I have a 2008 sportsman 500 ho that I bought used with very low hours and mileage. Even with the low hours and miles it appears the machine has never been greased since I don’t see any grease nipples. Its my understanding that the machines come with locations for grease fittings and at the first greasing you have to install the nipples, which is common on other machines and equipment. Does this sound right to everyone else?
