currently have the #5 curve chosen but only because I had read somewhere that someone liked this setting after trying several others.
Well first off I got it completely wrong my previous post - curve #7 has max advance at 28 degrees and curve #5 is the one with 34 degrees max advance i.e. 2 degrees higher than standard. And yes Rick, I've also read the same somewhere on the web, no doubt the same post.

I reckon I'll start with the default curve 2 and adjust from there depending how it drives. And as you say mounting the box in the space that was taken up by the rear airbox certainly provides ease of access.
the old tab washer has an indent on the ID that locks/aligns it with the key slot but it can't do this with the Sachse wheel guide sleeve
I managed to use the tab washer by gentle filing of the tab.
I'm not sure I understand your generator light question but I will try to answer
As you surmised the Darmah used the GEN light to indicate the running voltage and will turn on below ~12v & above ~15v thereby giving an indication of the state of charging system. This functionality as standard is provided by a horrid voltmeter that takes up yet more space (and doesn't always work) but can be provided by some reg/recs. I've fitted a small LED voltmeter that does the same on my daily driver, a Cagiva V Raptor natch, with the added advantage of flashing when the bike is not running giving the impression of an alarm. I may see if I can squeeze one of these into the original GEN lamp.
YEAH! Test riding and relearning how to ride a bike tomorrow.....
Enjoy & keep it upright :vroom:

Hi Rick,

Is the little can in front of your Sachse ignition module the turn signal relay, that normally sits inside the headlamp housing?

Yes; on an 81 MHR the headlamp shell is empty except for bulbs and wiring. That little can is my blinkie flasher.

Thanks kindly, Rick, for the info and the prompt reply.

I like the idea of locating the blinker relay outside the headlamp shell, as it makes replacement so much easier. Gutting the headlamp shell for any reason is not my idea of a good time.

On my '75 860GT resto, I had to make a new wiring harness (gotta love those wiring diagrams done in Italian...), so the small change of the relocation of the relay is no big deal.

Regards,
Richard

Hi Richard: my first Ducati was a 74 860GT! All sorts of goodies packed inside the headlamp shell. It's good that these bikes are relatively basic; keeps wiring simple.
