Use the good old freezer/oven technique?     

jonny500:
just had the bore and piston measured as follows piston = 3.374" / 85.70mm and bore = 3.386" / 86.00mm. this is out of spec by cylimer. is this ok to run or not  :|

kaw rider:
the cylinder is good, but the piston is small or they measured the piston wrong.

Agreed... where on the piston did they measure?

You should have a .008" differance between the piston and bore total (if your running wiseco specs. (.004" clearance)
