Hi. I try today do vacuum sync. I just make it worst. I don't know where to start . How to pull off vacuum in nr.3 ? Which carb I should adjust first? When is vacuum in one carb higher then I have to close butterfly? On GS650GL is the middle one screw under choke and throttle holder . It's difficult to access is there any special tool for adjusting?

20150919_102704.jpgYes I plug vacuum line from carb#2 and I use basscliff's site like bible. Also I know that carb #3 is master. Actually I think that carb #3 is on my bike is open by idle mixture knob while carb #1 #2 #4 is not open enough. what you think about this theory.

PS: how to screw that 8mm nut between carb #2 and #3 ?? Basskliff is using tool which I can't unleess I take off choke holder

It is not that difficult to remove the "choke" holder, but there is a way to use a nut driver or socket on there that will not require it. :-k

With the engine NOT RUNNING, turn the throttle about half way, use a long extension on your socket wrench or nut driver, reach down from where the back of the fuel tank would be to loosen the locknut.

The tricky part is after you get the vacuum levels set and you need to tighten that nut. Use your fingers to snug it down as much as you can, verify your vacuum levels, turn the engine off. Rotate the throttle again, tighten the nut with your wrench. Start the engine again to see if the vacuum levels have changed. You may go through these steps a few times or you might get lucky and have it good the first time.

after 40 min I get this results20150919_200010[1].jpg But is magic to set it right. Good luck with syncing to everybody
 
Basically I first do a good bench sync. I then sync the #2 carb to #3. I then sync the #4 to #3 and then the #1 to #2. Some times you have to go a little back and forth to get them all synced.
 
20150920_152401.jpg This is the best thing which I did to my bike------ since I am owner :-)))
1500rpm
 
I notice a fan in your last pic, good way to go, I use the same because it usualy take me a while to get the results I'm happy with.

I see you are from UK. Do you know where to buy sealing for front fork and brake hose front and rear gs650gl 1982
 
Try Wemoto there in the UK, but eBay should be quite helpful, do you have any Suzuki main dealers in your neck of the woods.
