Eliminating Engine Interference (Through Frame/Handlebars/etc.)

    How would one effectively ground out the motor and/or eliminate the interference coming from the motor?

    Does separating the engine mounts from the frame with rubber help?
    Does wrapping the engine wiring or frame in insulation heat shrink/tubing work?
    Can bare wires tied to the frame cause interference?
    Does one have to scrape the paint off to properly ground against the frame?
    If the 6v white wire is left open, will it help to cap or cut?

    Honestly, if you know a surefire way to get rid of the interference without doing too much work I'd love to hear it.

    I know that using any rubber in a motor mount usually leads to serious problems. I'm not sure if using shielded wire will keep interference away from things that might be affected by it, but that's what I'd try first.

    The interference is RF noise caused by the spark jumping the spark gap. It's like static on an old AM radio.
    The static on the radio when lightning strikes in a storm is the same thing.
    The fix is resistor spark leads, and more distance from the source of the noise as far as I know.
