Normal Maintenance

Normal scheduled maintenance for a pit bike can extend the lifecycle of your new toy considerably. From oil changes to replacing air filters on a timely basis, investing time in completing some of the suggested maintenance tips below can significantly improve performance and enjoyment of any pit bike. All the information provided below is a simple starting point of a normal maintenance program, but does not guarantee that mechanical breakdown won't occur. If you have additional questions about the service tips listed below, feel free to contact our customer service department.

Understanding the Break-In Period

The break in period of a pit bike is typically your first three rides which individually last no longer than 10 minutes for each ride. Once this process is complete, we recommend making a few changes to your pit bike and completing a few recommended maintenance check-ups to ensure all moving parts are property tightened and ready for full use.

  1. Tighten the spokes. To do this, from the valve stem, tighten every third spoke. Please refer to the above image for location of the spokes.
  2. Tighten your chain. After your first 3 initial rides, your chain is going to stretch. It is important to keep your chain tightened to the appropriate tension to avoid chain malfunction while riding. You will also want to check your chain every time before you ride. For more info, check out our how to video below.
  3. Replace your Spark Plugs. Even though the spark plugs that come with our bikes are decent, you will always want to upgrade your spark plug to a NKG Spark Plug (Part number CR7HSA Plug BX/10NKG). Doing this will greatly improve your horsepower and the performance of the bike with little cost to you.
  4. Apply fork oil to the front forks. Typically after the first rides, front forks can be made stiffer by adding fork oil. To do this, visit your local pit bike dealer or contact Killer Motorsports to inquire as to which brand or type of fork oil is best for your specific pit bike.
  5. Adjust your rear shock for comfort. The rear shock can be loosened or tightened at the rear spring. Although not required, it's a good idea to understand this fact so you can fine-tune your suspension to match your comfort level and riding preference.
  6. Adjust handlebars for safety. The handlebars are also adjustable so that you can pick a riding position that makes it easier to steer your pit bike but also for easy application of throttle and brake handles for safety.
  7. Fill up gas with Premium Unleaded Gasoline. Pit bikes sold from Killer Motorsports are performance engines that require a cleaner grade of gasoline. It's recommended to run a minimum of 89 octane to 91 octane unleaded gasoline. It is NOT recommended to add fuel additives or performance boosters as that can lead to premature wear and tear of valve train components. DO NOT USE MIXED GASOLINE typically used for two-stroke motors.
