I'm building a CB500 special from an old neglected bike and was worried about the ancient corroded switchgear. You can find good stuff for a prince's ransom but luckily I found an alternative. I also own a Kawasaki Z900A which has switchgear identical in function to the CB500, same number of wires from the same places but with different colours and the only other difference being cable that stays on the underside of the bars rather than through holes. Far better in my opinion.
Z-Power sell these RH and LH units for around £70 a pair new.
