5.2
Start ( when the engine is already warm)
The process is the same as this with a cold engine, but you do not have to use the choke here.
5.3
Gear change
The gearbox allows you to control the power transmitted to the rear wheel. That is very useful for the
hill starts, the accelerations, the hills and the bends…
This diagram shows the way you must use to change the gears thanks to the gearshift lever.
WARNING
:
It is recommended not to ride on the neutral for a too long time, especially when the engine
does not run. Do not tow the bike for long distances, even on neutral. The lubrication of the
gearbox is only sufficient when the engine runs. The problem is that a lack of lubrication will
damage seriously the gearbox, even the engine of your bike.
It is essential always to operate the clutch lever when you change the gears. Otherwise you will
damage the gearbox, the engine and the transmission. Those parts are not conceived for such
shocks and stresses, caused by the change in force of the gears.
5.4
Fuel consumption reduction
The fuel consumption directly depends on the way you ride. Despite everything, a few tricks can help
you to save up in this field :
Release the choke as soon as possible.
Change quickly the gears, without letting it rev hard during the acceleration.
Do not accelerate needlessly during the deceleration or during the stops.
Stop the engine when the traffic jam is long enough, or in front of a level crossing.
