I was out rideing and my friend took my sled for a rip and said my tack was loose. He said the drivers were slipping. We flipped the sled over and looked at the track and drivers. They were all there and the track diddint seem that loose, atleast compared to the other sleds there. We checked the chain case and there doesnt seem to be much play there so I am almost posative its nothing in there. The clunking only happens when I am accelorateing really hard and hooking up. I first thought it was the track hitting the dirt and makeing that noise when it ripped up the ground. I tightened the track up a little bit. And the noise has seemed to lessen. How tight is too tight. How loose is too loose. What are some things to check for when i am doing this? Would there be something else makeing this noise that im not aware of.
