Clean the centrifugal oil filter
Remove the crankcase right-hand cover, as described in
Chapter 1.10, then remove its three retaining screws and
withdraw the filter cover; note the gasket. Carefully clean out
the deposits which will have accumulated around the inner
edge of the unit, noting that these may have become quite
compacted and may need scraping off. Wash each part out
using a lint-free rag soaked in solvent, then dry them off before
refitting the cover. Refit the crankcase cover and refill the
engine to the correct level with the specified oil.

Change the front fork oil
Place the machine on the centre stand then remove the fork
top bolts. Unscrew the drain plug from each fork lower leg and
allow the oil to drain into a suitable container. This is ac-
complished most easily if the legs are attended to in turn. Take
care not to spill any oil onto the brake or tyre. The forks may be
pumped up and down to expel any remaining oil. Refit and
tighten the drain plugs to a torque setting of 0.3 - 0.6 kgf m (2
tighten the fork top bolts to a torque setting of 3.0 - 4.0 kgf m
(22 - 29 Ibf ft).
