Hi,all

I have been enjoying motorcycle racing with Moto Morini 250V since last year in Japan.
But unfortunately a week ago it’s cam belt have raptured!!
Now I have a plan to swap 250 engine to 350 one on eBay.
Is there any problem on this plan?
Is the mounting points on engine and frame of 250 and 350 engine identical?
Hoping my racer will be faster!

Hello,

This conversion has been done in the past by a Clubmember. Engine fits in the frame, but you will probably have to make different downpipes (from engine to exhaust/mufflers).
