Hmm, I don't think that hole is supposed to be there. Bummer...
So is there any specific places anyone can recommend for buying NOS oversized pistons and rings for a CB175 along with a gasket kit?
At the moment I'm thinking about just replacing the pistons with NOS oversized ones, And while its over getting the cylinders honed, might as well mill the head slightly to bump compression and calling it a day. Is there anything else you guys suggest I do while I'm in there?
Thanks for your help!
