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?

I found this link:
http://amtulld002.bp.com/bpglis/lub...72441127c016253a802571f7004a2401?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/2009/03/08/bmw-k1300gt-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).

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?

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? :confused:


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.

Since the dealer usually does the first 2-3 changes on these bikes until the owner gets the "I can do that feeling," I wonder how the dealer's get around replacing trannys and clutches under warranty if the "approved" oil isn't available?

With the disappearance of the BMW Service CD's and now this "unavailable magical oil," I wonder if they are conjuring up some "Dealer Only Service = Warranty" scheme?

As it stands, doesn't seem their "specified" oil exists in the U.S. per their named Castrol. Therefore, "No one in the U.S. has a warranty."

<just brilliant!> :wtf:

Oh wait. Maybe the engine is sealed for life and doesn't need an oil change just like the '06 finals did when they came out.

<just brilliant!...again.> :wtf: :wtf:

I've been using this oil and its forerunner (as recommended in the '06 manual) purchased from the Superstore by the case as referenced above, for the past 30k km. I have no clutch squeal.

Squeal on easy or hard accel...when you hear it, you'll know what it is. If you don't hear it, count your blessings.

Here's the email reply from Cyclegear.com:
Hi David,

Castrol Power 1 motor oil is actually called "R4" here in the states.

We do carry this product and you can find it here: http://www.cyclegear.com/spgm.cfm?L1=&L2=&L3=&L4=&item=CAS_12904_G

Thank you for choosing Cycle Gear.

Paul

I'll ask Castrol if this is accurate and post their reply.

Castrol says that Power 1 Racing 4T is manufactured in Europe and that they do not have any way to cross reference the spec's. They said to ask BMW if this is available in the US and if so under what name/designation. Getting nowhere fast.

Have any of you ever ridden Japanese bikes that won't clutch properly unless you use a very specific brand of oil? I didn't think so.

Sure, a thinner oil may help here, but the problem lies with the underlying design of BMW's wet clutch. Claiming it's an oil issue is bull.

Besides, I thought we finally pinpointed the problem down to an interaction with the oil pump drive sprocket and the back of the clutch basket. So the "proper" fix is a new, thinner sprocket from BMW.

Not according to our areas BMW field tech. And yes, I agree that different oil is BS, but insisting that they replace the sprocket did not work....so far.

I agree with Ken this is a design problem, nothing a different oil spec will fix. Im confused about the 2008GT having this problem. If I remember correctly, another post not long ago, advised all the 08's had the new sprocket. When did BMW start using the new thin sprocket?

Very good question. I hope someone has a definitive answer. Not only is my '08 doing it, but a buddy's '08 was as well...it bothered him so much he traded up to an '09.

I"d sure like to know why my '06 doesn't do it? And I'm not alone. Might it have something to do with the way it's used?

My worst noise is the cam chain on startup, but I have the fix for that waiting in my toolbox. :teeth This weekend will solve this small aggravation.
