I know when reeds are delaminating they say to replace them. My issue is I have an early 2000's ktm and I bought new reeds but they don't sit flush against the cage at all. I would like to avoid spending $140 on Delta 3 reeds so I put the original worn reeds back in the cage and they sit flush. Should I run them like this since not much light is passing through?

Replace those before they get sucked into your top end…dont get hung up on the new reeds nit sitting totally flat, Vforce states this is not really a big deal…
How poorly do the new reeds sit? Can you flip them over and see if it improves it? I wouldn't be concerned about a small gap, the crank pressure will seal them shut.
this is how the new reeds sit. Yes I flipped them over as well
I would just use them, will probably run fine. If it runs like dogshit you'll know the problem and can complain to dealer to trade em out.

If you can pull a vacuum on the reed cage with your mouth/other and the reeds seal, you're likely good, BUT if you do see fraying/chipping --- EVEN IF THEY ARE SEALING --- as @sandman768 says, replace them before they end up in your top end.
I remember watching my Dad test parts of all kinds like this. Taste the oil, grease, stethoscopes to listen to running parts (for bearing issues, etc.) --- he was quite adept at engine development and parts assessment. He no like-y chipped or delaminating parts. 🤣
