On my XR600 with it's stock carb, I have trouble controlling my throttle coming off idle. For a while I thought it was my cables, but it's not. I finally traced it to the carb itself and the slide in particular. My theory is that when the engine is running, pulling a vacuum through the carb body it causes the slide to [@#$%&*!] slightly in its bore. When you turn the throttle it sticks then pops loose. I think the popping loose is the time it takes for the slide to get straight.. Anybody else ever notice this? Is my carb just worn out? I took a turn or two out of the return spring and that helped but it still bothers me, especially in tight going. Any advice appreciated. dan. EDIT: "causes the slide to c-o-c-k slightly in its bore" (meaning to get out of alignment w/ the bore) The TT software bleeped me out for that. dirty mind or what?
