Oversize rings

[JonnyB]

Ok, stupid question comming, ready?

I have to have a barrel rebored, now if I get oversized rings, do I need over sized pistons as well?

[SteveD CB500K0]

Yes.

Last time I did this was on a mates G5 CB360. We didn't bother with the pistons and the rebuild lasted about 3 weeks!  And you thought you only got piston slap on a two stroke...

Thanks Steve

Mmmmmmmmm, This barrel is suffering from a light dusting of rust, a score mark and a some usuals marks I cant explain, I thinkl I'll got for new pistons and a re-bore
