The jump was actually made by Bud Ekins. He was a hard core racer, stuntman, and motorcycle dealer. Not a mechanic. Likely difficult to impossible to find his equal.

Ekins won four Gold Medals and a Silver at the International Six Day Trials during the 1960s.[1]
He rode a 650cc Triumph TR6 Trophy as did Steve McQueen in the USA International Six Day Trial team for 1964 held in East Germany. The team, mounted on Triumphs they personally collected from the Meriden factory, also included his brother Dave Ekins, who rode a 500cc Triumph T100 Tiger, winning, along with teammate Cliff Coleman, a gold medal in the process.
He received a gold medal at the 1962 International Six Days Trials in East Germany, and was part of the US ISDT team of 1964 with John Steen, Cliff Coleman, Dave Ekins, and Steve McQueen. In 1965, again on Triumphs, the team competed at the ISDT on the Isle of Man, McQueen being replaced by Ed Kretz, Jr.
Other race success included winning the Big Bear Hare & Hound desert race three times, the Catalina Grand Prix, and winning Southern California's AMA District 37 Number One Plate seven times.
In addition to motorcycle racing, Ekins was active in off-road truck racing. He participated in most of the early off-road racing events including the Mint 400 and Stardust 7-11 in Las Vegas, Nevada. He notably raced Vic Hickey's prototype "Baja Bug" in the first Baja 500 in 1973.
He is a member of the Motorcycle Hall of Fame and Off-road Motorsports Hall of Fame.
