Today i went out for a short ride... it was meant to be longer but my clutch developed something 20mins into the ride. i can only explain it as feeling like the plunger isn't moving in/out smoothly (squeeky almost). the first thing that came to mind was I need to put some grease on the pivot bolt but then it became worst and next thing i knew I'm not feeling any power into the rear wheel even when I'm giving it gas. The wet clutch is not engaging. I stopped the bike and opened the reservoir's lid to see if I have fluid in there (there is plenty).... covered it up and for some weird reason that did it and i was able to head back home with what seems to me a normal-feeling clutch. what just happened? any idea? should i be sending this out to my dealer for a check-up? anyone had this happen to them?
