the engine and requires very sophisti-
cated adjustment. Therefore, most

to a Yamaha dealer, who has the
necessary professional knowledge
and experience. The adjustment
described in the following section,
however, may be serviced by the
owner as part of routine mainte-
nance.

factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.

squeeze the excess oil out.

The sponge material should be wet
but not dripping.
