Look for wires, bolts and other fasteners that may have come loose on previous rides. Inspect the drive chain, throttle and brakes for proper adjustment and operation. Check the engine oil level in the oil tank. Check fuel level and inspect for fuel leaks. (Remember, you can ride further in 1 hour than you can walk back in 1 day!)

11. WARM UP your body with some exercises before riding. This helps to make you alert and prevent cramping and other discomfort.

Control Features

	Engine Stop Switch
The	stop

switch is a red colored rocker switch located on the left-hand handle bar.

To start and run the engine, this switch must be placed in the on, “O”, position.

The vehicle is also equipped with a safety brake switch which will prevent the engine from starting until the parking brake is engaged.

To stop your engine, place the switch to the stop, “X”, position.

In the stop, “X”, position the ignition system is grounded preventing the spark plug from firing.

This switch can also be used as a safety or emergency stop switch.

Manual choke lever (9)

All Viper models are equipped with a manually operated carburetor choke system. This choke is operated by the lever at the bottom of the left hand control switch.

When first starting the engine,(cold start), place the lever in the full left position, (Choke closed or on) As the engine warms return the lever to the full right position. (Choke open or off).

Throttle lever

The throttle lever is located on the right-hand handle bar below the grip. To operate the throttle lever, place your right thumb on the lever and press forward to increase your speed. To decrease your speed, reduce your pressure on the lever and the spring tension will automatically reduce your speed.

The travel of the throttle lever is controlled by the throttle stop bolt.

As your operator gains more experience, you can increase the throttle travel to allow for additional speed to be obtained.

To increase the throttle’s travel, thus increasing the maximum speed, turn the throttle stop bolt counter clockwise. To decrease the throttle’s travel, thus decreasing the maximum speed, turn the throttle stop bolt clockwise.

The throttle cable should be adjusted so there is 2mm, (1/8”) free travel at the lever before the throttle starts to open.

Front and Rear Brakes

This vehicle is equipped with dual front mechanical drum brakes and a rear hydraulic disc brake. (Viper 70 Viper 90 & Viper 90R) (Viper 50M is equipped with rear hydraulic disc brake only)

The front brakes are controlled by the long brake lever on the right-handle bar.

The rear brake is controlled by the long lever on the left-handle bar.

The rear brake is the primary stopping brake on your vehicle. Using the rear brake to stop your vehicle will prevent steering control loss.

Use your front and rear brakes in combination to control your speed while descending a grade. Use caution not to apply too much pressure to your front brakes so that the wheels lock up, stop turning, and causing a loss of steering control. If the front wheels lock up, and stop turning, lightly reduce the pressure on the front brake lever until they unlock and start to turn.

Parking Brake

The front brake lever has a button located at the pivot point to lock the brake in the, “O”, on position. This should be engaged as a parking brake whenever the vehicle is not in operation.

This feature must be engaged in order to start the engine. The brake lever has a safety switch built in to prevent the engine from starting while the brake is disengaged.

If your engine fails to start, ensure that the engine stop switch is in the on, “O”, position and that the parking brake is engaged.

Safety Tether Switch

The Viper 50M and Viper 70 models are equipped with a safety tether switch. The switch is located on the left hand side of the handlebars. The switch cap must be fully engaged for the vehicle to start and run.

The cap is tied to a tether that should be worn around the rider wrist. In case of an emergency a simple pull on the tether will disengage the switch and stop the engine.

Remote Stop/Start Switch

The Viper 50M come equipped with a remote Stop/Start key ring switch. (This feature is an optional kit for the Viper 70 & Viper 90. A remote Stop Only kit is optional for the Viper 90R).

The remote switch has two buttons, a Stop button which will stop the engine when pressed. The effective range of the switch is 30 feet unobstructed.

Page 10

Once the unit has been stopped with the remote switch you must press the run button in order for the unit to be restarted. This action resets the remote receiver on the unit.

The unit may also be started remotely by pressing both the Stop & Run buttons together.

Safety Note: Always test the remote switch before beginning a riding session. The remote switch is operated by a battery which should be replace one a year. You can obtain a replacement battery at your local department store.

Fuel Tank

The fuel tank fill cap is located on top of the

unit just ahead of the seat. The cap contains a vent to prevent a vacuum from forming in the tank as fuel is used. The vent tube must be attached to the cap and inserted in the vent tube holder hole while operating the unit. The fuel cap vent and vent tube must be clean and clear of obstructions for the unit to operate normally. You can check the vent and vent tube by blowing air through the tube. If you can not blow through the vent tube and cap you must clean the vent and tube or replace them.

Every time you refuel your unit, check the rubber seal inside the cap for cuts, tears and dirt. Clean or replace the seal if it becomes worn or torn. The seal must be in good condition to insure a proper seal of the cap to the tank to prevent fuel spills. DO NOT allow

dirt or other debris to enter the tank when refueling.

Replace the cap if damaged or if it will not seal to the tank.

Tighten the cap snugly, being careful not to over tighten. Over tightening the cap can cause damage to the cap or seal.

The fuel tank capacity is 4.5 liters, 1.2 gal, including a reserve of 0.8 liters, 0.2 gal.

Use unleaded automobile gasoline with an octane level of 91 or higher.

NEVER REFUEL YOUR ATV when the engine is HOT. Wait 30 minutes after turning off the unit before refueling. Spilling fuel on a HOT engine could cause a fire. Wipe up any fuel spills before re-starting.

Fuel Valve

The unit is equipped with a three way fuel valve located on the left side of the unit just below the seat.

The valve has three settings; “OFF”, “ON” and “RES”. With the valve in the “OFF” position fuel is held in the tank and is prevented from flowing to the carburetor. The valve should be placed in the “OFF” position whenever the unit is not being operated. Place the valve in the “ON” position for normal operation of the unit. This allows fuel to flow to the carburetor for normal operating. The “RES” position allows fuel to flow from the small
