Ok, bike started making a little noise Saturday while riding, so for giggles, I checked the valve clearance, needed to be done anyway. Then I pulled the clutch out to see if maybe the key and gear were loose, is there anyway to tell without taking the complete side cover off of the case? Or do I have to pull it all down and pull the gear off? The gear doesn't seem to move or have any play but it is not possible to see the ballancer(?) gear with the cover and other stuff still on. This motor was replaced last Sept. and I am thinking this is what happened to it the first time. What are the possibilities of Yamaha puting an '01 crank in it when they rebuilt it? As usual, thanks for any help given.
