I sent an e-mail to Haynes to see if they were going to come out with a manual for either the gen1 or 2 XB's, here's the quote from their reply

"Although we do not yet have a manual published for your vehicle, we are planning to produce one in the near future. Please check back with us in October, 2009, when we should have more detailed information for you.
Again, thank you for your interest in Haynes automotive/motorcycle manuals!"

So will it be a Gen 1 or 2???
