No, a value below 100 for GEGO or AFV indicates overly rich from 14.7-1 and a correction is being made by the ECM to remove fueling. A value above 100 is correcting for leaner than 14.7-1, a leaking intake manifold gasket would cause a value above 100 as more air than intended is entering the motor.
Only 3 reasons (actually 4) I can see causing an overly rich condition (real or indicated).
1.) Injector not fully closing as cooter states.
2.) Faulty/dying 02 sensor sending an incorrect reading (bike is not actually richer).
3.) Faulty fuel pressure regulator flowing more than factory regulated pressure to the injectors then intended (fuel map now becomes overly rich). and
4.) If someone messed with the fuel tables with software or changed the EEPROM.
EDIT:
5.) AND if it is a DDFI2 bike and the TPS has been reset to the wrong butterfly degree (zero'd wrong) the ECM will go off the fuel table values you wrongly set the TPS at.
