When you start your mini moto the clutch spins as the engine ticks over . The clutch is engaged when you pull back on the throttle. The increase in speed of revolution of the clutch makes the clutch expand and grip the inside of the clutch bell which turns the sprock
et that drives the back wheel of your pocket bike.The clutch can be set up in different ways depending on the type of performance that you want from your minimoto. Adjustable clutches are not standard on mini moto's but an after market Polani or Blata style adjustable clutch can be used in your new mini moto. These allow the rider to adjust the mini moto's set up in according to their preference. Setting the clutch to engage too late when the engine has built up too much power may cause the clutch to slip and never fully engage. This can result in excessive wearing. However setting the clutch to engage too early, before the power has built up in the engine can cause your pocket bike to 'bog down', resulting in slow acceleration. The perfect set up is to get the clutch to engage just as the engine has built enough power to rocket the mini moto away, but without making the clutch slip, this is achievable through trial and error.
