Well, let me add this followup to this old post. I added a speed sensor to the rear swingarm. Tried the speed sensor on the bike, glitchy. I had the splitter, made an amplifier circuit still acted weird. Maybe it was my tach lead, dunno. But the add on sensor is stone simple (not sexy) but it works. We did 500 miles this weekend and it rocked all the way +/- 1 mph. Very nice to pay attention to the road and not my speed.
Dip switches on mine are all off except #7. Normally open switches is how I made my switch box.
I had to disconnect the tach lead and ground it. Other sites echoed my issue (engage for a few minutes and drop off) and Rostra recommended to disconnect and ground it out. Could be that we are two cylinders and that may make the module a little nuts. Or, we just have some rfi issues and they have a weak filter.
What I did: Added the Rostra speed sensor and bracket with it anchored on the RH swingarm. I added 3 magnets to the rear wheel RH side inside the depression for the disc. JB weld does it again. If there is any brake dust on the magnets it will get cleaned off when I clean the rear wheel (as is the ritual anyway).
Next I will circle back and add a clutch disconnect using the neutral detect on the module. From what I see another relay and maybe a diode ought to get it done simply. Plus now that it works, I will machine out an aluminum sensor cover to hide the ugly.
NOTE: If you add the external sensor from rostra shorten the provided harness to just what you need. Do not bundle it up. There is no shielding and it will act strangely if not at all.
