Setting of spring after replacement

As the front fork setting can be easily affected by
rear suspension, take care so that the machine
front and rear are balanced (in position, etc.)
when setting the front fork.
1. Use of soft spring
Generally a soft spring gives a soft riding
feeling. Rebound damping tends to become
stronger and the front fork may sink deeply
over a series of gaps.
To set a soft spring:
9Change the rebound damping.
Turn out one or two clicks.
9Change the compression damping.
Turn in one or two clicks.
