I asked at BGM about this and he said it is not a service item as such... I think I will be doing this myself at some point soon as I have a centre stand, I have a garage with carpet in it and I will have the time at some point to get this rather essential job sorted.
They simply lie,  it is an item of regular inspection.

Cross purposes folks...

Certainly in UK, no dealer even knows they are down there, let alone that failure (seizure, as in the early ones) can kill you nor that a few minutes with a tub of grease (ina BMW workshop???) and a spanner will mean they can keep servicing your bike for many more years to come.

I think Costas means that they MUST be serviced, especially here in UK and I imagine that t'other Costas wouldn't let a bike out of his service bay without giving them a once over.

Took me an hour to strip, clean, grease and reassemble. Nice easy job and satisfying to know that it is all done now.  Just another little thing out of the way.

And yes, the bearings all needed a good dab of grease, they were not dry, but nor were they nicely lubed up.

Hi Guys, I don't know how I didn't find this forum until now and it's only after I had a lower linkage failure that I see this post >

I was lucky that it was a low speed failure and I was on a straight section of road, but it did damage the shock so a replacement had to be sourced, my bike is back in action thankfully and the linkage is lubed up to within an inch of it's life and is firmly on the "to do" list going forward

Well, an interesting day in the garage.

I had applied penetrating fluid last night, and this morning (plusgas - great stuff).

I took the back wheel off tonight and took the opportunity to lube the rear driveshaft splines. They were in good condition, so it's done now.

I then started disassembling the suspension linkage.  The last bolt, the one most forwards with the sunken head, was not for budging. I got the nut off, but no way was that bolt coming out.  I downed tools and backed off before I could cause any damage, and had a re-group. 

I then went back into it, looked at the other three bearings and saw they were all clean and lubed, so I called it good and put the rest of them back together   :D  No point in making a hash of it and reefing out a head.  I'll come back to it next year.

I then replaced the worn out PR4 with a lovely new one, took the TPS out and put in a new battery, and opened up a nice bottle of Italian.

I'd call it a successful night.

Do you think the stubborn bolt will be easier to remove next year?  :-\

Nope, but I'm satisfied that everything was greased up, so I am tipping the balance back to riding it rather than working on it.

I'll look at it when I have the wheel off to change the bevel oil.

Hi Corkboy, just as a matter of interest.  Will the Motoscan allow you to re-initiate the TPS sensors after changing the battery or do you have to visit the stealer for that.

Haven't been out on the bike yet to check it, but from reading the collected wisdom; Once the unit has already been initiated then changing the battery doesn't change that. Thinking about it, the unit spends most of it's life off, only turning on when you ride the bike. So most of the time the battery isn't being used. The unit wouldn't know that the battery has been changed, as it is done during the "off" state.

You only need to initialise a new unit.

And sorry, to answer your actual question (as Richtea has done below), the Motoscan will do so.  If you need it, let me know)

Do you have the torque settings for the bolts when re assembling?
As mentioned in a different post the bolt torque here is 38Nm. with blue loctite (242). Early in these bikes history there was a recall by BMW. The replaced the "dog bone" tie bar with one a little larger and lubed the bearings. Previously this set up was not being serviced regularly and the dog bone was actually breaking on some bikes. I do not see it in the maintenance sheets even now but at the time it was pointed out to clean and grease this part every two years.

4 years or every 50000 km. Is the current technical service recommendation.
