Checking and adjusting the steering head bearing *

Check steering head bearing for play periodically. To check, put the
motorcycle on a stand so that the front wheel is off the ground. Now try to
move the fork forward and backward. For readjusting, loosen the five pinch
1
bolts of the top triple clamp and turn steering stem bolt clockwise
there is no more play. Don't tighten the steering stem bolt all the way,
otherwise the bearings will be damaged. With a plastic hammer, lightly tap
on the triple clamp to release tension. Retighten the five pinch bolts to 20 Nm
(15 ft.lb).
