Who will be changing there chain tensioner to the 14' during valve adjustment ?

[Koinz]

Well your dealer isn't being 100% honest.

If your valves are "ok", than they are somewhat correct in that the cam chain tensioner would not be touched. However a bunch of the labor to move the gas tank and other parts to access the area is common.

If your valves need adjustment, the cam chain tensioner must be removed/reinstalled anyways.

Thanks for the info.

I think it's a case of ignorance than dishonesty. They've never done a valve-clearance check on an S10 and are pretty unfamiliar with the engine as it's not a common bike here in Japan. He was looking at some diagrams online but likely missed that. I will let him know, any additional details/pics/service manual reference that anyone can provide would be welcome

In my opinion, that's a BS excuse. EVERY chain driven cam motor in any motorcycle, regardless of brand, works like this.

Clearly they are pretty unfamiliar with motorcycles in general...I'd be wary.

This is one of Yamaha's flagship shops in its dealer network.

I didn't know you're a regular over here. We should get together for a ride sometime. ::008::

Ha! If I ever make it over there, I'll look you up.

Either way, if a dealer isn't "familiar" with the STANDARD method of cam drive used by just about EVERY Yamaha...and they claim to be a "flagship" dealer...I'm scared and I would be very leery about leaving them my bike to do work.

Yeah I get your point. I only talked with the manager not a mechanic, so I'll double-check with them about it and there's also one other dealer I can check with. Does the service manual cover this job? It'd be helpful if I can show it to them.

I also want to see if I can get it changed under warranty, does anyone have any Yamaha documentation approving the coverage?

At 52,800 my 2012 NEEDED a valve adjustment. Thanks to this forum I knew about the updated CCT p/n and preemptively changed it out. Lights off much quicker, quiets down right away, and runs smoother under load (valve adj).

Of course you will find this procedure in the service manual.

Just looked through the Service manual at the valve clearance check procedure. Maybe I missed it but I didn't see where it mentions the cam chain tensioner. I do see where it says to remove the timing chain and cams if the clearance needs to be adjusted on page 3-6. I guess this is where the camchain tensioner is removed?

The CHECK won't require any CCT involvement, only when an actual adjustment is necessary if it's like my prev bikes - haven't done one on an S10 yet.

Yeah, I just edited my post to note the page that the service manual says to remove the timing chain.

In any case, even if a valve clearance adjustment isn't needed, is it a simple step to change the CCT while everything's apart to measure the clearances?

Looks like my local dealer is replacing mine under my YES warranty. They listened to it and deemed it sounded too loud. I requested they listen to it while it was getting the headlight sub-harness warrenty. 22K miles.

Exactly. It would add a little labor since the side cover has to come off to release the CCT, but realistically it wouldn't add but 15 mins to a "check" procedure since the tank and everything would be removed already for access.

I think you nailed it ac. But a lot of techs are used to only needing to check [/] the valves instead of re-shim them. Re-shim means pulling the cams, as you know, so the CCT is trivial at that point.

Which side cover is that?

Clutch. It's covered in the service manual. I got by without changing the gasket once.

You need to remove the clutch cover to access the cam chain tensioner?

Didn't you say you just looked through the service manual? It's all in there.

You have to remove the clutch cover to smack the cam chain with a screw driver to release the tensioner after you install it.
