I built a capacitor a while ago to replace the battery on my ‘73 CL450. I finally got around to cleaning up all the wiring and hiding the capacitors. I was able to tuck the capacitors behind the horn and route the wires up underneath the tank. Really cleans up the lines of the bike. Next I’ll be stripping the tank, cutting off the rear of the frame underneath the passenger seat so it doesn’t stick out, and cutting off the tabs for the battery box. I still need to set up my foot controls and set the timing as well.

You actually “built” capacitors? Like wrapping foil around an insulator many many times? Or just wired up factory made capacitors to replace the battery?
Impressed either way but I’d have to bow my head to you also if the former.

The latter. I wired four 10,000uF capacitors in parallel to give me 40,000 uF of capacitance. It’s kick start only, but it seems to work pretty well. Takes four kicks and then the bike starts up. It only works on bikes that have a permanently polarized charging system or a magneto ignition.

Nice! Great heat shrinking job too. Thanks for the pic. Didn’t know you could do this for those bikes. It occurs to me that using different colored wires/heat shrink for the pos and neg leads could be helpful.
ah, I think I see the empty space for the battery. I assume it fit behind the carbs along with the airbox.

I put different colored shrink on the very ends of the wires near the leads. Yeah, the battery and all the other electronic components went in the space behind the carbs.

If you ever need to upgrade from your measly (/s) 40 mF to 55 F!! I don’t know how much energy a 12V lead acid battery contains in terms of F but my mind can’t wrap around the concept of a 55 F capacitor. The energy in your 40 mF capacitor is difficult enough to grasp.

Mine is a 40,000 uF capacitor, so .04F. That’s pretty cool that that guy figured out how to do that. However, it looks to be about the same size as a small battery, and still a contains a corrosive liquid, which are the two things I wanted to eliminate with mine. Supposedly the bike will run on a capacitor as low as .02F, but I gave it a bit more just in case. Once I get the bike up and driving around I’ll experiment with different sizes.
