E Shock absorber adjusters Rear shock absorbers feature spring preload, rebound and compression adjustment. The adjuster (1, fig. 26) on the shock absorber expansion reservoir - LH side of the frame - controls compression damping. The adjuster (2, fig. 25) on the left of the connection holding the shock absorber to the swingarm controls rebound damping. Turn the adjusters (1 and 2) clockwise to increase damping. Two ring nuts (3, fig. 26) located on the top section of the shock absorber are used to adjust the outer spring preload. To change spring preload, slacken the upper ring nut. Once preload has been set as required, tighten the upper ring nut. Then tighten or slacken the lower ring to increase or decrease spring preload. Warning Use a specific pin wrench to turn the preload adjusting nut. Be careful when turning the nut with the wrench, as the pin may slip out of the ring nut recess and you may hurt your hand hitting motorcycle parts. Warning The shock absorber is filled with gas under pressure and may cause severe damage if taken apart by unskilled persons. 2 fig. 25 3 1 fig. 26 30
