bleed the front fork as follows.
1. Elevate the front wheel by placing
a suitable stand under the engine.
NOTE:
When bleeding the front fork, there
should be no weight on the front end of

CAUTION:
Never attempt to turn an adjusting

listed below.
NOTE:
The spring preload setting is deter-

load; the longer distance A is, the lower
the spring preload.
