I have an 86 polaris indy trail. This is the first snowmobile that i've ridin since I was a little kid. I took it for a ride the other day, it was making a loud noise, almost like a clicking noise. Then the belt snapped, I changed the belt and it seemed to cure the problem, then the noise came back. Some people told me that I need to adjust the track, so I played around with that today with no luck. I found out that if I sit towards the rear of the sled then the noise takes a little longer to start. Does weight come into play when adjusting the track? Does anyone know what else this noise could be and how I can fix it?
