74 CB550 Carb Rebuild, 1st time. Where to Start?

So, Ive pretty much done overhauling this bike and I have ordered 4 carb kits from DCC. I have never touched bike carbs and I havent the first clue where to begin besides the research stage. I have also realized that I need to work with my setup. I have 4 pods which I have be told that Carbs "can NEVER be Properly Tuned with pods" and I have a 4into1 exhaust that I am adding the 12" shorty DCC muffler to.

Before I rip everything apart I wanted to ask where are the resources, is there a cb550 carb 101 guide? youtube videos, tips, tricks etc. I have no problem tackling any job this bike can give me as learning throughout the way is what I enjoy most.

Where should I start? I have the carb kits, im assuming I should get an assortment of Jets, how specific are they should local bike shops have them or is that a Honda OEM part I can get in.

Thanks
 
Get online and see if you can track down a manual for your bike that has those carbs, comes in handy when you forget what goes where. The idea is to be methodical and organized. When I rebuild carbs I take them off the bike as a whole unit then I work on one at a time. It also helps if you get an old cookie sheet and do all your work on that. it catches all the parts and fuel that might leak out. If they aren't dirty or gummed up with old gas don't mess with them. Just change the parts that come with the kit, you don't need to tear down the whole carb. Lighly blow compressed air through all the circuit passages and make sure they are clear. Pipe cleaners and a can of carb cleaners are good to for gummed up parts. Since you have pods and different exhaust you'll need larger jets. Ask a few people that have your same bike and same setup and see what they are running as a reference to what you will need. It won't be exactly the same but a good place to start and save you some time. Jetting is a pain in the ass and takes a while to get it right.

is there anything wrong with your carbs now?

Well I dont think so, But I haven't really had it running much. it is a project bike and I have had it running and Im assuming that with the changes I have made It will need to be re jetted. I have also been tearing everything down and fixing it and I would like to have the peace of mind that my carbs are all A-oK.

Awesome, thanks That is all great and useful info.

What about Bench synching? ive been reading alot on that lately and its a term I had never heard until starting this project.

Cheers
 
Syncing the carbs makes sures that all 4 carbs are pulling the same amount of vacuum while running. To bench sync all you do is after the carbs are assembled is make sure all the slides are at the same position (one isn't anymore open than the other 3.) again this is a starting point, the only way to really sync the carbs is measure the vacuum they pull while the motor is running

Awesome thats pretty much what I had come up with but I have never had a chance to do it myself yet
 
Buy the Honda factory service manual for your bike and then consider a Haynes manual.
