Well we got a lot of snow up here now so I have been out and about riding. Today my machine seemed to be running fine so I started hitting some drifts and noticed when I was in real deep powder spinning a lot winding out after like ten seconds it starts to bog out and sort of stutter. I noticed it earlier today. Now tonight when I was just out it was running fine and again I hit some drifts and was winding it out for about five seconds and again it started to bog and stutter so this time I started for home and noticed when I would get on the straights and get going fifty to sixty in the midrange the engine would seem to stutter. If I slowed down it seemed fine then if i got on it again it would get up to around the same speed fifty to sixty and would stutter I cracked the throttle a couple times and it would seem boggy sorry for the long explanation just wanted you all to know the facts Soooo can anyone help me out on this as to where to start looking??????? any help is greatly appreciated.
