Seems that fellow was quite a character.
Well worth a read @Kevin frazier .
One of the most memorable features of EJ’s drag bikes was the launch. After trying all sorts of clutch setups and continually meeting with failure, they ditched the clutch altogether. Now, raising the rear wheel on the stand, they would fire up the engine, spin up the tire to about 100 mph and one of the crew would push him off the stand. EJ said, “Major leap of technology here.”
E J Potter was the subject on a show in the UK last week “ American Pickers”, the bikes were purchased along with loads of memorabilia and found a new home in a museum so they could be enjoyed rather than being locked away.
Never heard of the guy but some of the footage on YouTube is brilliant,even raced at Santa Pod here in England.
