Hi. Does anyone have a manual for the mikuni carbs on an sb6r? Or even better a step by step procedure for removal, cleaning and set up and replacement of them.
got them done just over 4 months ago but misfire is back. Steady on number 2 cylinder. Changed plugs and its got 99ron in the tank. Inside tank looks fine.
Is it always this big a pain in the ar@e?
This will be my first time doing carbs so dont wont to end up in a worse situation than when I started lol.

Buy a Suzuki GSX-R1100W manual 93 - 98
When you had your carbs stripped did they replace the seals ??? The ethanol in petrol causes the seals to harden and shrink. The seal on the floats that goes over the fuel vales seems to be a favourite so the carb can flood.
Replace them with Viton seals, you can get a kit from http://litetek.co/Carb_Kit_Suzuki_GSXR1100.html.

Stripping a carb is fairly straightforward but before you do remember only work on one carb at a time. Use a big sheet of white paper so if you drop a small part you can find it more easily. Use a 1/4 drive socket and bits, make sure the screw driver bit fits properly push down as you unscrew so you don't round out the screw head.

Why not have a look for a Motorcycle Maintenance course at a college ? They do them in the evening and if you're at this level you should be able to handle the top level. They don't rebuild an engine but they check valve tollerances. It's good ptactical knowledge, especially if you own a Bimota. You can claim a halfords trade card and get some student discounts too

I have ordered kit A. Should be here in a week. As well as lack of motorcycle knowledge my biggest problem is geography. I live in the orkney islands. College courses up here consist of archeology and tourism. I am a quick learner and keen so I will have a go. Whats the worst that can happen lol.

As you strip the, remember to take note of and weight down all of the current settings like...

Pilot screws - number of turns out from bottom ie. 2 3/4 turns or what ever it is.
All jet sizes - some cylinders may have different size carbs to others.
Float heights.

Make sure to clean out all of the passageways and components carefully.
Check the diaphragms for tears.
Check the Needles and emulsion tubes for wear - out of round.

Also, the carbs will definitely need to be balanced (synchronised) when you put it back together. Don't skip this step, it is most important to get it running properly.

I have spent MANY hours and MANY $$$$ on this problem.....Ethanol's only purpose is to ruin perfectly good carbs.... Rolling Eyes

The Suzuki manual has the synchronization sequence for you. Just get one of the vacuum gauges online and go for it. It is easier than it sounds and easier than it looks....Good Luck!

Try these, they helped me. (these will give you good general knowledge that you can apply to your issues)

http://kawtriple.com/mraxl/carb/carbadj.htm

http://forums.pstuning.com/index.php?showtopic=545

and finally, if all else fails, this:
...Be sure to double check your spacing. I think these may be off, can't remember (too old), but you can use your OEM spacer bars and make these work. However, if you lack mechanical ability, this might be best left to the professionals. I am trying to get this purchase past the funds distribution controller...(the wife)...Hopefully in the spring...I will most likely have to do that "special" thing, to expedite the approval process.

You can use one of these ... A carb Synchrometer. They're a lot easier to use than vacuum gauges

Thank you all so much for the great advice. Its truely a world wide problem isnt it. One person in Australia, one in Utah and a couple of Brits.
I was going to do one carb at a time. A friend who lives locally has a ultrasonic bath. When I have the unit stripped I assumed that the bath would ensure it was as clean as possible.
I have ordered the webber vacume gauge that you listed. That will come in handy as I also inherited a stage 4 tuned classic mini cooper s. Its fitted with a webber 45. Not many miles on that vehicle, only 13.
I go back to work on Wednesday night so will be new year until I make a start. Dont want to start until I know I can get finished.
Again, thanks for all the great advice.
