RE: Help with JBA 120 2-stroke (ringed)
You can save a lot of time and the cost of fuel on a engine like that. Break-in will be faster...a savings for sure! The thing to do is get a Frank Bowman custom made piston ring for it. About 15 min of running the engine should run great. Go to engine conversions and read about Franks Piston rings.
