If they are Ducati based engines, I don't see anything wrong with listing them... pssst.. don't tell Chuck.... but I don't list any of my bikes on my sig ;-)
drooool...that's awesome!! Congrats. I'm about to add a Bim to keep the 900ss|sp company, myself!
Since I've already got the 2-valve Duc, I want an SB-6/6R. I'd prefer the original 6, but if the price is right on a 6R....
