Gas dripping out of tube under bike

Hi Folks;

I bought my friend's 1996 GL1500 with appx 36,000 miles on it. I also have a 1990 GL1500 with 78,000 miles. When I drive the '96, there is gas dripping out of one of the tubes that sticks out of the bottom near the engine. My '90 has never done this.

What is this telling me? My buddy said the local HD dealer had cleaned and adjusted the carb but I am wondering if the shop did something wrong. The cycle hasn't been run much in the past 3 years due to his health. Do I need to run some carb cleaner through it or are some more drastic measures in order? I just got the bike and haven't had a chance to inventory the maintenance that needs to be done to it.


I also noted the exhaust is louder on the 96 compared to the 90? Should they sound the same or ass the '96 designed to be 'throatier"? I'll get some pictures and post them in the next few days.

You need to take it to a motorcycle mechanic. (Not an HD guy)

My guess is you have a float that doesn't anymore or is badly out of adjustment. Those are overflow tubes under the bike.

Why ain't we ridin'?

My thought exactly. You have a carb(s) overflowing which will have to be dealt with by someone who knows what they are doing. And someone, maybe the same hardly guy, probably modified the exhaust.

With no God over the state, the state then becomes not the defender of liberty but the definer of liberty.

If I disagree with you it's simply because you're wrong.

It's possible that the float stuck to the bottom if it sat with gas in it and the gas evaporated. (This can happen in a few days in Texas)

I started leaving the petcock open on my 1200 to keep gas in the bowl so the float would not stick.

If float is stuck it should unstick after soaking in new gas for a day or two. If it doesn't unstick, you are in for a carb disassembly and cleaning (or worse as Bike and Dennis mentioned).

It is a good thing it is flowing out of the overflow tube. If that gets plugged up the gas winds up in the cylinder for hydrolock or dilutes the oil in the bottom end.

Would be helpful to always park it on the Center Stand....

Probably a stuck float but check the easy things first - make sure the carburetor drain screws are tight...
