It is pretty easy to adjust your steering head bearings and I have always done it by feel. Check on you tube for a video (or get a manual) but it is basically the same on any bike.
- Loosen the steering stem nut on top of the triple clamp (may have to remove handlebars to get at it)
- Loosen upper triple clamp fork tube bolts.
- Under the upper triple clamp is a collar that is used to set bearing preload - it should have notches in it. I use a punch and light hammer to tap it clockwise (tighten). It won't take much. You want to adjust that collar so you remove the play but the front end will move side to side freely and without any notchiness (too tight).
Note: When you are checking for play in the steering head, make sure you grab the fork tubes above the sliders.
- After you remove the play, tight up the steering stem nut, then the triple clamp fork tube bolts (use proper torque). re-instal handlebars and done.
