I bought a warrior about a month ago. All I know about it is that it has a dg pipe and a K&n air filter.Not sure if it has been jetted or what size it is yet. It had been sitting for several months when I bought it. I cleaned the air filter, drained the gas put a new plug in it . My problem occurs at high rpms in the top two gears. It almost sound like it is missing. I am new to atvs so any help is greatly appreciated.

 

Check your plug, sounds like a jetting problem

 

I checked the plug after running it wot is was a light brown.. I am getting ready to take the carb off 2night. Does anyone know what size jet should be in there with the mods I have?

 

Light brown is pretty much what you want.

What altitude are you at? At around sea level a 148 or 150 main is what most go with for that setup.
Make sure your valve lash is correct.

good luck,

for some reason my 03 warriro does that too... it's stock totally.... plugs about ooo 4 months old...

 

there was someone one on the forum earlier with a similar problem that was found to be a bent valve. Do you know if the valve adjusting lock nut ever backed it's way off and possibly bent the valve?
