|VN750_DawgsFan||Same as what others have said. Only answer I can give is getting the MCCT's. I did the TOC rebuild on my ACCT's and about after 2000 miles, the ticking came right back. So I just forked over the cash for the MCCT's and haven't had a problem since.|

HMHO, the main issue with the ACCT's is the spring located ABOVE the ACCT under the chrome bolt. This spring is the spring that applies pressure to the cam chain guide to keep it firmly in place.
see part #92081
The ACCT's job is to keep the guide from backing out when the chain wears and stretches. Think about it people, do you really think that tiny weak spring in the ACCT can provide enough tension to manage the cam chain? the work is done by the spring under the chrome bolt cover! When that weakens, the ACCT can't do it's job.
Here's your solution: Remove the chrome bolt cover, retrieve the spring, stretch the spring out about 3/8" longer to give it more tension OR go buy a new spring. The top of the motor gets hot and if the spring weakens, the ACCT can't do it's job by acting as a stiff rod, not as a tightener.
I lubed my ACCT with grease - that helped a lot - thinking like most people on this site that the ACCT is weak but came to realize there is so much pressure keeping that chain in place that there is no way the ACCT is the only problem with the design.
I stretched my top spring months ago when slight ticking started and it's been sweetly quiet since.
If you do this, please report back the results you achieved.

If the bike sets even with new oil in it it still loses viscosity over time. It is smart to change the oil and any other fluid when buying a used bike no matter if they say it is fresh. Very easy and inexpensive to ensure good lubrication. Then you know what is in it.

|slimvulcanrider||changing to a full synthetic oil will help some. but changing to the MCCT's will fix the problem guaranteed if it is a Cam Chain Noise.|

When I spun the ACCTs they spun back nice and crisply on both sides. The springs didn't seem fatigued. When I applied the counterclockwise torque to them, I was fairly cautious with how much I applied because I do not know how much you can get away with.
If MCCTs are my only next hope, that may have to wait a while due to $$$. And, if I do get MCCTs, is that almost a guarantee of quieting the noise?
BTW, it's a 2004 with 5500 miles.

|weh44att||Have you installed new springs at all on the bike, or are they the original when you bought the bike. The springs do go bad sometimes in a very short time. Is this an older bike, if it is the MCCT's maybe the only why to go to get rid of the noise. You do not want to try and tap the mechanism, or levers inside of the engine to try and rid yourself of the noise.|
