I just fitted a new front drive sprocket. When I put the engine in neutral and try to spin the sprocket it feels rachety. Clicky. Notchy. I haven't fitted the chain yet. Is there anything being driven in neutral that will cause this? On any other bike I have ever owned, neutral allows the drive sprocket to spin freely, with just a bit of drag from the bearings. I am crapping myself that this means big big problems.
