i have a 2000 road glide efi wich puked oil from filter when ridden at high rpm or for long periods. Harley informed me problem was the oil pump, I rebuilt eng. 5 days ago went with 1550 kit w/cams also upgraded oil pump to solve problem. Rode bike around city eng. performance was great. got it up on interstate to see what she could do 10 miles in eng puked 1 qt of oil from housing, covering new eng. and paint. Oil psi dropped to 5psi, i limped it home but am discouraged problem still exists.oil is pumped to top end to fast and has noware else to go. any ideas would be appreciated. It wasnt over filled and was a Qt and 1/2 low after ride.

 

is there an oil passage block somewhere, or maybe an oil line inverted throught the filter housing, like input/output lines switched?? thats all i can think of without any more deatailed info. good luck.
