Shock absorbers should also be adjusted for warm weather driving. Turning the square end of the needle valve changes the adjustment. The average adjustment for rear shock absorbers during warm weather is made as follows:
Screw needle valve in until it seats, then back valve off 1⁄4 turn. For front shock absorbers back valve off 3⁄8 of a turn.
These settings are of course only approximate, as due to the individual characteristics of each instrument it is difficult to lay down any hard and fast rules as to exact settings.
