Does the cylinder have to be bored or honed out? I know it sounds like a stupid question but I don't know. Trying to get my budget together for my supermotard.

Depends on the size piston you order(0.030,0.040 etc.) Going 0.030 over you will have to bore the cylinder.

I will assume ( from the title of this thread )
that you are asking about installing the HRC
piston&cam kit into an xr650r.

The answer to the question is then, no honing
or reboring is needed.

I did mine last summer.
