Designed to replace the 91FX yet retain the same mounting dimensions but with increased power and torque.
The design has been optimsed to produce strong torque and power at modest RPMs and exploit the extremely effective nature of the E-4040 silencer. This concept becomes important as noise becomes less and less acceptable.
Like all the latest AX series engines, the highly effective and unique cooling fins keep temperatures under control and the carburettor, the precision you would expect from OS.
