i just recently bought a 2006 600 HO i put around 600 miles on it in temp from around 35 to -10 degree and one problem i have noticed with it is that it will load up (so to say) and not go over 6000 rpm when i get on it if i have been at an idle for more than about 10 seconds. dose anyone else have this problem also dose anyone know what i could do to fix the problem.

you might be over fueling and it takes a second for the extra fuel to burn up does it run fine after you get it going

yeah after i get going it is fine but it really sucks when i get stuck i cant get the rpm to get the track going and makes it difficult but i am fairly new at this and i was wondering what i could to do fix the problem

I had the same problem with mine. I went from 420 mains to 410 mains and it has helped quite a bit but not eliminated it completely. Plugs look good so I'll try 400s next.
