I brought my 90RR back to life after sitting out in driveway for almost three years. A couple of shots of starting fluid did it. All the dash lights remained on as it idled. I added a can of MarvelMysteryOil in the crankcase, and a can of B12 Chemtool to the1/4 full gas tank. I let it idle for20 more minutes disconnected and reconnected the battery. All the dash lights are good off now, but the Low Oil Pressure light remains on.
Can anyone provide some advice on how to diagnose the problem? Bad oil pump? Is it safe to continue to let the engine idle with the light on that perhapsrecirculatingoil additive would resolve the problem?

Thanks!

Do an crank case flush ASAP, and get all the sludge build up out of your engine and then see if the light stays on.
If you want help with this, get back to me.
