Default hillbilly 650 oil pressure

Alright, now that the electrical system is working again, i found that the oil light is on. The oil level is where it should be, there is a bit of oil leaking from the cylinder head gasket.

The haynes manual i bought doesnt really give me much in the way of trouble shooting, it just says that if the oil light is on to fix the problem before riding...right...so, any ideas?

There really isnt much more, i havnt taken a look at the pump yet, i am just looking for some troubleshooting tips.

The bike is running pretty good, no out of the ordinary engine noise, doesnt seem to be overheating, has decent performance, but that light stays on.

There is an oil pressure sensor, and something is screwing it up. The easy thing to do (given your previous electrical issues) is to check the wiring from the oil light down to the sensor. If that is sound, I'd suspect the sensor itself may be plugged or not functioning in some way, but that's the limit of my knowledge.

You'll know if the oil pressure is actually bad because the engine will grenade in a couple of minutes. If you've been riding it any length of time then it's the sensor or wiring not the pump.

Do you hear any loud whiring noises or tapping/clacking noises after it warms up? If not, it's just a bad sensor, since the CB650 was based on the indestructable CB550 four. Takes a lot to blow those old Hondas up. Also, when hot does it start right back up again, or kinda drag along before firing up?

ive really only ridden it a short distance, as i have stressed, it is a backwoods special and ive spent alot of time trying to clean up some of the mess it was in when i got it(for very cheap, might i add).

It doesnt tap, crack, clank, crank, or anything like that. The only real engine noise is a quiet chain sound. It starts fine, no hesitation.
