I need some advice on whether this is a terrible idea or not. I've got a 50cc PP hero majestic motor--a weird mix between a laura and a 103 engine-- that uses a clone shaco SHA 12.12. If I could, how bad of an idea would it be to swap to lets say...a vm20 (mainly cause i have one on hand)? I would be putting prolly a shitter circuit pipe on the engine as well. Just didnt know if a vm20 would be too big for an engine that originally ran off a 12.12.
