Order the shim kit when you order the new pilots. A set of four is like $2. That "plane out" feeling is a lean mid range (more than likely). Put a shim on the stock needles and the bike will pull hard through the midrange as well. I run two shims, but I'm more open on both ends (FREAK and drag pipe fishtails).
BTW- it would be a good idea to balance the carbs again after all this is done.
Did the RTV help/ work?
