Clutch lever adjustment is EXTREMELY critical on R3's - "About right" does NOT cut it. It has to be spot on as the manual says or you will hit issues. Too much play and the plates will drag a bit and you won't find "N". To tight and you will wear the lifter mechanism.
On my R3 - 1/8th of a turn on teh adjuster makes a world of difference
