Starting when the engine is cold
1 Open the fuel tap [1].
2 Swing up the side stand or center stand.
3 Put the gear in neutral.
4 Operate the choke [2].
5 Leave throttle closed and kick the kickstarter briskly ALL THE WAY or actuate
the E-starter.
If you want to start the engine, make sure that you always put on sturdy
motorcycle boots in order to avoid injuries. You might slip off the kickstarter,
or the engine may kick back.
Always kick the kickstarter briskly all the way without opening the throttle.
If you do not Kick hard enought, with an open throttle grip, the kick-back
hazard will be higher.
Do not start the engine and allow it to idle in a closed area. Exhaust fumes
are poisonous and can cause loss of consciousness and death. Always provide
adequate ventilation while the engine is running.
Always verify that the transmission has been set to idle (neutral) before
actuating the starter button. If you start the motorcycle with a gear engaged,
the motorcycle will move forward.
Maximal period for continuous starting: 5 seconds. Wait at least 5 seconds
before trying again.
Don’t ride your motorcycle with full load and don’t rev up the engine when
cold because the piston is warming up faster than the water cooled cylinder
and can cause engine damage.
NOTE: If you have trouble starting the motorcycle, this could be due to old
fuel in the float chamber. The easily inflammable components of the
new fuels evaporate during longer periods of standstill.When the
motorcycle has been out of operation for more than a week, it is therefore
recommended to drain the old fuel from the float chamber. The
engine will immediately start off when the float chamber is filled with
new fuel.
Starting when the engine is warm
1 Open the fuel tap [1].
2 Swing up the side stand.
3 Put the gear in neutral.
4 Pull the hot start lever
5 Leave throttle closed and kick the kickstarter briskly ALL THE WAY or
actuate the E-starter.
What to do when the engine is “flooded“
The fork legs must be partly disassembled to change the spring preload (see
WP manual). Pretension spacers in various thicknesses are available (see spare
parts catalog).
NOTE:
The carburetor has an accelerator pump. Every time you open the throttle,
fuel will be injected into the intake passage. When starting, be sure that you
open the throttle completely only once.
