The battery (12 V - 7.2Ah) is a sealed, no maintenance battery and is supplied already
pre-assembled in a support box, which can be easily adapted to all existing chassis.
Both a throttle carburettor and a float chamber carburettor (on the F4 version), can be
fitted on the engine. In this last case, the engine is provided with a fuel pump.
A power-valve is fitted on the cylinder exhaust duct (with the exception of the KF3 version)
to optimize the low range performance. The exhaust system, included in the supply, is
already tuned and optimized to guarantee the best efficiency.
The water-pump, is integrated in the engine and the water cooling system involves both
the thermic group and the crankcase.
The engine (only F3 and F4) is supplied with a kit which includes the homologated
radiator, the water hoses, the thermostat and the fixing supports on the chassis.
