2008 Crf 450r bearing out or what? I'm lost.

Ok, so i'm at the part where the crank cases are together and I'm trying out the gears. Without the clutch assembled on, when your in gear, should your shafts be able to spin, or is that a bad thing?

A shop will measure it and hone it for you, but they will want to sell you a piston kit with mark-up.

I recommend picking up the tools for measuring the cylinder, and learning how to use them properly. Even if it is just a rough measurement.
I use telescoping 't-gauges' and a vernier caliper set for a quick shot at the number.
If you want to get a more accurate number, buy a set of micrometers instead of calipers.

Absolutely nothing you or any of us can do without the cylinder spec.
