Just to practice story telling...
I called the local Honda dealer. Tried to sell me a whole ignition lock assembly. Er, won't the seat lock be wrong? Ummm, yeah. After flip flopping about whether or not they could even get a key. They finally said yes it was available to be ordered. Won't you need the MC VIN number? Nah, just take the blank to a locksmith. .....ooookaaay. Thanks anyway.
Fortunately, I had already called a locksmith, who didn't think finding a blank would be much issue, within his locksmith community. We'll see. The lock goes to him next monday. When he will "fiddle with it for awhile and cut a key for it".
He's done well for me in the past. So, with hope...
