Default '86 VT1100 Pulse Generator

After months of trying to figure out why my bike was conking out when hot, we traced it down to the pulse generator. Now another frustrating 2 weeks of looking for the part on the web, calling all over the nation, and posting on salvage yard web sites -- still can't find one. ANY IDEAS ANYONE?

You may have to get one from a different model bike and modify it to work on yours. I,m not sure which ones are adaptable. but i do know its possible. Perhaps someone who has done this will chime in.

The pulse generators for most of the 1980s Hondas were about the same. The bracket that they were attached to was different to fit different engines, but getting a set of pulse generators from a different model and re-working the bracket to fit your bracket is probably your only choice.

Justin, I would love it if you are correct but ... others on the web are saying that the pulse generators have to be specific for the motor size, and very few are interchangeable. Nevertheless, it's worth a try. Do you know any one that has successfully interchanged these for different models?

Tubes probably hit on it. the only real difference between any of the generator used on Hondas of a given year is the length of the wire and the mounting bracket. BOTH of witch could be worked around. The generators are afterall just a magnetic pick-up.

I do NOT have a 1986 Honda Shadow VT1100 pulse generator on my 1986 Honda Shadow VT1100 and it runs awesome!

I believe mine is off of a goldwing.

Yes, some modification was necessary but it was easy stuff (for my skill level anyhow).

Part of the joy and triumph of running ANTIQUE motorcycles is working around little problems like discontinued parts! Sounds like '80s Goldwing pulse generators are a direction to pursue!

Thanks for all the input. I'll tell you the outcome after we try the work arounds. :/

Default Outcome

We found a new pulse generator from a 1987 vt1100 and modified it to fit my 1986. Accidentally switched the wires because the color coding was reversed, but after figuring that out, the bike works ok. I say "ok" because it is still stumbling below 3000 rpms (and yes, the carbs have been recently rebuilt).
