You should of taken the tubes out before you put them in the tank. Why would you want to take the bank apart??
I would not advise someone to take these apart unless they know what they are getting into. There are so, so many little parts to them. But, you can get them apart to change the 0'rings in the T pipes by taking the 8 big cross head screws out of the big alloy rail that holds them together.
Should be in the kit but, i have never got one from DSS. I always get from Japan or the Dutch carb guru.Yes, if you remove those 8 screws the cast plate (as you have called it) will swing up and all the carb body's will be lose enough to change the O'rings on the T pipe's. It also maybe worth paying someone to sonic clean the bank in one piece.
I think you are on about the vent tubes. You just cut a bit of hose for those.
Well worth the money. Need to be stripped down a bit more before sonic clean them. Yep, those are the tubes.
Sorry but, i can not see what stage you are at. From your last picture you need to take out those air screws. Did you get the tubes out? If you need a new screw kit try TSS Fasteners. Tina is a diamond. She may not list a kit for your carbs but, she has one because i work with this company to provide them with fasteners sizes for all CB & CD motorcycles.
