i would personally run either 33mm or 35mm pwk. more common carb and more people run them. that way youll have more people who can help you get them dialed in. for your application id say 33mm would be best. should be able to find some fairly cheap but youll also need intakes for them and prolly a new air filter setup.
my brothers bike did this. we were hillclimbing and he got stopped on a hill. bike rolled back a little ways and he ended up busting the kickstart gear. it was pretty messy.
any machine shop should be able to bore your carbs.
91banshee, stock carbs are actually really good carbs. and ive heard from several different builders that stock carbs will outflow a stock stroke ported motor and will work even on a 4mm motor. ive actually seen a very hard running 4mm stock cylinder motor running stock carbs.
