I disassembled the carbs and ran them through my ebay ultrasonic cleaner with w touch of Dawn dish soap. Came out nice and clean and now time for the assembly.
Ordered a quality rebuild kit from ebay as per the suggestions on this forum. Now for the questions.
I have a few "left over" parts after my rebuild as seen in the first picture. Any suggestions?
Also my carbs are missing one of the plugs as seen in the last picture. Are they generic to Mikuni? I assume they MUST be installed? Suggestions as to where I might purchase them?
My carbs have slightly different brackets under the float bowls that another set of Mikuni (picked up some cheap spares to learn on) does not?
Thanks

Those aluminum disc things are intended to seal over the pilot screw passage. Throw them in the trash. They are not needed.

As for the pilot jet plug that you're missing, try this:

You'll need an o-ring for it as well.

Installing the aluminum disc over the pilot screws isn't the worst thing in the world, but if protection from the elements is a concern, I'd rather fill the cavity above the screw with something like waterproof grease.

Mikuni that was installed on Yamahas came with rubber plugs for pilot screws. Part number is 22F-14991-00-00. Still could be sourced.

What about those springs that seem to be left over? Any thoughts?

I have a few questions for BS32 as well... I got them in parts.
1) jet needle setting (4d31) how many "clips" from top? I attached a picture.
2) where to measure float height from the float? i am following this tutorial since it is my only lead (cant find a manual - 1982 z650f3) thexscafedotcom.files.wordpress.com/2014...rebuild_tutorial.pdf
I need someone to confirm the measurement is correct. For now, the height (22,4give or take 1mm) is set on top of the float (in the attached picture B option).

Hi to all. I think this is my first post/comment on this forum.
I have a few questions for BS32 as well... I got them in parts.
1) jet needle setting (4d31) how many "clips" from top? I attached a picture.
2) where to measure float height from the float? i am following this tutorial since it is my only lead (cant find a manual - 1982 z650f3) thexscafedotcom.files.wordpress.com/2014...rebuild_tutorial.pdf

Are those the stock needles, or some aftermarket needles from some "carb kits?" Stock Mikuni is generally preferable. If forced to use the aftermarket needles, put the clip is the middle position and adjust for best running. And realize, the carbs are set up for using the airbox, not pods.
The tutorial highlights the correct measurement location. Float height isn't critical though, fuel level is. Measure the fuel level to 4mm below the edge of the float bowl.

now the problem is spark plugs are lean to my knowledge. Cold start is difficult, because it runs on middle 2 cylinders, but it gets better if i put my hand over airbox intake (lean again?)
in need of a third opinion here.
