Multi-Port Precision
Electronic Fuel Injection, on the F50 - F90, uses four independent
fuel injectors to deliver optimal fuel/air mix to each cylinder -
boosting acceleration, top-end and fuel economy.

Single throttle valve -
simple, lightweight design allowing for quick and easy adjustment. The
air silencer box on the F75 and F90 reduces intake air noise to a
minimum with the use of a highly porous nylon cloth that soaks up the
noise making these engines whisper quiet while the surge tank reduces
air turbulence for smoother operation. |
 |
Composite Intake Manifold
- The long tube intake tracks are tuned to increase air flow increasing
low end and midrange torque performance resulting in a more powerful
hole shot and increased acceleration. The air silencer box reduces
intake air noise while the surge tank reduces air turbulence for
smoother operation. |
