I got a 2005 Honda CR85 with the purchase of my son's JB mod 90. I opened it up the other day and it shows 1.5 on top of the piston. I wanted to use the same piston but am having no luck finding one. Any one help....

If it is showing 1.5 on top of the piston, how much over bore is it. Still learning these little monsters.

Thanks again
