Put a thin headgsket in it, use the clutch setup from the Techpage. Find a used set of plastic skis,, the stockers are useless. The pic in my avatar is my 97 XTC with electric start and reverse. I did the mods I listed, and installed GYTR all-purpose skis. Also added a 1" predator with no studs, Pioneer Performance revalved shock's ,and Yamaha Mirrors. The oil pump WILL fail, but when they do, they fail at full oiling. The pistons had an issue with the oil ring retaining pin falling out. Not trying to scare you, but with 8500+ miles on mine, I've seen most if not all of the issues these sleds have. I have 2 of these, and the other is all stock. I let newbies and the kids ride this one because it rides great, is warm, and won't let them do anything to stupid LOL. Enjoy your new to you ride.
