piaggio a/c 50 engine

i need a new a/c engine for my brothers typhoon the upgear kit has ripped the gearbox apart and broke the casings.

I dont mind the engine to be bear but i would love if it had a good crank and bearings. doesnt need anything else as the old engine is perfect and complete.

cheap as possible. can collect within a certain mileage

 

im now after a fully working engine. preferably for a typhoon with the right gearing.
