I have an 1100 1981 wing . have had the oil pump out 4 times and cannot get oil pressure. have tried many things . anyone ran into this? thanks ken Noonday,texas

have you done anything that would block the oil passeges in the block? are you sure its the pump and not the sending unit? are you checking the pump pressure at the proper rpm

I found the trouble and You are right on it , had a blockage in nthe oil pickup screen. It is fine now. Thanks for the help, ken
