That horrifying "clicking" noise

12197 Views 73 Replies 9 Participants Last post by  Craig4722
I have just noticed that when my bike has a cold start (either when it sits for a day or two, or when I start her at night), that if I give it a few revs, I hear a very faint cicking that is syncronized with the engine RPM (hope that makes sense). This occurs in the 3,000-6,000 RPM range (thats at least when I hear it). After the bike is all warmed up to about 150+ degrees, I rev it up and the clicking noise seems to go away. I rode it a few days ago with a 48 hour "rest" in between rides, and noticed it then. Also noticed it tonight when it was sitting at the little ladies house all night after I rode it today. I had to actually use the choke for the first time, or the bike would crap out. Every stop sign on the way home I gave it a rev or two to see if it made the noise. Realisticly, I dont think it was. But by then my mind started playing tricks on me. When I got home and rode in the complex parking lot, I cruised in at 3-6k RPM range and heard nothing. I have never before heard this noise, until I have had a few true cold starts. Is this something I should be worried about? :help:

Its not a tough job. Just don't expect it to be quick.
:iagree: If I were to do it myself, I would be VERY VERY careful and meticulous. Weekend project for sure.

Im not even sure If I want to install it myself. I dont know how much or not much tension a cam chain needs etc, etc.

That info should be in your manual.

whats a manual? :lol:

Didnt get one with the bike.....I should order a Haynes manual soon. I can always look up the specs for the bike on the web. but this is free, and will work for now.

just finished a ride. Not the best ride ever. I was slowly cruising in 1st gear and noticed when it got to a certain RPM, the front part of the bike would rattle like crazy, it made my legs numb for a second. I was at a red light. Once it turned green I monitored my RPM and at 7-9k, it started that rattling again, bad. Anything below that RPM is fine and dandy. I think the CCT is gone bad real fast. I probably should expedite my CCT issue and buy a new one quick. The hydraulic CCT is about $100. The manual one is about half that. Looks like the bike will be garaged for a while until I get this fixed :yesnod:
digital pics will help too...

But whenever I start a project like that I start in the morning or lunch time and make sure I have nothing else planned for the day... that's best...take your time and do it right! Plus don't forget your muffin pan...



As funny as it may be it works great!

Now that sounds more like an ignition problem, like a bad coil, plug or plug wire. When the CCT goes bad or the chain stretches, the cam timing is retarded. Runs great at high rpm, but not at idle and low rpm. Could also be a loose or broken motor mount. I think it needs some more testing. And some muffins would be nice too.

:iagree: You shouldn't get that bad of a rattle from even a bad cam chain or CCT.

Don't forget the muffins. :lol:

what are some other symptoms when you say the cam timing is retarded? I noticed today that when I gave the throttle a squeeze it was slightly delayed (this is from I would say 15-30MPH range). I figure the vibration would progress and not start all at once if it was a motor mount, but I will also check that too. As far as ignition goes, what are other symptoms? I might have over exaggerated when I was describing the vibration, but it was quite noticable. Legs were tingly. Oh and I was given a bunch of those connectable bins so I use those instead of the muffin pan :D
maybe I have a whole slew of problems...GREAT!!! :cursin:
I would fix the CCT first. Give every thing a good looking over while doing the job.

Yea but now I am all nervous/ticked off that it might be more problems...oh well. I will do another analysis when I ride home tonight. Then I will prop her up on the stand and order my CCT.

When my CBR had no high-end power, I thought it was the carbs. After cleaning everything in the float chamber and vacuum chamber, the bike ran the same. I pulled a spark plug and had a good spark. I pulled each spark plug and the color was perfect.

I hooked up my old timing light to #1 cylinder and aimed it at the timing mark. It was on the top dead center mark, but it should have been on the "F" mark. I reved the engine and the mark didn't move. Needed a new pulse generator. After $50 and one week wait for the part, it worked perfect.

So nowadays, I check the ignition first, then the carbs. The Honda shop manual has all the resistance values for checking everything in the ignition system. Just need a digital voltmeter ($20 from Sears). BTW, it looks pretty simple to replace your CCT. Mine is in the engine, under the exhaust cam.

I plan to replace that first. I will run some tests and see if any other problems continue. If the other problems proceed, I will bring it into a shop and get taken for all my money again :bash: For all I know it could be a loose fairing or something causing the other stuff.

:luck: It can be a PITA sometimes to diagnose a problem.

thanks, it looks like I might need some luck. I will give you guys an update if I notice anything different on the ride home tonight,.

Okay so I just got home. The vibrating I was talking about at 9k, not as bad as I thought originally, and the legs get tingly but barely. My mind must have been more concentrated on the road, and that just startled me. This only occurs at 9k. You go over, its stops. I guess its that certain RPM that sets off something. Usually the bike vibrates a little when you get around that RPM range a little, (is that normal?) So I really dont know whats up with that.

okay now on to CCT. I heard the noise pretty much the first half of the ride home at low rpm. Still very faint, but noticable. I also heard it a little while in the driveway. There should be no doubt in my mind its the CCT now, according your guys' help and info. Bike bandit.com has the oem part for like $85. Ebay has nothing new except the manual ones.

Yeah Snade...but I think you can tell by everybody here's expierence... you don't want the crap OE stuff... get the manual ones... better for the longer life of the bike...

I would have no problem buying the manual one and installing it. Its the setup part that scares me. What If i put too much or to little tension on the chain? etc etc.
Just purchased the APE manual CCT. Talked to seller and he says it comes with install and setup instructions so I shouldnt have a problem. Now I am all anxious to see if it comes by friday!!!


:D :D :D
