Idleadjustment (03_19, 03_20)
To adjust idle speed it is necessary to reach the set screw located in the carburettor.
To carry out this adjustment it is necessary to reach the catalytic muffler as shown in
the picture, or else by lifting the saddle and removing the hatch located at the bottom
of the helmet compartment.
Turn the set screw for clearance adjustment of the throttle control transmission, then
replace the rubber protection cap. Adjust idle speed with the rear wheel off the ground
(vehicle on stand) and with a warm engine. turn the knob-type head screw in or out
until the engine idles smoothly (around 1800/2000rpm.), i.e. without the rear wheel
being moved by the engine.

WHEN ADJUSTING IDLE SPEED, PAY SPECIAL ATTENTION NOT TO TOUCH
THE CATALYTIC MUFFLER TO AVOID BURNS.
SHOULD THERE BE PROBLEMS DURING THE IDLE SPEED ADJUSTMENT OP-
ERATION, IT MAY BE NECESSARY TO ADJUST THE LEVEL OF EXHAUST
EMISSIONS (CO). THIS OPERATION MUST BE CARRIED OUT AT AN AUTHOR-
ISED PIAGGIO-GILERA SERVICE CENTRE.
