I'm considering running 5mm wires because it will be easier to run down the backbone and under the seat (where I hid my coil) but I've never used it. Anybody here got any experience with it? I'm looking at the Accel Thundersport product, if it makes any difference.

Electronic ignition? if so where is it mounted? I'd worry about radio interference.
Plus I'd run them in a sheath if they are close to the frame. Two sheaths if its a single fire setup.

Yes, Stock HD electronic ignition and coil. Ignition module is in the stock location and the coil is a couple inches away on the other side of a steel bulkhead.

My first concern was also RFI and EMI. That's the main reason I asked for opinions. Sheathing pretty much negates the benefits of the smaller diameter, so I may as well use 8mm at that rate.

I beleive we might be over thinking this. Stock e-ignitions, while they work well, dont come with 8mm wires to begin with, so 5mm should be ok.
