Coarse Adjustment: If the fine adjustment is not sufficient,
remove the throttle cable from the throttle body and unscrew the
retaining nut B to increase the free-play. Tighten the retaining nut
B after the adjustment.
After all adjustments, verify the throttle can turn smoothly from full
open to full close at any handlebar position. If there is any
impediment to turning the throttle smoothly, adjust or replace the
throttle or cable.
Warning: Too much or too little throttle free-play or
operating the motorcycle with throttle impediments is very
dangerous and can result in sudden acceleration and/or loss of
control of the vehicle.
Brake System
The front brake is hydraulic disk type, and the rear brake is cable-
actuated drum type. Inspect the brake system prior to each ride.
Properly functioning brake systems are vitally important to your
personal safety. Check for fluid leaks, fluid level, brake shoe
wear, and rotor and drum condition. Also check lever free play
frequently.
Front Brake
Pull the brake lever lightly until you feel tension, then check the
lever free-play. If the brake lever has no free-play or is too loose,
there is a potential brake system fault. Inspect brake system
thoroughly.
