Spring Tension Inspection

Since the spring becomes shorter as it weakens, check
its free length [A] to determine its condition.
If the spring of either rear shock absorber is shorter than
the service limit, it must be replaced. If the length of re-
placement spring and that of the remaining spring vary
greatly, the remaing spring should also be replaced in or-
der to keep the rear shock absorbers balanced of motor-
cycle stability.
