2011 Kawasaki Ninja ZX-10R Problems Identified - Web Exclusive

Kawasaki Heavy Industries has revealed the cause of concern and the countermeasure to resolve the issue.

Jan 3, 2011

Having suspended the public launch of the anticipated 2011 Ninja ZX-10R to investigate a technical issue, Kawasaki Heavy Industries has revealed the cause of concern and the countermeasure to resolve the issue.

It was discovered that when some examples of the new 2011 Ninja ZX-10R were operated at high RPM under unique riding conditions – such as on a racetrack – the intake valve springs could surge. When this happens, it could cause one or more intake valves to seat improperly, resulting in poor engine performance.

Having examined the small number of machines that exhibited this surge phenomenon, the Kawasaki factory engineers designed and tested a countermeasure to solve the problem without affecting any facet of the new engine’s performance.

On the limited number of machines produced so far, the camshaft, intake valve springs and spring retainers are being replaced to prevent the valve spring from surging. The same update is automatically being incorporated into the ongoing production run of the newest and most powerful Ninja yet.
