Connect the DDS and select MONSTER 796 / MONSTER 796 ABS.
Make sure that the throttle body pulley is seated against the stop screw when the throttle twistgrip is fully closed.
Make sure that the throttle cable free play is correctly adjusted.
CHECK:
-that throttle angle reading with the DDS, engine off, is 0°.
Start the engine and wait for the engine temperature to reach 100 °C. When engine temperature reaches 100° C, start
the following adjustment procedure.
Idle speed shall be between 1,250 and 1,350 rpm (1,300±50):
-If idle speed is lower or higher than the specified values, open or close by 1/4 of a turn the by-pass screws (2) and (3)
on both cylinders; once idle speed is fine, check that the CO rate is above 0.4% in both cylinders.
If idle speed setup procedure does not allow you to achieve the target value, proceed as follows:
-Overhaul the cylinder-head assemblies (clearance, timing, valve sealing, etc.).
-Repeat the entire idle speed adjustment procedure.
-check the vacuum pressures downstream of the butterfly valve (carry out this check only after completing the steps
described above).
Warning
If the engine is shut off before proceeding with adjustment of the CO level, wait three minutes after restarting for the
enrichment phase to finish and the lambda sensors to start operating.
If idling rpm is too high and by-pass screws adjustment was not effective, make sure that parts below throttle are sealing
correctly, in particular check for cracks or fissures in the intake manifolds make sure they are securely fastened to the
engine, check for cuts in the pressure sensor hoses, etc.
