b. Adjust Fully Closed Throttle ([fig. 43]). See that there is about 1 inch distance between end of control wire housing and throttle lever when in fully closed position, so that housing end does not interfere with forward movement of throttle lever. If adjustment of control wire housing is necessary, refer to paragraph [101]. Proceed with closed throttle adjustment.
(1) Loosen control wire clamp screw in connector block.
(2) Turn right handle bar grip outward as far as it will go: then turn it inward slightly. Holding throttle grip in this position, move throttle lever forward against its stop (closed position) and secure control wire in connector block with clamp screw. Check closing of throttle after tightening control wire set screw. If necessary, reset the control wire in the connector block until throttle is closed with full outward grip movement.
c. Adjust Fully Open Throttle ([fig. 44]). Follow instructions under step b above, then:
(1) Turn right handle bar grip inward as far as it will go and see that throttle lever is against its stop in fully open position. If throttle does not open fully when grip is turned inward, reset the control wire in the connector block to correct the adjustment.
