I recently bought a 2004 Suzuki DR 200. It runs quite smoothly, except for one problem. The throttle gets stuck. I'm pretty sure it's not a cable issue, because when the throttle is stuck, it is still hitting the idle screw with no problems. Also, sometimes when I come to a stop in 2nd gear, I can ease the clutch out a couple times and it will stop revving up until I take off again. Do you think this is a problem within the carburetor? Would cleaning it fix this problem? Possibly the butterfly valve is the problem? Thanks! Any information or suggestions help!
