Yamaha WR250FM service manual Do not warm up the engine for extended periods of time

STARTING AND BREAK-IN

GEN INFO

NOTE:

If the engine fails to start by pushing the start switch, release the switch, wait a few seconds, and then try again. Each starting attempt should be as short as possible to preserve the battery. Do not crank the engine more than 10 seconds on any one attempt. If the engine does not start with the starter motor, try using the kickstarter crank.

WARNING

•If the starter motor will not turn when pushing the start switch, stop pushing it immediately and kick start the engine in order to avoid the load on the motor.

•Do not open the throttle while kicking the kickstarter crank. Otherwise, the kick- starter crank may kick back.

7.Return the cold starter knob to its original position and run the engine at 3,000 ~ 5,000 r/min for 1 or 2 minutes.

NOTE:

Since this model is equipped with an accelera- tor pump, if the engine is raced (the throttle opened and closed), the air/fuel mixture will be too rich and the engine may stall. Also unlike a two-stroke engine, this model can idle.

CAUTION:

Do not warm up the engine for extended periods of time.
