Take the carbs off and cut the battery box off the aribox. Replace every screw on the carb bowls and caps with M4xwhatever (I don't remember what length, check the link in my sig to see what length...) It's a lot of work for the one time that you do it, but it makes taking the carbs out every time afterwards much easier.
Just do it. Trust me.
Then cut open your intake lid and rejet as needed.
free small performance boost.
as for not damaging the diaphragms, I just hold it in with a finger and flip the carbs upside down (not an option if you don't remove the carbs) to get the needles out. When there's washers on your needles, you can leave the carbs on the bike and just use a magnet to get the washers and needles out of the diaphragm out without even touching them.
