   Wednesday's coffee gave me a lesson in resistance. Electronic resistance, and its properties in protecting electronic components from "backed up' electrical pulses. I just got home to discover on my Norton, equipped with aftermarket Boyer Bransdon electronic ignition, that while my NGK copper spark plug wires DO NOT have resister tips, I am using an NGK BPR7ES resister plug.

  Thankyou for shop class today lads!!!!

Ah yes, plug and lead resistance and where/when to use them is something seldom properly considered. Especially when you have the older point-less ignition systems or even more critical you are using magneto sparks !
People seldom use their radio so radio-interference is not much of an issue these days.

My Goldwing begs to differ!

  Do they bother offering signal/noise ratio, with the wind noise?

I've never used the radio while riding.  One of the speakers needs to be changed out so I don't even like the sound when parked.  There is a CB as well that I've never used.

I should have clarified, and mentioned radios and loud pipes.

What year is your Wing? I have a spare set of Clarions with housings from the '81 GL1100.
