Today while riding my throttle appeared to get stuck for a just a second. I initially attributed it to possible brief whiskey throttle since my forearms were tired, even though I was almost positive I was off the throttle. About 20 minutes later I'm off the side of the track and open the bike up to 4th gear. I let off the throttle and it continued to accelerated. I pulled the clutch in and lock up the back tire and thankfully after about 2 seconds the bike went back to normal. I called it a day after that.
What could cause this? I'm planning on getting into the bike and inspecting this week. It's weird because the throttle does not appear to be sticking and the slide sounds like its closing in the carb when I let off the throttle. Nothing initially seems to be getting hung up with the throttle and feels to be working smoothly.
Any other possible suspects before I start taking things apart? The bike is a 1999 CR250 (2-stroke). I do not race and ride mostly tracks and occasional trails. It does have 49hrs on the top end but the bike has been running like a champ and had not been showing any symptoms of needing it changed yet. Could this possibly be a symptom some how?
Thanks.

Also check your pilot jet, I've found a lean pilot can make the bike hang in the revs a little. Check your air screw and pilot jet size.
