Oil Pressure
I have a 99 Electra Glide and after the bike gets fully warmed up and while I am running 80 miles and hourdown the road the oil pressure will drop off to close to zero. Has anyone ever experenced this?

RE: Oil Pressure
How many miles on the bike and what type of oil are you running. You should be at your highest oil presure at freeway speeds,high mileage bikes will have low presure at idle. May have an oil pump problem or just a lot of engine wear.

RE: Oil Pressure
Well the ike has 66000 on it. it runs out great one person said it may be sending unit acting up. From what I know, I have never heared of a sending unit acting up like this. Today when I went for a ride. the first 50 miles I had good oil pressure then when I got back on my bike to come back the pressure went down.

RE: Oil Pressure
Besides the actual oil pump getting worn, or the oil pressure relief valve being stuck (Common) what else is there besides a bushing or two that can contribute to oil pressure loss? The rest of the bearings are needle or roller so I doubt any wear there would cause oil pressure loss.
My money would be oil pump or relief valve. Both pretty easy to check.

RE: Oil Pressure
Your still not providing very useful information. You say oil pressure is good then goes low. What is the oil pressure when cold, idling versus warm idling. What is the pressure at 3000 rpm hot?
Are you saying as the bike gets hotter the oil pressure drops? Or as you get to 80 it drops then you slow down it comes back up? We need more to go on here.
Has this been a gradual drop over years or something that "just" started happening?

RE: Oil Pressure
I know on my bike with 70k on it I'm getting around a 34 PSI reading on my gauge at freeway speeds. At idle when warm around 5 or 6 PSI or so...
