So guys this is my first post. I personally always wanted to own a Goldwing and I so happened to inherited a 1988 Goldwing that has been sitting for about 6 years. Overall is in great condition but because it was sitting, there are some inherent issues. I have already cleaned out the gas tank, replaced the fuel pump being the reason he originally parked it, I have also replaced the battery, fuel filter and plugs . My issue is, after installing the new fuel pump today, I turned up the choke and it started for about 5 second then it stopped and will not start again, just turns over. I noticed a tube that sits behind the petcock was pouring out fuel every time I attempt to start it. The tube goes down both sides of the air filter down to I believe the carb. I did open the petcock after this issue and seemed pretty clean but will be rebuilding looks kind of brittle so it will be rebuilt the next couple days. today. Not sure if that has anything to do with the issue. Is there supposed to be fuel coming out that tube? This tube sees to only be present in the 88 Model. If not, why is it leaking and would it have something to do with it not cranking?

Not sure where my original post went so I'm posting again.

I recently inherited a 1988 Goldwing that has been sitting for about 6 years. The original owner parked it when his home was used to film the movie Blended and never really got on it since.

Overall is in great condition but because it was sitting, there are some inherent issues.

I have already cleaned out the gas tank, the fuel pump was bad, being the reason he originally parked it, I have replaced the battery and plugs as well.

My issue was, after installing the new fuel pump today, I turned up the choke and it tried to start for a few seconds then it stopped and will not start again, just turns over. I noticed a tube that sits behind the petcock was pouring out fuel every time I attempt to start it. This tube goes down on both sides of the air filter down to I believe the carb.

I did open the petcock after this issue and seemed pretty clean but will be rebuilding it today had a few cracks in the rubber.

Is there supposed to be fuel coming out of that tube and what is it for? It looks to be only on the 88 models. The California version has a hose that goes to a canister connected to it but the other versions, it's just an open tube. Would a bad petcock make fuel poor out like tube? Could the carbs be bad causing this? HELP 馃槱

Question two
The new fuel pump had an extra hose that attaches to the inside of the tank that my old one did not have. Was that OK to connect and could that have anything to do with the issue?

After trying to start the bike, the tank held pressure. Heard the rush of air once I opened the gas cap.

don't know why, but your post got hung up in the forum server's spam catcher.

noted your info in the post, and stamped you as 'Approved' and there you are.

That is a vent pipe and fuel should not be coming out of it. What it indicates is the carbs are flooding over seriously and will need to be removed and rebuilt.

That's what I thought, half this bike will be rebuilt when I get done with this 馃榿 thank you for your input. I will report back once I get it rebuilt

I have pulled the carbs and petcock and will be rebuilding both. Question, Any idea where to purchase the S shaped fuel hose that goes into the CARB? Its very hard and may break taking it off.

While the one for an 88 is unlisted, 89 and on are still good from Honda or Partszilla. In the parts diagrams they look to be the same basic shape. Although the photo looks more like a "C" than an "S".

If you had used Electrolysis on that assembly, all of the rust would have disappeared.

Carbs rebuild, they where completely siezed so it definitely needed a good rebuild. I got everything reinstalled and did a bench sync and seems to run fair. So here are the new hopefully minor issues since starting it for the first time.
There is a little popping noises coming from the exhaust, maybe it's just cleaning itself out from sitting so long and or burning the fuel that's sitting in the exhaust from the original issue. I also added seafoam to the fure at a higher than needed ratio, maybe that's it. I haven't driven it yet so hopefully it will clear itself up. Also, the air cleaner in off the bike at the moment, maybe that's it.
Second question, The pilot screws were removed and replaced. I dont know what the original settings were but I turned them both out 2.25 turns. Does that sound right?
Third question, I did a bench sync, and it's running at about 800 to 900 rpm. If my bench sync is off, how do I tell?
Last question, it seems like there is more air suction coming into the lest side of the carb than the right. Is that normal?

You really need to have the air filter in place before adjusting the carbs. It will run a little lean without the air filter. Obviously that pilot screw setting was good enough to get it going, but you should adjust them individually now that it is running.

That indicates they need to be synched. A bench synch is good enough to get it going to do a proper synch.
