I bought a pair of these to avoid spending $95 each from Polaris for my XC 800. While pulling the carbs I was able to figure out I only needed to use one. About a week later I had a float issue with a different machine 99 XC 500. Since I now had an extra I tried it and it works in both TM 40 and TM 38 carbs. Time will tell how they hold up but so far so good!
if you click on the fitment icon, it doesn't list the 02 xc 500 as a sled that this product fits but it does fit my sled. my sled is an xc 500 but not a xc 500sp. it doesn't have power valves or throttle position sensor. I assume that the non sp version of this sled is more rare and that's why it isn't listed in the fitment section.
