All clutches tend to stick when not used,
I suggest when you go for ride, put the bike on the centre stand,
With it on tickover, put it in 1st,
Blip the throttle with the clutch pulled in,see if you can free the plates,
Sometimes change up to 3rd or 4th,and do it,
Obviously make sure the rear wheel is not touching the ground,
Should free it,
The more you use it, the better it will become,
