CCT Updated again?

[WJBertrand]

I noticed when perusing some parts fiches that Yamaha has fitted a new PN CCT starting with the 2017 model. Looking at other year models, this latest part number supersedes both the original Gen 1 and later Gen 2 CCT part numbers with yet another one. Anyone know what they have changed on the CCT this time?

 

[2daMax]

Can't answer but glad Yamaha is still trying to improve the design. Now, waiting for early adopters to let us know...

why not just go with a manual CCT and forget it.
When I rebuilt the top end on my 2012, the manual cct didn't even budge after 40k km...

Usually if there is a major change the first three letters/numbers will change like it did between 13 & 14 models. By changing the 00 to 01 that could be something as simple as a different color. Take 2BS-12210-XX-XX. The 2BS tells you it's a 14 model part, the 12210 means it's a CCT and the XX-XX usually means a minor change such as color. Someone will have to compare the two in order to know for sure.

Thanks, I've also heard that the same design might be sourced from a different supplier and given a p/n change to keep track.

The K&N filter person I spoke with was REALLY frustrated that the company didn't do this, but it was after they found their new supplier had changed oil filter baseplates from concave to convex.

Based on my experience working for companies that manufacture items, the main reason for a new part is cost reduction, not an improved design. A new part from Yamaha doesn't necessarily mean it's a better part.

Anyone have any news on this new part? I've already replaced the original '12 tensioner with a '14, and now 65,000 miles later the '14 tensioner is getting a bit noisy. That's only 10,000 miles less than the mileage on the original tensioner when it failed. So wondering if it's time to replace again - either with the '17 part or a manual CCT. If the '17 part is improved again, then I'd rather go with that than the manual...

Sorry for the delayed response, but I would think that if one has an active YES policy, fitting an aftermarket tensioner would disavow Yamaha of any warranty responsibility should you have any kind of problem with the valve train or even the engine later. Personally I will stick with OEM bits while YES is in effect.

I would make sure Yamaha never saw a manual CCT on the bike. They put a junk one on and I would have no bad feelings about running a better CCT and not telling them.

This made me chuckle.
With 130,000 miles on four continents while loaded for living off the bike, I doubt warranty is the something that DCStrom is concerned about. He's one of our top testers in seeing how reliable the bike can be under long term and adverse circumstances.
And a nice guy.

Ha! Yes, in that case no concerns. My case however is different.

Not trying to start a debate or criticize your choices but, just out of curiosity, what brand, weight, and frequency do you change your engine oil? :

You can ask , but I don't think it has much to do with tensioner issues. As far as I've seen, everyone that has has failures (with the early tensioner) has been in the 60-80,000 mile range. Maybe oils and change intervals effect that a little bit, but the fact is it will fail at higher mileage no matter what your routine.

I try to run 10-40 semi-synth motorcycle oil most of the time, prefer Motul or Yamalube if I have a choice. There are times when I have to use what I can get - like in Iran where motorcycle-specific oils are impossible to find. Oil changes are dictated by wnen I've used my spare half-liter of oil. I buy 4 litres for an oil change, and with the leftovers top up when oil level is at the low mark, roughly 2000-2500 miles. When it needs topping up the second time, I change. That could be as little as 3500 miles if I've been doing a lot of higher-speed riding, or as much as 5000 miles. Oil useage has changed very little since new, and I'm at 138,000 miles now.

I'm not aware of a bike with an automatic CCT that doesn't have issues with them. It's the nature of the beast. MY other bikes have manual tensioners installed or have them waiting for installation.

OK my great Yamaha dealer in Athens, Greece listened to my tensioner the other day, agreed that it was a bit noisier than it ought to be. We decided to replace, with the '17 tensioner. Now all quiet again. One less thing to worry about!

 

[Checkswrecks]

WIN!

I went 150,000+ miles on my Honda ST1300 which has two automatic CCTs Never an issue. Further, I can recall no CCT related issues reported on any of the numerous ST/Pan forums at all. So now you are aware of at least one bike!

169,000 mile on my 2004 ST1300 - rear ended 4 years ago - no valve adjustments required no CCT issues

My Kawasaki Voyager currently has 668,000 kms on it, 403k on the original engine. This is a big SOHC 4 valve per cylinder v-twin with 2 automatic cam chain tensioners and the chains & tensioners are original and trouble free. The tensioners are actually buried inside the crankcase, hydraulic applied with a ratchet to prevent slack. Completely trouble free engines, oil change every 10k and spark plugs at 100k, nothing else.
I have a 3rd engine ready to install at 800k, just for peace of mind.
