OK Gang,

1st - Let me THANK everyone that has posted an oil pressure at idle story, tip, or resolution. I wouldn't have had the knowledge to sort mine out without your help.

2nd - I started a thread on my case, mainly because I had a different solution and outcome than most. After a short test ride at midnight, my light stayed out after start-up, and didn't come back on. Of course, more testing is needed to confirm.

3rd - I have an 03 Justa with the early style oil filter housing. I took photos for a write-up. The short version is my OEM filter cage is there, but the spring was missing. I bought a $2 spring at my local hardware store and modified it to replace the missing one.

4th - I still have unanswered questions after going thru this process.

I will continue this in the next few days as time permits, but it's late now and work is early, Cheers!
