Hello,
in the process of reviving a 1990 K100 and making it more "naked"
is it possible to change the BMW flasher with a standard one (that support leds) and retain the original switches?
i know i will loose the auto canceling function.
i'd love to change all the switches but this will force me to also replace the brake master cylinder and clutch perch, which i prefer not to at this phase.

Thanks
Eran

BMW turn signal switches are momentary and regular turn signals aren't.  You could do it but you'd need to add some latching relays to the circuit.

If you retain the factory switchgear then you're best off going with the factory relay. (Or a Kisan signalmider that's made for Ks.)

Agreed, if you're keeping the OE momentary switches, then it's hard to see how you can beat the OE relay for function/compactness. If your ambition is to lose the OE gubbins box under the seat, then the OE relay could be retained and relocated under the tank/in the seat hump/between two slices of bread with some lettuce etc.

There is a German guy, who is selling a new relay, that will work with LED, Motogadged etc.
It has a Hasard Funktion and has a auto turn-off.
Price is 70€. Plug&Play

when i try to operate the turn signals now i get the following:(no actual indicators attached)
switch is ON
in the dashboard one of the turn signal lights is on permanently
if i either try left or right signals, i just hear an annoying sound - like a broken buzzer
cancelling with the cancel button - stops the sound

The noise is the indicator relay throwing a complete fit. You need the indicators attached to provide a load for the relay.

If this relic has LED indicators instead of incandescent bulbs, start at this post then read to the end to the thread to determine if it applies to your problem.

As Dai points out, without any load the flasher relay freaks out.

K flasher relays generally don't have a high failure rate so chances are it will work fine with turn signal bulbs attached.  The turn indicators in the cluster are on the same wires from the flasher relay as the turn signal bulbs. Blue/red wire for the left side, Blue/black for the right.

To make the relay LED friendly just cut Pin 7:
