QGIVE SAFETY THE RIGHT OF WAY

Motorcycles are fascinating vehicles, which can give you an unsurpassed feeling of power and freedom. However, they also impose certain limits, which you must accept; even the best motorcycle does not ignore the laws of physics.

Regular care and maintenance are essential for preserving your motorcycle’s value and operating condition. Moreover, what is true for the motorcycle is also true for the rider: good performance depends on being in good shape. Riding under the influence of medication, drugs and alcohol is, of course, out of the question. Motorcycle riders - more than car drivers - must always be at their mental and physical best. Under the influence of even small amounts of alcohol, there is a tendency to take dangerous risks.

Protective clothing is as essential for the motorcycle rider as seat belts are for car drivers and passengers. Always wear a complete motorcycle suit (whether made of leather or tear-resistant synthetic materials with protectors), sturdy boots, motorcycle gloves and a properly fitting helmet. Optimum protective wear, however, should not encourage carelessness. Though full-cov- erage helmets and suits, in particular, create an illusion of total safety and protection, motorcyclists will always be vulnerable. Riders who lack critical self-control run the risk of going too fast and are apt to take chances. This is even more dangerous in wet weather. The good motorcyclist rides safely, predictably and defensively - avoiding all dangers, including those caused by others.

Enjoy your ride!

The negative pressure fuel cock supplies fuel from the tank to the carburetor while filtering it also.

The fuel cock has the following three positions:

ON

With the lever in this position, fuel flows if the engine is running, but stops if the engine is not running.

This indicates reserve. If you run out of fuel while riding, move the lever to “PRI”, start the engine, then move the lever to “RES”. FILL THE TANK AT THE FIRST OPPORTUNITY. BE SURE TO MOVE THE LEVER TO “ON” AFTER REFUELING.

NOTE:

The fuel cock operates on vacuum from the engine when set at “ON” or “RES”. If the line connecting the cock to the carburetor intake manifold is not connected or has a leak, the cock will not function properly.

PRE-OPERATION CHECKS

Owners are personally responsible for their vehicle’s condition. Your motorcycle’s vital functions can start to deteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any damage, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual inspection, you check the following points before each ride.

EAU00340

PRE-OPERATION CHECK LIST

	ITEM		CHECKS	PAGE

NOTE:

Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be accomplished in a very short time; and the added safety it assures is more than worth the time involved.

w

If any item in the Pre-Operation Check is not working properly, have it inspected and repaired before operating the motorcycle.
