Suzuki C50 Oil Pressure Light?

Any Suzuki authorities out there? I have an '05 C50 Boulevard. Purchased new. Creeping up on 43K. About 50 miles past its 2,000 mile oil change. It'll get done tomorrow. Oil level is almost over full on the sight window.

Hot day, today, in upstate NY... around 90 degrees. Let it sit idling in the driveway after my ride until the cooling fan turned off. The red Check Engine Light started flickering along with that little oil-can symbol on the speedometer. That light means oil pressure, coolant temperature, or a fuel injection problem, depending on the LCD symbol accompanying it.

Looks like I was getting a genuine "low oil pressure" warning. That's new. Does this model have a history of pressure sensor problems? Is there any Suzuki pressure gauge I can install in place of the idiot light? OR, is it actual mechanical wear and I'm going to be looking into a replacement motorcycle soon?

Back-ground information. Oil changes done pretty much on time, but it gets a chance to use all of its meager 50hp often. Coolant changed for the first time last winter and rocker arm clearances checked 7,500 miles too late (last year). They still didn't need any adjustments. So, good on some maintenance and lacking on some.
