Spark Plug Reading

[vijay79]

Hello everybody. I want to know about spark plug reading. I know that spark plug turning white means lean mixture and spark plug getting black is rich mixture. Now my confusion is that after how many kilometres we could check spark plug. For e.g if today new plug is installed in bike, then after how many kilometres running we should check spark plug to know about lean or rich mixture?

If engine running very rich 100KM is enough for reading spark plug. Spark plug reading is very accurate and will give you excellent information on the engine in several factors.
