Posted this in general, too, but realized I should probably ask the experts... So I took my YZ400 up some logging roads. About 20 mins into the ride, I'm coming down a hill, I left off the gas coming around a corner, and when I go to open the throttle up coming out of the corner, the throttle sticks and won't turn. The bike dies on me. It won't restart for a bit, but I finally get it to fire up...after sitting for a few, the throttle had loosened back up, but as soon as it's fired up, I get about 20 feet down the road and it does it to me again. I finally managed to get the thing home threw it in the garage, haven't had time to deal with it lately...anyways, I start it up last night, same deal, kick start it no problem, go to twist the throttle and it barely lets me twist it, maybe a 1/2 inch, and it just hits a hard spot and won't twist any further. Anybody know what this might be? The engine starts and idles just fine, but I can't get the damned throttle to move...and no, there's not a rock stuck up in grip!
