No , but I called the dealer to inquire about the gear guard and timing chain service today. I'll be sitting down when they call back tomorrow with the amount.

Re: Has your BMW K bike experienced a Cam Chain Failure?

Last week Beecher and I installed the fix on my '08 12. Today I recorded Beech installing the fix on his 13. Getting ready for the '49-er now, but after we get back I will edit the recording on my wife's iMac and then post it on YouTube. It'll be cool, but not nearly as cool as that guy's post of the R1200GS oil change.

Maybe there should allow multiple voting for people who have or have had more than one bike.

Don't mean to go off topic here but Muddy1 posted in her thread on her misfortune that,

"K1300S & GT - apparently, the 1300's have more than a few improvements. The Guide rails have been strengthened with deeper sprockets to prevent it from jumping time. Also, the cam chain tensioner was redesigned to prime immediately at start."

Are you merely putting in the jump guard as preventive maintenance or has it been proven that the fixes made to the K1300S are not up to the task??

The jump guard costs $10. It takes any halfway-competent mechanic 15 to 20 minutes to remove the clutch cover, remove the old gasket and clean off any oil contamination on the gasket surfaces, then pop on a new gasket and install the cover with new bolts.

The cost of the jump guard is peanuts; it's the gasket and the non-reusable aluminum screws that cost the big bucks. An hour and a half labor is a ripoff!

Re: Has your BMW K bike experienced a Cam Chain Failure?

The K13 fix is hopefully up to the job. I just put in the jump guard on mine because it fits and is "possible" insurance to help out. The way I read all the current information. If you own a K12 series, I would check out the installation of the up graded K13 chain and guards. If you have a K13 series, just ride it. And if you want to worry more look at that oil pump chain slack when you do your jump guard installation.
Also, the jump guard installation is one of the easiest maintenance items you can do. If you can set your valves you will have no problem with the jump guard installation. Just buy all the parts (screws etc).

Just a matter of easy and cheap insurance then with the added peace of mind,

I understand.

T, if the need arises, it can be changed. However, the poll results are as I had suspected. FEW of us have had this cam chain faiiure, but the knowledge that these parts might fail K 1200 bike riders, stranding us at any time, is disconcerting, to say the least.

Let's keep the knowledge flowing about this issue.

Terry, thanks for the detailed information! I'll post mine when the bike repairs are finished.

Re: Has your BMW K bike experienced a Cam Chain Failure?

Almost 6% failure in my opinion is pretty bad, considering the problem is the heart of the machine. BMW was very slow to acknowledge the suspension link problem, but they finally did fix it. We can only hope for a viable long term solution that doesn't require expensive interval maintenance.

If YES , please post:
year --2007
model -- GT
mileage -- 32949
original warranty -- Yes, barely
extended warranty
out of pocket expense - cost $0
details of parts damaged

Parts replaced:
Chain tensioners (1 set +1)
Slide rail
Sprocket wheel set with chain
8 exhaust valves
8 intake valves
Oil pump
16 valve guide seals
4 bearing shells, cover side
4 bearing shells, rod side
plus a rafty-gaggle of shims, bolts, gaskets, etc.
They also had to send the head out for machining, not sure why.

BTW, this is the fourth cam chain tensioner in the bike. The first was replaced because of the start-up rattle, the second failed on the test ride after it was installed, so a third one went in!

The bike was running great with no significant mechanical noise when we stopped for coffee. Went out and when the bike started, it sounded like shaking a garbage can full of dishes! Was started like this a few times by service techs to try to diagnose the problem so that probably damaged the valves. I thought they'd replaced the pistons as well but evidently not from the work order.

Can't say I'm impressed by some of the engineering on this bike.

Re: Has your BMW K bike experienced a Cam Chain Failure?

My 2007 s was running fine as I pulled up to a stoplight . It died just as I stopped(which it often did) . When I hit the starter button , all hell broke loose .
32000 miles when the exhaust cam broke just inside the cam chain gear.
new head , 2 new valves , new cam chain , new exhaust cam and a bunch of other stuff . $3300 worth of parts . All covered by warranty including a trailer ride to the nearest shop (90 m. to Bentonville BMW) . The guys at Bentonville even loaned me an almost new GT to ride for 6 weeks !

