I have a 1999 kawasaki 300 praire 4x4 I have owned it for about 5 years now and have spent a few hunderd dollars on it trying to correct the following problem. When accelerating quickly from and dead stop it will sputter and not take off until you let up on the gas. You have to use the choke in order to get it going. At first I thought is was just cold natured but it can be runnning for sometime and still does it. Anyone had a similiar problem? Not a hughe problem for me however just want it running correctly.
