Check the throttle cable adjustment by the handlebars.

 

i'm no mechanic but check this out... see if the vent tube under the seat got pinched, it should be by the snorkle.

 

The cable seems ok.Any change does change the way it runs .The vent tube also seems ok.Any good way to set the cable,or is trial and error the best?It is touchy.I worked on it last night and didnt get anywhere.I will try again today,that cable is sensitive.Thanks for the help,any other comments would be cool,since i still have a problem.Thanks[img]i/expressions/face-icon-small-confused.gif[/img]

 

Adjuct the cable until you have 1/16th inch of play in the thumb throttle. Also do a seach on all the atv boards, you should find a lot of helpful info.

 

ITS FIXED,THANKS GUYS FOR ALL THE HELP.YOU ROCK

 

Tell us what the problem was, if you don't mind.

thanx

 

I am hoping someone can help me. I have a '97 Polaris 500 XPlorer. I can hear the drive belt rubbing the plastic case. It has an bolts to adjust the cover, but nothing seems to entirely fix the problem. Any ideas???

Also, the rear brakes squeel terribly when they get wet. Pads are good. When I lubricate the spline that the rotor floats on, it helps. I can't seem to narrow it down. Any help would be appreciated...Rob

 

The older clutch covers were very thin and very close to the clutches. Heat over time will shrink the cover and also inadvertadently pushing up against the cover when riding will cause it to rub. You have two choices, put up with it as long as you can until it rubs a hole through or replace it with a 2001 or newer cover. 2001 and up on the 500's got an updated cover which is thicker and slightly further away from the clutches, the outlet size was also increased to allow better cooling. In 2003 the cover's got a drain plug added. My cover has been rubbing for about 2 years now and finally the last time I went riding it wore a hole through. Sorry, can't help with the brakes.

 

Try trading your polaris 500s in and buying a Suzuki Vinson 500, that would solve all of your problems.
