This is very dangerous!The heat damage will be seen inside the clutch drum. Also the metal’s color turns from black to a blue color. Where should you oil the clutch It is behind the snap ring, next to the sprocket teeth at the end of the clutch. There’s an internal bronze bushing behind the snap ring that requires lubrication. It is better to oil the chain at the same time if the chain gets rough from lack of oil.
