Frankly, as soon as I buy any new bike, taking it apart and regreasing it, is always the first thing I do. Like thirtyfour said, jap bikes hardly have any grease in them. I guess they skimp on the grease to keep their assembly lines cleaner. For instance, the very day I brought home my CRF, I repacked the steering stem bearings, both wheels, and shock linkange with grease. As far as "waterproof grease" that's bull. Grease and water don't mix, therefore all grease is basically waterproof. But some may resist dirt and derbis better than others. Just don't put too much on, as that will just attract dirt and dust.
