frame race and bearings.
Alternatively, place a box under the forks to support.
Assemble the two top cover tubes and handlebar lug, connect the
damper rods to the top bolts.
Engage the top bolts as far as possible, then release the clamp screws.
Firmly tighten the top bolts then the clamp screw. (See 'Special pre-
cautions').
Adjust the steering head bearings and fill oil to each fork tube.
Steering head adjustment. The steering head frame races are of the
floating self-aligning type and have spherical seats. Therefore they do not
fit tightly in the head lug.
Occasionally test the steering head for correct adjustment by exerting
pressure upwards from the extreme ends of the handlebars.
It is particularly important that the adjustment is tested after the first
100 miles because of the initial settling down that always occurs in that
period.
Should any shake be apparent, adjust the steering head bearings.
Adjust steering head bearings by: Jacking up the front of the machine so
that all weight is taken off the front wheel. (A box under each footrest
serves that purpose).
Slacken the two fork crown Allen screws.
Slacken the domed nut at top of the steering column.
Screw down the nut underneath the domed nut a little at a time and
while doing so, test the head assembly for slackness by placing the fingers
over the gap between handlebar lug and frame top lug, at the same time
exerting upward pressure by lifting from the front edge of the front mud-
guard. Tested in this? manner the slightest slackness is discernible.
