Starting & Stopping the Engine
Always follow the proper starting procedure
described below.
Your CRF can be kickstarted with the transmission
in gear by pulling in the clutch lever before
operating the kickstarter.

The fast idle knob has two functions:
• When pulled out, the fast idle knob assists in
first-time start-up for cold weather starting.
• When pushed in, it acts like an idle adjustment
screw. Refer to Idle Speed Adjustment on
page 58.
Preparation
Make sure that the transmission is in neutral.

should, have your dealer check it for problems.
