Adjust idling speed
NOTE: Warm up the engine before adjusting the idle speed.
Use the adjusting screw
1 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.
Adjusting the throttle cable
A play of 3-5 mm must at any time be left in the throttle cables. To
check the play of the throttle cables, first push back the protective cap
2 on the throttle twist grip. Now it should be possible to lift the outer
sleeve of one of the two cables 3-5 mm off the adjusting screw
4
before resistance is felt. The play of the throttle cables can be adjusted,
if necessary, using the two adjusting screws.
For this purpose, undo counter nut
3 and turn the adjusting screw until
the desired play is achieved. Then tighten the counter nut and replace
the protective cap.
After adjusting the throttle cables turn the handlebar all the way to the
left and to the right while the engine is still running. The idle speed
should not change.
Check float level
Take off the float chamber, press down the float frame and hold
carburator as shown in the picture. The float
5 mooves downwards.
Turn carburator slowly until the float moves towards the carburator. In
this position the edge of the float
6 must be parallel to the sealing
surface of the carburator
7.
!
CAUTION
!
IF YOU HOLD ON TURNING THE CARBURATOR, THE FLOAT WILL PRESS AGAINST THE
SPRING OF THE NEEDLE VALVE AND A CORRECT CHECK IS NOT POSSIBLE
. IN THAT
CASE THE CARBURATOR IS TO BE TURNED BACK AND THE CHECK MUST BE DONE
TWICE
.
If the two edges are not parallel, correction can be done by bending the
lever of the needle valve. At the end a check is necessary again.
