Hello everybody,
I just got a zx-14R 2012 with 1900 miles with a power commander and brocks exhaust system, the bikes runs great but around 4000rpm in the first and second gear I can hear a vibration noise coming from the bottom of the bike that disappear as soon as I pass the 4500rpm, I do not feel a vibration of any kind I just hear very annoying noise. The noise is like if a bolt is loose and a washer is vibrating around it. I inspected the bike several times but I can't see anything wrong. My exhaust pipes have little springs all over and all them are secure in place and cover with a clear hose.
Does anybody have experience something like that? FYI I checked my chain and it is fine. Let me know if you have an idea of what this could be.
Thanks
