1985 kz1000 police Bike got the vibration

This is a project im working on and ist completely stock. It starts right up and runs good but when i rev the engine i feel vibration in my feet on the floor boards. same thing when im riding down the road. When ideling its there but barely noticeable.
Any ideas what would cause this?
Thanks

Reasen ?
It's a KZ 100, and they vibrate, ecsoecially between 2500 -3000 rpm.
If you just can feel vibration, and not worse than feel, its normal.

:huh: :woohoo:

I was getting a vibration with the stock exhaust system, and wasn't able to isolate the problem until it was removed. Then I found the culprit...loose inner down-pipe on #4. Actually, it wasn't loose, but just close enough to the outer one to exaggerate a minimal vibration. It felt like the motor was going to blow when cruising around 4000rpm.
Not any more.

I have a 79 1000 ltd I'd doesn't feel like this. My feet go a little numb.

Could be a twisted crank. Use a TDC tool and degree wheel and find TDC on cylinder #1 and zero out the wheel. Then move the TDC tool to #4 and see where TDC is. It should be the same, or the crank is twisted.

Ok ill try that. If my cam chain is loose could that cause it? I think I here the cam chain a little bit. I was gonna change the automatic tentioner to a manual one.
