・Always use new gaskets and packings. And check those parts, to be reused, for wear and damage. If you find worn or damaged parts, replace

them with new ones.

・Never look into the carburetor's intake pipe carelessly when the engine is running. Flames could spurt by the spitting-back of gasoline or backfire,

which involves danger.

following cautions.

CAUTION

・Always start the engine in a well-ventilated place, and do not turn on the engine in an airtight place.

・When you notice something unusual with your motorcycle while riding, immediately stop riding and park your motorcycle in a safe place to check

with new ones. (The continued use of these damaged parts as they are could lead to accidents.)

・As gasoline is highly flammable, never place it close to fire. Make sure that nothing flammable is near the gasoline. Since vaporized accumulation of

gasoline is at high risk of explosion, work in a well-ventilated place. (Otherwise it may cause a fire.)
