Got a 2003 Lowrider and was asked to check it over, pulled the aircleaner and started it and bam its an oil transfer pump not a Vtwin engine [URL=http://i1268.photobucket.com/albums/jj574/MMVTwin/VIDEO0288_zps3k1mofcx.mp4][IMG]http://i1268.photobucket.com/albums/jj574/MMVTwin/th_VIDEO0288_zps3k1mofcx.mp4[/img][/URL]
Agree with Walka. Possible cause is the check valve in oil pump stuck or worn. This causes the oil to gather in the crankcase when the bike is not running and when you start the bike it causes crankcase pressure and the only way to relieve that pressure is via the head breathers. Keen to know if you solve the issue.
So I tore into the cam chest and it is trashed, no cam chan tensioners left, can support plate bushing had fallen out and the cank run out is nearly 1mm.
Sumping for sure the case was full and had just filled the motor up and had no where to go
motor is out ready for a major

How the hell can people still keep riding it like that? Maybe it should be WHY would you?
Slipped crank pin Ando?
