I was going to go this route but then I blew up my stock transmission.
I've now got a Baker DD7 in there and my god, I am happy with the gearing.
Plus I can still run up and down the highway at 90mph without breaking a sweat.
Not sure if you've ever even considered the swap but it solves the gearing issues, and you're already tearing into the bike pretty far. Transmission comes out with a couple more tools....
