'08 Clutch squeal

After some investigation, the wrench at the dealer was informed by a BMW field tech that the latest solution was to use Castrol Power 1 Racing 4T 5w-40. Reportedly this is now available in the US, but I'll be damned if I can find it anywhere. Anybody know if/where this is available?

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

I found this link:
http://amtulld002.bp.com/bpglis/lubt...1?OpenDocument

JASO MA-2 API SL
BMW special approval for K1300 and K1200 series.
Kawasaki special approval for KX450F and K250F models.


So the BMW dealers in the U.S. don't have it, but maybe the Kawi dealers do?

What's worse, I also saw some reports of BMW not warrantying the clutch and tranny should that specific oil not be used (from whomever Rainbow BMW is. Maybe in Europe?). What a load of crap if true!
Link here (see blindboy's comment at end of page): http://cbr1100xx.wordpress.com/2009/...0gt-road-test/

Still, I cannot find that specific oil for sale in the U.S. either. Looking at the JASO specs in bold above, the MA-2 is specified as a higher friction oil for wet clutches and better suited for bikes over MA-1.

That said, maybe Amsoil Motorcycle oil in the U.S. as it meets the JASO standards above?

Gmack, thanks for the links. I am already using Amsoil, and the tech knew this when he said to switch to the Castrol. Re: denial of warranty claims: BMW cannot require that we use an oil that is unavailable in the US.

I bought a case of the Castrol at the end of last summer ('08) and it was available then, the way I got it was to call Castrol (8004620835) and they gave me the number to the US distributor ROMAHA (8005236532).

BMW recommends:
Castrol Power 1 Racing 4T 5w-40

Motorcycle Superstore (U.S.) calls it:
Castrol Power RS R4 4T SAE 5w-40

Any difference or same stuff?

Clutch Squeal Revisited

The thinner oil may reduce the noise effect, but it is certainly not the ultimate solution to Gen II clutches. After multiple attempts to solve the problem on my 07 with 24,500 miles(rework plates, syn oil, new clutch, etc), BMW replaced it with an 08.
Upon receipt of the new bike with 11 miles on the odometer and test riding it, I discovered the noise was detectable. The bike now has 4,500 miles and the squeal is evident. Both BMWNA and San Diego BMW have not been able to provide a solution to this problem. A BMW engineering representative came to the shop's grand opening selebration two weeks ago, discussed my bike, but could not offer provide any fix, neither technically nor with an alternative lubrication. This is an ongoing issue that seems to have the team stumpted.
I am sure there is more to follow. Let's see if we can quantify those of us who have yet to be adequately repaired and are awaiting the silver bullet.

Personally, I haven't heard the clutch squeal on the '06 yet. However, brake squeal "YES!" (+ an "omg" interjected too!)

I've been working microphoning up the bike to a VIO PIO.1 video recorder trying to get rid of tinny-sounding engine noise and haven't heard anything on the sound playback either that sounds like a squeal.

Is this a clutch squeal a "slipping on hard acceleration squeal," some "low speed take-off engagement squeal," or an "only at idle and disengaged squeal" so I can listen for it?

GMack your right it's labeled slightly different, and the cans that say racing all appear to be green, while the RS label bottles all appear tan. If you read the specs for both they seem to be the same, but who knows. The more I'm thinking about this it sounds ridiculous that only one magical oil can meet the requirements for the BMW clutch problem.
