The clutch on my son's KX65 is slipping bad. I've never done a clutch before, but it really doesn't seem to hard. I got the cover off, but my question is how do you remove the main bolt (the service manual calls it the clutch hub nut. The service manual also says to hold the magneto flywheel with a puller tool, but I can't see what this does. I can hold it but the clutch still spins. I've got the spring bolts out, but how the heck do I get the clutch hub nut loose?
