What you need to do is spend the money and get a repair manual. Check ebay, you can find Clymer manuals all over the place there. $20-$30 is not that much for all the valuable info you get. I believe that a manual is an absolute must for anyone who works on their own machines. I don't know much about your machine, but there are a few users herer who seem to be pretty familar with Artic Cats, hopefully one of them chimes in with something for you. I would still get the manual though.
