Habits That Could Ruin A Clutch:
1.Driving too slowly: A clutch starts to engage in the Engagement Speed. Driving at full throttle gives the clutch a chance to cool down. Full throttle locks the shoes in the clutch against the drum. When the clutch is not locked up, it will cause tremendous heat which dries up the lubrication in the oil impregnated bushing and damage the clutch.
2.Short stop and go driving: The longer you drive at full throttle the better off it is for the clutch, because it gives it a chance to cool off before the next engagement.
3.Driving with the foot on the brake: Drive with one foot on the pedal, be it the brake or the gas but not to press on both pedals at the same time.
4.Changing the size of the tires: Putting on tires that are larger than what came with the kart will cause premature wear to the clutch.
5.Restrictions: Don't try and reduce a go kart speed by limiting the travel of the gas pedal or by putting a restrictor in the carburetor to limit full rpm. Either of these methods will result in the clutch slipping, which is self destructive.
