I've heard good and bad about them. They seem to have an angoing problem with this guy for one.

I just ran the only numbers on the spring and it comes up blank. Here's the only markings 108 200 F&S 12 95

You may be getting somewhere. F&S means "Fichtel & Sachs". That's exactly what the bulletin was for the Ks, they switched clutches from Sachs to Valeos(?) and you can't switch parts, I think the clutch would not disengage. I haven't looked at that for a while....memory loss, but I know that would be opposite of what you are finding .... that may depend on which parts are switched. I'll look again to refresh my memory, BMW sometimes groups them bulletins and then you open a K bulletin to find information about the Rs. I know they share some of the same transmission innards.

You are right....punched my stamped numbers in and nothing came up. Had to use the painted ones on the other side, then got it.

How about the pressure plates? Them should also be F&S and well stamped with the part number. Asking because there seems to be 2 type of clutches for the R1100GSs, looks like they changed them at the end of 97, same time as they changed the supplier for them K clutches.

As an aside ... what K bike do, did you have?

I had an early 85 KRS and two 87 KRS's. Put a lot of miles on those bikes with very few issues, the worst was the 85 with the sprag clutch and water pump impeller plus I seized a con rod bearing while accelerating hard in first gear. That was fun

Just checked and the plates, they are Sachs too, dated 96 so probably all original equipment.

I was thinking I'd try the 1150 diaphram like RB recommended but might get BMW recommended parts to be safe.

Brand new 85 K100RS,eurospecs cams, the best and fastest in Alaska Blue. Now a 03 K1200RS, love it but sure have to love wrenching at times.Try getting the clutch out of that....been there. Now the swingarm is seized, will take all my mechanical abilities,lots of thinking and some "special" tools to free that one.Stubborn me but not mad enough yet to zipcut it out and install my cheap spare.

Don't you have another thread somewhere on matching the BMW silver paint out of "available in Canada" paints? Can't find it and need that, swingarm and many other parts getting powdercaoted but have to touch up parts I can't remove. Darn dirt roads and chlorides....should know better than using that RS as a GS.

That's the same '85 I had, the euro spec cams were only on the really early models that were imported to NA, they didn't meet emissions standards so the later 85's and all the rest had the detuned version. Love that blue!
The K12 never caught on with me, I went back to boxers and rode my 77R100RS for a few years and then I went to a R1100S in '99.

Loved that bike even more!!.

My friend has a R1100S in his garage just like that one in the back. Hasn't been ridden in year. Yellow...me no like that color. Too Bombardier for me.

EH! I may have something, I am not up to the BMW model designations, someone may tell but if yours is, as I think, an R259 you do want to read the clutch bulletin. Yep...it is under the K1200RSs. If you want it anyway just PM me your email, I have it here in my documents.

If you sort of read between the lines,always have to with BMW,, it does relate clutch plate thickness with the diaphragm spring.Ouf....them sometimes.

I really hate to resurect an old thread but .......

I went and ordered a new diaphram spring and installed everything. I put the pressure plate screws lightly seated so I could get the tranny slipped into position easily. Put the pushrod in from the backside, it was making correct contact so I put the rest of the pushrod arm etc on the tranny, puttoned it all up and the clutch was working fine betweem neutral, first gear and pulling it in to disengage. So, I installed the rest of the rear end, exhaust etc.

Now before installing the starter I torqued the pressure plate bolts, installed the starter etc. The bike fires up fine.

The clutch pushrod now makes no contact, the lever just flops around

I took out the adjuster bolt and installed a longer one. It makes contact with the pushrod but the spring is so totally stiff that it may break something if I pull hard enough and it still won't disengage the clutch.

Now I'm fucked as to what to do next.

seems that I recall someone having a similar issue here not too long ago?

maybe the end tip was broken off of clutch rod, or the clutch spring was installed backwards, something like that I think it was?

my memory is bad, Ill try and search around for the thread

Yes, I would like to read that!

I'd appreciate that.

Unless I'm a total ass I made sure the spring was installed correctly, even did the test fit while assembly. It was only after the bolts were torqued that I lost contact but I don't see the things moving that much from snug to tight.

Not looking forward to full dissasembly as I'm in the middle of moving

I think that first post hit the nail on the head. I had the disc redone and the plates resurfaced at a local clutch shop and the thicknesses are probably different so than stock so just like installing the TT or VW disc I'll have to adjust with shims.

Well live and learn

I saved a bunch of money but lots more work.

Started this thread on the dead clutch disc, but the disc and the spring etc are available thru Motobins in the UK, assuming they ship OK to your location (I'm in NZ and they get here in about 2 weeks thru airmail). I've had the pattern ("NewFren", italian) one on a previous K1100 for around 10k with no issues... main thought if the parts were so expensive locally then maybe using mail-order could help. YMMV
