Yes under warranty bike had 5k miles on it they are replacing pistons oil pump and top half of motor but they could not tell me a cause other then try to blame my ecu flash and tune
If the flash and all voids the warranty, they’d have no reason to warranty the problem. The fact they “blamed it” on the tuning means they know about the mods and if this were common, you’d hear more about other instances. I think we’re making some unsubstantiated assumptions somehow.
If this happened to your bike and it was out of warranty then you would buy all the parts and put it back together not knowing what caused the problem?
I don't think so
That looks like its from bad plating, it flaked off and destroyed the piston. A piston is not going to do that to nikasil. Thats why Kawasaki is covering it.
The dealer is doing the work under warranty and probably have no obligation to explain the cause. Maybe they don’t know or don’t care to know or know and don’t want to say.
I think calling all dealers incompetent is a bit harsh and a general statement. I had warranty work done many years ago and the dealer simply explained what work they did and what the warranty on that work was. They never explained what the cause was.
Same thing with my 14R. My motor spun 2 rod bearings. After fighting with Kawasaki for 4 months, neither the dealership nor Kawasaki could give me an answer of WHY it happened, i found out the answer on many zx14r forums. Kawasaki denied the warranty because they couldnt find the issue. Covered the rebuild as good will since. I have owned 6 kawi’s.
What was the answer to spinning 2 rod bearings?
The 2007 had some #3 rod failures and nobody really had the answer.
Suspected loss of oil flow either from bike laying on it's side or wheelies due to the oil pick up in front of motor
Never confirmed though
Never raced my bike. Just highway pulls and it still failed at 3880kms. Had the dealership install the ape cover when they rebuilt the motor. That was fine but then the cct wasnt holding the chain slack and was causing alot of noise. It was about to jump a tooth at any time so i installed a manual cct.
Update almost 2000 miles after repair 2 out of 4 piston did it again
