    Thankyou @Tinkicker for your sage thoughts and advice.

    Next thing: I let the bike idle for a while then went to drain the oil, I removed the oil tank cap and saw that the oil level had risen considerably, is this a sign that I’ve overfilled it or something else?

    I’m gonna measure how much came out and compare it to the recommended oil fill amount.

    I’ve measured 3.1 litres of old oil & reckon on another 100mm of spillages & remains left in the container which equals 3.2 litres … Haynes manual says 2 litres then warm up then add another 300mm, so 900mm overfilled 🤦🏼‍♂️
    Could this be as easy as filling with the right quantity & spec of oil?

    Also, does it have the correct oil? 

    Now this is a VERY good question and I can’t remember what the hell I put in & I took all the old oil & bottles to the tip.

    It should be 15/50 semi synth, I may have put 10/40 semi synth in  by mistake.

    Gonna drain the oil anyway.

    Would you recommend a flush before refilling properly? If so what make?

    Dunno if that engine has a pressure relief valve, but if it does, and the pressure is too high, it may be jammed partially open.

    I’m hoping this is the issue.

    There are 2 ‘check’ valves behind the oil filter that I will have a look at when I drain the oil

    We come back to your oil pressure readings.  As said earlier.  45 psi at idle cold seems very high for a roller bearing engine.  Do you know the correct spec from the manual? You need reliable info to troubleshoot.

    2. I now know this is a dry sump engine.  It has two oil pumps, one gives main pressure and the other is a scavenger that returns oil to the tank.  When you look in the tank, can you see oil returning?  If so, i doubt your engine will blow up and it is a sensor problem.

    Again another good point.

    I looked in the tank & couldn’t see the oil from the scavenge pipe going into the tank and the oil in the tank doesn’t drop when the engines running, but I removed the scavenge pipe from the tank, cranked the engine over and it spewed out oil, so unless it is blocked in the tank I don’t think this is the problem, although I will remove the tank and ensure it’s all clear.

    You say you replaced the oil sensor for a fiver.  Is it the correct, brand new, genuine BMW part for that specific engine?  If not that is almost certainly the problem the pressure rating will be wrong.  If you bought the bike secondhand, someone before you may have fitted the wrong part and you just replaced it like for like.  A fiver for a genuine BMW oil sensor seems extremely inexpensive.

    Good point!
    However I found the BMW part number for the sensor & it’s equivalent OEM part number ( it’s used on a lot of vehicles, not just motorbikes ) and got a NOS part from a guy who was selling off his old stuff after closing his shop down.

    The part from BMW is £20 so not a big difference & a pretty std BMW mark up.

    I tested the one that came out & it seemed ok.

    Sorry, the bike is a 2020 Yamaha Tracer 900 GT

    Silly question, you did put the front wheel on the right way round so the ABS sensor ring is next to the sensor? Not the other side

    Having reread your earlier post.  Assuming the oil pressure problem is a new issue..

     

     

     "& align the water pump drive, the gear change shaft, the solid oil bypass pipe & finally the clutch actuation mechanism, been trying for hours without success but think I’ve fond the reason:"

     

    Having looked at parts drawings for this pipe ( without success) I also note that the crank looks to be a pressed together roller bearing type.  So scratch worn crank bearings. A roller bearing crank will tolerate zero oil pressure as long as there is flow.  So it is not as dire as you thought.

     

    However 45psi at idle cold is not usual for a roller bearing engine engine either.  They usually run around 8 psi.  

     

    As said, if this probem occurred after you had the covers off, it is most likely something you did wrong.

    You could be very right, but I’m hoping not - as doing that all again fills me with dread

    You need to check pressure at operating temp.  Typically, an oil pressure switch is set to operate at 8 - 10 psi.

     

    Cold testing tells you nothing.

     

    I let it idle until the fan came on and by then the pressure was almost non existent, but the oil pumps can be ruled out as a likely issue right? 

  11. I have a new slightly baffling issue with this bike that some of you might be able to give some guidance on, or take the piss .. it’s fine by me.

     

    So the oil pressure light has started flickering when the engine is warm but goes out when I Increase the revs, after a while it stays on at idle.

    I went to the owners forums and the consensus was a failed oil pressure switch ( a common problem) I removed the switch (B’stard of a job), tested it, seemed fine but I fitted a new one for £5 for purposes of elimination … however the problem still exists and worried that the oil pumps might be knackered I purchased an oil pressure gauge kit which I fitted to the oil pressure switch boss, it would seem that the pumps are fine with a pressure of 45PSI at cold idle & 85PSI at 4500 revs. 
    So the question is.. WTF? 🤷🏻‍♂️
    Another thing I’ve noticed is that although the oil isn’t contaminated it is very black and it was only changed a couple of hundred miles ago when I fitted a new water pump.

    Yesterday in an owners forum I happened to mention that I was thinking of changing the end canof my exhaust.  I would leave the hideous cat unit but swap out the end can. The responses I got made me somewhat irked. Basically I got called every kind of idiot known to man for even thinking about messing up this finely tuned instrument  blah blah blah. I make no claims to being any kind of expert in this field so if its a potentially damaging thing to do then obviously I won't. If its harmless then I will. Any opinions on the forum? Not that I'll necessarily listen to them mind!

    It’s your bike, do wtf you like to it, nobody else’s business.

    Quite like the Piston Club myself. Enjoyed looking at your pics of bikes too until the last one of some hideous French monstrosity. 

    Quite like the French monstrosity myself, liked the young lady driving it even more 😍

    So not much has changed vis a vis Scottish police then. My fortunately few encounters with them have been uniformly unpleasant. 

    Especially when they discover you are English, found out through bitter experience.
