Hey all. Just changed the oil at 400 miles on my new '02. I did everything by the book and I have done many moto oil changes. Everything is tight and there are no leaks, and the oil level is just over midway between the notches in the sight gauge. But the oil pressure warning light didn't go off after approximately 30 seconds of running the bike at idle. I have never seen this before and am terrified to continue running the bike. Is this normal? I used a 3 1/2" Mobil 1 filter, which I prefilled, and Castrol 20W-50 regular automobile oil.
First, I don't think that's normal... although... it usually does stay on for a few seconds to get the oil circulated.
We've all seen that, you've seen that with the other changes you've done. But 30 secs would have me worried too.
At the risk of some members wanting to shoot me, I never use anything but the oem filters. Something about the amount of flow allowed and 'back pressure', iirc reading some articles about it.
It seems like the only thing that could be causing an issue though, given what you've done? If it were me, I'd change to an oem filter and see if the light goes out?
Forgot to add; it may be the 20w-50. I've heard that if anything, now a days, engines have such tight tolerances, a lighter weight oil is recommended. I put 20w-50 in my (long gone) st1300, it was hard to start (turned slowly) and always seemed to run slower, or differently for sure. And that is one of the things I remember reading about using a thicker weight oil, it doesn't lubricate up at the top as quickly upon start up. So have always just used oem spec. I realize oem spec is indicated in manual and in hot temps use etc etc. But even in Florida during the summer, the 20w-50 seemed too heavy for the ST1300.