So your bike failure was the result of a camshaft break, not a chain issue... Nothing you could do about that, other than wonder how that should happen these days

not too bad when taken into the context that it is less than 100.00 more than what they tried to charge me for fixing the corrupted file they down loaded into my bike during a routine 12k mile service, took almost 4 weeks and a lengthy email to the pres of BMWNA to get them to step up to the plate and my bike was under warranty when they did it --- I am among those that is growing weary of the attitude coming these days from BMWNA

Yeh...that's a new one. If you recall the original release of the 05 K/S was aborted because of cam problems. Improper hardening of the lobs as I recall. No issues that I've heard of since...

Hey, Doug... I flew through Talullah Falls a few hrs ago - dodged a few storms and remained dry - but HOT!!!

The S now has 115k on the clock, and some new Conti Road Attack2s - SWEET. I wish they raise the speed limit on 441 in TF to 80

Re: Has your BMW K bike experienced a Cam Chain Failure?

I voted 'no' - but all this talking about cam chain failures recently got me so nervous that I installed the the cam chain tensioner AND the cam chain guard yesterday. The bike is a 2005 K1200S, close to 40k miles, thrashed on a regular basis and maintained very 'loose'... I usually don't care too much about valves, oil and cooling - but the mention of the possible repair costs now got me worried...

BTW: I used Roy Bertalotto's excellent description as a guide to complete the actions: THANKS! http://www.i-bmw.com/showthread.php?t=35336

Re: Has your BMW K bike experienced a Cam Chain Failure?

I recently had my 06 K1200S in the shop to check out some clutch whacking noise whenever the engine coughed while idling. Had the jump guard installed then.

Now I have "peace of mind" about this bike... LOL

Ditto to ILLUVATAR, but at around 23K miles. Same damage. Now at 36K and no further problems with this. I understood cost was approx $16 K to BMW.

What did the dealer say about the "clutch wacking"? Mine does it too. Almost as loud as a dry clutch

Re: Has your BMW K bike experienced a Cam Chain Failure?

Just bought a very clean 2005 S with 13.5k miles up, and had uprated cam chain tensioner and jump guard fitted.

Can you include another voting option - 'Not Just Yet' . . .?

The mechanic found some damage to the clutch basket and a couple of plates, but managed to avoid total replacement by using a couple of clutch plates left from another job. After the fix, the noise was much reduced so the noise I heard was likely from the damage. A total fix is about 1000 dollars.

Re: Has your BMW K bike experienced a Cam Chain Failure?

I just replaced my cam chain, sprockets and rails at my 60,000km service plus installed the jump guard at the same time. The chain was quite stretched, making me wonder if the tensioner had much more opportunity to take up slack and the crank sprocket worn enough that if it were your chain and sprockets on a non shaft driven bike, you would have probably replaced them too. Oil pump chain tensioner almost out of adjustment as well and still looser than I would have liked - this makes as much racket if not more than the cam chain, particularly on the overrun. Not sure if this cam chain stretch is a function of nearly 50,000kms with the lousy plate tensioner before I heard about and went to the oil damped tensioner? The rails looked much the same and the old ones didn't really look worn to me. The new chain had a more substantial link, more rectangular than the old, maybe this has been beefed up. Also you can reuse the RHS engine cover gasket if you are not hamfisted and I replaced the one time use bolts with Titanium M6 x 25 ones off ebay and 1 x M6 x 20mm. They are around $2ea, a similar weight, look cool and are reusable. Torque to around 9Nm approx or just nip them up modestly. Cheers.

Re: Has your BMW K bike experienced a Cam Chain Failure?

Heard the cam chain rattle one morning. Pretty distinctive sound, and I started thinking about getting the guard installed. About a week later, heard it again. Didn't wait for a third time. Easy to do, most of the work is getting the right-side plastic off and not confusing which screw goes where. Already had an inch-pound torque wrench, and it took all of 3 seconds to put the guard in place. Buttoned up, no leaks, no eyebrow-raising noises.

I didn't think the jump guard would have anything to do with the chain rattle.
I wonder if you have a problem with your cam chain tensioner.

Re: Has your BMW K bike experienced a Cam Chain Failure?

