ngk-7803 Locally I can get them here at Advance Auto or O'Reilly's
They may have to order but it usually only takes a day or two. If you order by the 7803 number for some reason they come up cheaper (about $6 a plug) but not bad since they will probably last the life of the bike.
They usually come pre-gapped at .32 but a quick check never hurts. All mine were just fine out of the box.
Also, be sure and use a little never-seize when you install.
