I purchased an 04 king cat 900 last winter and long story short ended up scorching a cylinder due to it being jetted for 6000 to 900 feet and me not knowing any better at the time was running down here at 1800 feet. So now for my question. I am going to Cooke city Dec 23rd and am wondering if any other king cat owners or similar sleds could tell me the best tune for that area as in main jets and jet needle e-clip position. I have purchased 320's, 330's and 340's. I also have completely rebuilt the top end. Thanks
