I have a 1999 CBR F4, and it is making a lil nois, sounds like valve train. I was told that the cam chain adjuster on the CBR's likes to go bad. I have priced the parts........... but i want to know if this is the real problem. The bike has 10,500 miles on it and i hear anywhere from 10K to 15k they go bad. Also what kind of valve train adjustments should i be looking to do.

Is there anyone on here that can do the work........... preferably a bike tech, or someone who has alot of reputable credit. And how much should i be looking to spend for parts and labor all together.

Thanks in advance!!
