    I put a 4-1 Voodoo on about a week ago. Was told that would richen things up so I removed the Y-cover. Stumbled a bit around 5-6K. Read in other places shimming up the Y about 3/16" and adding .025" shims on the needles so tried that. Bike runs fine but I'm still curious what jetting needs to be done if I remove the Y entirely.

    leans it out too much for the needles & mains you have installed

    Removing the Y is too much, you'll need air correctors. If you're going to go that route you might as well get a Morley kit or stage 7 filters. I have a set up I played with, Y remover and the lid hogged out in the shape of the filter. It makes decent mid range, but can't compare to stage 7, or Morley's lid/filter kit.
