Stuck throttle
Sometimes when you try to close the throttle, you may find that it
won’t turn. If this happens when you are slowing for traffic ahead, or
making a turn, you must react quickly to prevent an accident. Here is
what to do:
• immediately operate the engine cutoff switch and pull the clutch.
This disconnects the engine from the rear wheel and keeps you
from speeding up. Once you pull the clutch, you must keep it in
until stopped or the throttle is freed.
• rotate the throttle back and forth several times. If the throttle
cable is stuck, this may free it.
• if you can’t close the throttle, use the motor cut-off switch or the
key to turn off the engine. If your motorcycle does not have a
cut-off switch or the key is on the side of the cycle, stop, then
turn off the engine.
After you have stopped, check the throttle cable carefully to find the
source of the trouble. Make certain the throttle is working freely before
you continue.
