It might cost that much to do it. But 15hp from 80cc isn't a ridiculous number. You're actually going to make me do this aren't you? I'm not willing to go that deep money wise. (I'm not about to start ordering forged pistons, and having combustion chambers custom machined) But 5hp? Sure, I'd be willing to go for that goal.Going to take alot more than a dremel. I'm sure nero could enlighten me with all his knowledge. You tune one of these to 15hp and I'll send you a thousand bucks for it, sound fair??
The Honda MB5 made 7hp with a 49cc 2 stroke. Air cooled, no oil injection, nothing silly. The disk valve, air cooled, TS-90 in my garage supposedly has 19hp.
If you want to be really silly, so long as we weren't trying to do it for a long period of time. There's no reason we couldn't try for RS50 horsepower levels. That little "moped" makes 15hp. In factory tune.
I don't have one of these motors yet.... Do any of you have the inclination to port map one for me? And give me some idea of the RPM ranges these motors are designed for?
