is it possible or has any one mounted a polini 50cc engine to a biycle? I have recently accuired a polini gp5 engine withbore of 36 mm and a stroke of 39,2 mm.Crankcase and cylinder are in light- alloy. It has direct reed valve admission in the crankcase. The power is of about 14hp. The engine is equipped with a PHBG 15 "Dell'Orto" carburettor. . Im not really sure how i would mount it yet. I will probably have to buy a welder to make up some mounts? Thanks in advance for any advice.
