anyone ever hear or seen a trx 250r bottom end with a polaris scrambler 400 top end??? If so whats it like??I know that this mod can be done and i plan on doing it for a polaris predator. remover the pred engine and install this set up. The engine uses a odyssey 350 rodon a 250 crank and the scrambler 400 topend which needs a small bit of machining. I know drag guys have done this before.
