I only speak english and french... so if someone here understands it would be cool!

Right now I have a yamaha bw's but I want to buy a Tomos Bullet (a35).
Please tell me:
1) Is it possible to put a cylinder and piston from a yamaha bw's to a A35??
2) Is the Raptor kit the only good kit for tomos a35??
Is it as powerful as a scooter??

3) Does anyone have pictures of a A35 engine, transmission, ... because until now I only had scooters and I never had a moped. Is it very different in performance?
Can you ghelp me upgrade????

Thanks!