I have the plastic anti-jump guard, and my 2008 K1200S came with the late model tensioner. This was after the bike sat for about two weeks. I figure it was the bike telling me that she needs to get out more frequently.

I own a 03 K12RS with about 30,000 on it. Is this cam chain issue something I need to address as well? I just want to be safe rather than sorry. Any thoughts or comments would be appreciated.

No - there are other issues on the K12RS, but this cam chain business is a K12S item.

Care to elaborate on this or point me to a link that lists them. I've had the rear seals changed when I had a new clutch put in. I also changed out the gas line connectors that failed. I'm sure there are other issues that I'll need to address sooner or later.

In a few words, it's a decent band-aid. BMW apparently doesn't have a cam tensioner design that will work properly.
Once in a rare occasion (your definition of rare may be different than BMW's), the oil drains out of the tensioner. I haven't been riding it every day, so the combination of sitting and cold weather (by California definitions) would slowly allow the oil to completely drain out of the tensioner. When starting, you get oil pressure fairly fast, but for that small time waiting for oil delivery, the chain can be slack enough to slip one or two teeth on the crankshaft gear. With the plastic guard in place, during initial startup the chain can't rise up far enough off the crankshaft gear to slip while the tensioner is oil-deficient, and subsequently the tensioner snugs up the chain.
The K1200RS had a ratchet mechanism along with the oil-based tensioner, so even with a loss of oil pressure, the tensioner kept the chain fairly tight. I don't understand why they would go away from that type of tensioner. The chain is going to stretch, but it's never going to contract.

Re: Has your BMW K bike experienced a Cam Chain Failure?

Amen to that. I guess a tensioner with ratchet mechanism as on the RS costs a few dollars more, and so is to be avoided. Evidence of cost saving is everywhere on the K12S, and indeed all modern bikes. My 2005 model only has acoustic wadding inside the right hand fairing, not the left. On other bikes, how much does a fully LCD instrument panel cost, compared to the RS's display of proper clocks? The manufacturers will say it's hi-tech and light weight - but really it's there because it cost them $3 from China. I do love my S, riding it is an almost telepathic experience, but gone forever are the days when production bikes were built up to a spec. Now it's always down to a price.

Yes to the question. Changed to the new tensioner per warranty and the chain came off the gear and bent two valves. No problems since the repair now with 38K. BMW covered the repair as the tensioner was replaced under warranty.

great discussion, lots of information.

Based on what I have read here, this issue is mostly related to the K12 series? just trying to determine if I need to take action on my K13R.

From what I understand, the problems have been with the 1200 series and were corrected in the 1300.

I think the installation of the jump guard is a good idea. I am doing mine once it warms up. http://www.i-bmw.com/showthread.php?t=35336

Perhaps on the later model K13 series... Mine is an '09, and I had the new cam chain guide installed per recommendation of my dealer (San Diego BMW), which is a no-BS, trusted source... $117.75 for parts and labor...

I took the small cover off and can see I do not have the jump guard on our 2011 K1300S's. The 1300 has the new sprockets and tensioner, but it looks like most still need to have the jump guard added.

Cover



You should be able to see the jump guard once you remove the cover. In this picture there's no guard.

Talking did the plug seal with an o-ring...

Lee, tell me please...
did that 'plug' come with an o-ring as a seal?
Or what.....(and I bet you've got the torque-value as well...)

BMW told me that according my VIN number, my bike is equipped with a 'jump-guard' factory wise already, but.... if it is that easy to get this confirmed... I could look and see my self if 'they' tell the truth..

btw great pictures and info for the masses, thanks Lee.

Or what.....(and I bet you've got the torque-value as well...)

BMW told me that according my VIN number, my bike is equipped with a 'jump-guard' factory wise already, but.... if it is that easy to get this confirmed... I could look and see my self if 'they' tell the truth..

btw great pictures and info for the masses, thanks Lee.

It had a hard fiber looking ring instead of a normal o-ring.
The torque value is not much, but I can't remember the value.
Some days I can't remember shit
You need a T60 to remove the cover.
I did a search and found the torque is 30 Nm.

Re: Has your BMW K bike experienced a Cam Chain Failure?

Last gen toyota camries are doing the same thing, the seconds it takes for oil pressure to build up in the hyd tensioner are enough for jump failure.
