Hi brothers
My bike has 100,000 km. The front exhaust valve stem is white and the valve is black...the rear exhaust valve stem is a good black dry carbon. The pipes front and back have a black coating like its running rich. The bike runs fine...idles correct...no backfire...I just am a little concerned maybe running the bike without baffles might be the cause of the white valve stem.
