have you got the pe cable or rm?
as smed said pe has inline adjuster as well as the adjuster at the bottom wich screws into the clutch cover
either one no matter, do up adjuster (shorten cable) so to give adjustment after,
now cable is at shortest and mounted except for clutch lever arm at the front of clutch cover, remove that arm and position so as to give a little slack in cable,
then (on pe cable) you have 3 points of adjusmemt
1 on the bars (clutch lever perch)
2 inline adjuster in the cable
3 adjuster at and on the clutch cover
let me know if any more info needed cheers
