Not sure if you still have the problem, I will offer a couple suggestions anyway. So as for aspiration, is the air filter plugged? Mice have been know to build nests in exhausts. When you start is there long cranking, idle fine, act like it runs down in power or is the problem cotinuous? Use this to determine weather fuel supple problem or not.

What color is the burn on the plug? I would expect it to be lite gray to very lite brown being a 4 stroke. Black powder indicates over fueling, shinny black indicates oil/ weak rings (compression and leak down test). What color is the spark? The more yellow the weaker the spark. This would cause long cranking and misfires. Well hope I could give something helpful for you.

I do like to ride in Santa Idaho area.

Hi, new from WA. I really enjoy my polaris 400 4x4 scrambler, its snappy. But, being diesel tech I cant help but wounder about the new diesel Quads. Anyone try one yet?
