FEATURES
Twin spark plugs
For this model, two spark plugs are incor-
porated in each cylinder.
By using two spark plugs, the combustion
time in the combustion chamber is short-
ened in an attempt to improve torque.
Speed sensor
The speed sensor is installed to the crank-
case and it detects the number of passing
gears while the vehicle is running in 5th
gear and sends the information out as an
electrical signal to the ignitor unit.
Self-diagnosis device
This model is equipped with a self-diagno-
sis device that has four functions.
The engine trouble indicator light will come
on or flash if trouble occurs in an engine
monitoring circuit.
Refer to “SELF-DIAGNOSIS” in chapter 7.
