1951: a new tank emblem, "Harley-Davidson" in script with a bar underneath.

45" changes: Heads secured w/cap screws, fixed jet Linkert M-54 carb, chrome plated exhaust connection pipe, single stripe rear fender trim.

Panhead changes: Chrome plated piston compression rings were meant to help prevent scorring of jug walls during breakin. A 2 piece cam-(separate gear) was introduced with ramps on both sides of the lobe. Pushrod ball sockets frequently worked themselves loose, so rocker arms were machined with pushrod sockets. The exhaust "S" and "Y" downtubes were chromed and a new shouldered exhaust port clamp was installed, (the shoulder facing the head). Neoprene cork composition pushrod seals improved oil leakage from the tubes, single stripe rear fender trim replaces the sergeant stripes, rocker cover D-ring made of 3 layers of sheet metal spot welded together and fastened by 9 phillips screws and 3 allen head screws. These D-rings were placed inbetween the pan cover and mounting screws to prevent cover distortion caused by overtightening the screws, which caused oil leaks. Midyear saw the M-74B carb which would remain through 1965, also midyear a larger diameter pinion shaft. Optionally for $1.50, you could get a chromed "Hydra-Glide" emblem for the front fender, available through 1954.
