so im looking to trade my rhino for a lifted 07 Renegade. But, if that doesnt go thru then i may just keep it. now my tires will need to be changed. whats a good mud tire but still ride good and not be heavy? i ride fairly fast. now is it worth it to sell my rebuilt motor and do a Rotax swap? what all is needed for the Rotax? what would it cost? and what could i get for my rebuilt 04 motor with 47hrs on it? it has Hot Rods rod, rebuilt crank, Namura piston, and everything else in the motor new stock parts.
