The powers that be of this forum will probably be unhappy with me for further pursuit of the ACCT to MCCT mod again. But I have never really been convinced that the ACCT to MCCT mod is the right thing to do.
I talked to a Kawasaki Service manager from a dealership that shall remain nameless. And he stated (after much consulting with his mechanics) without a doubt that the only problem with the ACCT is that the chains get a little noisy. And that they simply replace the entire ACCT assemblies. He also stated emphatically that no VN-750 has ever failed to bring a rider back to the barn. A'HEM!!!!
I had previously asked if anyone had ever replaced entire ACCT assemblies, but I guess that I failed to make it absolutely clear as to what the question clearly entailed. What I really meant was, has anyone, or any number VN-750 owners replaced the entire ACCT assemblies? And if so, did that cure the problem? And how long did the fix go before failing again, if ever?
If any of you have opinions that do not relate directly to my inquiry, kindly keep them to yourselves! We all know about unrelated opinions, now don't we?

Like I said in your other thread:
If someone did replace the whole assembly (with new ACCTS) it would work as intended for sure. Now as for how long...that's a crap shoot. It depends on several factors but there are many here who still have the original ACCTS that haven't had any issues.

Geezy, Yes people have changed out the complete ACCT's with brand new factory replacement ACCT's, only to have them fail again a couple years later. The owner of TOC Manufacturing used to be a member on here back in the day and tried to come up with ways to fix the week problem. First he built the heavy duty springs, which helped but didn't cure the cam chain clatter. He then realized that a manual set like off of a CB750 would do the trick, but they didn't fit, so he machined his own.

I have been on here since 2008, I have seen people try everything to fix the ACCT problem, and only two solutions have ever been presented that cured it... Making your own MCCT, or buying the TOC MCCT.

I appreciate all of your input, but have yet to hear from as many as I can who have actually replaced their ACCT's with factory ACCT's and what the results were. Maybe, just maybe, the factory has updated their ACCT assemblies that work properly and last like good Cam Chain tensioners should.

I converted mine before they needed to be replaced. I get what you're after, you want the part to work the way it's supposed to... I think if you asked everyone here, they'd probably agree with you on it (I certainly would). Based on what I've read in all of these threads, there is an engineering flaw that they never addressed and some folks with a little imagination came up with a clever fix.

It should be noted....and has not been yet that Ive seen, is that the upper cam chain itself will stretch after awhile...this will make the ACCTs useless when the chain is stretched almost to its limits....now...using MCCTs on severly worn chains is lookin for a tow eventually, although it will get one thru for another 2000 miles or so......

From what Ive heard/read, the factory DID make some changes to the stock ACCTs....unconfirmed though...but after say, the 3rd ACCT change, one would probably need new upper chains anyway...
I went homemade MCCT to save for 2 new chains, lol...
