Just a little FYI to save some agro!

A lot of people have mentioned stripping the heads of screws in the carbs and I haven't seen this mentioned anywhere yet so...

Japanese bikes use JIS not ISO/DIN fasteners especially on the carbs, so get yourself a good JIS screwdriver and it'll save you some headaches!

i use stainless steel m5 socket head allen bolts on every set of carbs i work on from the gsxr4
