PIAGGIO Beverly Tourer 300 i.e. Service Station Manual page 204

Injection
Make sure that the throttle valve with the control is
supporting the stop screw.
Guaranteeing that this position will be kept, send
a confirmation for the TPS reset procedure.
Reset should be performed in the following cases:
- on first fitting.
- if the injection control unit is replaced.
N.B.
THE TPS RESET PROCEDURE MUST NOT BE CARRIED OUT WITH A USED THROTTLE BODY
BECAUSE POSSIBLE VALVE WEAR AND STOP WEAR FOR THE MINIMUM OPENING MAKE THE
AIR FLOW DIFFERENTLY FROM THAT OF PRE-CALIBRATION.
