Hi out there. I'm in the States and having a hard time tracking down some ignition coils for a 1985 K100. The supply has dried up, but someone knows where they can be obtained. Thanks

Is this what you're looking for?

It is, TY

I used a set of these with great results:

Premium Quality Dual Tower Ignition Coil - BMW Airhead & Moto Guzzi; 3.0 Ohm; Primary Resistance / EnDuraLast
Part #: EDL-Coil3.0OHM

I can send a pic of how I mounted them if you wish.

How long have they been installed on your '85, and how miles have you put on them? Please post some photos and perhaps some description about your installation.

Gheez, let me finish my Saturday morning coffeeeeeeee....

OK let's go!


A) Original cover used. Blue dots (rubber plugs) on right side something I had laying around. 

BONUS: One can ream out the hole on a dual power accessory bracket for use with standard automotive plugs.





B) Using a grinder I removed the rivets on the original coils to use the coil cover mounting brackets. This setup allows only the left side brackets to be used.

A homemade bracket from leftover parts after a bathroom sink repair cut and used to connect coils.




C) Parts I cut and used to make bracket.





D) Bottom View showing wires soldering inward.






E) Rearview showing mounting setup.


Installed last autumn before the winter snows and 200 miles ago, so far flawless performance. Great cold starts at freezing temperatures. While you are at it, now is a good time to remove the fuel tank and clean all the electrical connections.

I have also added high resolution pictures as a ZIP file for download from my non-commercial website.

Can the administrators move posts 7 & 8 to the technical library?

Or maybe create a "HACK' category?
