Cold Start / Chain Tensioner / Busted Motor JUNK TENERE ??

[Commuter Boy]

Fwiw, I'm a former aircraft mechanic and have rebuilt bike motors before.

My choice would be drop the motor, spend $2k to buy one off eBay or from a scrapyard, and shoehorn it back in after doing a valve check and CCT upgrade.

Then flog the old one here or on eBay for $1000 with disclosure and let someone with time and skills fix it up.

You will have a running bike in a week, no worries about the quality of the work done on the rebuild, or if they missed something, be good for a valve check interval, and can recover some of your costs.

Again, check the valves for carbon... known issue.. During the time you have owned it, have you often revved it up to 6-7K often ? IMOP, probably no need for a new (used) motor. This is probably a pretty simple fix.

If it was mine I would put it back in time and do a leak down test before ever pulling the head.

THIS x 100.


I had issues with chain noise following a valve adjustment, then a no start, then compression test showed ZERO. I assumed my timing had jumped and I had bent valves. Opened it up and confirmed exhaust cam had jumped 2 teeth. It was late, so I went to bed.


Next morning I tear into it, get the cylinder head off and the valves are perfect. Even tho I'd thought of it the night before, I didn't re-check compression after re-setting the timing. That would have given me "good" readings (the valves were fine), and I could have avoided all the extra time and money (head gasket, $100 worth of bolts) and been back on the road that much sooner. Now the engine's out and I'm waiting on parts to put it back together.


I'd say if you're mechanically inclined - or at patient, willing to learn, and willing to deal with it - AND you have the service manual, you have nothing to lose. I would gladly take it off your hands if you want to just be done with it.


Points:
1. it may not be as bad as you think.
2. you can do it yourself if you're of a mind to.
3. it's the cheapest option forward.


Of course, if you hate wrenching, want a new bike, or can get a ins payout, a new(er) bike would be a lot quicker and less hassle.

Easy check to see if valves are damaged is just check valve clearances. Any valve bent or held open by carbon deposits, (hard to imagine), will have huge clearances in the check. If valve clearances good, valves can't possibly be bent.

The leak-down check is a LOT faster and easier.

Leak down test would be a lot faster except he will have to get into it to retime the cams so it would be just as easy to check clearances.
He will need a reliable cct first.

Alright. I'm scared. Starting to here tap, tap, tap on start up for a second or two on my 2012 Tenere. Ordered a new CCT today from partzilla just in time for my 24k maintenance work. I noticed the part number is the same 2012 thru 2016. Anyone know if they have always been the same or Yamaha decided to use a "newer, better" one on the older bikes?

 

[eemsreno]

There has been 4 CCT for the Tenere
23p-12210-00
23p-12210-01
2bs-12210-00
2bs-12210-01

The last one is the new for 2017 Tenere and the only one you can order now right from Yamaha

Thanks! Then that should work.

Leak down failed. "leaking all over"

I like the idea of just re setting timing (if that's the problem w/ skip) pretty sure it is.

WHATS THE BEST WAY TO GET A SERVICE MANUAL ??

Thanks !!!

The only legal recommendation we can allow here of the service manual is to purchase it through a dealer or authorized online retailer. However, there may be another member nearby who has one they could loan you...

You would have to retime the cams "before" the leak down test.

unofficially is this a possible reasonable resource? Ipad?

Better delete that info, as anything but Yamaha official hard copy would be bootleg and infringing on copyright laws. Moderators will remove it and it is against the rules of this forum............

We know that there are online Gen1 manuals in other countries but the one thing we have to take seriously is copyright laws here in the US where the forum is hosted and forum mgmt resides.


Folks - Zepfan lives near Escondido CA. Is there anybody else in the general area with a manual?


btw -
The link you posted was for one of the cheap rip-off copies of the Yamaha publication. I personally know of people paying $10-$15 for those and receiving either a poor scan of a paper manual, or getting a manual for totally different Yamaha products, including even an outboard boat motor. It really is one of those "get what you paid for" items.

So which one of those four is the one causing the trouble? I have a 2013 and my dealer wasn't sure if mine was one that should be replaced. I will be getting my valve clearance checked at the next service interval and was thinking that would be the time to change out the CCT. Is this when it's normally replaced?

As I understand it, the first revision of the CCT was for the 2014 model, so any model year before that is likely the first one on the list.

Check with Greg the Pole, he hasn't listed it for sale, but he might have a manual.

 

[Zepfan]

I ordered a hard copy on fleabay $25.

Started into it. Already frustrated trying to remove valve cover!
Hydraulic lines off the rail and ignition harness pulled up through the frame. Not gonna pry it off or ?? am I. lol

Oh this is gonna be fun!

Do I have to take the motor out of frame for a top end? ( 4 bolts in frame side and exhaust gives enough room?)

lol went back out and got the cover off.
