First tubeless set-up. Tape?

So, I have the proper stans tubeless rim tape.

However, I am having a hard time getting full rim-to-tape contact. I and up with gaps where it would ideal to have contact.

The rim (White Industries G25A) is far from a flat surface.

That said, do I need FULL CONTACT or is it fine to simply go over the top of the huge "valley" in the rim?

Huh? What are you talking about? Looks great!

ETA... I'm not sure of the rim orientation for a front asymmetrical rim, or if it's even necessary for a front disk wheel.
Somebody else?

The issue with having the tape not fully in the channel is that you lose the additional space that may be needed to mount a tight tire.

As for rim orientation, the asymmetry is intended help to balance out the L/R spoke angle & tension, mainly on a rear wheel. As long as this particular orientation doesn't overdo this affect it should be fine. Without knowing all the factors, it's hard to judge.

This hub, shimano deore xt, with a symmetrical rim ends up with uneven spoke tension. This asymmetrical rim corrected that.

So, I played around with this (tubeless set-up) pretty much all afternoon. The rear came out great, but the front kept leaking profusely out the valve stem. I got fed up with it and put tubes in. I left in the stans tubeless rim tape.

The tubes should play nicely with the two layers of stans rim tape, right?

Yes, that what I expected with the asymmetrical rim set-up that way, nice tension balance.

When I converted my MTB to tubeless the rim tape looked like the OP's but wouldn't totally seal, air would leak from the valve stem area. I put an extra wrap of Gorilla tape over it and it's good to go. Another advantage of putting Gorilla tape over the stock rim tape is that the bead of the tire is pressed tighter on it so that I was able to get air in the tires with a floor pump. It provided a better seal because of the extra thickness and I didn't have to use a compressor.

I do find cleaning the wheel from all tape residue using a rag with some IPA makes a large difference
