AVS2 carb tuning. Anyone with experience out there?

The hardest thing to except is the smooth transition between the primaries and the secondarys. when it bogs, and it try to put you face in the windshield. Then it comes back on you get slammed into the seat. Feels GRATE!!!

When it is working right you don't feel the secondaries and thing they are not working.
Your butt odometer(how it feels to you ) will lie to you every day and twice on Sunday.
If you feel the secondaries come in it was falling off and loosen you up in the seat before the eng was able to overcome the extra air of the secondaries and push you back in to the seat.

That was the hardest thing to accept and overcome..... "Smooth is Fast". feeling the secondarys coming on is slow. Your butt will lie to you every time and tell you that it is not so.
In fact i never got over it. Keep opening the air door sooner until i felt the secondarys coming on and my et would slow.

As i just couldn't get my mind to accept that......... i when to a double pumper and never looked back.
