So I went out riding yesterday when I got back the bike was smoking from oil dripping on the header.......cleaned the bike off and the only place i could see oil dripping from was the bottom of the left side radiator. Now I know that I blew the decompression plug out but when i started the bike and let it run for a minute the oil was still dripping off the radiator and not spraying from the decompression plug. and there isn't oil in the coolant. Im scratching my head

The missing decompression plug is the cause.

The oil blows out of the decomp. hole,hits the rad and runs down the tubes and pools on the bottom tank of the rad,then drips down onto the exhaust.
