Cam Chain Noise

Guys my bike has the standard 2 or 3 seconds of rattle at cold start up while it waits for a drink but over the past few thousand kilometers i am hearing what sounds like cam chain rattle on deceleration when at full temperature.

Its more pronounced at low speeds but probably only because there is no wind noise to take it away or drown it out.

In addition, my engine revs are quite lumpy at idle as I assume they all are but over the past few weeks the low revs in the lumpy idle cycle are also producing a little chain rattle as well.

Has anyone one else had this issue and if so can you shed some light for me.

The bike is going into the dealer this Thursday for the intermittent brake pad warning light and a pre safari check up so it would be nice to have some facts on hand before I get another " they all do that"

Thanks in advance

P.S its only done 12000klms or 8000 miles.

Yes, they all do that but no, it isn't "normal" nor should it be acceptable.

Mine is finally fixed after 53K miles. It had gotten so bad that just pulling up to a stop light would start the rattling as the bike settled down to idle.

There is a newer cam chain tensioner, which you can see below. The old part just had a flat plate for a top cover, while this part has an upper reservoir that holds oil so that the tensioner pumps up to the correct pressure much sooner, thus eliminating the rattle.

By the way, they said any wear on the chain or chain guides was minimal and that they should easily last 100K miles.

If your dealer doesn't have the info on this new part, tell him to look up Service Bulletin #5221209-01 (though that may be a US-only bulletin). Max BMW shows the part number as 11 31 7 717 288 but I'm not absolutely sure that's the latest number. It does look correct from their drawing though.

Finally

That sound is annoying as hell. It's not that bad but it's annoying!!!

I took my '07 K1200R to the dealer and he told me it was the clutch housing...

Apparently not though. I'll take this info to the dealer again.

Thanks.

But do all K1200's do this?

I had the new type cam chain tensioner fitted and the cold start up rattle is gone.

I still have the deceleration rattle that sounds like a chain though. This may be what your dealer is referring to re the clutch housing.

Im not sure if its doing any harm but it sounds gnarly and it annoys me.

Here are some pictures of the new tensioner and new vs. old. Partnumber is 11.31.7.711.473.

Does anyone have a copy of the service advisory? My dealer first came up TADT, then when I mentioned the service bulletin (they did not disclose it's existence, I had to mention it) I was told that BMW wouldn't cover it under warranty because it was 'just a noise.' I have read elsewhere (can't find the thread) that the bulletin does specify that it is covered under warranty so I'd like to see a copy if anyone has access to it.

TIA,

Mine was covered under warranty but I'm not sure of the bulletin #. I would push the issue a bit harder with them and if they won't cover it, contact BMWNA and find another dealer.

I have an '08 with the new cylindrical cam chain tensioner and although it does quiet down at start up quicker than my '07 did, the "cam chain rattle" sound is still there at times. I do think it is hard to hear at speed due to wind noise, thus hard to tell if it is there all this time.

A buddy of mine has an '09 and there is no noise at all, although he doesn't have many miles on it.

And those who were seen dancing were thought to be insane by those who could not hear the music.
