I have a new friend, who owns a custom bike shop....
He does both restorations...
and customs...
He isnt a hack shop like OCC, he builds it correctly... like a swiss watch.
Pricey stuff, but if your considering something like this... give a Joe a shout.

One of his trick items is this very small circuit board, to wire your creation correctly... Even has a mini starter relay !! I might stick one on my 500AFX and get it plated!!
