What's the size of VM 26 carb drain plug?

I just noticed a fuel overflow on my 1980 KZ000 B4 LTD with VM26 carbswith accelerator pump I blame my needle seat and my floats.

Im on ebay and need to know the size and name of the fitting to adjust the floats using the clear tube method

Im at my wits end dealing with these carbs but I know this will end a lot of my headache.

In the picture below I need to know what the piece is called and the size of threads on the left. I am going to fit four of them to my carbs permanently.

I think they all have same thread on the angled drains,yours should be 28mm carbs if theyre origional anyway

If its just a stuck float bang on float bowl with a screwdriver handle few times

I did and it worked haha I just have no respoonse from the idle mixture screws and I know it needs to be done ha

Try a big can of this and a tank of gas run through them

I rigged a way to adjust my float bowls by shoving a small plastic tube in the drain plug.

All my problems almost disappeared after I adjusted my floats.

Turning the choke on doesn't red line my engine any more. My idle screws are active when I turn them in or out and the idle during cold and hot are controllable through the chokes cycle between temperatures without much fluctuation in RPMs. I still have to adjust more precisely but I found a have a worn needle (thing that lets fuel in and shuts it off inside the carb) The name escapes me right now. But I reset the float hight and BAM problem was still mostly solved.

Those floats are very important!

Anyways since you bring up Sea Foam, how does that do in the oil for cleaning the engine out?

Thats the needle/seat that controls gas flow when float raises/lowers,how far off were your floats?
I only use it in the fuel system,never tried it in the oil.

Where did you set the float levels to?

Don't waste your money on the that tool. Take a cheep bic pen and take it apart and gut it. Use the tapered end and install a clear tube over the slip end of the tapered end. Now screw the tapered portion into the float bowl drain and wa-la .99 tool. I am still using the one I made in 1979.

With the gasket on, I adjusted them to the lower end of of the bowls rim. Due to lack of tools, resources and money, I did all I could to get them as good as I could. On that note; my list of tools to buy multiplied haha. They aren't perfect but it runs much better. I need new boots now though. When I put the carbs back on last night I beat up and punctured a couple of the boots on the Airbox side.

Just make sure the carb rack/bike is level when setting them
