Hello !
If the Woman was the original owner she may have documents for the bike with the key number tab glued on them.
With the title, a copy of your identity document and this number, every BMW dealer will get you either a key or a switch witht he correct key in it...
Bet which option is cheaper ;-)
Part of the issue is that I truthfully was planning on flipping this bike, and with that I wasn't planning on titling it in my name. Here in IL it'd run me $115 for the title and another $40 for the plate for a year's registration.
I've already got a hexhead GS, a Rotax 650, and a 85' R80 to ride. This was purchased as a project for the winter and I was planning on taking it to my local BMW Swapmeet in the spring.
The rest of the bike is straight forward and all the parts are there, except for the ignition..
I'd found the Emgo 4 wire switch and several other options on that same line but was hoping to find something a bit better, or even better, something with BMW parts.

I'll keep hunting..
I do have the original owner's name and address and will look up a phone number for her. I'm also not 100% she's still alive, as the gentleman I bought the bike from picked it up in a auction with several other items over 5 years ago. He is a bike restorer, but specializes in vintage Euro dirtbikes and he didn't want to take on this project, knowing nothing about BMW's.
I'll keep hunting..
Thanks!!
