the length ofthecable spring (W) from the
outermost coil to the outermost coil.
b. Squeezethe ForwardClutch Bailagainst
the handlebar(seeFig. 2-7) and re-mea-
surethe spring length. The belt tension is
correct if this second measurementis be-
tween 1/16"to 3/16" longer thanthe first
measurement.If so, turn the hex nut (Z,
Fig. 2-7) tightly against the cableadjuster
(X) while preventingthe cableadjuster
