All I know is that they run on snow I only worked on one down here for a guy that went to Colorado every year, just to clean his carbs because he never took time to keep stabilizer in the fuel. Think it was a Storm 800 92-93 model?. Thought he was lying when he said it would do about 120mph! Haven't worked on any others. OPT

 

From what I see same workings as the quad. Just has 2 cylinders but when I start it it runs a bit. It when I try to give it full throttle it bogs out and dies. I'm guessing its the carb I pulled it and cleaned it once but may have not done a good enough job. May be giving the engine too much fuel. I pulled the carb again probally gonna get it somewhat overhauled by someone else. So it gets done right. It is a tillison carb a bit different than the mikuni on on quad.
