You will have best results staying with the stock NGK plugs. DPR8EA-9
Honda designed these motors for these plugs and there have been many that have tried to use other plugs only to find they wasted money at best, were stuck broken down at the worst.
New plug wire and spark plug caps would be a much better investment of your money as they get to leaking and I have seen corrosion in the wire connection at the coils here on the coast on my 83.
NGK offers new plug caps and bulk 7mm wire (6') with new plugs will run @ $35 Dollars total investment here. I'm not sure of the amount on your side of the pond.
