I know Ishould justtake it to the dealer but its such a huge hassle I wondered if there was an easy fix.

Bike is a 2007 Street Glide. The oil pressure gauge continues to show less and less pressure every month. It started out showing 40-50 pounds while cruising around but less than zero pressure at idle (the needle rests on the peg).Now I can be riding along at 3000 RPM and the gauge will drop from 40 to less than zero and sit there.

The dealer checked it out at the 5000 mile service and found nothing wrong withthe gaugebut that is because they didn't bother to let the bike get up to operating temp which is when this starts to happen.

The idiot light has never come on and there is no noise from the lifters so its getting plenty of oil. It's just a problem with the gauge itself. Has anyone seen a problem like this caused by a loose wire or something easy that could be fixed without having to makean appointment, taking time off work, finding a ride home, etc?

 

Sounds like it could be a bad sending unit.

 

Once you absolutely know there is proper oil pressure , the sending unit is usually the problem.
The best way to know "absolutely" is to hook up a mechanical gauge (with the little oil line) and make sure you are ok for pressure.
Then to test the gauge , you can use most any variable resistor device to make the gauge sweep all the way from none to full sweep.
Once the gauge tests ok , the sender is usually the culprit.
This is how we test in the auto repair field.

Bad sending unit or a break in the wiring harness.

 

The dealer did that exact test and confirmed that the pressure was fine so it must be the sending unit. The gauge works just fine when the motor is cold, its not until you have 10 miles or so on it that it starts to act up.

Thank you everyone for your help!
