Bike accessories' language is easy to comprehend. Even just by staring at it, you can already grasp the message. Just the mere spark plug color can determine the condition of the bike. Spark plugs change color and that change goes along with its condition. Here are their colors and their corresponding state. :

1. Black. A black dry fluffy colored plug is caused by excessive idling of the bike or by deposits from a carburetor rich with too much gas. Emission of black smoke is a sign of this. On the other hand, black wet glazed plug is caused by the burned oil leaking past the piston rings or valve guides as well as burning in the cylinder.

2. White. This color is caused by the overheating of the engine. Repair of the engine must be reorted to avoid damage to the engine. The plug may turn white when there is leaking crankshafts seals, base or head gasket leaks, no oil, cooling problems, low octane fuel, time not set and too much air/fuel mixture in carburetor.

3. Tan. The engine is normal and the mixture of air/fuel is right when the color of the plug is tan. If a rider intends to replace it, it must be replaced by a plug with the same heat range. New plug have square edges to help the plug fire better.
