Just bought a brand new 2006 model 250X and after 116 miles of pretty tame riding, I'm getting an uneven idle. The idle speed will periodically surge for a few seconds and then go back down. Seems like it happens every 20-30 seconds when idling. Also, after a couple of hours of stop and go group trail riding last Thursday, I had to cut out early and took the dirt road back to the parking area. After a few minutes of steady throttle down the road, when I reached the parking area, the bike would bog when I gagged the throttle. I tried to replicate the problem by going up and down the parking area and tweaking the throttle, but it did fine in the confined area. It's like it had gathered itself. This was the coldest day of riding I've done on it, but it was still above freezing and by the time I got back to the parking area, the temps had risen to about 50 degrees.
