"Perry & Scotts bike was built by a Max Kelly,and had a blower, ran it on gasoline. When Scott acquired it he threw away the blower in favor of running a 'normally aspirated' fueler. A beautiful alloy frame, the likes of Clems' Barn-Job, he just needed better motors and- tuning!"
This has to be one of the best engineered double engine Triumph's ever built. Engineering does not break records though, expert tuning does. Americans didn't have much luck with superchargers in the early days. The British on the other hand mastered the use of them on their dragbikes in the UK.
