I just got my zrx1100 and holy smokes do i love it, i use to have a cbr f4i but sold it for my zrx. I only have 1 problem with it the gauge cluster rattles at 4 grand has this happen to anyone else and how can i make it stop?? Oh and i tried to tighten it so thats not it.

 

welcome to KF. post sum pics when you geta chance.

 

It may not be the cluster, but the fairing itself.

But first take off the fairing. Check the screw holding the cups on the bottom of the gauges. They can work loose and the cups will rattle. You will have to take the gauges off to check the next thing. There is a black bezel around the turn signal / neutral / hi beam indicator. The screws under it can vibrate loose. Next thing is the "dashboard" inside the fairing. Take it
out and put some double stick take between it and the fairing. A vibration comes from there too.

BTW, welcome to the board. I have 2 ZRX 1200's myself. Don't be afraid to ask me questions.
