Maintenance & Technical > KX500 Original
Bottom end/Transmission issues
Good:
I don't have an answer for Stang, but:
My KX5 was leaning up on my old CJ5 idling while I was adjusting the idle screw after installing a fresh jet- a little fat for my altitude, but I sometimes ride much higher elevations than the base. It acted like it was going to die so I "binged" the throttle. Meanwhile, it dropped itself into gear, dug a trench, and died most annoyingly... Now, it is stuck in gear. I don't know what gear as I can't shift, but stuck none-the-less.
Anyone know why or at least have a starting point for me? :?
Thanks,
Tim.

Stang, I recently noticed my countershaft had alot of countertclockwise/ clockwise play on my 250. Switched to a newer sprocket and most was gone. The notches on the inside had become worn before the teeth on the outside. Weird to me. I think those spacers can wear also, and some sprockets are thinner than others. Somethings going on if you can get a washer behind the sprocket.
Good, I have a yz 125 that likes to stick in gear. It always gets into third, and second some how. You can pull the clutch cover and fix it. I have fixed mine several times with the shifter. easiest way was to ride it in the gear its stuck in, and shift up a couple times, then back down, but it doesn't happen that easy. Most likely the parts inside are in a bind in the open or shifting position. Not sure of the right names of parts or terms, but, if you pull the cover and start playing with it, either the 4 pin'd barrel will be caught half way in a cycle, or the flat metal slider with the springs, is stuck extended, or both. It could be something internal, of course, lets hope not. Its likely something simple.

I hate to sound negative but in my experiance it sounds like it gaulded a gear to a shaft. (sorry) :cry:

YES!!! Mine did the EXACT same thing, in the EXACT conditions! You will find a seized (5th?) gear on the main shaft.
I talked to an old time Kawi tech about it and he explained to me that when the bike is on its side stand, the gear oil runs to the furthest point away from the gear/shaft that seized. He said he always slightly overfilled the KX500 gear box and NEVER revs one on its side stand...

And just what was your bike doing leaning on my CJ?!! :-P :-D Just kidding. Thanks for the help. If this is the case, what is the fix? That may seem obvious to you guys but I'm not much of a mechanic.
