I have a 2006 Polaris Sportsman 500 HO. Just jiggling the throttle cable makes the engine rev up and down. This can't be normal.

ATV also continually stalls out even after running for hours. As soon as I let up on the gas it dies on me.

Can anyone help?

 

make sure your etc cable is adjusted properly and that it is tight.

 

Ditto. That happened to me and quite recently, w/my Sp450 from the handlebars go down the
throttle cable to the rubber boot, slide it away and you will notice a thumb adjustable
dial, you can tighten and adjust there.

etc needs to have 1/8" free play.

 

Good pt, forgot that one, LOL! - All true, mine is working really nice.
Hey Stendori, I lowered the RPM's to what you suggested and its
as smooth as all get out!

Thx,

R'

 

thats what we want, smooth as butter bro.

Check page 116 of your owners manual, that might help..

 

Also you might do a search of the Polaris forums for "ETC" or "throttle cable free play" and you'll find some tips for sure.

 

Thanks everyone. I'll try adjusting tomorrow and let you know the results. Very frustrating though.

 

Guys,

I couldn't take it anymore. Had the Sportsman back at the dealer for the third time on the same problem. They have already replaced the carb and throttle cable.

My Sportsman let me down for the last time Memorial Day weekend, when it left me stranded 3 miles up in the mountains.

I traded it in yesterday on a Yamaha Grizzly 700.

Had to.

Needed reliability.

Thanks for your support.
