I got mine working the issue was my starter solenoid went tits up (tech speak for shit the bed).
I went to Home Depot for a tractor 12V starter solenoid and it worked like a charm.
I don't remember how I have mine wired. I will go out and take a look, take photos and post again.
I figured it out. My starter solenoid was the culprit. There was no clicking sound when I pressed the start button.
I used my voltmeter and tested the terminal that the starter motor connects to. I did this with the ignition switch turned on. No volts.
I went to Home Depot, bought a 12V...
So, I guess there is a safety relay, which is what I’m referring to in my above post. Then there’s the starter relay solenoid. I believe mine’s done, kaput. How can I test to see if it is even working or not?
I’m saying my starter (push start/electronic start) isn’t working. I have my start button control switch connected to the m.button and grounded. The m.button is connected, via green wire, to the m.unit and is also grounded. The ignition coils are connected to the ignition-out on the m.unit. The...
It is hot all the time. I’m wondering if the coils are not receiving enough power (measured in volts, amps, xx?).
It’s a newer pamco electronic ignition. The points were ok but the engine would misfire a lot between 1.8k rpm and ~2.8. The battery also kept losing charge, so I replaced my...
My model is the F, not the 2F. It has disc brakes both front and rear.
It came with contact points but I replaced them with Pamco electronic.
The m.unit blue has an ignition-out port. It also has aux 1 and 2 in and out. I use aux 2 for powering my neutral and oil lights in the speedo which are...
Let me add that the left turn signal flashes on the indicator as well as the Turn L LED on the m.unit blue.
Sometimes I get quick flashes of the LEDs on the horn, turn r, and turn l out of the m.unit.
The manual sucks and isn’t very informative. There really aren’t a lot of posts for this type...
I have a ‘79 xs400(2F). My most favorite bike I’ve ever owned, and I’ve owned six.
I have a motogadget m.button and m.unit blue. I replaced my contact points with an electronic ignition which works great with stock wiring harness.
I ripped out my old stock harness and ran my own wiring.
I...
Looks like no one responded since you posted 2 years ago. I have a similar setup, but have a ‘79 xs400(2F).

Quikyx, what throttle assembly are you using?
I wanted to use a cheap one I found from Dennis and Kirk, but I have to make my own throttle cable.
I'm new to all this bike fixing and modding but it's wicked fun.
