4-10 FUEL AND LUBRICATION SYSTEM
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 1 turns lever 2, and lever 3 turns and pushes rod 4. The rod 4 pushes plunger
5. This plunger pushes out the fuel through outlet pipe 6, spraying fuel into the main bore.
