BWB, Good evening. On my last right I started seeing my 1125R's oil oil pressure light come on whenever the RPMs dropped from ~6000+ back to idle. It has 3 Qts in it, but I topped it of with another 1/4 - 1/2 a qt just to be sure. The problem persists. As soon as I put some RPMs behind it, ~1750, the light goes away. I am running (and have been running) Motul 300V 10W40. I also recently replaced the ignition cover and in doing so messed with some type sensor that runs through the ignition cover. I have not revisited what that sensor is, but that was over a month ago and the problem only recently presented. I am not a gear head by any means, but I have not researched this problem in depth yet. I am pretty concerned about getting a low oil pressure light, but I don't even know where to start troubleshooting. Does anyone have any suggestions? | ||

The sensor that runs at the top of the ignition cover is the hall effect sensor for the crankshaft. AKA: crank position sensor. You would have removed that if you took off the stator cover. It shouldn't cause your problem. The oil pressure switch isn't on the stator cover. It's located under the oil pump, next to the oil filter mount. You might want to take a look at it's hook up. To verify your oil pressures, you can either replace the switch with another one, or remove the switch and install a testing pressure gauge. the manual lists the following causes for a true low reading for oil pressure: 1. Low oil level. 2. Faulty low oil pressure switch. 3. Worn oil pump gerotor(s). 4. Oil diluted with gas. 5. Open in oiling circuit. | ||

... oil filled with crap that has clogged the pump and filter. Drain some of it and take a look. If it's fine, just pour it back in. | ||

Try dropping the screen (5 bolts) on the right side of the motor, that's where the big stuff accumulates. You need to pull the muffler off to do it. I'd drain the oil and pull out the left side oil filter as well as Jim says. Look for any glitter in the oil for metal shavings. | ||

Another thought. Putting that much oil into the bike could cause the oil to foam, creating cavitation in the oiling system. Oily air bubbles won't give your oil pump what it requires, oil without air. When you change your oil and filter, don't put more than 2.8 quarts back in. | ||

I noticed that you gave the book definition of where the oil pressure sending unit was. It says that it is located under the pump and next to the oil filter mount...However... This seems to suggest that the sensor is on the left side of the engine near the filter(or maybe I'm high, but it's what it sounded like to me). The sensor is actually on the right hand side. |
