Ive heard of this problem before on other atv's and dirtbikes but i dont remember what its called and how to fix the problem. Ive got a 97 warrior and every time i hit a jump or go over a big hill, it stalls for a second and then the power comes back on. I remember reading about it in all the atv and motocross magazines being the sudden altitude/air changes in the carb. Can anyone tell me what the fix is on this. Someone told me its the venting on the airbox and the carb. Thanx

 

Check the float level and give the carb a good cleaning.

 

Make sure you accel pump is working good and that the boot isnt torn or that the spring is replaced with a better one like the one from a clicking pen,and theres a plastic ring that goes over top the mainjet that is supposed to help with that when hitting jumps, the inertia of jumping makes the fuel lift when you jump and it starves it of fuel for a split second.
