Help identifying a retaining spring

[rbm]

Hi,  I bought some K1100 parts for a paralever conversion.  The seller delivered the items separated.  Included in the parts was this retaining spring:



I can't positively identify it and I hope that someone who is more familiar with K1100's can help.  I know it's not the retainer spring for any of the footrests.  I thought this might be the rear brake pedal retainer spring, but it doesn't match the OEM fiche diagram.  Any ideas?

Not sure exactly, but it looks kind of like one of the parts for the automatic side stand retrieval system.

Rear brake lever.

Thanks Duck.  Do you think the spring can be adapted to a K100 brake rear pedal mounted on the K1100 footplate?  I don't have the K1100 version pedal (it wasn't included in the purchase).

Yes, the brake pedal, part 35121450887, is the same on all classic K bikes. The mounting is a bit different I think though.  Contact me if you need help with that.

Bingo Max!  It turns out it is the retaining spring ( 46532311037 ) from the side stand retractor mechanism.

I tried every orientation to get that spring to work on the rear brake lever and just couldn't get it to fit. Researched parts on Ebay and concluded the rear brake lever return spring is differently shaped.

The hook on the spring points in the wrong direction.....to be attached to the brake pedal.

Seems odd that would come with K1100 parts since K1100 don't have the retractor like the 2V bikes do.

In the deal, I also asked for and received the centre stand.  Most all the parts in this diagram ( http://www.realoem.com/bmw/showparts.do?model=0526&mospid=51710&btnr=46_0114&hg=46&fg=10 ) came along with the paralever drive assemblies.  There were many loose parts in a bag which I'm sorting through now.  You'll note the spring, #15.  There was a retractor mechanism included as well.  This all came off a 1995 K1100LT.

Part #15 is for the sidestand switch mechanism......hmmm, could be that one also....seems like a closer match.

K1100s did not come with a side stand retractor.  All of the 4V K bikes used a switch (#19) to kill the bike with the stand down.  Very odd that a side stand retractor would  come with K1100 parts.  Probably just a bunch of miscellaneous stuff thrown into a box.
