motorcycles. The Motorcycle
Performance Guide now has camshaft specifications and a horsepower gallery for the Twin

| Everyone has wanted to know what the new
Harley-Davidson engine was going to be. Here is a picture of the new "Fathead"
engine in a 1999 Dyna Super Glide. It is still a 45 degree, air cooled V-Twin engine. This
engine was a ground up redesign. Harley engineers wanted to create a new, modern engine
that will last 100,000 miles and still retain the classic feature of the older V-Twin. It
looks like they have met their goals. The technical
specifications are:
Bore: 3.750"
Stroke: 4.0"
Displacement: 88 Cubic Inches ( 1450 cc )
Compression Ratio: 8.8-9.0:1
Horsepower: 62 at the rear wheels
Torque: 86 ft. lbs. for Dresser's or 82 ft. lbs. for Dyna's
Fuel System: CV carburetor or Electronic Fuel Injection
Ignition System: Single Fire
Twin Camshafts located in the engine case: Chain Driven
Cylinder Head: Aluminum, permanent mold with 85cc bathtub
combustion chamber, single 12mm spark plug.
Transmission: 5 speed bolted directly to the engine. |
