Checking and adjusting the steering head bearing *

Check steering head bearing for play periodically. To check, put motorcycle
on the stand so that the front wheel is off the ground. Now try to move the
fork forward and backward. For readjusting, loosen the three clamp screws

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 rap
on the triple clamp to release tension. Retighten the three clamp screws to
20 Nm.
