Tenere 2018 XT660z wont start after valve adjustment

Gday

Well I knew i shouldnt have done it! After a big ride in the desert i decided to pull off the taank pull out the fuel pump to see how much crud was in it. The bike is a 2010 and im the 3rd owner so thinking it has been used in the bush alot there would be crud! Nothing in it!!
so back on with the fule pump and though i would try my hand at valve adjustments, i got all the specs from my dealer and i thought all went well....
1st mistake the old decimal point on the mm guages i have.. bugga off to the shop now the correct sizes.
Re set the valve, put it all back to gather and bugga wont start.
It will turn over no problem and maybe fire a bit has run for about 2 -3 seconds with no real revs.

Things i have checked over:
Fuel: checked the pump is running on start up and yes i can hear fuel being sucked up.
disconnected both hoses and tested the pump in to a cup, yes fuel comes out.
Spark: Brand new iridium plug and checked gap, and the bike fires every so often?
Valves: Recked numerous times and went up a measure to see if it made any affect.

So i have made a stuff up somewhere, unfortunately i didn't run the bike after doing the tank so i cant exclude that item completely. But fuel in tank and pump runs.
I have all the marks lined up correctly prior to checking

can anyone shed any light on this problem before i blow another gasket!

Oh and i don't have a back wheel on it as i fractured a Excel rim on the trip..

cheers Crunchie

Are you absolutely positive you had the "I" mark on the rotor lined up with the notch on the inspection cap hole and not part of the "H" mark that comes before it? If you set the valves by one of the vertical lines on the "H" by mistake then the valve clearance will be non-existent at TDC and the either the inlets or exhausts (depending on the stroke) will not close fully causing a compression leak and a rough/non-running scenario.

Talking

Pleiades and Crew

Well after sleepless nights worrying, I came to the conclusion it must be fuel, last night was my last go . I pulled out the fuel pump separated the two sections and noticed a small black O ring the is on the joining tube for the two half of the carrier.
Looked at the O ring thought it didn't look seated properly so pulled it out and out pops a small flat disk with a nipple!.
Reset the O ring on the smaller tuber and "snapped in" the disk, put it all back to gather popped the tank on.....
First press of the starter off she went!!

So for anyone pulling a pump apart we aware of the O ring !

I slept well last night!, now to get a back wheel!
