I'm not talkin about these guys that do a little port work on the exhaust, and throw a thick base gasket under the cylinder, I'm talkin about someone who could take an already trail ported and piped MachZ, and Wick it up on pump gas. Somebody who knows ROTAX, and can get that extra hp that I'm lookin for. Looking at guys like Cudney, Don Emery, and Lanny Benoit, are there others or opinions???
