Stock Stroke, 54mm bore, why not?

88kits (52mm bore) seem pretty popular, anyone mucked with a 54mm piston on a stock crank (95cc)? I know I have to bore my cases, but I'll be using new cases anyways so I'm not concerned.



I'm looking to make a mild 'play' motor with my spare bits. I have a good crank and 4spd bottom end, and will use a stock ignition setup along with my tweaked auto clutch. I want more than 4hp, but I don't wanna go crazy, so I'm thinking a nice revvy 95cc will be a fun toy. Anyone tried this combo?

its not popular because the case mods needed, and your going to be underbore in most races.


I won't be racing this motor, this is my winter put around motor so I can leave the race one on the bench getting tweaked for next spring. : )



I'm just contemplating different setups. I didn't see it mentioned that often, but I like the idea of decent displacement without crazy piston speed.
