I got a clatter

[tomatocity]

Tomatocity, you've probably said before, but was that the 48,000 mile valve check that was about to be done? If so, that would be the earliest failure I've heard of.

It was the 52,200 valve adjustment. I had just changed oil and had zero miles on that change.

The more I think about the cct failure, I wish Yamaha would have replaced the complete engine/transmission/output. I would have had it back in a month.

Same here, had just changed the oil. First start after that, SNAP. I have written before that I believe the dry sump engine lacks oil pressure for a longer moment after an oil change and that this likely initiated the failure. Had I just ridden it down to the dealer with dirty oil, it probably would have been fine. Bitch of a lesson there.

IOW, if you suspect your CCT clatter to be excessive, take it to the dealer BEFORE you change the oil.

Wonder if Yamaha is listening. I say this proactively. A Technical Service Bulletin or notice to dealerships could save Yamaha a lot of money (in the long run).

Bend over Bobs as you say , try,s to follow the line . But over a little time I convened them I know something about engines, and they went a head changed mine early on . Jason was on the phone with Yamaha trying to get them to under stand , I think they new what was going on but are trying to save money until they had to . He did give me a direct line to a guy at Yamaha to talk to . I got over 20k on the new one and it,s fine .

Thank you all for your quick and experienced feedback! I will keep my ears tuned to the rattle, and roll the dice (a bit, it seems), until the scheduled valve check… unless the start-up clatter becomes prolonged. I had been hesitant to ride after reading the issues some have had here on the forum, but now know I can relax a bit and "stop chasing noises" as someone put it.

It's good to be informed though.


YZ, thank you for the generous offer to, "listen to my clatter." That's very kind of you.


Now, I think I'll go for a ride!

Just ride, some bikes (not just the Tenere) have that noise, some for far longer than one would think is necessary but they do and get on just fine.

It is easy to get yourself worked into a tizzy, but best not to.

I would take the advice of many others and just deal with it at the 24k adjustment. IF it is not paid for just try to work something out maybe on parts etc with the dealership.

Mechanics get tired of the "I heard it on the net" nonsense, not saying there are not some credible people, just saying lots who are not as well. Since you are not Mechanically inclined it does make it a bit harder to weed out the two.

Having just got my S10, I noticed the engine is a fairly loud clunking affair. Is the timing chain noise something I won't have to wonder about? Like something that is easy to recognize over the "box of spanners clunking down a stairway" noise (as someone said in another thread).

What year is your Tenere?

You should be concerned with any "fairly loud clunking affair". Take it to the dealer and document your concerns. This will help when it breaks.

Clunky is never good ???

I have a '12 with Y.E.S. warranty.....mentioned to my local dealer that its noisy on cold starts....they called Yamaha and was given approval to swap out CCT with updated part number....Yamaha gives them 2.5 hrs to swap it, but the job took 8 hrs...(remove valve cover to tie cam chain to sprockets) They lost their a$$, had to eat 5.5 hrs labor. Shop owner said he will never do another CCT upgrade, loses too much money..Yamaha repair manual sez you must tie chain to cams, no other technique is acceptable. I've heard of guys tying the chain down by the lower sprocket, but I fail to see how to get a TY-wrap in there to tighten it up. Maybe sneak a piece of safety wire there possibly.

This would have been a good time to negotiate a valve adjustment.

Surely a competent mechanic is not going to take 8 hours to change a CCT? Maybe it would, if it's the first time they have been inside a Super Tenere engine, they are having to learn every trick from scratch... but that's all part of the learning process isn't it? Next one will be easier... oh that's right, there won't BE a next one for this dealer, so he really did waste 5.5 hours labour.

Mine is a '12. Maybe clunking is not the right word. Clatter is more correct. I named it chatterbox ( just like a woman, it never stops talking to you as soon as you turn it on).
I took it to the dealer and the service guy listened to it and said just ride it.
He did tell me how to replace the tensioner the easy way - taking it straight out of the side of the block. I had already read the thread on how one person in here did it but let him explain it without any noob input.

Question- if it can be taken out without getting into the engine, why don't we do it and be done with it? ( He told me the chain wouldn't slip because it still has tension on it.)

 

[tomatocity]

Is your '12 under extended warranty? If so copy some of the reported authorized warranty replacements/upgrades and take it to him. Also copy the CCT failure cases and show them to him. Now send those cases to Yamaha Warranty Y.E.S. and let them know you have been denied replacement/upgrade by the dealership service department. If you present this nicely and completely someone will be contacting you about bringing your Tenere to a dealership.

CCT Failure: My Tenere has been in the shop for more than three months (supposed to get it back this week). Another forum members was four months. The parts list is approximately $5,000. Not sure what the head rebuild is but not cheap. The labor has to be a ton. Me being without my Tenere... PRICELESS !!!

The good thing was I put my KLR back on the road and have been enjoying sport version of the Tenere.

He is incorrect. It can jump teeth if the chain is not secured in some manner. It won't happen all the time, but it can happen. I personally saw that happen to a local friend who is on this forum. He changed his cct on his 12 model and when he tried to start it up, he heard what he described as an expensive clunking sound. $1200 later with 2 new valves installed by the dealer, it was running again.

Your tech is a little off. The cams are under valve spring load in opposite directions no matter where things come to rest. Take the preload of the tensioner away and that rotational tension will force the chain up and over the slope of the cam teeth. Usually once it's free, it will click over two teeth at TDC. Two teeth is about the number of degrees difference in the cams going to neutral. That's the same tension you have to deal with when doing a valve clearance adjustment when you have to lift the cams off.
With the side cover off you can apply enough tension to keep the teeth and the chain engaged enough to prevent a jump. That one shop doing it exactly by the book... I'd think flat rate techs would have all the short cuts down.

This, I cannot Imagine anyone used to turning wrenches could be stumped by any modern engine.

Thanks for the replies, guys! I'm pretty much a worry wart when it comes to engines (I have had more than 1 catastrophic failure). I'm really thinking it can wait until I have the valves adjusted/checked. I will definitely have the '14 cct put in at that point.

My Tenere CCT failure happened one week before the scheduled valve adjustment and warranty CCT upgrade.

Did you have any warning?

Its why I took it to the dealer. I didn't know how this engine is supposed to sound. The dealer made me feel somewhat better, but I still think I'll have the valve check done before the recommended miles. I'm going to trust the dealer and take a trip to pick up some Pelican cases next Sun and Mon.
It'll be about 600 mile round trip.
If it fails, it fails. Can't live in fear.....
