report Share Posted January 23, 2009 .076mm is about the same right? see when i bought the piston for my rm125, it said it on a little paper, i looked all over for where it said this but couldnt find it, i guess because it was right in front of my face.
