Vibration!
KXcam22:
The KX500 crank alignment seems to be quite variable from the factory. The better aligned, the less vibration the bike has. Some vibrate LOTS while others (like mine) don't vibrate at all. You can try to dampen the vibration but unfortunately the solution is to take the crank out and send it someone like Stewart to have it trued. Cam.

Hmmmmmm very good to know. I am now thinking about having that done as well when I pull the bike apart again this winter to rebuild the bike again and sharpen it up. Thanks for bringing this to my attention guys!

My brother had one with no vibration at all so his other K5 he sent that crank, piston, and flywheel to crankworks, came back it was smooth as silk. My first K5 when I went the 540 kit I took that rotating assembly to crankshaft dynamics which is right here in central PA , and alot cheaper, and he did a good job ,bike revs straight to the moon , it doesn't have to fight through the vibration.

when i first got my '01(it was very abused)it viberated my teeth out of my head. come to find out it had a busted motor mount. im not sure how far u have been thru it, but some times its some simple stuff that help(i hate spending money on something when i could have been a simple fixs)

i remember reding articles in the 1990's were team green would balance rank, use a rubber bar snake, weighted bar ends, carefully bolt engine bolts and i think they had some rubber washers
