Building something of stuff taken from the collector parti può essere un affare complicato. Basta chiedere il dottor Frankenstein.
Ma questa fabbrica 1929 Harley-Davidson hillclimber è la prova che con ingegno sufficiente, una collezione di pezzi può essere trasformato in un corridore unico e competitivo.
Larry Ketzel, un hillclimber precoce Harley-Davidson che ha anche trascorso del tempo di lavoro nella fabbrica Harley, messo tutto insieme.
"Ha detto che aveva un'idea su come farlo veramente funzionare", dice l'amico Ted Ponton di Salinas, in California. "Ed era un uomo molto intelligente, acuto reale.
"Lo ha chiamato fatta in casa speciale," Ponton aggiunge.
La cornice è da un hillclimber 1929, e il motore was intended for a '29 model JDH road, so I called a 1929 Harley Ponton. However, this is just the beginning.
The engine of 74 cubic inches (1,230 cc) JDH was used as the base. Ketzel then incorporated flywheels JE 1929 61 cubic inch (1,000 cc). The cylinders are based on a 1930 project by a 21-cubic-inch (350 cc) "blowpipe", a single-cylinder Harley. But this series is specifically expressed in Ketzel's specific to the Harley factory. Only 12 were ever made. The rod OHV, meanwhile, came from two engines share blowgun.
Combine these parts has not been easy. Ketzel Ponton notes that he had to cut half of the exchange only to mount the engine in the chassis. But when it came to reassemble the elements together, he had the bike you see here, a V-twin with all the right parts to go fast uphill in 1930.
There is no doubt that this was a serious racebike. Ketzel removed the oil pump gear-driven and installed a hand pump to avoid any loss of power. It has bumped the compression ratio of an enormous 13-to-1.
Suspension? Another mix of bits. The '29 came with a rigid frame rear end you see here, but Ketzel took a springer fork out an '28 model.
Unfortunately, no records remain to tell us how fast this machine unique was made or how many horses.
"All Larry would never say, 'It does the job'," says Ponton.
But Ponton has home-of-the-pants test the bike was fast.
"I drove up a hill in 1950, the last time it worked," he says, "and was a powerhouse."
Ketzel, owner Larry Ketzel Harley-Davidson Cyclery in Salinas, Calif., for 25 years, died in 1992 at the age of 86. Before his death, gave a special home-made at the Motorcycle Hall of Fame Museum.
