Joe has 2 and I've seen the paint on one of them, beautiful.
The only thing I can suggest is to have a chat with him, I do know that he will not build the motor for you but I think you would rather do it yourself anyway (as would I), hints and what to watch for shouldn't be a problem but again, best have a chat to him.
As for info for various bits and bobs, I don't think that will be a problem for him, a little known fact about him is he loves his Kawasaki's, he just happens to build beaut big air cooled Suzuki motors.
How are you for this Sunday? assuming Joe is up for a chat, bear in mind that a quick visit takes around 3 hours 'cause I just love what he does and some of the interesting projects he has going.
