1.Remove the steering link from the fork. Refer to CON-

NECTING/REMOVING STEERING LINK TO/FROM FORK in this procedure of the manual.

2.Rotate the steering link adjustment nuts until they are against the steering link as shown in FIGURE 2. DO NOT tighten

3.Perform the following steps. Refer to CHART A for an example of thread calculation.

A.Count the number of drive arm threads and steer- ing pin threads between the rod ends and the steering link.

B.Divide the number of threads determined in STEP A in half.

C.Rotate the steering pin rod end and the steering link until only the number of threads determined STEP B are showing at each end.

4.Securely tighten both steering link adjustment nuts against the steering link.

5.Connect the steering pin to the fork. Refer to CON-
