1964 Royal Enfield Bullet 350. Gears on right side and brake on left. Bend pipe, short bottle, all original. Runs and drives. New gas tank and tool boxes. Kick start. Needs some work to make perfect. All around good bike.
$5500 cash

That's almost surely an Indian home market "grey import" which snuck into the USA on dodgy "vintage papers", maybe a brief stint with a sketchy mail order Vermont registration. But it's seemingly got a California plate, so with legit papers to match who really cares if you just wanted a street legal low stress 350 thumper? YET, if that thing's a '64 then I was Cleopatra's Prom Date. Hence, the asking price is probably a tad steep. But hey...that's Fresno. They even had T-shirts made up, so caveat emptor...

Poor quality photo, but looking at the front fender, levers and handlebar fittings suggest it may be that vintage.
Getting the engine/frame numbers verified by any potential buyer would clear it up.

Maybe I WAS Cleopatra's Prom Date. I recall some sort of boat ride, but then it all gets fuzzy...something about "the nipples of Horus" and then it all went "steamy". But yeah: let's see a clear detailed photo of the gearbox and area just above. That bolt there, or lack thereof, will clear it up.

Indian Enfield for sure.

The long thru' bolt above the gearbox first appears on Enfield India bikes in early 1962. The only sure way to know if it is a genuine '64 bike is from photos of the frame and engine stampings to see if they factory originals or not.
