When I go above 5000 rmp (no matter which gear Im in) my bike makes a really loud noise(I thought its from the engine), its not knocking (althought thats another problem that I have when its cold only) but its sounds mean. Somebody told me that it may be just the muffler.What do you guy think. This is my first season and first bike. Its not in a bad shape but I already had few incidents with it. I decided that Im gonna keep the bike anyway, and try to fix things up (winter project). Do you guys have any tips what should I work on/ look in to especially.

Thanks,
Trish

 

It's the CCTL (Cam Chain Tensioner Lifter). Do a search on the forum. You can either replace it or live with it.

 

like Ehonda said, CCT, I'd replace it before living with it... live with it too long and your cam chain will slip a tooth and blow your top end to bits.

Ape sells the manual cam chain tensioner for about $50, it's an easy install and can save you lots of $ in the long run. Unlike the OEM CCT, the manual CCT will never fail if installed and set up properly.

 

It also won't automatically adjust as the chain stretches due to time and/or heat. And, how can you guys possibly diagnose CCTL with "a loud noise." For all we know, it could be a backfire or a freakin fart.

 

I thought the same thing, could be any number of things causing it.

 

From what I see all the f2 have similar problems. So is a CCT something come on, like the retrifier burning out in almost all F2's.

 

The CCTL wasn't really a problem until the F4i, then everyone jumped on the CCTL bandwagon.
Plus, I'm sure not "almost all" rectifiers burned out. If so, I have one of the valuable rare unburned ones!

Maybe if you could describe the noise better and walk around your bike and try to give a general location of the noise, we might be able to diagnose it better.

 

I am pretty sure that the f4i wasnt the start of the cct problems... the cct is a very common issue with f2's and many other bikes...

 

CCT issues were apparent in the original CBR hurricanes... F1's, F2's, F3's F4's and F4i's.... As well as regulator/rectifier issues.

My bike is a rebuild because it caught fire due to electrical issues...

 

Count me in as one of those with a replacement R/R. The previous owner must have done it at least a few times because he actually installed a tube running from the front of the bike, through the frame so that air would blow on the R/R.
