Spark plug read: opinions please

[Guest]

1982 750e CV carbs- How do these look? I think 1&4 may be tad rich, the mix screws are
3-1/4 turns out across the board. The bike starts easy, runs good, and I've dialed out the off-idle stumble.
My question is-should I go leaner with 1&4 or richer with 2&3?

I'm thinking leaner with 1&4, but need a second opinion. Thanks

those plugs are hard to read from that picture; you need a closeup that is full size. Also the place you look is right at the base of the insulator so you probably cant get them all into the same picture.
