OIL REPLACEMENT
• Remove the rear shock absorber unit from the frame ( 6-
33), and then clean and dry it.
• Remove the spring from the rear shock absorber unit. ( 6-
34)
NOTE:
* Inspect the rear shock absorber unit for oil leakage.
* Be sure to fully turn the rebound damping force adjusting screw
counterclockwise, so that the rear suspension oil can be poured
out easily.
• Remove the valve cap, and then press the valve with a screw-
driver to bleed out nitrogen gas.
* Releasing high pressure gas from the rear shock ab-
sorber unit can be hazardous. Never perform any ser-
vicing until the nitrogen gas pressure has been re-
leased from the rear shock absorber unit.
* When releasing the gas pressure, place a rag over the
gas valve and use the tip of a screwdriver to press the
valve. Do not use your finger to depress the gas valve,
and be sure to direct the valve away from your face
and body.
* Be sure to always wear eye protection when perform-
ing this procedure.
• Remove the compression adjuster assembly from the rear
shock absorber using special tool.
