Too bad you're not closer to wilkes-barre. I could install jet kit for ya. What I would do If i were you is take it to a good ATV shop and have them see if they can help ya.

sounds more like you need to clean out the carb and change the plug to me, as far as the jet that comes with the hmf... well that is kind of a joke.....buy a proper jet kit and have that installed.... it will run better......

With the Dyno Jet Jet kit, take my word for it, if you have the air box lid removed then defianately install the largest main jet in the kit, Dyno Jet has always recomended a leaner main jet than what you really need, I have installed about 5 or six of them in different quads and bikes and everytime I had to go back in and install the biggest main jet in the kit for the best performance. But with the lid on go 2 less than the largest.

What I always do is put the tires on and if they rub order wheel spacers.
