The sound comes from the injectors..It isn't a mechanical sound.If you watching the needle in the gauge you will notice the fluctuation when you hear that noise.Perhaps a bad fuel or a clogged injector or something around there...Also a defective TPS can cause this symptom at idle.On the test this thing seems that it works fine but it doesn't works right..This sound has nothing to do with the CCT.

Thanks to everyone for your contributions. As mentioned I will start with CCT and plugs, plus pair removal while I am at it.

I hope to have a much better sounding video to post as a result.

Fingers crossed.

Great forum, great info.

Cheers,
Dave

I'd recommend you don't even run the engine, risk of skipping teeth and doing expensive damage.
Hi Rayzerman,

Got the side cover off. No slack in chain. Would you expect slack in every faulty CCT problem?

Will change the CCT anyway once parts arrive. The existing has no dots on top, blue nor green.

The engine turns fine with a socket wrench on the crank. No bad noises.

Thanks,
Dave

It may be that there is no slack noticable, a good sign. Agree change the CCT anyway since it has no dots (old original design). Be sure to ty-wrap the chain at the crankshaft end to prevent the chain from drooping down off the crank sprocket while you have no tension on the CCT when you release it. Also agree that the strange noise may be coming from elsewhere, but let's eliminate the CCT first.

Thanks Mate,

I feel better already knowing that the chain gear and timing seem to be in order. The manual says: \

Make sure that the timing chain tensioner
rod comes out of the timing chain tensioner
housing smoothly. If there is rough move-
ment, replace the timing chain tensioner.

So I may have a problem yet with the CCT that I just cant detect when it is under load. I guess I will see when I get it out.

In the back of my mind I am wondering if the clutch might need inspection. I saw a video of a guy yesterday taking the plates out and bathing them in oil then re-installing cause they were dry. What is this meant to improve in your opinion?

Regards,
Dave

The original CCT has a weak spring that got weaker with age. It may be smooth......


The clutch soak is meant to a) you'll clean the plates while you're in there, b) coat them with oil so the clutch releases smoothly, less drag when cold. The clutch does not get much oil normally. Do it once, should be good. It's optional, and usually only done if you're having clutch drag and associated shifting issues.

Before you take anything more off the bike I have a idea to help find the place the noise is coming from, do you have a long shanked screw driver in your kit, start the engine ,put the handle against your ear and the working end on different places on the engine until you find where the noise is loudest, then you can diagnose the problem better

Thanks Alan,
Waiting on the CCT at present, but once replaced I will use this method. Let's hope I don't have to though.

Hi Everyone,

So an update. Pair system removed and capped, new plugs with gaps checked, New CCT installed. NOISE IS STILL THERE as per original video.

When placing a screwdriver on the right hand side of engine and to my ear in various places, it sounds like clutch noise to me as the noise is loudest on the clutch housing cover. Any ideas what I am looking for that would make this kind of noise?

Cheers,
Dave

Also, it makes the noise at low revs on centre stand in 1st gear with clutch out. If it is clutch related then my understanding is that clutch plates would not make a noise in this condition. Perhaps then a clutch bearing????

Thanks,
Dave
