My Stroker built KLX has the Mikuni 33mm pumper cabr and up until now, this thing has been perfect. Suddenly, without warning, the engine keeps a high idle when the throttle is chopped. Sometimes, the idle is quite high, other times it's much lower, and even othet times it's normal. Does this sound like the slide bore is worn and the slide is getting cocked to the side and not seating squarely at the bottom of the bore? I've searched for air leaks and have none. While in neutral, I can blip the throttle several times and it might go to normal idle 50% of the time. The rest is all over the place. If it idles high, I blip the throttle, and it returns to normal.
