I also ordered new plugs, D8E I was told by a mechanic that those plugs burn better and should help some.

Your mechanic is wrong.  The 550 takes D7EA plugs, unless you are racing full bore through the hot desert.  If you stick with D8E you will have to wait for the bike to completely warm up before you can ride it.  D8 is a colder spark plug.

The 8 plugs and 7 plugs are close on the scale, since I already ordered them I will at least try them out.. At least while my new D7e plugs ship to me.

I just rebuilt the carbs so all the parts that came in the kit are new and on the carbs so I will just use those.
We just had a thread where the owner's run issues were fixed by replacing the after-market carb kit's brass components with actual Honda parts.
Aftermarket kits are cheaper than Honda parts, but where do they save the money?  Could it be on ill toleranced parts or the extra people to check the parts making sure they comply with spec?

Yea, the kit I used was direct from Honda from the parts counter at Ace Honda in Kenosha.. so they should be good.  At least I hope so.

I still need to make sure that the timing is correct and as far as I can tell the wet on the plug in the picture was just gas as an hour later it was not wet any longer. At least I hope so because if I have to take the heads off I am going to pull my hair out.
You can still ride with no hair.  

Pretty sure my wife would leave me if I was bald! ;-)

I tried to install the air box but did not have any instuctions. At least on this post I have a better idea, however if anyone finds a link that shows/describes how to install them I would love it if you could post that link. I called a friend of a friend that works at Honda as a mechanic in Ill and he said depending on the carbs on the CB550 I may have no choice but to use the air box since there were some 550's made with carbs that will only work with the factory air box.
Probably thinking of the 77-78 CB550K model lean burn set ups.  Gotta re-jet those PD carbs if you change the air filter set up or the exhaust.  Earlier carbs are more forgiving as they run a bit richer on the pilot circuit.
I most certainly favor the stock air box, despite the minor struggle to install the carbs it adds.
Here are the parts you need to restore the bike to stock:

All except parts 13, 30, 32, and the filter box cover get placed in the frame before the carbs are installed.

Cheers,

Sweet thanks for the link and info!!!

Ok, boy am I glad I ordered those new coils. I was just out testing and the coil for the two middle cylinders is not working no spark to the middle two plugs at all. After messing and testing it seems it has gone bad and is probably the root of all my troubles at least I hope so. I ordered the parts last Monday so hoping they get here soon! I will update once I have the new coils in since I do not have any backups.

Fingers crossed!

Ok here it is in action, just wish I had a better camera... oh well. Also keep in mind its not really timed, I just kinda eye balled it and the carbs are not sync'd I just got my gauges so maybe next weekend I can knock both those items out.
