ACCELERATOR PUMP SYSTEM
This system works only when the rider opens throttle grip quickly as pump send the necessary
amount of fuel to the carburetor bore for correcting fuel/air mixture ratio. When the rider open the
throttle grip quickly, the intaken air volume becomes large and air velocity at the bottom of the
throttle valve (piston valve)is slow and sucking volume of fuel is less.
The throttle valve lever c pulls lever d with the cable, and lever e turns and pushes rod f. The
rod f pushes plunger g. This plunger pushes out the fuel through outlet pipe h, spraying fuel into
the main bore.
