I initially removed the emissions parts, but my carbs were dirty and needed to be cleaned. I put 142/42 in there at first, but after a year decided it was just too rich and wasn't necessary, so I went down to 135/38. Stock is 132/38, so I went one size up on the main jet, left the pilot stock. I also run with one shim under the needle, which can help a bit with throttle response on the low end. If your carbs are clean and the bike runs well, earshave isn't really necessary. i viewed the earshave more of an ease-of-maintenance mod than a performance mod, although it vastly helped my performance because of how clogged my jets were and how dirty my carbs were.

Even with the earshave the carbs are a PITA to remove, but a whole heck of a lot easier than with the stock airbox in place.

BTW, removing the emissions equipment without doing the earshave is referred to "coastering/coasterizing" or "marbling" on this forum, that may help you in finding a good guide to assist you in what you want to do.
