The clutch on my 2002 LC4 Adventure has dragged for awhile now. It has a little over 13k miles on it. If I adjust the play in the cable to 5mm as the manual states, when warm, it pushes the bike forward and neutral is difficult to find at a stop. I recently installed a new clutch cable and had to spin the adjuster barrel almost half way out from the get go. I've adjusted the lever arm at the bottom of the cable to take up as much slack as possible. This seems a little weird to me, although I have very little experience with wet clutch bikes. Does this sound like worn out or warped clutch disks? If so should I just replace all the disks or measure them and replace those that are out of spec? I'm outfitting this bike for a long trip and want to err on the side of precaution.
