Here's a few tips if you're having a go at it. Make sure you use good quality screw drivers that fit the screws and jets properly or you'll damage the heads of them. Leave the throttle cables attached to the carbs or definitely put them back on while the carbs are out of the bike getting them on with the carbs in place is a pain. Getting the carbs into and out of the intake boots is sometimes difficult, a bit of lube like wd40 helps. Don't bother splitting the carbs if it's the first time you've done it, it'll only cause you hassle.
The order it goes in is. Take out the battery. Loosen the screws that hold the air box to the carbs and loosen the bolts that hold the airbox to the frame. Then slide the airbox back and tighten the bolts again to hold the airbox out of the way. Then loosen the intake boot screws all the way. Put your finger on the back of the screw so you know it's out as far as it can go. They have to be all the way out or you'll struggle to get the carbs out. Then push up and down on the carbs until they pop out. Take the top cover of the carbs and take the diaphragm out. Then take the bowl off and take the float and jets out. Give it all a good spray with the carb cleaner and a wipe with a clean cloth. I normally use kitchen roll. Don't spray the diaphragm. You can check it for holes. You can let the jets soak in the carb cleaner if you want. Check that they're all clear. If you've got compressed air given them a blow. If you want you can take out the mixture screws. It's no harm taking note of how many turns out they currently are as someone may have already tuned them so if you know where they are now you can always put them back to that. Be careful if you're turning them back in because if they're already fully seated and you turn them in more you'll damage them. Give them a spray of carb cleaner and a wipe and set them where you want them. Then repeat that for all the other carbs. Put it back together. If you've got a carb balancer you could balance the carbs too. You should be good then.
