should always point straight back from the
steering post.
3. Place a chalk mark on the center line of the front
tires approximately 10 (25.4 cm) from the floor or
as close to the hub/axle center line as possible.
NOTE: It is important that the height of both
marks be equally positioned in order to get an
accurate measurement.
4. Measure the distance between the marks and
record the measurement. Call this measurement
“A”.
5. Rotate the tires 180 by movingvehicle forwardor
backward. Position chalk marks facing rearward,
even with the hub/axle centerline.
6. Again measure the distance between the marks
and record. Call this measurement “B”. Subtract
measurement “B from measurement “A”. The
difference between measurements “A” and “B” is
the vehicle toe alignment. The recommended
vehicle toe tolerance is 1/8 to 1/4 (.3 to .6 cm)
toe out. This means the measurement at thefront
of the tire (A) is 1/8 to1/4 (.3 to .6 cm) wider than
the measurement at the rear (B)
TOE ALIGNMENT
ADJUSTMENT
If toe alignment is incorrect, measure the distance
between vehicle center and each wheel. This will tell
you which tie rod needs adjusting. NOTE: Be sure
handlebars are straight ahead before determining
which tie rod(s) need adjustment.
CAUTION: During tie rod adjustment, it is very
important that the following precautions be taken
when tightening tie rod end jam nuts. If the rod end
is positioned incorrectly it will not pivot, and may
break.

To adjust toe alignment:
S Hold tie rod end to keep it from rotating.
S Loosenjam nuts at bothendof thetierod.
S Shorten or lengthen the tie rod until
alignment is as required to achieve the
proper toe setting as specified in
Method 1 or Method 2.
S IMPORTANT: When tightening the tie
rod end jam nuts, the rod ends must be
held parallel to prevent rod end damage
and premature wear. Damage may not
be immediately apparent if done
incorrectly. See illustration 2.
S After alignment is complete, torque jam
nuts to 12-14 ft. lbs. (16-19 Nm).
