See-through viewing window for oil is not see-through anymore - kriszzzz - 24-10-15
Hi, I have a bit of an issue as I can't see how much oil I have in the engine. The viewing window has just gone dark grey over the years, I can't see through it now. I have recently changed oil & filter and thought that the window should clear up with having the new oil in, but it is still dark. I put the recommended amount of oil in it, so the oil level should be OK, but obviously, I want to be sure that the level is ok.
Any advice?

When checking oil levels you need to start the engine and let it run for a minute, switch off, then watch it settle.
That'll be the correct level once it settles.
I personally have it about two thirds up between the lower/upper case markings.

I have to use a decent torch to see mine. Tilting the bike slowly left and right may help you spot the level, though that is really a two-person job.
You may be able to improve the view by taking the cover off and cleaning the inside of the window with a cotton bud. It can be done without losing oil if the bike's on the side stand, but you'll probably need a new gasket.

I believe Yamaha fits a low level not low pressure warning light so if you do have a light on at anytime its not likely to result in engine damage.
As for your issue you could always drill a hole in the sight glass at the maximum level..................... :b

This just happened with my bike a few days ago
I had an oil leak from the front of my oil filter, one of those K&N ones with the shit non sized nut on that doesn't fit any socket. I think a stone may have hit around the outer disc which is joined to the nut causing it to leak.
Anyway, on refilling with oil i could not see ANYTHING in the oil window.
I used a torch, and kept pouring the oil, waiting to see something, but nothing, to the point i now realised i must have put too much in anyway. Started the engine as well, but the window just looks clear.
So as i'd started the engine i knew the new filter had oil in, so i emptied the sump completely then refilled it with 2.7 litres to be safe.
I've never ever needed to top up in between oil changes before, and i change it every 4000 miles, so i'm just gonna have to hope the levels are good for the duration as there's feck all i can do about the window.
On a side note, i mangled the head of my old original sump plug a while back so bought one of those replacement ones on Ebay with the magnet in the middle.
These have about half the amount of threads as an OEM one which i did find a bit odd, then found out the hard way that because of this it pulled about 3 threads out of my sump casing, and i was only doing it up by hand with a spanner. :'(
So i would suggest avoid buying one of those if you ever need one.
[size=1em]I then paid a tenner for some fancy bolt with an expandable rubber ring in the middle of the thread, but afterwards found that, rather surprisingly, OEM [/size][size=1em]bolts are only £5.35 delivered on the AJ Sutton site. [/size][size=1em]All sorted now though and my new bolt nipped up okay fortunately with no feel or sign of thread issues.[/size] :woot

1/4 cap of Windolene next oil change should do the trick.

What?
I don't think i like the idea of putting a non oily substance in my sump.

I think he is just joking, I hope so anyway! I mean why use expensive windolene when a bit of vinegar in water works just as well.

The weird thing about it is that the colour of the glass really looks like it's full of clear fresh oil, it's not foggy or black, it's really strange.
