Basic Maintenance Procedures
The engine in your go-kart has been designed to run on any gasoline with a pump octane rating of
87 or higher. Most service stations will display the octane rating above each pump. Although it is
not required, Monster Moto recommends using premium gasoline with a 92 octane rating or higher
to ensure maximum performance and reliability. This engine is not designed to work with ethanol
blended fuel.
Use of a lower octane gasoline can cause pre-detonation in the engine. When this occurs, you will
hear a persistent “pinging” or “spark knock” which, if severe, can cause engine damage. It is how-
ever no cause for concern if you hear light pinging while the engine is under hard acceleration,
such as climbing up a hill. If pinging occurs under normal load and a steady engine speed, switch
brands of gasoline and be sure you are using the proper octane rating. Use of unleaded fuel is
recommended because it produces fewer engine deposits and extends the life of the engine and
exhaust components.
Never use stale or contaminated gasoline. Never use gasoline that has been mixed with oil. Avoid
getting dust, dirt and water into the fuel tank.
Fuel Recommendation
Refueling Procedure
1. Twist the fuel tank cap counter-clockwise and remove the cap from the tank.
2. Using a funnel, add fuel to the tank until the level reaches about 2 inches from the top of the
tank.
3. Twist the fuel cap clockwise until it is securely tight.
Gasoline is highly flammable and explosive.
You can be burned or seriously injured when handling gasoline.
Always stop the engine before refueling. Only handle gasoline
outdoors. Clean all spills immediately.
