I went out to cooke city over thanksgiving and believe i was having issues with my secondary. Im running the slp pipe set and went with the springs that were recommend. Black purple in secondary and blue/pink in primary. When going down the mountain after a climb and tapping the break it sounds to me as if the secondary is ratcheting. Some of you may say thats normal but I assure this is not. Only happens down hill and sometimes happens when im not even touching the break going down hill. My track i believe has locked up on me down hill as well after touching the break. I brought it to the gas station dealer exon in cooke and he changed out the primary back to stock for me. That helped a little bit. He took the secondary apart and said that was fine. I would of put the stock spring back in the secondary if i had had it. The spring he would of sold me would of been the one i already had in the secondary and is close to stock anyways. I have the sled home now and installed the stock secondary spring back and I guess I will see what happens.. I doubt the dealer will be able to tell if anything is wrong as they'd need a hill to go down. Thats why im asking you fellas... My track does hang 3/4 of inch sag with no weight on it. I fell like thats definitely to loose. Could that of caused this issue?
