On the Kz650 the ratio was 16 teeth on the front sprocket and 42 on the rear sprocket if my memory serves me correctly. You might want to check your bike and compare it to the factory sprocket ration.

thanks i'll check the spockets, but can there be any other problem that can cause this besides the ratio or the tach not working right, ok at 65 the rpms 7500 to 8000, but if i gas on it rpms will go up then drop down some at about 80 to 85 mph what's with that?
That sounds like clutch slippage. Make sure your cable is properly adjusted. Also, what kind of oil ar you using? (Certian "energy conserving" oils cause clutch slippage.) If none of the above is the problem, you need either new clutch springs, clutch plates, or both. Replacement is not too difficlut, and the parts are readily available and inexpensive. Replace the cover gasket too.
