You should probably get a service manual.
As I recall: Remove seat, gas tank, side covers and brackets, and plastic things in front corners of frame. Take off rubber intake thingy and slide out air filter cover toward the left side (it's a ***** because of the flap in front). Loosen metal intake housing plate, rotate and remove intake horns being careful not to bend the horns or drop screws down carb throats. Slide plate out.
All four carbs come off as one assembly. There are four rubber tubes connecting it to the engine. Loosen the hose clamps on the tubes and gently pry the carb assembly up. Find safe points on the carbs to pry where you won't break anything, and be gentle. If it hasn't come off before it will take some going from corner to corner till it comes out of the rubber tubes.
You can clean the jets without disassembling the "quad pack".
I put a little oil on the tubes to reassemble. Getting the horns back in is a bit tricky. The plate goes on loose, then they slide into the carbs and rotate as I recall. Good luck
