Hey guys, I bought a used 2006 sportsman 450 last summer, and almost imediately I noticed when putting it in reverse, going uphill it stalls out. It's like it's starving for gas, if I keep my finger on the throttle it will die out. BTW it seems to be a very high speed reverse, which I really don't like. When I put it in high range going uphill, I dont have the same problen as reverse uphill...it performs fine. Also, when moving forward, it almost always has a split second of hesitation-but when it does grab hold-it's off to the races! The only thing I've done so far is changed the soleniod and the spark plug. Any help is appreciated.
