Re: idle adjustment, i searched

It isn't. Remove at least one seat, then remove the engine compartment access cover and the PVT discharge tube ( two push pins and two clamps). Now you can easily see the black plastic throttle body cover. On the left side (as you're looking from the front of the RZR) towards the bottom of the cover you'll see a lock nut, the threaded end of the cable and a black plastic cover over the hex adjuster. To raise the idle, slide the black cover off the hex, hold the hex with an end wrench, loosen the lock nut and then begin backing the cable threaded end out. When you get the idle you want, about 1120 RPM retighten the lock nut, slide the black plastic cover back in place and complete the reassembly.

One note, if you're having idle problems, say it has started idling at 700 RPM or so, and the motor dies when you stop occasionally, and to get the idle to 1120 RPM you have to back the cable out 1/4". Well, like me, you probably "dusted" the motor.

Best of luck!!!

There is no screw like on a carb. Is that what you're like for?

appreciate it, ive adjusted throttle cable on my first rzr. i know exactly what your talkin about. my 11 is 1300 at a idle, so i need to turn it down. grinds a little when shifting. when i searched i found something about turning a screw so i was a little confused. thanks for clearing it up.

Re: idle adjustment, i searched

You're more than welcome. Nope to carburetor, no idle jet screw. But if you remove the black throttle body screws, you'll see that the throttle cable is on a bellcrank that turns the throttle butterfly. But I'd suggest not doing that. To disconnect my throttle cable to pull the motor finally gave up and uses needle nose visegrips to get the cover screws out. Ordered new screws at the dealer and he wasn't surprised at all.

I suggest you don't use the throttle cable adjustment to set your idle. This isn't what that adjustment is ment for. It's to adjust the free play of the throttle cable - only !!

The correct way to adjust the idle is to adjust the throttle plate set screw. In adjusting this screw - One does have to re-set the TPS. Hence Polaris only recommends taking the machine to the dealer.

Now - IF you want to go ahead and adjust your own idle -- Here is what a modified throttle plate screw looks like and where it is located on the throttle body ........









If you don't wish to modify the set screw - I used a dremmel with their cutoff wheel to cut a straight slot in all of mine -- You can order the KMS tool -- Here's a pic .. ..



And for adjusting the TPS -- Again KMS has a kit .........



Good Luck .. .. ..
