Bike's been sitting for a few weeks while I waited for parts. Just went down to move it and noticed the clutch felt abnormally heavy. So did the bike when trying to roll it forward and back with the clutch pulled. I'm also hearing / feeling a soft click / clunk after rolling about an inch in either direction (also with clutch pulled). But when I actually put it in neutral, it feels light again, easy to roll, and no soft click / clunk. Thoughts?
