I did an oil/filter change just before Biketoberfest. Five days ago my oil light came and stayed on. Well, with BDM having a history of electrical issues, I listened to the heads and felt the fins. All seemed well, but to be safe we rode home. I did my research and concluded the oil pressure switch may have died and/or the ground line had broken. I R&R the switch and started the bike, didnt help. I looked around under the bike and followed the wires, everything seemed to be ok. I took the brand new switch out and noticed no oil had gotten to it, so I took the front rocker cover off and there was oil there. So I began to think that maybe the pressure in the engine moved oil up to the top end but nothing was coming from the sump. I disconnected the supply line from the sump and gently pushed a metal coat hanger in the line. I pressed the rubber tip of my air gun into the oil pressure switch hole and let her rip! Nasty-ass white mucus looking snot came out of my supply line into the catchpan. I wonder how I got water into my oil? I put her all back together and added .6 quart of oil and fired her up. No oil light and no ticking on the top end. All is well again. 1) So where would the water come from? 2) Clean yr pipes once in a while.
