The manual for the 748R, which has an Ohlins, says:
Shock absorber adjusters (fig. 18)
The shock absorber has outer adjusters that enable you
to adjust your motorcycle to the load.
The adjuster (1) located on the left side, on the
connection holding the shock absorber to the swingarm,
controls rebound damping.
The adjuster (2) on the shock absorber expansion
reservoir controls compression damping.
Turn the adjusters (1 and 2) clockwise to increase
damping, anticlockwise to reduce it.
turn the adjusters (1 and 2) all the way in (clockwise) then
slacken them 14 clicks.
Two ring nuts (3), 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.
Then tighten or slacken the lower ring nut to increase
or decrease spring preload as required.
