I bet you do! If they sell motocross bikes, there are people who rebuild single cylinder crankshafts. It's actually a crude press to get it apart but just a specific jig to line it all up again and a really simple device to make sure it's balanced. And if a crank builder says he won't work on a scooter crank he's just an asshole. Go to your nearest yamaha dealer and ask who does their crankshaft rebuilding. Someone does it. I know a vietnamese guy that does it with just the press and lines it up by eye and his lambrettas are fast as all hell!
