Put some real handle bars on it first!
I second the starter shoes, lose them
Go up and tooth or 2 in front (mb5 front sprocket is the same and works)
Flat reed cylinders and intakes work on them
And scooter clutches go in the rear. I have a stage6 for a minarilli horizontal in mine works great! You can use the matching clutch bell but it needs to be machines down a little for it to fit
