A 52.0 mm (2.05 in) cylinder bore and 36.0 mm (1.42 in) piston stroke give the FA76D engine a total of 76 cc of displacement. The compression ratio rating is 6.4:1.
The FA76D engine produced 1.7 PS (1.25 kW; 1.7 HP) at 4,000 rpm of maximum horsepower and 3.1 N·m (0.3 kg·m, 2.3 ft·lb) at 3,200 rpm of maximum torque.
The Kawasaki FA76D features:
- One piece hypereutectic aluminum-silicon alloy die casting with plateau honing cylinder and crankcase
- Hard-chrome plated aluminum alloy piston
- Two compression rings including silicon carbide (on an iron base) plated top ring, and one oil control ring
- I-beam cross section, heat treated aluminum alloy connecting rod, with large bearings
- Heat treated ductile iron crankshaft, integrated with counterbalance weights and camshaft drive gear
- Forged 21-4N austenitic stainless steel exhaust valve and forged heat-resisting steel intake valve
- Magneto ignition with waterproof molded ignition coil. Breaker system standard or electronic ignition system (optional)
- Pulse pump carburetor or float carburetor
