Oil light issues

[Sporticus]

I have a 2002 V11 LeMans with around 25K miles. I changed the oil and filter (non-synthetic 20/50) at the end of last season. I’ve ridden it a few times this season and a brand new issue has appeared. The oil light comes on, but only at idle. It flickers around 1500-2000 RPM and comes on solid below 1500 RPM. One correction - it did this just once last season and the problem never reappeared until now. Please tell me I don’t need an oil pump! Thanks for any tips and insight.

Remove the oil filter and check you haven't left the old filter seal installed. Sometimes the old seal comes off the filter and stays stuck to the filter sealing face on the filter housing and then you screw the new filter in place on top of the old seal and you get leakage as you describe at lower RPMs

Thank you Phil. I did some reading here and people talked about dropping the sump pan and cleaning things out. I haven’t dropped the pan in the 10 years I’ve owned it (and never had an issue changing the filter using the correct tool). I order a sump gasket shortly after my original post. I figure it can’t hurt, and will also check for an extra seal.

You don't need to drop the pan just remove the filter and check the sealing face hasn't got a gasket stuck to it.

Sort the oil filter out FIRST . You can stack these seals very easy and miss them until it is too late . when you get satisfied and get done get an  adapter for the oil pressure switch and plumb in a manual or digital gauge and see what you have AFA pressures hot at idle and at 2000-2500 rpm. Digital is cool but needles show fluctuations better.
