You need to rejet to #170 jetting and add two washers too your needles on each carb slide.
You can drill the jets up you currently have with a #51 drill bit but do it slowly better by hand even. The washers you'll have to call R@D about or a motorcylce shop to get the correct size but you have to add atleast two to help open the needle up more so you don't have a lean spot around 6000 rpm.

I would do jets...
Never drill in my opinion....Just because the possibility of running a cross hatch in there or could even be off by .5mm would be enough to make a jetting night mare.
Plus unless you can measure each jet acurately then how would you know they are the same.
If one jet flows just even a little more fuel then the other then that cylinder will always be rich on carbs you cant adjust.
but that is Just My opinion...

Just to let you know that adding only f/a's wont do anything for you performance wise. I very much doubt you will be able to tell.
