I just bought a 03 660 and took it out for the first time this weekend. I was following behind another quad and it my quad would bog down and stall if I got on the throtte quickly after lugging around on the trail. It seemed the quad had too much fuel. If I was going hard it would not give any problems but get to the technical slower stuff and the it would stall out when I get on it. Could this be a jetting issue or a carb issue or something else.
