I think it shows up as a different part # but the one u get is that one I said. hear it is (its #1)
DIRT CHEAP ATV PARTS' 2000 Polaris ATV SPORTSMAN 500 (A00CH50AK) (MEDIUM YELLOW) Parts List
its very possible that its your speed sensor I would hate for u to buy the wrong part because of me
hopefully some one else will chime in with more help
I would at least unplug the speedometer and see if any of the connections are bad like corrosion. you may also want to try and figure out witch wires go to the sensor and use a ohm meter and see if it changes as u speed up (might want to use a jack to pick up the back wheels and be ready on that break. and have a friend check for ohms)
I wish I could help you more. but I will try to help u the best I can
ps don't try to take the speedometer apart (unless u got nothing to loose) I tryed to fix mine and I ended up breaking it more.
