8 RIDING INSTRUCTIONS
The motorcycle has been out of use for more than 1 week
Turn tap handle of the fuel tap to the ON position.
Remove the plug-in stand.
Shift the transmission to idle.
Condition
The engine is cold
Press the kick starter robustly through its full range.
8.3
Pull the clutch lever, shift into first gear, release the clutch lever slowly and at the same time open the throt-
tle gently.
8.4
Shift into a higher gear when conditions allow (incline, road situation, etc.). To do so, release the throttle
while simultaneously pulling the clutch lever, shift into the next gear, release the clutch lever and open the
throttle.
If the choke function has been activated, deactivate it after the engine has warmed up.
After reaching maximum speed by fully opening the throttle grip, turn the throttle back so it is ¾ open. This
will barely reduce the speed but fuel consumption will be considerably lower.
Always open the throttle only as much as the engine can handle – abrupt throttle opening increases fuel con-
sumption.
To shift down, apply the brakes and close the throttle at the same time.

Info
If the motorcycle is unwilling to start, the cause can be old fuel in the float chamber. The flammable ele-
ments of the fuel evaporate after a long time of standing.
If the float chamber is filled with fresh fuel, the engine starts immediately.
Empty the carburetor float chamber.
Fuel can flow from the fuel tank to the carburetor.
Pull the choke lever out as far as possible.
Info
Do not open the throttle.

Starting off

Info
The plug-in stand must be removed before riding.
