When the bike is idling the clutch makes noise like a chatter sound. The clutch works well with no problems. If I pull the clutch lever in the chatter goes away a little, it quiets down. If I rev the bike up a little the clutch noise goes away all the way and it sounds like normal, in other words it makes no noise.
How serious is this? How quickly do I have to fix it? I don't have a lot of money at the moment. I'm wondering if I should do the job myself but I don't have a clutch holder tool.
