▲ WARNING

You can be injured by scalding fluid or steam if you open lhe radiator cap when the engine is hot.

Do not open the radiator cap when the engine is hot. Wait until engine cools.

Remove the radiator cap.

Check that the engine coolant level is at the bottom of the inlet hole. If not, replenish the radiator with specified engine coolant.

Tighten the radiator cap securely.

CAUTION

Improperly tightening the radiator cap will prevent the cooling system from reaching the specified operating pressure and will cause coolant overflow.

*    This motorcycle does not have an overflow tank ąt the end of

breather hose. Therefore, engine^oof^nt^ęhdriay^cfecrease while riding. Check the engine coolant ieyeieyery time before riding.    \

*    When replenishing emdine^mląątópe surę to use engine coolant mixed with distiiied watśr/at the ratio of 50 : 50. Adding onfy water will dilute engine coolant and it may decrease cooling performance.

*    If the motorcycle is to be exposed to temperatures below -31 X (-24 *F), the percentage of antifreeze should be increased to 55 % or 60 %, according to figurę 1.
