The Kawasaki FE400 is a 0.4 l (401 cc, 24.47 cu-in) single-cylinder air-cooled 4-stroke internal combustion small gasoline engine with horizontal shaft manufactured by Kawasaki Heavy Industries LTd., for general-purpose applications.
The FE400 engine has an OHV (overhead valve) design; cast iron cylinder liner; reciprocating balancer; float type carburetor with fixed main jet; flywheel magneto transistor type ignition system; mechanical governor and recoil starter with automatic compression release (electric starter was available as an option). The engine uses full pressure lubrication with spin-on oil filter and low oil shut-off system; dual-element air cleaner or oil bath type air cleaner as an option. The Kawasaki FE400 engine uses hydraulic lash adjuster, so valve adjustment unnecessary.
An 87.0 mm (3.43 in) cylinder bore and 67.5 mm (2.66 in) piston stroke give the motor a total of 401 cc of displacement. Compression ratio rating is 8.3:1. The Kawasaki FE400 motor produced 13.2 PS (9.7 kW; 13.0 HP) at 3,600 rpm of horsepower and 26.5 Nm (2.7 kg·m; 19.56 ft·lb) at 2,800 rpm of torque. The FE400G – 1/2 cam gear reduction.
