Question about the ACCT. I have read many of the threads in the Vulcan Verses about the ACCT and feel I have a pretty good idea of how the ACCT works and how to repair or replace it . My question(s) are these. I have a 2002 Vulcan with 10,000 miles. Would an ACCT wear out at this time with only 10,000 miles. Does TOC still sell the replacement springs (I don't want to go with MCCT because I know myself and I wont adjust them enough) and do you feel it's better to replace the springs or the entire unit. Thanks for the help in advance. I am constantly on this forum and have learned a lot. It's a great forum. I just do not usually post questions.

I know what you mean. How often do you think you would need to make adjustments. I just dont want to have to be constantly messing with the tension, but if I had to adjust the tension as often as fixing springs well then...

Stull have the ACCTs in mine but have TOC manuals waiting for when the springs go. several folks that have made the switch have gone at least 10,000 miles on the MCCTs without an adjustment, IIRC.

I do not have the MCCTs myself, but from what I have read, it sounds like once they are adjusted you are good to go for the season. If you do need to fine tune them on the road it only requires two wrenches and a couple of minutes of your time. Much easier and quicker than rebuilding the ACCTs with the TOC HD springs, and a permanent fix too. Several members have reported the replacement springs for the ACCTs only worked for a short time before the cam chain noise started again. Many of them then switched to MCCTs, either TOC or home made modifications of the ACCT on the bike now.

You are all giving me good reason to think about the MCCT. SO how difficult is it to adjust the MCCT the first time. Is it just keep adkusting until the sound is gone or is there a specific setting/tension to go to?

Yes, basicly tighten until the cam chain noise stops, then back off a bit.
A bit of an art, but no specific setting. If you are intelligent and co-ordinated enough to ride the bike, I`m sure you can set the MCCT.:smiley_th

How to set the MCCTs:

I had the toc hd springs and my front broke, put my old one back in with an extra turn on the tension and been riding since. did not sound good at all when the spring broke 40 miles from home, had to keep high rpm's up the whole way home to keep from rattling so bad, put original in and I was good to go. gonna try the homemade one for the front with an extra housing I have!

How would you describe the cam chain noise, is it more of a raddle or a squeek. I have this low squeeking noise that is only present at a low idle of around 1000rpm, any ideas of what it could be.

It sounds like a rattle to almost a knock in the upper end. I have read that many other say it sounds like you are about to throw a rod. I am 99.99% sure it is not a rod so I assume it must be the ACCT. The sound is not so bad at startup, the gets worse after a few minutes and then quiets to a rattle sound after a while.

Do a search for the Grambo Trick and try it. If the noise goes away, it's the ACCT.
