When I turn the ignition on all the lights on the instrument panel come on momentarily like they're meant to and then turn off but the oil pressure/coolant temperature warning light remains on. When I start the engine the warning light goes off. The owner's manual states:
This warning light comes on if the engine oil pressure is low or if the coolant temperature is high. If this occurs, stop the engine immediately. The electrical circuit of the warning light can be checked by turning the key to “ON”. The warning light should come on again after going off briefly, and then remain on until the engine is started.
Like I said mine remains solid and doesn't go off briefly like the manual states it should, but does go off when the engine starts.
I can also hear the high pitched whine the bike makes when you first turn the ignition on which usually stops after a second or so, but the whining noise remains constant until I start the engine.
The bike is only a few months old and only has 500 km on it.
Should I just refrain from riding and take it to my local Yamaha dealer?

I haven't checked that the dash lights do that, to be honest. I just check that they don't stay on after starting the engine. On this bike, the ABS light will stay on until rolling a few feet, but all others should be off. As far as the fuel pump, it should only prime for a second or so and shut off until engine is started. If it keeps running, and it didn't do that before, then you might have an issue, like a check valve, bad fuel pressure sensor, or something else. Did you just buy the bike, or it started doing that later? Good luck.
I rang the bike shop today, they said the worry is the fact that the fuel pump is continuously making the noise upon turning the ignition on and said not to ride it for now. One of their senior mechanics is going to get back to me.
What's shit is the fact that my closest Yamaha dealer is 300k away so I can't just drop in and have them have a look, and if the mechanic gets back to me and tells me I need to bring it in then I can't ride all that way without risking damaging the bike.
Sorry to hear. I haven't studied the fuel system on this bike, but I suspect it's a returnless system. If so, my first suspect would be a bad fuel pressure sensor. But it could also be an ECU issue, where it activates the pump a second or so to assure a quick starting. A bad check valve would probably cut the pump and activate it again when pressure drops. I don't know, but it really sucks that we can't know without a freaking dealer. I wonder if the ECU threw a soft code. Is there a way to retrieve Yamaha codes from this bike? I want to be able to read ALL codes, and also to erase them, and monitor other parameters if needed, like with VCDS for Audi/VWs, and FORScan for Fords. Without any computer help, we're sitting ducks, and you have no choice but to take it to a dealer. Sorry to hear that. Oh, and rather than risk getting stranded somewhere, or get the bike damaged by roadside assistance, I'd rent a U-Haul motorcycle trailer ($15/day), and take it in. Please keep us posted, and good luck.
I went for a ride today, once the ignition goes through it's pre-start cycle three lights remain on and solid: Oil, Neutral, ABS. I suspect the OP has no problem with his bike. Ride it, if it has a fueling issue it will eventually let you know. I don't think you actually have any issues.

While I was activating the QS yesterday, also watched the lights, and none extinguished and came back again. Just like Evitzee, all turned on, and then extinguished, except the 3 mentioned by him, which always stayed on. So no issues as far as lights indeed. However, my fuel pump turned off after priming for a second or so. THAT is where the OP has an issue, I think. My main worry would be that the fuel pressure regulator is working properly. With the pump on constantly, fuel pressure could be a lot higher than it needs to be. As far as the pump, my guess is it's working constantly when riding, so that in itself it's not a huge issue IMO. But I'd like to know what's going on in there.
