This is might seem strange to some but I've said stranger stuff before. I have a 1994 Honda Shadow 1100 v-twin with dual carbs. If an emp were to occur, what parts would get fried?

Anything electrical. The computer, solenoids , ext.....
I see what you mean about the solenoind by mine has no CPU. I watched a video of a car getting EMP'd & the power windows still worked. Does that mean my fuel pump might still work?

Humm I'm not to sure. When it comes to electrical me giving you advice is like Hellen Keller leading Ray Charles across the street. If your welling to try I have seen someone show how you can test it. Bad thing is it will fry it if it fails.

Lol nice :D
Hmmm, I might need a faraday cage tested :rolleyes:

What kind of ignition does yours have? If it has the old points like in the 1970's, you might be OK, but i would bet electronic ignition controls will be the problem.

I'm not sure what points are :confused:

If it has a distributor cap it has points. Replace those and the coil and you are back on the road. If the wires come directly out of the engine it has pickup coils and magnets in the flywheel like a lawnmower or weedeater. Replace the pickup coils and you are back on the road.
If you want to know what points are find an old early 70's car or truck and take the distributor cap off. At the base of the distributor you'll see 2 "claw" looking pinchers with contact pads. They open and close to allow juice to flow to the spark plug. It's just a mechanical spark control module.

Ok thanks. I'll check to see what they are.

It has wires coming out or the right side behind the cylinders. Hope the parts are cheap lol.

Just find a really cool old Harly knuckle head or somthing. That way it will run and you will look cool! LOL :D

I might be wrong but I think that any electronics that are not powered up and being used will not be affected. Carry a spare ignition module and you should be OK. That is as long as you know how to replace it.

Or disconnect the battery. If the circuit is broken emp cannot energize it

It depends on how much energy is in the EMP- (inverse square of distance- it drops off as you move away)

In one of the H bomb tests in the Pacific, they burned out streetlights in Honolulu. Enough energy, anything electrical that is not shielded gets fried. Some things (solid state electronics) can be fried easier. If it has a chip, it fies easy. Vacuum tubes- takes a lot.

Generaly speaking, if the low voltage dc system on your mc is not on or the battery is disconnected it will be safe. Faraday cages are a bit more comlcated than most think. A safer with more protection would be have the battery out of your mc. Of course that would make it not as useable. Any electronics on it are probably fried.

Street lights since the late '40s have had a small solid state photo eye and starter. These are what burned out in Hawaii. Wire wound coils that are not excited with electricity when an emp happens are not going to be bothered. That means generators, starter motors, ignition coils won't be affected. ANY solid state/computer type electronics will more than likely be fried. Vehicle battieres are the big question.

Having an old desisel tractor with manual fuel shutoff will be one of the few vehicles that emp will not effect.

If emp was strong enough to burn up wire wound equipment, it would get us too. Electronics only need minor actual voltage to fry.

A bike of that vintage should be electronic ignition with a cdi box ( ignition module that controls the coil, grounds it to collape the field and make it spark ) problably mounted under the seat near the strip of fuses.

You can buy a spare or tear a piece of tin foil off your hat and wrap it ;)

Your ignition igniters will fry for sure. And,more than likely, anything connected to the charging system. They didnt use the rectifier setup like the did in the 70s-80s.
I would get an old honda Ct-90 for my bug out bike. They will run 35-45 miles and hour, use sips of gas, will go almost anywhere. They have points and condenser so get a few spares of those. The early ones, (late 1960's/early 70's) will run with out a hot battery .
