I have a 1980 puch magnum mk2
I just bought and installed all my parts from treats
metrakit 65cc kit
and i have an exhaust leak. i have the nuts torqued down at 7lbs and i don't want to go any harder and break the studs. the kit came with a gasket that has a flat metal circle on one side and a ribbed metal circle on the other end. I assume that because the metra cylinder has a little ridge on the exhaust side that the ribbed side of the gasket would go there and the flat metal side would go on the pipe side. Am i wrong? any suggestions?
