I recently picked up a 1993 polaris xlt 580 special with 5100 miles for a pretty good deal. According to the guy, the engine was completely rebuilt 1000 miles ago to put in some after-market pistons (he wasn't sure what brand or anything because he wasn't the one who did it) and some parts of the clutch aren't stock. This is my first sled, and there wasn't an owners manual, so I picked up a clymer's shop guide for it. Overall, the sled looks like it's in pretty good shape, the engine runs great and everything, but I noticed a couple things, and I don't know if they are a problem.
1. When I first got it and ran it in the garage, I noticed that the throttle trigger had a bit of play in it, and if it was at neutral and it angled down, it would kill the engine. I was curious why it did this because it was slightly obnoxious, so I took apart the throttle box on the handle bars, and found a loose wire that was barely connected to the kill switch. I disconnected it, and it seemed to go away, but I'm not sure what the purpose of the wire is...
2. Some coolant is slowly leaking around the water pump. It seems to be a steady, slow leak, and I'm not sure if it's a problem worth addressing.
3. The oil line leading to the oil injector to one of the carbs is leaking right where it connects. Once again, It is a very slow, steady leak.
Also, I was wondering if there is anything I should check after getting a used snowmobile like this? The guy I bought it from didn't have the sled for very long, he wanted something bigger, but it sounded like he didn't do much to it and for it.
