if i want to put a suzuki ep 175 piston in a polini 177 kit can i just put a p2 crank in the 125 case?

P2 inlet web is wider, so either machine casing to accept lip on crank, (best way as you can run a wider inlet port), or machine lip off crank.
P2 also has 5mm longer rod (110mm) and 1mm bigger (16mm) small end.
Im running a 60mm P2 crank in my Malossi 166 'crosser' engine.

well thats the direction i was thinking . iv got an old polini 177 and my ep piston is 3mm shorter and runs a 16mm pin . so this looks a cheep way to gain power and reliability! gona have a home made reed aswell .
