Drain
the fork oil by removing the drain bolt ( fig
1 )with the allen wrench. The oil will
only trickle out at first, but will flow quickly once the fill screw (fig
2 ) is removed with the screwdriver.
Re-install the drain screw.
Measure
out 0.485 litres of 10w fork oil and use the syringe ( fig
3 - I bought this one in the Auto parts section
of WalMart) to fill up the fork. Make sure that the syringe is held
tightly over the fill hole and inject the fork oil. After injecting
the oil, while still holding the syringe tightly against the fill hole,
withdraw the plunger to remove the build up of air caused by the displacement
of the new fork oil. This will help prevent the fork from burping
the oil back out of the fork.
Re-install the filler screw and repeat with the other fork.
In the case the handlebars prevent direct access
to the filler hole from the syringe, a piece of plastic tubing can be placed
over the end of the syringe to gain easier access to the filler hole.
