Carbs leak through over flow

[SOCKinside]

When parked after riding, carbs tend to leak through over flow, I'm guessing it's a floater issue? It's not a big leak but nonetheless a leak

Which bike do you have? is the petcock manual or vacuum? Have the carbs been worked on? We need more info.

What year?
78-79 had different carbs and petcock from the '80.
Did you leave your bike parked with the petcock on prime?
Sidestand or Centerstand?

i dont know if my petcock is on prime or on, its missing the lever it only has a side stand! 1979 GS1000E

i found this one on ebay, but mine looks just like it, now that u mention it, it might just be on prime, im gonna try to turn it with a small end flat head

[SOCKinside]

any one have any ideas?

[SOCKinside]

this is how its sitting now?

I believe the longer end is the "pointer" and therefore that would be prime..try turning it 180 so its pointing to the front of the bike..If it goes then that would most likely be reserve..thus straight up and down would be ON. As for whats leaking..could also be the bowl gaskets and gas will run to the lowest point before dripping. Get a good trouble light and wipe each carb down and look at the gaskets to see any new weeping. Also look closely at the fuel tee and the transfer tubes. If you have hoses on them and the outside of them are dry but it drips out the hose, then that would tell me its a float height being just a tad too low..raise it up 1MM and then see what happens. While your in there, take a Qtip and some laquer thinner and swab out the float needle seat too..a little build up on them will cause leakage as well.

horizontal is run, vertical is prime.

Thanks guys for your time and knowledge, I'm gonna get to it now!

My question would be: why does your '79 bike have the "dreaded '80 petcock"?

.

[SOCKinside]

i had no idea it was an 80 petcock, thanks steve, is this the stock tank???

[Nessism]

That petcock came on the 1980 bikes, but at least one person here said their '79 GS1000 came with one also. Maybe Suzuki made a late production change over? What is the manufacturing month of this bike?

Carbs leak through over flow

I have a 1979 GS-850G that I just finished with a complete top end, carb rebuild, and Dyna Electronic Ignition job. Runs great, BUT it appears I need to rebuild the petcock as well. It spits gas back out through the over flow tubes two or three times after shut off. Does that sound like a petcock problem? What is the Dreaded 80's Petcock problem? Is that what I might have? What the recommended solution?

ALSO, I replaced my starter while I had the carbs off and now - even before - it just clicks sometimes and other times it kicks right in when I hit the button. Could this be my button is in need of repair, cleaning, or replacement? Other possibilities?
