CCT Advice Please

[Tony Down Under]

My 2011 S10 has 45,000 km's on it and cold starts are becoming progressively noisy. I'm just about to do the valve clearances and will replace the CCT while I'm at it. Is the conventional wisdom regarding CCT replacement leaning towards a manual CCT over improved OEM CCT? OEM CCT in Oz is close to $300. I can pick up an American made MCCT for less than $100, which includes freight. Also, for those that have MCCT's how often have you had to adjust tension after initial install?

Thanks in advance,

Tony

I had a new 2014 upgrade CCT ready to install into a 2012 bike, but ended up trading for a 2016. But I was divided about the MCCT and OEM CCT, and I think a lot of those that were past their warranty periods did go the MCCT route, with very few issues if any, BUT, the chain tensioning on the cam procedure must be adhered to, or you will have 'chain jumping' issues and timing problems. But the success and satisfaction rate is very high and once done, almost forgotten.

I like the MCCT, I suggest not buying the "EBay" type.

People are really divided on manual vs the new OEM style. You'll find major proponents for both.
If yours has been rattling a long time and being 6+ years old, you might consider replacing the chain. They aren't that expensive and you'll already be in there.

I think it comes down to if a person is willing to adjust the MCCT. If you are more on the mechanical ability side, probably. If you are not, or just really like the put in and forget crowd, no. For me, how much is too much or not enough adjustment drove me to the updated factory one for my '13. Have not heard of a failure on the gen1 bikes with the updated CCT. But the MCCT is most likely the most accurate , and with the OP doing the valve check himself, I would say get the MCCT.

Thanks for your advice everyone, it was much appreciated. I'm now leaning strongly towards a good quality MCCT.

I fitted an APE MCCT to my 2013 S10. Fairly simple job but you must keep tension on the chain while changing it.
I haven't done a lot of miles since but so far so good.

This is the pro version. It comes with a gasket and has a finer thread than the the standard one.

Has there ever been a documented failure of the upgraded OEM CCT? I haven't heard of one. I'm not afraid of MCCTs as I used them on race bikes for many years, but IMO using one on the Tenere is answering a question that nobody is asking. That being, 'what can I do to upgrade the failure-prone upgraded OEM CCT?'

(it isn't prone to failure)

I don't think there has been a reported failure of the upgraded OEM.

And I didn't choose to go to the mcct because I thought the upgraded oem would fail. How could I know? It had just become an option by Yamaha.
However, what you call "answering a question nobody is asking", I call "better safe than sorry", at the time.

Obviously there is now a bit of history on the upgraded design. But remember, many of us were dealing with the very first discovered serious vulnerability of our PDP Teneres, and the racket that a poorly functioning cct created was intimidating. It's an unexpected and disconcerting clatter.

If I had to guess by all logic, I would bet most if not all manual CCT are adjusted too tight, so stress on chain, ect is high and wear is higher than using the factory tensioner.

 

[snakebitten]

RonH,

Yes, the mcct could be considered a farkle if you really really stretch the definition.
(And I (we) know your anti-farkle stance)
But why would you come to such a conclusion?

So what are your feelings about all the bikes that actually come OEM with mcct? For decades, by the way.

I'm a bit tickled that the Manual Cam Chain Tensioner is considered such a sophisticated device to manage.
It is a screw! Nothing could be more basic.
You can hear if it's too loose.
You can hear if it's too tight.

I should be asleep. Why did I wake the tablet? Lol

Notice I said "a quesiton nobidy IS asking" as opposed to "WAS asking." Obviously back at that time if there was no credible replacement from the factory, alternatives were necessary.

A question that I have is that if the CCT adjusts to get the right chain tension (because the chain stretches due to wear), would it be true to say that if I keep the old CCT and just change the Chain, all things will be normal again?

If the cost of the chain is cheaper than the CCT, then changing chain would be more cost effective. Like to hear other perspective. Thanks.

The 2012 CCT failures were either due to reduced oil pressure or weakened spring to keep tension on the chain. So no, changing the chain would not solve a CCT failure, the chains do not fail, the tension comes off the chain and that is related to the CCT. I cannot believe the cost of a chain and labour involve would be cheaper than a new CCT?

iTS time for a new tensioner for me.Has been rattlin on start up this year,but today on startup it was VERY loud.Going to try to get my dealer to fix under y.e.s. .If not, a call to jaxon is next.2012 with 45k.

If they don't you should find another dealer. That is a no brainer if your bike is extra noisy at startup.

 

[jimmy z]

Problem is silver,it doesn't do it at start up every time.
