4. Squeeze wheel drive control lever (X,
Figure 5-1) against handlebar.
Measure between the coiled ends of
the stretched spring (W, Figure 5-4),
making sure you measure between the
same coils used in step 3. The spring
length should now measure 1/2"
(13mm) longer than the measurement
taken in step 3. If it does not, loosen
jam nut (Y, Figure 5-4) and turn ad-
juster (Z, Figure 5-4) to increase or
decrease the spring length. (1-1/4
turns of the adjuster equals 1/16"
[1.5mm] of spring extension.) Hold
the adjuster and tighten the jam nut
(Y) when the correct spring length is
obtained. Re-check measurements
and adjust if needed.
If after completing this adjustment the
wheels do not drive adequately, refer
to Drive Disc Clearance Adjustment in
this Section. Then repeat this
adjustment.
