Obviously if the rider has not leaned the bike over enough this cornering force will make the bike stand up and he/she will crash.
If the rider leans over correctly to balance the force then that force has been BALANCED and all the cornering G's are going directly down through the CoG of the bike and rider combination. Thus if the rider wants to change the cornering direction/line of the bike he just needs to alter the bike and rider combination's CoG again. As the bikes is perfectly force balanced this takes no more effort than if the bike was vertical EXCEPT he/she now has the cornering G force to counter. This unfortunately makes it harder for the rider to move because they will be Gcornering * their mass heavier.
Counteracting their request for the bike to alter direction will be the gyroscopic force of any rotating object on the bike, definitely not aiding their request for the bike to lean.

All 100% correct, except you forgot one small detail.
there is one gyro that can be moved in relation to the rest of the bike/rider (or in other words, have force applied to it.)....the front wheel....precession does the rest.
