ShadowDog500 posted a great video on adjusting points on the Ironhead Sportster. Messing with ignition systems on older bikes (or news ones) always sounds a bit intimidating to me, but ShadowDog500’s tutorial clears up a lot of the mystery and provides a concise explanation of how to get the job done, including dozens of tips and tricks you won’t find spelled out in your shop manual.
The electrical system on my project bike, a ratted-out 1984 Honda VT700C, is giving me nightmares. I’m in the process of replacing nearly every electrical component on this bike, including the wiring harness.
Between eBay and OEM replacements on Amazon, I’ve pretty much managed to get everything I need, except for one major component: the ignition control system.
In fact, on the 1984 VT700C has three separate boxes controlling ignition. I’m not really sure what each box does, but here’s what I need:
2 x IC Ignitor (red label) TID12-11 A ME9, mfg. Hitachi, Ltd.
1 x ICU-06 ME9, mfg. Hitachi, Ltd.
I have no clue what those numbers and letters mean, only that the replacements I can find are just as suspect as the boxes I gave on hand.
In researching this problem on HondaShadow.net, I came across a reference to a Czech company that has some experience making replacements for these old black boxes.
The company is Ignitech, and they have a wide range of programmable ignitions. Of course, getting the right ignition means emailing photos of your existing mess of wires and parts. But these guys have a reputation for getting it right, so I’m going to give it a shot and have them build me a new ignition system.
