Replacing the cam lever doesn't always solve the problem. My G5 had the clicks when I got it and still has them, albeit to a lesser degree, after replacing that part. Tearing the machine down was a good learning experience and maybe someday when I'm bored and feel like throwing some more money at the thing, I'll get the gears, tear the thing apart again and install them to see if that helps further. Or I might just leave the thing as-is until it fails and worry about it then. But right now, I'm not bothered enough by the clicks to go through all that.
