Sprint 350 was the Bronson bike for all the stunts the main eye bike wasn't up to.
Although the Sprint pictured looks like a conglomeration of several years, is most likely a ’67 or ’68. ’67 was the first year for the Top End pictured and the engine side covers, carb and other goodies changed in ’69.
Another fairly useless piece of trivia is that the Sprint didn’t come with any kind of ignition timing mark until around ’72. FWIW, a Sprint set a World Land Speed Record in 1965 in the 250cc class. I had a ’66 and a ’69 Sprint. I shortened the wheelbase on the ’69 350 when I stuffed it into the front end of an Oldsmobile in 1971. Are those Bitubo shocks on the back of that old roach? Sweeeet.
Michael Parks was the original McGiver. He could R&R a crankpin or countershaft with little more than a pocket knife and a paper clip. One episode had him straightening the fork tubes over a campfire; great stuff!
