I would look at the recommended fuse that is in line with the battery, and size it to at least meet that.  A lot of considerations go in to wire sizing, but that would probably be the quickest way to make a good choice.  Maybe upgrade one size if the wire is still flexible enough for the wiring harness.  The fuse or circuit breaker is there to protect the wiring.  If a load like a light bulb were to short out, the fuse would open instead of the wire melting or starting a fire.

You have to use stranded wire, NOT solid! 

Replacement used and NOS harnesses are available, and someone here on the site makes nice correct replacements.

I've never seen wire sold by "ampage"...  usually it's sold by wire gauge or by mm2 so that's kind of interesting.  

Not sure what the highest current wire on the bike is...  but 6 volts x 8 amps = 48 watts which sounds barely adequate so I'd probably go for the 17 amp minimum

I'd contact member DEET as he makes complete harnesses using the original wire sizes, colors and connectors. I don't know why you'd buy bulk wire and try and rewire a bike.

Sticking my nose in here, but a couple of pertinent points:-

1) DEET's work comes highly commended.
2) If the value on the CN22 customs form is shown as less than £135, then my understanding is that UK VAT (20%) is not charged (the taxation rules changed on 01/01/2021).

Alan, I think the VAT at 20% is still applicable. I think the change was where the VAT was collected, the onus is on the seller to collect it as I understand it. I think the £135 figure is the threshold for import duty.

And the seller is the one who decides what to put on the customs form....
