Default '05 KX250F Timing Marks, Compression?

My 2005 KX250F has been hard to start so I decided to check the valve lash. Sure enough it was about 0.000mm. I reset the valve lash to specs and put it back together.

There are three Timing Marks; First one is all alone, second and third are about 5 degrees apart. I spun my crank counter clockwise and lined up the third mark. Dots on the cam sprockets faced up and out no problem. Exhaust cam lobe was at about 10 o'clock, intake cam lobe was at about 2 0'clock. 28 timing chain pins between outer most dots on cam sprockets. Torqued cam caps down to specs.

Bike will not fire.

Plenty of spark and fuel. It won't even sputter when I give it a shot of starter fluid which makes me think my timing is off.

It seems like I hear two stories when it comes to Timing Marks. One version is to use the third timing mark, the second is to split the difference between the second and third timing marks. Which is true?

What is the Compression spec? I realize the bike has an "auto-matic" compression release on the exhaust cam. I think I can disengage this with my finger with the valve cover off if I am careful.

You need to use the mark on the right side, of the two next to each other. Hope this helps. Cam gears CAN spin on the cams causing cams to be out of time even when the marks on the gears are perfect. Lobes on cams should be point up and away from each other the same amount.
