Bought one without an owners manual and not sure about grease zerts...anyone have one that could help? Not showing any problem but want to do proper maintenance! Thanks!
Check out the Polaris website. They have the owners manuals available for free download. You might have to download the "Universal ATV manual" for your year model as well as the model-specific supplement which has stuff like fluid capacities and some part numbers I believe.
IIRC, the older Sportsmans have a lot more grease zerks than the newer ones. My 99 has ~20 in total. Newer ones have much fewer. The locations are pictured in the universal manual for my model year so maybe the same will be for yours.
