Hi,

I have a 2001 F4. Recently its making some noise, if I rev it above 5000rpm. It feels like a resonant noise. I tried checking for any loose parts, but came up with nothing. I believe it is coming from the engine. Anybody has any idea?

thanks

 

It's your Cam Chain Tensioner Lifter (CCTL). On these bikes the CCTL have a tendency to become noisy after a while but it won't affect the bike mechanically. It's a fairly easy fix. Try doing a search and read up on it; highly discussed topic... LINK. < Web page's busted.

 

LOL, HUGE understatement. But, yeah. It's probably the CC smacking against the engine case. Here's the shortened versions of both sides of the debate:

Don't Fix It: Nobody has ever actualy experienced any sort of faliure due to a loose CCT, even after putting thousands of miles on it.

Fix It: It's not up to spec, thus, it's broken, thus, you should fix it. APE makes an amazing CCT that you can manually adjust whenever it gets loose, and it's only like $50.

 

Go to this web site and and there is a easy fix that Uncle Jeff has come up with.Here it is
CBRWorld.net - OEM CCT MODIFICATION PIC'S he seem to know what he is talking about he has wrote alot on the bb noise check it out and let me know what you think I am going to try it.
