4.Checkfor correct tension onthe forward drive belt by taking two measurements of the cable spring, as follows:

a. With the Forward Clutch Bail (Y,Fig. 2- 6) in an open (released)position, measure

the length of the cable spring (W) from the outermost coil to the outermost coil.

b. Squeezethe ForwardClutch Bailagainst the handlebar(see Fig. 2-7) and re-mea- sure the spring length. The belt tension is correct if this second measurementis be-

tween 1/16" to 3/16" longer than the first measurement. If so, turn the hex nut (Z, Fig. 2-7) tightly against the cable adjuster
