Choke problem?

Postby tyrevere » Sun Aug 23, 2015 11:07 pm



Hi guys / gals I was hoping someone could steer me in the right direction before I tear apart my bike trying to figure out this problem.

I have a 1988 1500 goldwing, it has 59,000 miles on it. The problem I am having is it feels like it is starving for gas when I'm driving it. It idles fine but when I'm driving it feels like it's running on 5 1/2 cylinders. I have changed the spark plugs and hasn't changed a thing. The carbs have been serviced about 2 years ago and I ride it as much as I can all year. The one thing I have noticed is that if I leave the choke on about 1/4 it runs like its brand new. I close the choke and then it acts up. So is it starving for air? Do I get or adjust the carb cable? Any help would be great!!

On a side note, anyone else have a problem that when it rains while the bike is off that you get a vapor lock in cylinder #4? This has been happening since day 1 that I got the bike about 5 years ago. If I keep it covered it starts right up. If not covered during rain I need to remove the spark plug and turn the engine over once and then it runs fine. The dealer has no idea why or how it's happening. There is no oil , fuel , or coolant loss what so ever.

Thanks guys in advance for any help

G'day!

cant help about the choke (I had my own choke problems but the other way)

But I would check your plug cap, drain hole in the head to let rain/wash water through to the ground.

My 88 was running smooth but gutless, when I tore her down 3&4 plugs were brand new, I had a naughty coil or plug lead, so I replaced them all with a nice second hand set

Now after much gnashing of teeth she purrs along nicely.

Best of luck, Peter.

Agreed - if you are having a rain-related electrical problem on just one cylinder, check the plug drain hole on that cylinder - shove a wire down through it to make sure it is clear.

How long since you changed the fuel filter?

I guess another question is ...Has it always been this way or just progressively gotten worse.

At some point,lift the cover to the air cleaner and start the bike.Rap the throttle and watch each slide.Verify they both move.

And I can see fuel going into both sides
