it sputter s at full throttle,thats how it started now it does it even at half throttle .it just seems to keep getting worse ,does anyone no what the problem could be.some one said it sounded like the floats were sticking .please help .it bone stock 98 i haent done nothing to it.

 

[img]i/expressions/face-icon-small-smile.gif[/img]You might try pulling the carb & removing the bowl,spraying the entire carb with carb cleaner & blowing it dry with an air compressor. After that, gently raise & lower the float to be sure there is no binding. Notice especially the pin on the float valve under the tang to see whether it compresses & extends as you move the float. If the pin doesn't move freely in & out, you aren't getting a steady flow of fuel to the carb. Also check the gas cap breather hose for kinks.

 

my 2000 warrior sputters when i hold it at full speed for a long time because of the revlimmiter i dont know whats wrong with your and half throttle it might be something with your rev box

 

Does it do this all of the time or just occasionally?

I'm guessing that it is the rev limiter. I would make sure that every connection is tight and secure.(around the handle bars)

 

well first of all warriors dont have a rev limiter mine is the total oppisite is suputers at low end your trouble must be a switch for the reverse or park brake the miss up top might be valves floating

 

all stock quads have rev limiters, and alot of newer ones have safety rev limiters for when you try and drive with the parking brake on, including the warrior. check it out like perrya and warhead said

But I think hot_shoe may be on to something too, check out the carb, if you have bought it in 98 and done nothing with it since you may have dirt or something clogging the main jet (half-full throttle) and it probably need a good cleaning anyhow.

 

thanks everyone ,for your help

 

not allstock four wheelers have rev limiters i cant think of a yamaha that has one so check your valve springs or order so good heavy duty valve springs this will stop your valves from floating up top but most likey it is a bad switch just un hook the park brake switch its right under the hood it helped mine more then you can imagine!!

 

The ground wire on your reverse lever switch is a noted problem.
As a fix, attach a piece of wire behind the screw that is holding the ground wire. Loop the wire around the upper frame and continue to loop going to the battery. Ground end of wire to ground of battery.

If this does not fix your problem, then coil could be deteriorating.
