Question about 2007 Yamaha Ybr 125
I never heard of a brown plug. It should be black, blue, crud, or oil. The mix will turn the plug blue from being too rich, burning hot, and of course the black from soot or carbon, from being lean, Then the oil you don't want to see, but changing plugs is a must. I get great performance from Autolite plugs in my bike. 10 times better than champions. Clean the air filter while you are at it. Hope this helps.
