Checking the adjustment of the hand decompression release
cable *
Start the engine and, at idling speed, slowly pull the hand decompression
lever until you can feel the thumping of the rocker arm on the lever. The
backlash until said thumping should be approx. 10mm, measured at the
lever's outer end. If necessary, correct this backlash.
To adjust move back the protective cover
1, loosen the counter nut 2 and
correct the adjustment screw 3 accordingly. Tighten counter nut and push
back protective cover.

I
F THERE IS NO PLAY IN THE DEKO-LEVER, THIS CAN RESULT IN ENGINE DAMAGE.
NOTE:
No adjustment need be made to the automatic decompressor.
Adjusting the throttle cables *
The throttle grip should always provide for a backlash of 3-5mm. Besides,
with the engine running, the idling speed must not change if you turn the
handlebar all the way to the left or right.
To adjust the throttle cables, dismount the seat and the tank together with
spoilers. Slide back the protection cover
4. Loosen the counter nut 5 and
turn the adjusting screw
6 accordingly. Turning the adjusting screw coun-
terclockwise will reduce the backlash, turning the adjusting screw clockwise
will increase the backlash.
Tighten the counter nut and check whether the throttle grip can be
actuated smoothly. Mount tank and seat.
Checking the oil level of the hydraulic clutch
