    Which is the best 13:1 replacement.

    Yes. Used JE in many bikes. Very good quality 13.5:1 for pro series

    Cylinder/piston clearance help!

    Your numbers do not seem right. Typical 450 piston is .045-.067mm or .0018-.0026 in. 95.96 would be typical stock bore replacement size. You need to measure your cylinder to verify clearances. Recheck your manual dont think your looking at right piston to cylinder clearance.
