Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The engine of my motorcycle developed a ticking noise after ridding around 750 miles from new,this is noticeable when hot or cold,through a Kawasaki forum I use I found out this is a possible cam and tappets failure to fix may result in the engine locking up causing a possible crash if not death. Kawasaki however where I bought it say it's normal for Kawasaki's to sound like that.”

“I have an 2007 Kawasaki zx6r and I had the same oil leak that alot of people are getting for this year and model bike...I took it to Kawasaki hope it doesnt happen again .”

NHTSA complaint #10240282, filed 2008-08, 2,460 miles

“There was excessive noise, like a tapping, coming from the cams. I go back to the dealer but they said the noise was normal. I cant believe I bought into the garbage. I then look online on the forum boards and a great deal of other people have had this exact same problem. It is extremely noisy from the valve area and I feel as if the valves and cam are going to fail anyday. Everyone else says this is a common problem with this model but Kawasaki will not suck up any cost to fix this. Extremely unpleased with this result in buying a new bike. I will never buy a Kawasaki again. …”

NHTSA complaint #10241120, filed 2008-09, 200 miles

“I own a 2007 Kawasaki zx6r. From day one it has had an incredibly audible valve ticking noise. The noise is so bad that even at 6000 RPM with a helmet on the ticking can be heard. I have taken the bike to authorized Kawasaki repair shops 3 times and they have replaced the camshaft chain tensioner but have not fixed the problem of the ticking. They keep telling me it normal. I have even tried to contact Kawasaki but they do not care about the problem and just respond by saying take it to the dealer. I have also had to replace the valve cover gasket 3 times because it keeps leaking.”

NHTSA complaint #10240988, filed 2008-09, 2,000 miles

“Valve cover leak on 2007 Kawasaki zx6r. Also a 'ticking' from the engine that has to do with timing chain. The oil leak is a danger being that it's on a motorcycle. The 'ticking' is just a little annoying until it causes engine failure.”
