I'd go with the stock plug and benefit from the hotter spark.
Keep in mind that hotter plugs put more heat into the head. I'd keep the cooler plugs in. There are reasons to run hotter plugs but I don't think they're need.

Found out that 87-99 plugs have a 12mm thread diameter.
Plugs for a 2007 have a 10mm thread diameter
So it's no go anyway.
My choice would be the NGK Iridium DPR9EIX.
Any thoughts?

The answer is no. The reason for the relay is to bypass the inadequate small coil power wires and use a larger coil power wire to carry more current to the coils. The small wires will cause a voltage drop where as the large one will not have such a voltage drop off. The relay is energized from the time the key is turned on, to the time it is turned off. There is no delay as it is on the entire time the bike is running. {snip}

if the relays are wired correctly they will be on all the time not just when the coils fire

A relay is nothing more than a coil that when energizes closes a circuit, That circuit is what fires the spark plug in this instance but there is a delay between when the coil fires and the switch closes. This is what I am talking about.

Hueristic: the relay does not switch like you're thinking. It turns on, and then stays energised for the whole time the ignition switch is on. It uses the normal supply to the coils to operate (energise) the relay coil.
On the contacts of the relay (normally open contacts - closed when the coil is energised), a very low resistance piece of wire comes directly from the battery (essentially) and then feeds the coils with a minimal voltage drop. The switching of current through the coils (to make the spark) is still done by the ignitors like it is at present.
Does that help? A picture would explain it immediately, words are a bit harder.

Dang! And I thought I had this all sorted in my head
Back to Ajax sniffin' for me - might clarify things a bit
