    i have a 88 warrior and it does the same thing. It idles fine, and i can give it full throttle for one goose, but if i hold the throttle for more than one little goose it just, its like it's being choked from eather air or fuel. I was reading online and someone with the similar situation said it could be the CDI,

Try checking the switch for your parking brake. It is the top wire in the clutch handle boot. This wire connects to your CDI box, and restricts the RPM's while the parking brake is engauged. To find out for sure, trace the wire down to the plug under the headlight assembly and disconnect it. Now try starting you machine and give it some throttle!

I think you have too much gas to air ratio. if u have cleaned carb, u must adjust the jets a little tweaking and some time and you should be fine

My kolpin fourwheeler will idle, but stalls when i give it gas


hello, make sure your spark plug is getting a good blue flame, if not you may need cdi, i replaced one on my atv, would idle all day would not rev up, cdi boxes is the brain of your atv, motorcycles tells it what to do as far as firing, timing advance, hotter fire to plug etc..my atv is a 2000 350 warrior, their known to not have very reliable cdi,lots of problems with warrior cdis....

My 01 yamaha warrior bogging down


Have you changed the spark plugs? If your plugs aren't firing correctly, this can cause the problem. If you have dirty carbs, this can also cause the problem as you will put too much air in and not enough gas.
