Ive just added some boyeson reeds to my bike and WOW! What a difference! the bike starts runs and pulls so much better. Anyway back to the point. I checked the colour of the plug before i started so that i could tell if the bike was running any richer.
The plug was black and looked very oily before I added the reeds and after I fitted the reeds, the plug is still the same colour.
I am checking the plug by running the bike for say 10 mins and then killing the engine. I am not reving the engine but simply letting it idle.
Is this the right method to check the plug?
The plug that I am using is the one that came with the bike which is a NGK B7ES. The plug looks in good condition. I note that the standard should be a NGK BP7ES.
So I am wondering is the fouling of the plug down to the model? Or should i change something on the carb???
