Wondering how it would do. I see they run up to 8.0:1 comp, Bump that up a point as it is air cooled. Make about 2.1 hp in a 49cc. Yea they weight a little more but a hollow camshaft and lightened crank would help. Re gear it. They make a lot more torque, Which could be a bad thing. Wonder what clutch differences would be (size wise) . After I run this 2 stroke a bit I think Ill fart with one. Thoughts?
