I had a flat black 250 Sprint (I painted it that way), my first street-legal bike, back in, like, 1973. It had HARLEY DAVIDSON cast on one side of the engine (I think the primary side) and a little Harley logo on the small cover on the other side. It kicked on the left, shifted on the right, with one-up, the rest down shift pattern (the bike started its life with a toe-heel type shifter). I had a Norton/Matchless P-11 years later and reaquainted myself with the right hand upside down shifter. Since it was the first bike that i owned and my previous experience was with Honda trail 90 step-thrus, it didn't seem a bit odd to me. Years later I saw a 350 Sprint (post 1976 federal mandates I think) and it looked to me like they swapped each and every part of the engine to the opposite side, like mirror-imaging the blueprints or something. Anybody know anything about that?
