well here goes I had to change the breather gear (to my surprise it was made of plastic ) another story, replaced it and cleaned everything, put it back together. when I started the bike no oil pressure. I found the supply to the pump was clogged at the tank. I flushed the tank and pulled the pump and cleaned everything thoroughly. put it back together started it up YEA good oil pressure. drove it a mile or 2 turned it off went to go for a ride a little later went a mile or so an no oil pressure again so I replaced the pump with a high volume S&S. still no pressure I checked the drive keys ( all 3) breather timing screen for the top end. and there is good flow to the pump. nothing out of the pump. any ideas guys cause im stumped
