For whatever reason, I'm bound and determined to get my stock Ambo up to 100 MPH. I've got a Sigma Sport speedometer that is very accurate and records my maximum speed obtained. Coming across the Gandy Bridge the other morning I had her pegged nearly the whole way. She got up to 95 MPH and held there, but no further. I'm going to take off my fairing and give it another go one of these days. How fast have you taken your stock Ambassador (750, 4-speed, 8-35 rear end)?
