I just did this work on a 2008. Clutch travel was 0.05" (1.27 mm). Runout was 0.005" TIR. To measure runout, I put the indicator near the OD of the pressure plate. With the clutch pulled in and the bike in gear, I rotated the back wheel to get the plate to spin. This is not a machined surface so I think 0.005 is quite good. The clutch worked OK but would not change gears when stopped. It was also stuck at start up. I have not ridden it enough to see if it is now different. If I remember correctly, my 2002 Sherco had 0.04" of travel.
