Torque your head studs

You will need a torque wrench with a range up to 40 Nm and down to
about 15 Nm with a socket and an extension bar that is long enough to
get the wrench clear of the frame.
Slacken the four bolts by about 1/8 of a turn each. This ensures that they
will not be stuck and will accurately be tightened. 1/8 of a turn is not
enough to break the seal that has been made.
Set the wrench to 20-22 Nm and tighten one nut. Next tighten the
opposite nut. Now do the other two nuts in the same way.
Repeat this with the wrench set to 25-27 Nm.
Now repeat with a setting of 33-35 Nm.

Steering head races

You need to get the front wheel off the ground to check the condition of
the bearings. Head races are checked by raising the front wheel off the
ground and turning the handlebars slowly from side to side. If you notice
a slight 'notchy' feel especially as you pass the straight ahead position,
the bearings are damaged. Next, stand in front of the bike and grip the
bottom of the fork legs. Pull and push, there should be no free play at the
head stock. If there is movement, you need to tighten the races. You
may not be able to feel any free play but as a double check, get
someone else to pull and push whilst you put your finger half on the
bottom yoke and half on the head stock. You will be able to feel the
smallest movement.
Adjusting the head races.
Loosen the pinch bolts on the bottom yoke. Loosen the top nut in the
middle of the top yoke. Under the top yoke there is a castellated ring.
Turn it clockwise to tighten using a C spanner or tap it round with a
hammer and punch. It will not need to be moved much. Do not turn it till
it is tight. The taper roller races are correctly adjusted when there is no
free play. It is very easy to over tighten them and then they will fail quite
quickly.
Tighten them until the forks will not fall from side under their own weight
when you turn them. Now slacken off slightly until they will fall freely.
Now tighten the top nut. You may find that now the races are too tight. If
they are, slacken the top nut, loosen the adjuster a bit and retighten the
top nut. If it feels OK, tap under the bottom yoke (both sides) just to
make sure that the fork legs have moved in the clamps and then tighten
the clamp bolts.
