Title: Chibi 60 cc model number C430 serial 722100

hi,  my son and I are wanting to bring back to life my old mini bike,

we found a place to bore out the cylinder and he suggested we bore out to .50,  the guy asked if we could find out what the piston clearance would be?

Service limits are .0015 - .004 in. clearance, so have your machinist aim for .0015 in.

I have a Tora that has a model of C430, I thought that was for the Chibi.
Is this common of Tora and Chibi to share same model number?
