i have 2 650 assaults ,,, sled 1 started on day 1 with engine surge at 5000 rpm ,,, and at no other rpm or speed ,,when you try to hold a slow speed at 15 to 20mph or at 5000 the engine will go from 15 to 24 mph or 4800 t0 5400 rpm with out moving throttle ,, hard to drive on rough or slow tight trails ,,, sled 2 just started same thing at 5000 rpm last weekend ,,, there both at the dealer now, but no feed back from polaris on the problem ,, anyone else have this problem ,,, they have around 800 miles on now ,, and took about 600 miles and 30 hr to get break in finished ,,, ,, thats when fuel and oil seem to stablize ,
