Well, the last few days my f4 has been making a strange noise. It sounds like a realy fast clicking noise and it goes up and down with engine revs. However it only does it sometimes. Does it both in gear and out of gear. Bike is running fine, and i haven't noticed any loss in power/stalling or anything of that nature. what could it be? it almost sounds like the chain, but it does it out of gear too.

how high does it go up to? any vibrations, feels like below the tank? if it's just a clicking but not much vibrations, it's likely an exhaust leak or chattering valves.

I personally wouldn't suspect the chain, or it wouldn't do it when it's not in gear. Maybe the dreaded cam chain tensioner needs replacement? When both of mine went, the was no noise when it was cold, but as she heated up, it deffinately got worse.

The camchain tensioner went on mine. It used to start with a heavy ticking and rattling (that didn't alter with engine speed) once the engine got warmed up . This didn't happen everytime, sometimes the ticking was less pronounced. if the ticking on your bike starts from cold and follows the engine revs like a fast clock when you blip your throttle then I don't think it's the CCT and I am not sure what it is because My bike still has that even after the CCT was changed. Many fireblades (injection models) seem to suffer with the cold ticking noise problems and most honda dealers haven't got a clue why. I would take it to a dealer in case it's the CCT. You are supposed to hear a slight rattle (noise) on the overrun when you blip the throttle. A trained mechanic should be able to listen for that if you can't.

yeah, it's sounding like the cct. It only does it warm, and only occasionally. How much re those bad boys to replace?

about 50$ for the part from most places.

bossturbo.com has a writeup on how to do it as well

I bought the aftermarket manual adjuster from the website link on this site. I went through 2 OEM CCT's in under 12K kilometers, So I got sick of paying $70 CAD for each CCT from Honda and went with the aftermarket manual adjuster for a few bucks more. Nice piece, works very well and can be adjusted without taking off the tank.

It's been about 1500 Kilometers since I have put on the manual adjuster and there is just a hint of chain sound, not a rattle but you can hear it vs. just hearing the whining of the cam gears. I figure I should get another 500KM's before adjustment. Semi-frequent adjustments are a small price to pay rather than the hastle and cost of replacing the cct. I like knowing that on the the highway, if she starts gettin' real noisey, I can pull over, pop the side cover off and adjust in about 15 minutes max. On 2000km's journey's (which I like to do on my F4) it's a nice option to have if you need to adjust it. But that's just me. I like to tinker with my bike, so it's fun too.

I would be worried to overtighten the thing. By how much do you turn the bolt to tighten it? or do you wind it on bit by bit and every time you listen to the noise and see if it's gone?

I adjust while the engine is running, just tight enough to make the sound go away and then add 1/8th turn and tighten the lock nut.

"I bought the aftermarket manual adjuster from the website link on this site." Which website? I have a noise problem too. More like a rattle, only when I'm on the throttle. The "rattle" speed increases and seems to get louder with throttle speed and goes away as soon as I let the throttle go. I Inspected the bike for something loose, didn't notice anything. Driving me nuts. I'll change the CCT just to try something.

or you can bust the OEM one and mod it so it functions like it should...it would benefit you to read up on other posts, especially in the TECH and F4I threads about modding the stock cctl...

also note that certain things also make a ticking sound...like exhaust leak and valve chatter...so you really need to know what you're listening for.

basically, you flare the pin on the OEM cctl that holds the tip on and the noise goes away, however, if the cctl is old, the spring inside loses its tensioner so you can wind the spring up like 2 turns max to give it more tension...also, the stock cctl acts as a manual one if you take off the bolt at the end of it and use a small flathead to turn it counter clockwise.
