I had a thread about this the other day. My bike is doing the same thing. I can actually feel something click or vibrate the clutch lever. Mine seems to only do it when upshifting (just as I'm about to release the clutch lever). I am in the second half of the break in period now and was hoping it would quit but it did it once or twice again today.
Mine appears to do it only on upshifts, not downshifting. If I don't use the clutch at all for upshifting, it doesn't appears to ever do it. But, not using the clutch in street traffic is hard to shift smoothly.
I don't know what the problem is but I am having the same problem.
