Checking and adjusting the choke cable play *
The choke lever must always have a play of approx. 4 mm (0.16 in).
!
CAUTION
!
IF THERE IS NO PLAY IN THE CHOKE CABLE, THE BORE OF THE COLD STARTER SYSTEM
CANNOT BE COMPLETELY CLOSED
. THIS RESULTS IN HIGH FUEL CONSUMPTION, AN
UNEVEN RUNNING ENGINE
, AND AN EXTREME WEAR OF PISTON AND CYLINDER
.
Remove the seat and tank to adjust.
Push the choke lever all the way to the front and slide the protecting cap
1
from the adjusting part 2.
Loosen the lock nut
3 and correct the play by turning the adjusting part.
Tighten lock nut and slide protecting cap back on.
Mount the tank and seat.
Checking the adjustment of the hand decompression cable *
To check, set piston at compression, so that the valves are closed. While
doing this, slowly operate the kickstarter through its stroke until the clicking
sound (disengaging) of the automatic decompression can be heard. Now
the decompression lever must be operated 25 mm (1 in) until resistance is
felt (the exhaust valves begin to open). To adjust move back the protective
cover
4, loosen the counter nut and correct the adjusting screw 5
accordingly. Tighten counter nut and push back protective cover.
!
CAUTION
!
IF THERE IS NO PLAY IN THE DECOMPRESSION LEVER
, THIS CAN RESULT IN ENGINE
DAMAGE
.
NOTE: No adjustment need be made to the automatic decompressor.
Activating the ignition curve for low-octane fuel
If you are traveling to a country where fuel having at least 95 octane (ROZ)
is not available, you can easily activate the corresponding ignition curve.
A socket connector
6 is located on a brown-black cable near the digital
box.
If the two connectors are connected to each other, the ignition curve for
fuel having at least 95 octane (ROZ) is activated.
If you disconnect the plug and socket connection, the ignition curve for fuel
having 80 - 94 octane (ROZ) is activated. Although this causes the engine
to lose some of its power output, it prevents poor glow ignitions and engine
damage.
!
CAUTION
!
IF FUEL HAVING AT LEAST 95 OCTANE (ROZ) IS NOT AVAILABLE, THE IGNITION CURVE
FOR
80 - 94 OCTANE (ROZ) MUST BE ACTIVATED TO PREVENT ENGINE DAMAGE.
Adjust idling speed *
Use the adjusting screw
7
to adjust the basic position of the throttle valve
and, thus, the idle speed.Turning in clockwise direction will increase the
idling speed, turning in counterclockwise direction will reduce the idling
speed. Normal idling speed 1400 - 1500 rpm.
