Oil Change WR450f 06 model

I have a quick question re: the oil guage on a wr450f 06 model.
This is the second time i have changed the oil and filter and for some reason this time i am not getting an oil reading off the dip stick. I have been on a long ride once since the change and on initially checking the stick it has oil on it but once i stop the bike .. let it rest for about a minute and check it again with a dry dip stick it doesnt show anything on it.
Any thoughts as to why i cant get a reading on the dip stick?
Definately placed just over 1.1lt of oil and have never checked the oil strainers near the drain bolt.

With dry sump type of lubrication, if you wait to long the oil will migrate to the bottom of the ingine case beyond the reach of the dipstick (hence the dry dipstick reading)
I hope this helps.

i took the bike for a 5 min ride through each gear came back and as recommended checked the oil after idle for a couple of minutes.
Still no reading !!!
I am 200% sure i have put the right amount of oil and there is no leaks evident.
I cant see why it wouldnt show on the dipstick !!!!

The book tells you to start the bike let it idle for afew minutes, then shut it off and check it withen a few minutes. I'm on my 5th Yamaha 4-stroke and this is how I've always done it with no problems to thish point.
Start it...let it idle....wait...check level.

Could the oil strainer have anything to do with it? This has never been checked since new but most people say that the strainer is so coarse that you will rarely find anything in it .. hence why i havent check it yet.

Did you bleed the oil system after the oil and filter change? If you do not bleed the system, the oil will not ciculate properly which is bad for the engine and may be causing the issue you are seeing. This is covered in your manual.
Bleeding the oil system? Umm, there is nothing about this in the manual other than the procedure for checking the pressure via the oil gallery bolt. The oil pump isn't a vacuum sealed system like the brakes. There's always going to be air in there bro...SC
