FRONT FORKS
1. ATF is recommended for the front
forks. If slightly stiffer damping charac—
teristics are desired, use SAE 20 or SAE
30 oil.
2. Fork oil should be changed every
3,000 miles or once every 6 months.
3. To drain the fork oil, remove the
drain plug at the lower portion of one of
the fork sliders. Allow the oil to drain for
several minutes into a suitable container,
then pump the forks up and down several
times. After most of the oil is expelled,
turn the forks all the way to the right to
completely drain the right fork leg, or all
the way to the left for the left fork leg.
Check the condition of the drain plug
gasket. Replace it if necessary. Refit the
drain plug and tighten it securely.
4. Repeat the procedure with the other
fork leg. Look at the old oil, if it contains
water or inordinate amounts of dirt, the
fork seals should be replaced.
