Air Valve Secondaries
I thought the air valves were adjustable by bending the little tangs. Maybe you can turn the "630"s into 600s,580s,or 550s,lol.

Ahhhhhh, no... that would be a TQ as the AVS is a positive stop on the upper body IIRC. The spring loaded secondary door can be wound really tight, but ......
Dang! It’s been a while since I owned one. Love the AVS!

If you tighten the spring the air valve, it shuts when there's not enough air to hold it open, like a choke it sucks more fuel.

I don’t know if the spring is capable of holding the door closed at high rpm. Middle rpm... maybe. It is a good thought though. I didn’t think of that.
At least in that way the secondary system totally shuts down until a higher rpm comes back into play.
