Oil pressure switch
« on: 09 January 2019, 01:23:30 PM »
Twice in the last two days, my oil light has come on, spookily in exactly the same place on my daily commute.
After around a mile, I come to a T junction, and while idling, the light comes on. Revving the engine doesn't kame it go out, and when I pull away and lean left and right it still satys on. Stopping, switching off the ignition and then back on makes it go out, but I'm thinking the switch might be on its' way out.

Bike has 62000 miles and yes the oil is topped up.

How do you check your oil level?

Checked with the window, on centre stand on level ground, when cold.

Centre stand, level ground, but you need to start the engine and let it run for about a minute, then switch off and  it’ll settle in about 30 seconds, that’s your level.
Sounds like your oil is too low.

The light is just for oil level, it’s not a pressure reading.

Rather than faffing about running the engine for a specific length of time and then letting it stand for a specific length of time, I prefer to just check it when cold... mine likes it filled to the top of the window, any less than that and it gives the dreaded red light.

I don’t even have that luxury any more. My window isn’t see through.
2.8 litres in with a new filter does me until the next change.

I have found the difference between it staying off and coming on is about the same amount as an egg cup.  :woot

At some points in my ownership, the level has fallen so you couldn't see it in the window, no light came on.
This is midway between the two lines and the light comes on, strange.

Didn't come on today, perhaps it was too cold for the light to make an appearance.  :D

Next oil change I'll take the sender out and check it over, until then, a bit of insulating tape should sort out the distracting lamp.

Midway between the two lines with a cold engine switched off means not enough oil.

Go on then, I'll bite.
Midway between the two lines that Yamaha cast into the casing is not correct?
Has anyone told Yamaha this?
Is there a recall to get replacement recalibrated casings?

Read the manual, and it will tell you run the engine before checking the level, as i said earlier.

I think the reason is this. If the engine is cold - that means that all the oil that can flow back down has done so. After a short warm up and a couple of mins wait - there is still oil around all the parts that has yet to drip back down into the sump window area. I does seem a bit rubbish to have to read the level via this procedure as it just says a few mins after warm up but the longer you warm it the hotter the oil which will more readily/ quickly drip back down to the window area then the longer you leave it the more oil will drip down so there are too many variables. I would be much better if the procedure was from cold - cutting out all those variables.This would mean that the window would have to be higher as when cold all the oil that will do has dripped down and is near or above the top. I wonder if the read from warm procedure is just because they could not fit a window higher.

The reason is so you don't need to wait an hour after running the engine to check the oil level.

How about this. If it's stone cold the oil level should be at or near the top mark. If it's stopped + a few minutes it should be somewhere between top and bottom marks  :D

That sounds like the most logical reason to me.

Maybe a slightly bigger viewing window would cater for everyone.
I do mine from the bottle now anyway, no window for me, and as long as there's no leaks then i don't need to do anything until i change it again, which i personally prefer to do every 4000 miles, even though it's recommended at every 6000 miles. Works for me, and the bike doesn't complain.  :lol

The most logical way - if the window would allow is for it to be from cold which would be BEFORE you rode it or started it. Rather than start it - warm it - stop it- wait a few mins - look at it - start it and ride.

As i said, a bigger, or better still maybe an upright rectangular window similar to what you get on the back of oil containers, rather than round, so you can see all levels from cold, or when warm would make far more sense.
Once you know how much oil you have in there, after a change for example, then you can see both cold or warm levels then know if it’s right or wrong at a glance.
I must say though that the window on these sumps are pretty shite.......especially my one.  :lol

The manual has to give a method that's accurate and covers all scenarios. They can't say check it from cold because a cold bike that was park two hours ago is going to show a different level to a cold bike that was parked a year ago even if they have the same amount of oil in them.   The only way to cover all scenarios is to say start it up, turn it off, let it settle and then check it. They can't even give exact times to start it up because the bike could be parked in -10 weather or it could be in 40 degree weather so the viscosity of the oil would be totally different. Saying start it for two minutes and turn it off for a minute then check wouldn't work. The way they say to do it is the only way that covers all scenarios which is what the manual has to do.
I printed out DUDE'S instructions...even on paper they are pretty confusing...Has he been INGESTING some MIND ALTERING substance......???
