1. First, tighten the ring nut to approximately 52 Nm (5.2 m
kg, 38 ft
lb) with a torque wrench, then
loosen the ring nut completely.
2. Retighten the lower ring nut to specification.
Refer to “INSTALLING THE ENGINE” in chapter 5.
1. Insert the front wheel axle from the right side
and tighten it with the flange bolt from the left
side to 91 Nm (9.1 m

pinch bolt 2, tighten each bolt to
20 Nm (2.0 m
kg, 14 ft

ing temporary tightening.
3. Check that the end face of the axle head and
the end face of the fork side are flush-
mounted. If they are out of alignment, make
sure to fit them by adding the external force
by hand or with a plastic hammer, etc.
If the end face of the axle is not parallel to the
end face of the fork, align them so that one
point of the axle circumference is positioned
on the end face of the fork.
At this stage, it can be accepted if the end
face of the axle becomes partially concave
to the end face of the fork.
