2005 R6. In the middle of valve adjustment. I have a question about the timing.
Manual says the exhaust and intake cams should line up perfectly with cylinder head at TDC. But my intake line is slightly dipped. I have to look over into the head to see it. But if I move 1 tooth over, it will be too much above the cylinder head line. Am I doing something wrong?

U do nothing wrong, just keep going.

And the Manual doesn't say "perfectly"

You might have a slight amount of chain stretch, but not enough that I would have any concern about.

But to be honest, from your photos: Your trigger wheel looks like it isn’t lined up exactly at the crankcase seam and the EX cam line is slightly higher than the head. It looks to me that if you rotate the crank just a hair more so it lines up with the case split, the cams will be perfectly aligned. I’d bet you are right on the money.

Chain stretch makes sense.
I really hope the stretch isn't too bad. I'm not really up for changing the chain and sprockets right now.
The camera angle is a little off, but the rotor T mark is much better aligned in reality.
