Welcome to the forums. First thing you need to do is turn your cap locks key off. Second, if you spend some time searching the forums will will find out lots of info on preseason how to's. Like stormrider said, its chaincase, don't use ATF, Amsoil makes a very good chaincase oil, even the OE Polaris stuff from the dealer is ok. You can also use a 75w90 gear oil ( synthetic preferred ). Couple of the big things to service are carbs, clutches, suspension & chaincase. Clymer manuals have enough info to get you by or if you feel rich, buy a service manual from the dealer, all kinds f good info. Good Luck.
