The Kawasaki FH430V KAI is a 0.43 l (431 cc, 26.3 cu-in) V-twin 90° air-cooled 4-stroke internal combustion small gasoline engine with vertical shaft, manufactured by Kawasaki Heavy Industries LTd., for general-purpose applications. The Japanese word “KAI” means evolution, advancement and renewal.
The FH430V KAI engine is based on the FH430V motor, but it uses redesigned air cleaner and blower housings, new air filter options, internally vented carburetor, an advanced lubrication system design, and enhancements for optimal stability.
The FH430V KAI has vertical PTO shaft; V-twin 90° design with cast iron cylinder liners and overhead valves (OHV). The engine is equipped with an internally vented carburetor with fuel shut-off solenoid and electronic spark ignition system. The Kawasaki FH430V KAI engine uses a full pressure lubrication system with spin-on oil filter and dual element air cleaner.
The engine has BENDIX type electric starter and 12V-13A charging coil with a regulator.
It has a 65 mm (2.56 in) cylinder bore and 65 mm (2.56 in) piston stroke. Compression ratio rating is 8.5:1. The Kawasaki FH430V KAI produced 15.2 PS (11.2 kW; 15.0 HP) at 3,600 rpm and 32.0 Nm (3.26 kg·m; 23.62 ft·lb) at 2,400 rpm of torque.
