One thing you can do (no promises)
Tie your clutch lever back,
( start or not start the bike, up to you, to increase vibration to dislodge any air bubbles attached to the clutch piping system)
Idle for 10mins, turn off
Leave overnight with lever tied back.
Hopefully that will assist with removing any air bubble within the system.
I do this with my 1100 when I do the clutch and brake flush.
Just food for thought, mechanic's may correct me ???? But it works for me
