I bet that's down to the rear crank seal! You'd replace it whilst you're in there. Whole back end off job, but I think more time-consuming than difficult?

Unfortunately not, everything aft of the clutch has to be removed, admittedly in quite large bits. I had a real issue with getting the gearbox parted from the engine, had to resort to prying it apart in a quite brutal fashion, corrosion on all the locating dowels, BMW quality for you - it hadn't even done 20k when I did it!

I wonder if they've checked the master cylinder isn't overfilled?

The older K series, flying bricks, have the same setup.

There's a video on youtube on how to replace the clutch on a K1200...LT, it's an interesting watch (if you're a sadist).

It's how I found out that the LT has an electrically operated centre stand.

I may need to change the mainshaft seal on my k one day, had a slight oil weep from the hole under the clutch housing since I’ve had it but the clutch hasn't started noticeably slipping yet.

Well - disconnected, and then the rear-sub-frame can be unbolted and hinged up rather than completely removed.

The gearbox and final drive comes off as one unit - even has a convenient wheel attached for moving it around.

Sounds like my brother's shitty old Sierra TBF At least you're not layed underneath the bike up on axle stands.

I managed a nice rolling burnout on the K1200R, back wheel spinning up and me trying hard not to scream like a little girl! Good to know about the earlier models being ULEZ compliant, that opens the horizons considerably on less expensive options!

Couldn't imagine that working on the GSA, unless you disconnected the swingarm and shocker from the subframe, and probably the centrestand too as I'm sure that would be in the way. Can't even go and have a look as, thankfully, the overpriced, troublesome pile of crap has been disposed of!
Twice owned a BMW, my mate's rear suspension collapsing at high speed on his K1200S was the final nail in the coffin for mine. And the constant problems with the R1200GSA years later has made me never want to own one again.

I know a guy who can do a Sierra in about an hour, must be the easiest clutch this side of a MK2 Cav, the one with the input shaft that pulled back and the plate on the bellhousing so you could just drop the whole thing out without dropping the box.

He can't be getting much custom for a his trade any more.

Still busy, but now it's half a day stripping to get at the clutch, dropping subframes, shit like that

Mechanics hate engineers.
