Twin Shock Service
Diminishing suspension performance is subtle; deterioration
is gradual so most riders don't notice it happening.
It is the change in damping characteristics
of the oil that will most alert you to the need for a service; the oil will gradually lose its viscocity and
its damping effects will be reduced.
See
Maintenance Article for applicable service periods
and
Damping and Oils for the importance of oil and its usage in suspension performance.
Dismantle and reassemble shocks, check all components for wear
or damage and replace and/or repair where necessary. Re-oil and re-gas.
