I have a PK80 motor in a schwinn legacy, on its second tank of break in gas (5oz of mix per gallon).. I've put a New fuel line in it, NGK B6HS spark plug, and New muffler gasket.. I wanted to take it into town this afternoon, but wasn't sure if it was too early in the break-in process for a trip that far. Mostly flat, paved terrain the entire distance.. I'm 230 lbs, not sure the elevation but I'm in Lawrence KS... Any help or suggestions would be appreciated!!!
