i just bought an engine and the cylinder has PC engraved on the side. it is very nice porting. anyone have a clue who may have done it? :beer

pics added. BTW this came off of a 200x frame!! the guy had it ported to remove the atac valve and said he raced it back in the day. it is a 1985 cr125 engine. the rest of the bike is gone. he had the frame but it was rusted to no use and the pipe was hammered crap.

[Trouble]

it would help to see some :pics: of it.

i would say PC did it haha. could it have been pro circuit....i have no idea if that do porting but being an exhaust company...maybe?

yeah its pro circuit probably, they didnt start as an exhaust company, and they still do all types of engine work and mods.
