The meter of motorcycle is to indicate the working condition of motorcycle.
1 The Structure and Working Principle of Meter
[1]Speedometer
Speedometer is to indicate the running speed of motorcycle and the total mileage.It is driven by front wheel.
The rev of front wheel is sent to speedometer through gearshift system and soft axle,which makes magnetic
cylinder rotate.Coil cuts magnetic wire,which makes whirlpool and magnetic field to cooperate with the magnetic
field of magnetic cylinder,makes whirlpool disc get a torque,overcomes a resistance and drives the finger to rotate.
The higher the speed is,the stronger the magnetic field of whirlpool disc is.The torque is bigger,so the angle
of finger swing augments and it can reach the higher mark on board.Meanwhile,the rotating main axle drives
counter through whirlpool lever.Therefore,the total mileage of motorcycle is indicated by the counter. Maintain
speedometer once a year.Add luboil to where it needs.

2 Disassembly and Maintenance of Meter
[1]When fingers of meter don
’
t work,dismantle
speedometer and check it.
Check meter
[3]Check whether the connection of speedometer is
looseness.
[2]Fuel Meter
Fuel meter is to indicate the fuel volume
in fuel tank.It guides the resistance changes
in sensor which caused by the change of fuel
level to fuel volume indicator and indicates the
change of fuel volume through fuel volume
indicator.
