Hi, I'm new. I have a (brand new, 0 miles) 2003 XR650R that is stock. I was on my first ride this past weekend and the elevation was about 5000 feet, temps about 70 to 75 degrees. After about 15 miles of riding, the idle would stay high. I for sure had the choke off (I'm picky about that, just enough to get it started). The throttle cables seemed loose enough. I checked. The idle would drop back down to normal if I released the clutch a bit, to drag down the RPM's to what was a normal idle speed for the last 15 miles. It didn't take much load to bring them down and then they would stay down at a regular level. Do you think it's valves? an air leak? ??? Anyone got a clue? The engine sounds very smooth, but it does pop on decelleration, especially when on a hill and w/ the throttle completely closed. Can someone point me in the right directions? I'd like to get this handled before riding again. (so I don't mess it up) I have the parts for unchoking ordered, but really want it running right before I actually make those changes. Help?
