My best guess is that you have an intake air leak. You are sucking extra air in somewhere, easiest way to track down an air leak is to spray carb cleaner all around the carb and motor, while listening for changes in the engine speed. When you hear the motor react, you have found a leak. I will be moving this thread to the Suzuki forum and changing the title, please post the year of your machine so I can add that to the title as well.

      I need to know what I have and what tire really go on it, Mine has 24x11x10 on the back and 22x8x10 on the front and I need new tire but I don't think are the right size. Also I can't find the model number listed but it looks like a 250 quadrunner 2wd and I think it is a 1987 maybe, can anyone help me, also I it has a rich running sound and I put a carb diap in it and cleaned the carb. is there a jet needing replaced?

      I have a kq 450 4x4 that I an have a problem with.the bike does not want to move.i am not very familiar with the sheave or clutch that it has on it.my buddy who owned it beat on it prolly never maintained it just so that's out there. The belt is fairly new primary and secondary clutchs are pretty ruff looking the rollers are toast I think but idk. Everything moves fine except for the primary it moves but does not push in to move the belt only at a high rpm will it move sometimes any clue on what it could be other then going out to spend 6 or 7 hundred on a whole new assembly of the clutchs
