It cracks up b/n 4800-5000 rpm not real loud but noticable, just sounds like hell.
I have read about the cctl's causing problems/ noises but the guy I bought the bike off of says he had a new one put in and is convinced that thats not it. Could it be coming from one of the valves?
I'm taking it to the Honda dealer this weekend, just thought I'd see if anyone had any input or experiences.
I don't have the money to have any engine work done so basically I 'm just trying to figure out if it's safe to ride or if I should park it?

 

CCT is my bet. That's the exact RPM range that mine made noise. My SV's cam chain tensioners also make a little noise at those rpms.

The bike is fine. You can ride it, it's just annoying.

Park it.

 

my cct made noise right around that rpm
they go bad on f4is pretty easily
I rode mine for about 5k with that noise, no problems

<U>Park it</U>. Why?
b/c when you owned your 1995 Honda CBR600 F3, you had a similar problem ? or know someone who has and you know that it will lead to greater problems? or b/c you are a honda mechanic or otherwise very knowledgable about F4i's and you can diagnose the problem for me so I don't have to waste my time and money going to the dealership to have their mechanic look at it? if this is the case plz let me know ?
just wondering why you say park it ? Thanks

 

Thanks for the replys.

I know they go bad, and I know there are thousands of people that can vouch for riding for 10k+ miles w/ it making this noise but unless the guy that I bought the bike from is full of **** then the cct has been replaced and that is not the problem. of course he has no receipt to prove this either.
the bike has 15k on it so it could possibly have been making this noise for 10k+. I am still riding the bike trying to tell myself that it is just an annoying sound and to ignore it but then I take into consideration that I don't really know if it is the cct and if anything has indeed been replaced or how many miles it has been riden like this or how the scenario plays out if it does decide to go ?
will it jump a tooth and lock the engine up at 60+ mph sending me sailing into anything but soft cushion ?
or will the engine just stop running and I will apply the brakes and slow into a gentle stop ?

Did he install it himself? Did he use the OEM cam chain tensioner or did he use an aftermarket one, such as APE's manual CCT? Were they new parts he used to replace the CCT with?

If he merely pulled out the old one and put in the new one, the cam chain may have jumped off the gears so that there is just barely enough pressure holding the chain.

Because you're trying to diagnose a problem that you don't understand by describing a noise you've never heard before on the internet... and you don't have the money to fix it if you're wrong about what it is.

It sounds like you've already decided that you think it's the CCT, though.

Yea, he said he replaced it w/ an oem one but it is safe to say that I know none of this for a fact and probly should leave it to the honda mechanic to diagnose and fix.
I guess I was just looking for suggestions or other possibilities of things that it could be, but from the symptoms I have descibed, the general consensus seems to be that it is more than likely the cct.
He mentioned that it could be the valve "seat or bucket" but I don't know if that makes sense b/c I know nothing about it. but that is why I asked if it could have anything to do w/ the valves?
Thanks

 

Does this conversation remind everybody of the boxing movie when the boxer gets a new trainer and he says "well who the hell are you? What have you done?" and the trainer says "you first"?

Seriously - saying it's not likely because you don't understand it is out and out dumb. We're not going to be able to diagnose a broken-something noise coming out of your engine block with several hundred moving parts and bearings just by a description of a 'cracked up' noise that 'sounds like hell.' If you're freaking broke and you don't know what it is then leave it the heck alone until somebody that does know what it is can look at it... otherwise you're probably up for a costly repair. Hell, even if it IS the CCT if it's failed then there's a chance that you could send a piston into a valve and do your motor in for good.

Park. It.

- I was not questioning anyones intelligence or knowledge, I will be the first to admit that probly everyone in this formum knows twice as much as I do about motorcycles

"Seriously - saying it's not likely because you don't understand it is out and out dumb."
-If you can quote my post that I stated that, then please enlighten me.

"We're not going to be able to diagnose a broken-something noise coming out of your engine block with several hundred moving parts and bearings just by a description of a 'cracked up' noise that 'sounds like hell.'"
-I didn't ask for a diagnosis, if you read closely in the original post I only asked for input and experiences. So since your input sucked and you stated no relative experience your posts were about a 0/10 on the helpful scale.

I was looking for something a little more helpful than just "Park it."
I already had an appointment w/ the honda mechanic, just thought I'd see if anyone on here had any similar problems and found out it was something besides the CCT or if there was something simple I could check before being charged $60 an hour to have the mechanic look at it.

to useless posts

After visiting the honda shop, the mechanic obviously could not give me a 100% accurate diagnosis from just listening to it but said that it definately needs the valves checked and probly adjusted and he would also check the CCT

How much has anyone paid for a valve adjustment? and is this common for a bike w/ 15k mile ?

Thanks.

Do you have an owners manual? Service intervals are in there.... valve check and adjustment (if needed) at 16k miles, IIRC.

 

No, I didn't get a manual w/ the bike but I will download one. I didn't think to look there.
Thanks

 

from my personal experience my F4i's CCT went bad at 8k miles. I had it replaced by a reputable shop with a new OEM CCT that was supposedly better. That one started to fail at about 11000 miles. I never did any track days on the bike.
Honda's CCTs just fail, it's life. And it's not really that they fail in the sense that they stop doing their job. The threads on the plunger inside the CCT start to wear and loosen making it rattle. The spring is still functional and it still applies pressure to the cam chain, but it makes noise. I know the Suzuki SV CCTs use a ratcheting system rather than a threaded thing, and some R1s use a hydraulic CCT. Honda uses a threaded plunger with spring tension behind it, and it fails.
You're ok to ride it most likely.
If you're going to replace it i suggest getting the APE manual tensioner, that way you still have to deal with the CCT at the same mileage intervals, but you'll just have to adjust the APE rather than replacing the stock one.
I think either product is under 100 bucks, and with some tools you can do it yourself.

 

FWIW, the CCT was rattling on my F3 after I bought it @ 22k miles - I replaced it, then when I sold the bike at 35k it was making noise again. At 12k miles, the CCT on my F4i is not making noise, but if it does I'll replace it with OEM - its $50-60, and I like OEM parts - a 10-12k replacement interval is not that bad.

 

I might consider replacing the CCT before I take it to Honda for the valve adjustment but I might just have them do the CCT also.

I found this DIY http://www.bossturbo.com/cbr/howto_cct.shtml on an F4 but I'm sure its the same on F4i's though

Thanks
