Hmmm. BP7HS is the same as Champion L82YC which I kind of like for a
relatively cheap, generally available plug. HV is the gold palladium
half-inch reach. Most of the fancy platinum plugs are about $7 to $8 these
days. If you're going to spend that kind of money you might as well buy
Iridium plugs, which will last a very long time. Both Denso and NGK make an
iridium in the 7 heat range with half inch reach, though they tend to be
more common in 3/4"

You might try BP7HVX which is the same plug with a .8mm fine wire electrode.
The BP7HIX may not exist--but it would be the Iridium version. They're about
ten bucks each. 

I find the best source for NGK plugs is still motorcycle dealers--they've
been selling them for eons. They can order almost anything from Rocky
motorcycle parts distributors, and Rocky used to be the US distributor for
NGK.
