Hi Garrett - I'm in a similar situation that you are. I got a "shed salvage" from my dad. 96 model of the same 4 wheeler you have. He had a cam shaft replaced, then shortly after, it simply stopped running, so he parked it in a shed and abandoned it. It has been sitting for between 5 and 8 years, and he gave it to me this spring. I had to go through pretty much the entire thing to get it running. Found a new (Chinese) carburetor on Amazon for about 45 bucks as well as a pair of brand new front calipers for the brakes (complete with pads) for 60 bucks on Amazon also. The rear brake caliper is discontinued and you will be lucky to find used ones. That same chain guard that you are looking for is available used for about 90 bucks. Best advice I can give is before you throw any part away, be sure replacements are available. Most items can be refurbished or made useable again. I've put about 20 miles on it riding this weekend and was overall pretty happy with how it performed. The parts I purchased for it were - Brake handle/master cylinder, battery, 2 new rear tires, both front brake calipers, rebuild kit for rear caliper, carburetor, and misc seals and o-rings. All told, I've got about 600 into it. Similar ATV's are still selling for 1300 -1800, so it's definitely worth it to give it some TLC and get it running.

Yeah, the front brake calipers are easy to find. It seems for just about anything engine related, you are going to have to pull off the gas tank. Fun fact, the way the gas line is routed, it is easy for it to get pinched when you put the tank back on. I think that's why it originally stopped running for my dad after he had the cam shaft replaced. Tank was half full, petcock was open, but the fuel lines were bone dry. Given the age of the machine, it's a good idea to replace the fuel lines and filter when you are working on it. Another thing to check while the plastics are off is the thermoresistor that runs the fan. It's located right at the back of the radiator next to the fill cap. It's another discontinued item, but you can jump the wires together to cause it to run continuously when the key is on.
