Before taking the cover off : check if the pressureplate is getting lifted evenly.
Put the bike on the stand, clutch in and kick a few times 'till it's loose.
Then put it in gear, pull the clutch and wiggle a bit with the rear wheel.
If it's better, chance the clutch will have to undergo some checking.
If a spring is broken, the plate tends to lift more on one side than the other, and NOT disengaging completely.
Also : the outer basket and inner core can get dented by the discs. Those discs then get stuck in the groves making disengaging difficult.
And of course, the clutch nut can come loose, giving it a hit and miss action.

Somewhere in the dark recesses of my memory the figure of approx. 2mm seems to rattle around. Make sure the plates are completely un stuck, which will probably require it to be run/used and warm.

Hello Wdietz186,

..nearly 2 mm ist exact the way of the pressure-plate, that i´ve measured out on the pressure-plate, left side, und inspection cover...is that enough to separate all clutch-plate from each other ???...I´ve thought, it must be a minimum of approx 5-6 mm ???
Ciao,
Joe

Today, by a friend, we´ve find out on 2 bevel 900 Duc´s : The "way" is about 2.35 - 2,4 mm , measuring on the presure-plate...!
