Question about 2001 kawasaki ZX-9 R Ninja

1 Answer

I just bought a 2003 ZX9R and after a few rides there is a loud tapping sound as well as a sucking type sound. My girlfriend and I went for about a 40 mile ride lastnight and when we got there the bike was making those noises and had a slight miss to it. Please help. I love this bike and it is in great condition and only has 26,000miles on it and I dont want to mess the motor up

    Also wanted to add that it did not make any of these sounds when I test rode it or night that I bought it. Also like when im at low rpm's just cruseing it feels like its serging would that be caused by me being in to high of gear for that speed and rpm's? what gear should I be in or would be good for what speed and rpm's ? because I dont know how high the engine and the rpm's can rev for periods of time.

Do you have any idea where your noise is coming from ? if its under the tank it could be a few different things, maybe a spark plug backed out ? also there are some hoses for the clean air system that are under the tank, your're likely going to have to remove the fuel tank and take a peek.

Check your owners manual for a list of common noises it should make to see if it's on that list. Does this have an icemaker? That time frame could be an ice maker valve turning on for a few seconds to fill the tray (or dumping ice).
