My Polaris all of a sudden on Saturday decided to lose acceleration. I can slowly depress the throttle, until a certain point, the vehicle then seems to sputter and such.... On the flats I can get it to 50km/hr, but as soon as I go up a hill it slows down and if I try to depress the throttle anymore it sputters.
If I am stopped and just punch the throttle it sputters right away.
It seems to be idling just fine, and if I don't punch the throttle I can get it going, but as soon as the throttle gets to a certain point it just loses power.
