I'm sure this has been talked about before, but what would prevent someone from fitting a manual transmission to a snowmobile? I mean, there are offroad vehicles like ATV's and dirtbikes that people have no trouble with, so why not a snowmobile? With all the fiddling and power losses involved with the CVT, why not just go to a clutched manual and be done with it. More efficient and more fun to drive. While they're at it, lose the thumb throttle and go to a twist grip. Other than potential mechanical obstacles, I see no reason why this wouldn't work. Perhaps I'm missing something here.
