gday tews,the clutch might just need the adjustment done at the casing,just infront of your right big toe is a small locknut with an adjustment screw,the plates also might have been frozen together after such a long sit,the oil is gonna have to be changed that might also help,does the lever feel like it hasnt got the full stroke?it might have the wrong cable on it?,the 500 one is similar but wont work on a 550 and wont de-clutch fully,some times if you just pull the clutch apart and put it back together itll work better properly adjusted etc,have you got tools?if you bought the bike do you think you could drop the clutch cover off and dissemble the clutch yourself?its not real hard,down load the workshop manual here somewhere(someone else might provide a link im too lazy),talk the guy down and say the clutch is gone south etc and the shop wants XXXXX$ to fix it etc,,good luck.
