    Cleaned carbs now have a hanging rpm issue

    I'm at 4.5 turns out on the mixture screws and the bike starts better now. Still have the hanging rpm. I synced carbs before i reassembled everything. I put the filters back on. Im around 1000 feet elevation. The jetting is stock. Whats good for checking air leaks?
