Well got my sled running pretty good better than it was. When I sart it up it smokes, normal for a 2 stroke it than goes away if I am riding slow or stop and shut it down for a few minutes then start it again it smokes really bad it is fine when it is being driven. just slow speed and after shutting it down.. I am thinking maybe the injector is out of wack but not sure. I have not checked the compression yet. Don't think it is a compression issue. Oil is Motul oil... I am stumped....
