Handle bar ends

[Dagger969]

I bought my 98 Kat a few weeks ago. I noticed that when I take my hands off the bars (to fix my helmet or jacket) the handle bars start shaking like its gonna throw me into a slapper. My other bike never did this.
After close inspection of the handle bars I realized one is infact a handle bar with the end cap and the other is a pipe. Some one must have ate $hit and replaced the busted handle bar with a gas pipe. The pipe has no end cap on it. Could this be the reason I get the shaking when I let go?

P.S. I already ordered and installed a real handlebar, now I'm just waiting for my endcap to come in.
and I'm now a chicken strip YES!
Thanks for your help guys

Sounds like it might to me but if this doesn't fix it you might want to check wheel bearings, neck bearings & wheel balance.

+2 on the bearings but on the triple trees and also check the others, they usually fall together.

If you have a weight on one end and not the other, it may well do this. Try taking off the matching bar-end weight and see if it still does it; if so, I'd check the tire balance before going any further.

Other possible reasons:
bent/warped rim
warped rotors
uneven fork oil
uneven fork damper settings
misaligned rear wheel (depends on how fast it oscillates -- slow is in the rear, fast is in the front)
frame damages
bad steering stem bearings

Good Luck!
