Update -
I got the new float needles today and installed them. It didn't solve my issue. I have swapped needles and seats from Carbs 1 and 2 to Carbs 3 and 4, it still overflowed on Carbs 1 and 2. I then swapped floats from Carbs 1 and 2 to Carbs 3 and 4. Now I have Carbs 2 and 4 overflowing. When filling the Carbs from dry state, gas pours out of Carbs 1 and 2 every time then it stops suddenly. I am stumped Guys. I have posted a video below:
I just noticed something while putting the floats in a bowl of water to float, there are numbers stamped on them but they are all different. The numbers are not uniformed across all of the floats. Could it be that while the Carbs are the original some of the floats or all of the floats are not for these specific Carbs?Last edited by GalDemSuga; 08-14-2020, 09:17 PM.My Girls:

Having not read back thru all the posts
1. Have you tested the floats to ensure they float?
2. Are you measuring the float height correctly?
Hold the carb rack engine side down and rotate until the float tab just touches the post on the needle. Measure to the step on the float
3. Did you install the new O rings?1978 GS 1000 (since new)

Today I investigated the Carbs and I found that 3 of the 4 needle seats are different and this is why they won't seal. One is different because its damaged internally. Its been punched in somehow making the hole smaller. I just looked at them and all of them are Mikuni 2.0 seats.
See videos below:

Carbs are back together and so far no leaks. I used rubber tipped float valves and replaced the valve seats with some used and shorter valves that the Seller of the needle valves gave to me. Luckily he is a local Guy and helped me out.

Marioly out of subject but cannot get the hang of creating a new post. I have a GS1100GK and some of the plastic in the fairings and side boxes need fixing. Can anyone tell me what material they are made of and if they are repairable please?

Folks
I'm back to the original issue of carbs leaking into the airbox and intake boots.
1. I've pulled them off and removed the needle valve and seats. I've cut the seats down so the the floats will only contact the needles. Installed new O-rings and checked float heights (22.4mm) and still have the issue.
2. I'm using my vacuum petcock on my tank so whatever gas is in the line(bike not running) is making its way into the airbox and intake boots, whereas if I'm using the auxiliary tank it just flows continuously into the airbox and intake boots.
3. I don't think gas is getting by the floats but rather somewhere else in the carb assemblies BUT where? Could it be the choke passages that is causing the flooding?My Girls:

Okay, please forgive, but I did NOT watch all your videos. A couple of things I noticed immediately, though, was that you plugged the breather lines from the float bowls. Why? These need to vent to normalize the pressure over the fuel in the float bowl. Another thing, your external fuel bottle is hanging on the ceiling, which creates a LOT of head pressure on the float valves. Your remote tank must be roughly at normal tank level, otherwise you will overpower the float valves and cause overflow.
Edit: I just went back and read more of this thread, and it seems you realize that tank can't be on the ceiling. Hope so anyway.
Regarding the float valves, cutting down the valves, replacing the needles with something other than the originals, etc, is a HARD STOP.
Do yourself a favor and buy four brand new Mikuni or keyster brand float valves and install them. NOT needles, complete valves. Then set up a remote carb holding stand, and perform the clear tube test to assure the fuel level is consistent, and steady, in each carb. No offense, but this thread is two years old and you still don't have a solution. No shortcuts.
