Remove the airbox and look into your carbs. You will see the flaps. actuate the choke and watch them.

Okay, I assume I can just adjust the chokecabel? No additional parts need change?

You should be able to adjust the cable housing at the clamp above the carbs. Pull the choke cable out so the choke is on (ensure the friction lock at the top is tight). Check your flaps. If they're not 100% closed, there should be a phillips screw clamping the choke cable housing to the bracket above the carbs. Loosen that screw and pull slightly on the housing to close the flaps the rest of the way, then hold it there and tighten the screw. Next time you actuate your choke, it should close them 100%.

Perfect battery mounted, with the same results as before.

It doens't even make a sound that it wants to go, I'm guessing the plugs.

Yesterday, I got it fired for like 5 seconds, and then it went dead.

Don't know if I was lucky or anything, but I got it started.

Took it for a 50 kilometer spin, only thing that I have to say, boy was great :)

Though I sometimes during accereleration from low rpm get a small "poof" from cylinder 4, it is no thread or is annoying or anything, it's just there :)

Got the plugs today.

And a 40 dollar plugtool-thing, cause I didn't have one in 18mm

And what do I see? I can't get that damn thing in the two center plugs :(

Just doesn't for me, can't get it all the way down to the plug.

I still have the problems by the way, I'll check the choke the next time.

When I tore down my carbs, I discovered that the choke butterflys werent closing or opening completely.  I loosened all the screws holding on the butterfly's themselves and then retightened them.  They now open and close completely and easily.  I guess whoever rebuilt the carbs in the past tightened them so they were rubbing on the insides of the carbs and causing some friction.

About the plug puller, I found that when I had bought a regular long socket, I couldnt get at the two center plugs, I ended up having to grind around the wrench end of the socket to make it tapered and then it would fit down in there on an extension.

I got a plug socket from sears and it fit my 750 fine. I suppose the other bikes may be a bit smaller in clearance.

I don't feel like grinding down my 40 dollar tool :)

Could I have clogged carburettors?

Same here.  The spark plug tool I use for the 750 wouldn't work for the 550, so I bought a cheap, thin-walled, deep, 18mm socket that fits perfectly.  I even use it for the 750 now because it's easier than what I had before.

No no no no, dont grind on a $40 tool, grind on a $3 dollar tool (Napa) and make it as useful as a $40 tool.

Ditto- got a thinwalled impact socket from Harbor Freight for $2, and ground down the drive shoulder almost to the drive opening itself. Works great on the outside plugs of my 550, it's still a little snug on the inside plugs, but it works.

Have you checked your bike's tool kit for a spark plug tool?  Or, did the PO keep it for himself?  Honda provided one with the bike originally.

Yeah, and those buggers are as rare as hens' teeth. My local shop has one, they welded a 3/8" drive socket into the round end so you could use it with a socket wrench. It's a wonderful thing, but those stamped socket drivers are, as I said, incredibly hard to find.
I picked one up at a garage sale, but it was for lawn mowers. Turns out both sides (it was double-ended) were the wrong size- too big, or too small. Oh well, only 0.25 wasted.

Seeing as you've already dropped the cash on the tool the best thing I could advise is give the tool a name.  Only expensive tools get names.   :P
