The problem is definitely not the clutch cable tension. I even once tried adjusting the tension very tight, with no freeplay, but the shifting was still difficult. My cable is set according to the manual now--0.5 inch freeplay at the lever tip. My bike has 200 miles odo now, and it hasn't gotten any better, and gotten slightly worse. I'm going to send the bike back to the dealer. Btw, the used bike I test drove shifted smoothly.
