VF1000 1984 Almost white plugs?!

I’ve check my plugs and they are almost white!

Might be an air leak but on all the 4 carbs?!?

Performance is good but might be better.

The PO installed a nice air filter on it… not as lean as a K&N but not stock either. I’m rebuilding the carbs so Might go up a point on main jet and shim the needle.

What do you think? What color is yours?

Have you checked the plugs for correct heat range?
