Front fork
The oil level is adjustable. A change in the oil level will not affect the lower
part of travel, but it will have an affect on the upper part of travel:
- When the oil level is raised:
The spring effects become more progressive, and the front fork action fe-
els harder at the end of travel.
If the front suspension is making jounce stops, raise the oil level 10 mm.
This increase will provoke a change in upper part of travel of the spring.
- When the oil level is lowered:
The spring effects are less progressive, and the front fork action does not
become hard at the end of travel.
- Change the oil level correctly and the fork will work more at the end of
fork travel.
Oil level adjustment
Adjust the front fork oil level (refer to the maintenance chart).

Troubleshooting Improper Settings
Listed below are some symptoms of improper suspension settings and the
most likely means of correcting them.
The proper settings can be achieved by applying the information in this chap-
ter in a scientific manner. Take time to think about the changes you believe
necessary, check them against the symptoms and cures described here, and
make the changes in small increments, and take notes on the changes and
their effects.
