Hey all!

It's been a long while since I last posted on here. I suppose that's what I get for only posting after experiencing a problem. :grin3:

Okay so on Thanksgiving day, I took about a 300 mile trip to see my in-laws for dinner. On the way home that night (and brrrrrr was it cold!), I stopped off to top-off the fuel tank. Shortly after getting back on the road, my Goldwing started slowing down and I lost power. She dropped from 70mph to about 35mph and acted as though she wanted to die. The more throttle you give, the more she started sputtering and jerking. So I maintained just enough throttle to keep her going. About 5 miles later, she picked up power and returned to normal.

Hmmmm? Could be a gas filter. Might also be one of the floats stuck open and flooding out the engine. Might have also been very bad gas since I bought it from a gas station (Murphy Gas Station) that I ordinarily do not use. But then I thought about the gas cap.

Once she picked up speed again, all was back to normal no matter how much load I put on her. Right now she's doing just fine. Starts right up, no loss of power, and hits well on all gears and at any throttle load.

I'm thinking possibly bad fuel from a cheap gas station (water maybe). Or the gas cap was temporarily stuck closed and not allowing air to enter the tank.

So next week I am replacing the fuel filter, as well as the gas cap. I've already cleaned the gas cap once before, so this time I think I will just replace it.

Anyone ever experience this problem before?

I had something similar happen on my 88. The first time, it would idle fine, but as soon as you started giving it gas, it would loose power. You could slowly get it up to speed, but not have any pulling power. It ended up being a broken vacuum hose that is behind the left intake manifold. Replaced it, good as new.

The second time was the gas cap. Replaced it, bike ran great again.

Perhaps water, but I would also look at the vacuum lines and the vacuum fuel shutoff valve.

the Walmart Murphy gas stations pump a lot of fuel, I doubt that it had any water in it.
just to be on the safe side though, dump in a half can of Sea Foam, that is what it is made for in the first place.

All good theories but I will add two more. Might be a failing fuel pump or sticking slide in the carb. :)

I've had this very thing happen on my last 2 trips. Each of these was 2500 miles. Both times I'd just filled up. Both times it was at reservation stations. A few miles from fillup the bike died or spluttered to a stop. In each case I managed to get it going again and had no problem after that. First time I figured water in the fuel. But twice? My filter is newish OEM. My fuel pump has about 40k miles on it. Scary. I don't know what caused it. It's a '99 and a real mofo to try fixing or debugging on the side of the road a thousand miles from home.
I had a similar problem once which turned out to be a disintegrated fuel filter (Emgo). Another time it was the fuel pump but it reacted badly when the tank wasn't full. I've no idea what the latest 2 events were caused by. If you figure yours out, please post it. I will too.

Was just reading Terry's post and a thought came to mind. I have no idea if it is a valid solution in either case but just some old fashion comm9n sense. If you assume there is some debris in the gas tank it would lay pretty much harmless at the bottom. When you fill the tank the fuel rushing in could churn up the debris and put it temporarily in suspension. The sreen on the end of the pick up tube or filter could filter it out and restrict or stop the flow of fuel. The pressure would hold the bebris in place. When the bike dies or a long decel or idle would allow the debris an opportunity to drop off anf fall harmlessley back to the bottom of the tank. I would think it would be more likely when you are filling a really low tank, but maybe not?? Just something else to consider. :)

that debris idea and it settling back out, is sound.
on long trips, I would make a spare fuel filter a must to carry with you.

Hmmmmm!

Actually, after the first incident last year I put in a new filter and checked the old. There was nothing in it. Good idea though.

+1... If it happens again, then by-pass the Fuel Shutoff Valve... Those things seem to always go bad

You mean the petcock? I would expect that to just plumb fail. Or could it screw up sporadically?

...yes "Petcock". They can "partially" fail, or "totally" fail.


The internal rubber diaphragm goes bad, and/or the vacuum source (to operate it) is bad/weak/intermittent.


They just suck, really... cause more harm than good

personally, that should have been an electric fuel shutoff valve from the factory.


because it will not open until the engine creates vacuum.
that wastes the first two revolutions of the engine.

Well I did pick up a repair kit some time ago. Maybe I should just put it on.

Reporting back - I saw a list of symptoms for bad petcock on GoldwingDocs, one of which matched mine i.e. engine dies and then restarts and continues running. So I rebuilt the petcock with a Showchrome kit and have had no problems since. I just concluded a 2500 miler without a hiccup. The old diaphragm was not torn but was a bit limp which, it seems, would account for the symptoms.

I saw that exact problem once in a car. Would lose power, then die, but when restarted would usually be fine for a while. After checking the usual suspects and noticing it had a brand new fuel cap, I dropped the tank and found a blue service station paper towel in the tank. No doubt someone's idea of a make shift gas cap at one time.
