30 minutes into riding cruising 65mph motorcycle all of a sudden started making a clack clack clack noise, lost power, rpms started dropping, clutched in and coasted to side of road, bike shut off, would not turn back on. Kawasaki dealership diagnosed problem saying engine would not make a full rotation.
Valve cover gasket and o-ring for the sensor on the front of the engine leaks oil. Oil leaks daily. Valve cover gasket and o-ring needs to be replaced. Oil leak can grease the tires of the motorcycle and cause a serious injury or death.

It leaks oil consistently. This is an on going problem with the 07 and 08 ninja zx-6r.. This is a hazard because if oil reaches our back tire we will end up sliding which could potentially cause serious bodily harm, property damage and in sever cases death.
