The bike belongs to Mike Ortiz (sp) of Billings (/) MT. You can find some pics of the bike under construction at www.aeracing.com, click motorcycles then on cool pics 2, I believe. Sorry I don't have the intellect to lead to the link itself.
His buddy Donny Beer, who's brother Dusty has won the Billing hillclimb " a few times", also built one. I think that Donny might have taken his bike to France for the Labour Day Le Monte Impossible Hillclimb. I am unsure if he did and unsure of his result. I know Dusty won the event, which was billed a World Championship event by the promoter who had FIM sanctioning.
My buddy Ken Long rode and finished 4th behind Dusty. I'll try get some links to the French hillclimb or others where the bergs are climbing.
