ADJUSTMENTS
Fuel level
Turn over carburettor and let float rest on the needle valve’s damper spring
without pressing.
Check distance between bowl gasket seat and uppermost edge of the float
with proper gauge.
Float level = 24 ± 2 mm.
Adjustment is made by bending slightly the float tongue.
Engine speed at idle
Check and adjust idle after having made the necessary engine adjustments.
The engine must be warm in order to set it correctly.
Turn idle adjuster screw until reaching the recommended engine speed.
RPMs at idle: 1300 ÷ 1400 rev/min
ENGINE OIL AND FILTER REPLACEMENT
The engine oil replacement must be carried out with engine warm.
Remove the oil level and filter cap (fig. 9).
Loosen the oil drain plug (fig. 10) on the bottom left side of the engine, then
remove it carefully not to damage the mesh filter on it. Let the oil drain
completely.
Clean and blow out the mesh filter and then remount it and pour 2 litres of oil
into the filler cap.
Check oil level.
Start the engine, then stop it after an idle period of approx. 1 minute.
If necessary add some oil and check for leaks.
Every two oil changes, it is necessary to replace the filter cartridge; the correct
oil level is reached with 2.2 litres of new oil (remove filter cartridge using
appropriate tool 19.1.20520) (fig. 11).
Install new filter after lubrication of its gasket with engine oil.
Recommended oil: AGIP SAE 15W/40 or AGIP SINT 2000.
ENGINE OIL LEVEL CHECK
Stand the motorcycle in a vertical position, on a flat surface.
Start up the engine and let it run at idle speed for about a minute.
Stop the engine and check the oil level through the transparent oil-window on
the left side of the engine (fig. 29).
If necessary, remove the oil cap on the clutch guard (fig.30) and add the
recommended oil to the engine until the maximum level is reached as shown in
the oil-window.
