All signs of something in your clutch system binding. When you're off the bike and it is running, does it want to pull on it's own? If so, you maybe have 1 weak spring on your clutch, making one shoe grab a little bit. Without a freewheel on your transmission output, everything to the clutch bell will spin when you pedal the bike with engine off. If it can't spin, you obviously have a clutch system issue.
