Scooterotica

Hi does anyone know of any Mods I have to do to fit a px125 engine into my motovespa GT160

i don't think there are any. you don't need the engine bracket and the rear shock distance bolt may need to be shortened, but that is up to you. I have done a few GS150 conversions and the main problem is in the wheel alignment. Best advice I can give is measure the scooter as is, height of gear selector and rear section of frame from the ground. Fit the PX engine and measure the same distances and check for wheel alignment. Let us know how you get on and any problems you have.
