Just out of curiosity me and my buddy who is an engineer were talking about the pros and cons of a propane conversion for the P5... I have heard it can be very efficient but you could loose some power which our bikes cant really afford but done right it could be very fuel efficient for longevity of the engine and oil life not to mention my buddy thinks with a similar sized propane cell you could get many more miles between fill ups... Anyone out there ever messed with anything like this?? Just curious wanna pick your guys brains...
