This is a great question! The change clutch is released momentarily (only) during each shift. So those clutch discs must remain tight at all times except during the middle of a shifting operation. The clutch adjustment bolt you speak of determines the maximum allowed depth of clutch release (spring compression) that occurs from the release cam motion. Both manual shift and electric shift bikes work the same way.
If the adjustment bolt does not provide enough slack to allow the cam to release all tension from the pressure plate completely following a shift, the change clutch will generally begin to slip once you get in the throttle under load.
If the adjustment bolt provides too much slack for the cam, the change clutch will not be completely released during each shift, which results in engine torque continuing to be transferred through the transmission, making each shift difficult or impossible.
In your case there is too much slack being provided by the adjustment bolt. The change clutch is not releasing completely. Reinstall the front cover once you get the locknut and adjuster bolt freed up and adjust per the service manual recommendation. Then test the results and fine tune the adjustment if necessary.
