Sorry for my first real post for being a question but here goes:

I bought a salvaged 2003 600rr that was a theft recovery that the insurance company totaled out. I rebuilt it got it salvaged inspected and on the road. Ive put about a thousand miles on it so far and it is way faster that my old (very old) 500 ninja!

The oil pressure light came on after about 200 miles of total riding or so. I assumed that the oil had just expanded tot he point where it was "too full" and the bike was warning me. The reason i thought this is that day was the first time it was about freezing. I changed the oil and filter with amsoil 10w-40 and a honda filter when i rebuilt the bike.

The oil level is good and the bike runs fine with no problems doesnt overheat etc. I just replaced the oil pressure switch today and the light is still on. As far as i can tell the wire hasnt been broken or anything.

So where can i get a pressure gauge and/or what signs of low oil pressure should i look for. My dad is a mechanic and he rode the bike and looked it over quick and said he didnt see anything amiss and the bike runs fine.

THANKS!

Are you getting any mil codes, where the light flashes when the key is on?

No codes just a solid light all the time.

Does the oil pressure unit output a high voltage? Light could i apply 12v to the end of the led just to test if the wire is good all the way up? I cant find any good info in the service manual.

Sorry to thread jack, but I'm having a similar problem with my bike at the moment. I was out at a track day a couple weekends ago, and that red light came on for me as well. It wasn't constant though which I don't seem to understand. It didn't come on until later in the day, and it only comes on after riding for a little while. I just ignored it at the track day (probably not a good idea, but the bike was running fine). Since then, I changed the oil, would go riding, and the light would come on maybe after riding for an hour.

I'm hoping whatever information you find out, can help me as well. I asked someone about it, and he told me the pressure screw might be loose or something. It seemed just fine to me.

I just found this searching through some threads. Maybe this might help.

I'm going to go check this out on mine.

Check your oil level. It needs to be inbetween the lines in the site window. When the bike is off and oil has settled. Could be too high, could be too low. T

+1 on potential for to high oil level, would explain why it only happens after a period of time while riding, as the oil starts to foam from getting beat to death by the crank.

My oil level is perfect right between the lines. I even tried adding more and taking some out no changes. Someone once told me that guy on the track just put a piece of tape over the light because its always on.

Any idea where to find a pressure guage, the honda part number in the service manual is a dead end.

That light will only come on like that for low oil pressure, not high oil level. First thing you will notice when you have to much oil in there is very bad sounds and possibly a con rod out the side of the block... you would have to put a fair bit in though.

And if you want to check the wiring take it from open circuit to ground...

Im gonna try calling up the local dealership to find pressure gauge.

You would think if i had low oil pressure something would be wrong IE temp, power, etc.

If you had low oil pressure, yes the light would come on. Along with this you should also see a rise in running temp of the bike, the clutch will start to feel sticky and you will probably also start to smell it burning.

Check the wiring for the light first.

Thats what i figured but i picked up a cheap oil pressure tester and my pressure was dead on. I also tried shorting the oil pressure wire to ground and nothing happened so I think ive narrowed down the problem to a short somewhere in the cluster.

Look for the problem between there and the cluster first... it could also be that you oil pressure switch has gone short... does the oil light go out when you unplug the switch?

No the light does not go out... ever. I did replace the switch with a new one though, so either the wire or the cluster has to have a short somewhere I guess.

Yep...

Just remove the plug from the back of the gauges and measure the resistance of the blue / red wire to ground, if its short then repeat the process at the grey plug under the left hand ram air cover, this will tell you what side the short is on.

If it comes up as being between the grey plug and the sensor (the more likely case I think) then cut the wire just down from the grey plug and again just down from the sensor and run a new piece of wire... if the short is on the gauge side the solution is the same.

If the wire is open to ground, pull you gauges apart and have a look for any corrosion or foreign objects before replacing them.
