The mains aren't triggered by RPM alone. Throttle position has a huge roll in it. If you are WOT at 2500 rpms coming out of a turn, your mains are flowing. I had a long conversation with a forum member and we talked about the 2 progression holes in the idle circuit. You can see them if you shine a light down the venturi and take out the inspection plug just below the mixture screw. You should only see 1. If you see 2 then your throttle plate is closed to far. The problem is if you set the idle screw to only show one hole, I am turning some serious RPM's, not just idling. I think I am going to try the smaller air correctors and see what happens. Tonight I raised my idle to 1100 and I backed the mixture screw out almost 1 turn. I will see what happens tomorrow.
