ok,so,if i understand right,the petcock is some what working,but when the bike is off,the petcock should hold the gas back.
but you say the rear carb is constantly taking in gas,could this be the result from just the petcock not holding back the gas,and thats why the rear carb is taking in the gas.

i havnt got it confirmed just yet,but a goldwing diaphragm might work,just gotta use the old parts from your petcock.
but im not sure,i dont have a old superhawk diaphragm to match up to the goldwing diaphragm.
since you have the old one,you might be able to try and match it to the goldwing or another kit.

as stated above,this part number should be the petcock rebuild kit 16953-ML0-034
if you type it into google,you get a mass amount of sites,find the cheapest and call the company and talk to the person,so you can make sure its not on back order and they have it in stock.
otherwise,its gonna be a long wait.

sorry for so many posts,but so we and alot of people reading this are on the same page,read and look at this link.
to anybody needing a petcock rebuild,just call your desired company and make sure they have it in stock,and you good to go.
its possible they dont exist,so be ready for that,but it is a starting point.
and from what i just been researching,the goldwing kit,or just the diaphragm just might work.
ok,i will shut up now

i believe it should,but one part of bike i havnt really dived into is the carbs dis-assembly,so i cant answer 100% on that.
i would think the petcock helps in that process.hopefully,someone can chime in on that and give you a definite answer.

Yes it should but the key would is "if"......
The down side is if a float valve sticks or maybe gets a little dirt on it, you then get a crankcase full of fuel.
So, yeah, it can work but is it worth taking that kind of chance?

Correct. The floats will stop fuel from flowing if they are functioning correctly. The vacuum petcock is a safety device to stop the fuel flow in case of a float failure. The petcock was working AT LEAST 90 percent before you removed the diaphragm, but since you bypassed the safety device, now the end result it painfully obvious. The rear float is not functioning.
When you asked earlier about how to remove the float needle seat, I presumed that you had already taken the carbs off and removed the float and needle.

I understand about the petcock. And I did have the floats and valve off but they looked good float was normal color and there was no gas in them valve didn't have an imprint so figures they were good cur gas is coming out of the Carb into intake so they are my only guess at the problem I will order petcock diaphragm on Tue since everyone is closed but thanks for the help everyone without you guys. Would have taken me a lot longer keep you posted any thoughts please if you think I'm wrong but tinkering I'm on the right track and the more digging I do the more I can't wait to ride this amazing machine these bikes are pretty bad

Yes this would mean it is not working for some reason. Until you figure out why it will keep happening whenever the bike is running, working petcock or not.

The only other possibility I can see would be if the carb body has a crack somewhere along one of the fuel supply bores within the float chamber (EXTREMELY unlikely).
If cracked, the fracture would have to be pretty severe in order to flow that much fuel, IMO.
Is the float pin bent or damaged in any way? Is the pin missing?? Does the float move freely? Did you shine a light into the float seat and check for irregularities? How did you clean the seat?
If all else is good, then most likely the needle is bad. It only takes a very small score mark to cause problems.
I had a float problem on a GS1000. The #2 carb would overflow continually when refilling the float bowls after the bike had been sitting for at least a week. Over time the fuel in those old VM carbs would evaporate and leave the bowls dry. Using the plastic handle of a screwdriver and tapping on the outside of the float bowl would make the flow stop. The carbs would then work properly until the float bowls were drained, or until it sat unused for about a week. Later I discovered that the needle in that carb was bad.

and very important,you might want to invest in another oil filter and more oil.the first run thru is gonna be dirty and gas residue,when you do get the parts you need.
can do cheap filter and rotella oil,just not sure which rotella to use.

Well it's impossible for a lifter to hit your piston because the head is in the way. ;-) It's really hard to diognose these problems over the net without being able to be there and see what's going on. But yeah make sure that petcock is proper before you start trying to run it much more.

Well to stop the petcock I cut both seal parts of the diaphragm so I could seal the petcock so if I have the gas on its free flowing pluged off the vacuum part of the petcock. Then I put a clip on the float valve so that it would go in the valve seat a lil more I did scar the seat a lil when I tried to remove it before I new you couldn't. But I cleaned that up so it could be I fixed the seat or the clip worked but that it

Eh, it'll affect the way the bike runs, but it can run disconnected if you want... it's not catastrophic or damaging in any way. Don't forget about it, but my very important list includes things like CCT's/timing, brakes, fuel spilling all over the exhaust, etc...

Start shopping for a set of used carbs. Check the classifieds forum on this website. If nobody is selling any, start a 'Wanted' thread in that forum.
