Exclamation Low Oil Pressure

I bought my wife a 390 Duke and when wee went to pick it up she got 3 miles away from the shop when a "low Oil Pressure" error came on. We took it straight back. They changed the oil and oil filter took it out and it erred again. They tested the oil pressure with a true pressure gauge and the pressure was good. So they said the oil pressure switch was bad. We waited two days for a new switch to come in and we finally took the bike home. My wife rode it for a week then low and behold it came on again, two days in a row. Back to the shop they are getting another switch thinking it may fix the issue. It is only coming on for a few minutes now instead of staying on, but its very scary. Any one else have this issue? The technical rep in USA said its been happening.

I picked up my 390 with 50 miles on the clock last week (UK bike).

The "Low Oil Pressure" light comes on after approx 35 to 40 minutes of riding. The warning light and message then comes off and on intermittently.

I've checked the oil level and it seems the dealer has filled the oil above the MAX indicator and I've drained it back down to a maximum level. The "Low Oil Pressure" still comes on after 35 minutes of ridding but is no less frequent.

I'm just going to wait until the first service to see what can be done.

I love the bike but its annoying seeing such a critical warning light come on and off on a brand new purchase.

I've got the same "Low Oil Pressure" warning appearing on mine too.

Happened last weekend on a spirited run up the Lakes, just need to pull a finger out and phone the local dealership up and see what they say.

My dealer said over the phone that it's only a real concern if the light stays on constantly.

Given the intermittent nature of the warning, its probably a batch of faulty sensors.

ktmdude, your dealer is probably right. If the oil pressure stays on constantly without popping up intermittently, then you truly have an issue. But then I guess on (any) new bike it ain't supposed to be happening, as you've pointed out, perhaps a faulty batch.

Upon asking, my dealer here advised me, if you keep seeing LOW OIL PRESS warnings, and you are on the far side, park your bike and check your oil level, if it's on the right level, pressure shouldn't be problem, perhaps it can be just a sensor issue. Eaton pumps last a life time, so as long as the oil level is pukka there's nothing to worry.

If you keep seeing a constant oil pressure warning (rather than an intermittent) one after a mile or so after you first cranked your bike, then it's wise to get it checked as ASAP.

Just my two cents when asked about the question to my dealership here.

Cheers!

I agree with B7ACKTHORN. If the intermittent low pressure indication were the result of an actual, motor-threatening low oil pressure condition, your motor would almost certainly have seized by now. Very likely it's just a maladjusted sensor.
