I just got a 94 Polaris sportsman 400 4x4 that has been sitting for awhile I cleaned the carb got it to start and run but I feel like its over heating I know nothing about the cooling systems on these also I notice the voltage regulator gets extremely hot while its idling none of the electronics work on it no lights of anykind head lights nor dash lights I jumped it to get it started also when I got it started it wouldn't go into reverse other then that it looks like a really nice bike no damage what so ever so I imagine with a little work this will make me a nice bike any suggestions would be greatly appreciated thanks.
