Tossing around the idea of a single carb setup on my 550

I know where most everyone will go and im not looking to outsmart the Suzuki engineers, i know im not going to beat the 4 carb setup for performance, it just comes down to simplicity of tuning and wanting to do something different for my around town bobber, not to mention the vm22ss i pulled off are toast. Im not located anywhere that i can just take my carbs to someone to be cleaned, repaired, setup and tuned, and my build budget is limited. i plan on fabbing my own manifold once i get my frame work done and know what kind of space im working with. my questions are what size carb should i go with and has anyone seen this done anywhere else. (links would be nice if available.)

Pictures or it ain't true!

Not sure if doable, or if it makes sense...If I understood you correctly, you have several reasons why you'd like to go down this route:

1. Carbs are beyond economical repair, i.e. super dead, deader than dead...etc
2. Don't wan't to hassle with four carbs instead of one (sync/tune)
3. You don't have money to pay somebody to fix'em up (or not willing to spend it)
4. You don't have anybody nearby to fix'em up
5. You can't/don't want do it by yourself
6. You want something special

..to which I have the following report/respond:

1. As said, show us some pictures...takes a lot for them to be beyond repair
2. I'm a newbie rider, and began working on my GS's only 1 to 1.5 years ago. It's easy with the right resources (see my signature)
3. See 2), not necessary to have somebody else to do it
4. Again, 2), and there's a lot of help and resources in here
5. See 4) and below this list
6. ...well yeah, can't have that with stock :)

The 550s are very cramped in the carburetor/airbox area. I'd say it'll be less of a hassle for you to bring the VM22 back to life, compared to all the work required to get a single carb setup.

Then again, maybe someone more knowledgeable might chime in. I'll take the VM22SS' off your hands then, btw
 
wow. interesting question. Haven't a clue really, but I won't let that stop me :)

I'd guess you'll need a carb with the right manifold volume/pressure to suck from enough from big jets ... to suit 275ccs (half of a 550-4) Maybe something off a yamaha XV750? or some other twin with a single carb. But splitting the intake into branches- not sure how that works! the manifolds w.ould necessarilly be two different lengths if you use separate tubes so starting will be tricky as will gas condensing on the longer tubes....Also, as mentioned space behind engine is a consideration
Building a manifold right across the back of the engine(like a car) would bebetter than 4 manifold tubes...wouldn't it?
Well good luck! You'll be a goto expert if you get this happening....

TWIN carbs-that's doable almost as simple and there are examples- I think there's even a setup for them for the 550 somewhere...
