I found it a complete pig to get them out and back in for the simple reason they have to be manipulated through the frame space which is too small to just draw them out. Putting them back in, the rubbers to the cylinders were so tough and inflexible (probably age) that it was very hard to get both carbs seated back up properly. Overall though, from memory, ignoring these 2 bits, its really a matter of
Remove fuel hose and vacuum hose from tank. Disconnect fuel sender lead (else you'll rip it of when you lift the tank )
Undo fairing side bolts and pull fairing away from tank
Unbolt and slide tank back - lift off - If full of fuel, you might find this heavy! Either do it on empty or remove the fuel by putting a container under the removed fuel hose and suck (or apply gentle suction) to the petrol tap vacuum hose. This will turn on the tap and the fuel will come out.
Undo hoses from air filter to carbs
remove air filter and all hoses (note where they all go, though most are sat at their natural positions, so it's not too hard, if a bit fiddly to get them back on)
Remove throttle cable and choke plungers. The choke plugers were another pig - Just so hard to get in, screw out and back. 20 minutes with sore fingers should do it.
With the rubber cylinder boots between the cyls and the carbs loosened, the carbs just pull off (easier said than done on my bike).
Probably missed something, but that's about it.
I did this because the bike had been standing for a _long_ time and carbs were totally gunked. First try I just removed them, doused in carb cleaner and re-installed. Didn't help. Whilst you have them off, do it properly. I stripped them completely down, cooked them in 'citra clean' cleaner in a big pot and it ate the varnish right out of it all. All the jets were in some way blocked. Cleaning and a very fine needle made it so I could see through them again. All put back together and I recently synced them (ripped the fuel hose in the process, hence my advice about emptying the tank) and all is good.
Good Luck - Patience and time is the key

Frustration the enemy! It's not too hard a job in the end.
