I need help i can't figure out where the noise is coming from on my gixxer. somewhere on the head.
At idle it rattles like something is lose. it makes that rattle noise until about 4000rpm and then it goes away. it drives perfect and runs strong. Could there be something lose in the head?

 

Cam chain tensioner

 

i might have that same problem, but i just ignore it.
how long before it causes a catastrophy ?

 

Ya I do the same

 

mate i had the same prob on the same bike and what it actually was, was the engine mount bolt wasnt tight enough and the cage was vibrating on the frame!!! yep i felt like a dumb ****
