Seasons Greetings!
Enjoying my 1992 K1100 LT thanks to the help here I have a great bike! (see pics)
Latest thing I am doing is replacing the Front Mudguard (rear section). For reasons only known to himself (and perhaps the fairies), the P.O. hack-sawed through the rear section removing the larger extended part that is specific to the 1100, so it looks more like that of a K75/K100.
I have managed to get a replacement K1100LT rear section but can't see how it is fixed o the fork, I know it has 1 bolt (10mm IIRC) top centre into the rear of the Fork Brace, and 2 allen bolts at each side (for the top sides of the mudguard), but the corner of the right-angled section must fit into something to hold it in position?
There were 2 brackets on the forks that were held on by the caliper retaining bolts, I still have these but removed them as they didn't seem to serve any purpose. I thought these may have been for mounting lights or something ... maybe these are for mounting the right-angled part of the rear section?
Tried searching and 'fiche but parts just floating in air on diagram etc... any help much appreciated.
Attached pic of what I am (going on and on) about :-)
Cheers

BINGO!

Thanks Laitch!
Does i the mudguard section screw onto those brackets?
I noticed there was a sealing strip on the 'fiche ... maybe it's stuck on somehow?
-
BINGO!
Maybe some K1100LT owners will chime in here instead of squandering their time giving thanks or watching ball- and manhandling. :-)
In the meantime, from what I view on Max BMW's parts fiche:
- an adhesive single- or double-sided strip of foam is attached along the inside edge of the mudguard indicated by the green arrows,
- industrial velcro strips are attached along the brake mudguard mount indicated by the red arrow to mate with corresponding strips attached to the mudguard,
- a spacer (gasket) might be attached to the upper portion of the brake mudguard mount to apply tension to the mudguard
- the mid-section of the mudguard is attached to a boss on the fork slider (blue arrow).

Much of this Rube Golberg-style assembly seems intended to stop the guard from rattling. Perhaps all will be revealed in the fullness of time.

The lower sides attached to brackets via hook-n-loop (velcro) tape.
Plus the threaded fasteners you mentioned.
It's a flimsy mounting system at best but I've yet to have it fall off.
-
Maybe the sides were removed for better brake cooling?

The quasi-bikini fender replaced it as a style statement, more likely, giving the moto that lean and elegant look only a Dremel cutting disc can provide. :-)

On the "new" rear section that I have, there is also a hole near the right-angled corner, definitely looks factory ... but I can't see what it is supposed to line up to.
There's a hole in the brackets that are fixed by the caliper retaining bolts, but that doesn't seem to line up with the hole in the corner of the mudguard rear section. Did the RS model have a different rear section of the front mudguard, with a hole in it?
Re: the brake cooling/modern art ... I think the PO took the artistic statement of the dremel effect to new heights, with the ingenious application of a hacksaw (to the bike) and Irish Whiskey (to himself). The "horizontal" lower edge echoes the peaks of the Mountains of Mourne, and brings a whole new meaning to the term "spirit level".

You're being a little too coy with your descriptions. Are the two holes you're describing on the panel of one side, the other side or both sides? Step into the twenty-first century again and provide more photos. Like the one attached.

The RS has a different mudguard so forget about it.
Some images on the Net show no holes. :johnny Apply a spirit level to yourself, get some Velcro and foam tape then go crazy. The purpose of the hole will be revealed to the faithful.

Must be fun bleeding the brake with the stock mudguard. Is it possible the previous owner did the surgery to avoid removing the mudguard for brake service?
-
Exactly. I wonder if they changed the rear section of the mudgard/fender to protect the caliper from the elements a little?
Am I right in saying the 1100 Brembo pads are more "open to the elements" than the previous K75/K100 design, as they don't have the protective cap/cover plate of the earlier caliper?

Removing two or three screws then peeling it off Velcro mounts doesn't seem hernia-inducing. :-) The K1200 requires removal of four screws. OMG!
Maybe Scott_ will draw us a true picture of this horror. He has one.

... it really isn't that terrible to remove the rear guard. Yes the top allen screw, then loosen the 2 side screws, peel the dual-lock apart.
