The shop manual tells you to remove the fork legs to pack your steering head bearings. But what do they know? Ok Ok, they know a lot, but that doesn't mean you can't take a shortcut here and there. If you know your bearings are in decent shape, theres no reason to go through all the hassle of removing the fork legs. Simply start by removing the top triple clamp pinch bolts that hold the legs on.
First we'll have a little disclaimer. If you work on your own equipment, you are responsible for it. Don't come whining to me if you break something. If you aren't comfortable with your mechanical skills, then don't practice on your motorcycle... practice on somebody else's. (just kidding)
