At Charlotte Motor Speedway back in 1978...North Carolina Highway Patrol Radar clocked the bike (with an open factory exhaust, open intakes and factory 4c camshafts and other bits) at 148mph on the straight.
In the state of tune today..our modern very poor pump fuel, Jota exhaust, axtell camshafts, geared back to street specs and a factory air box and filter, probably 135 to 138 mph.
Dave Minton tested a Laverda 3CE prepared very close to my bike in its present state of tune back in December 1975 for Motor Cyclist Illustrated magazine. He was shocked by the power and recorded well above 130mph.
Not bad for an old bike.
