Which K&N pod/cone filters for the 81 GPz550 with stock carbs?

Looks like I bought a set of filters that are way way too large for the 22 carbs. Does anyone know what the go-to K&N pod is for these tiny carbs?

Wish there was a cheaper alternative to the K&Ns.

After many years of using different pods, the Emgo style pods are my favorite. They are only about $7 each. No oil or cleaner to buy which adds a other 20 to 40 bucks to the k&ns. If you are in a dry dusty environment, though, the stock airbox with stock paper filter might be better for the motor.

39mm. You will need to rejet, or at least bump up the needle.
