Leaking carburetor

Postby montgomery63 » Sun Jul 26, 2015 7:39 pm



Out of the blue my GL1100 has started dripping gas from the carburetor onto the top of the engine casing. The source of the drip appears to be near the center of the bike where two parts of the carb assembly come together. Obviously I can't ride the thing without fixing it or getting asbestos riding chaps. Any ideas what has caused this drip to start so suddenly? What's the likely fix? Thanks.

Make sure you always use the petcock to turn off the fuel or you could fill a cylinder with gas and hydro-lock! Sounds like you might be taking the carb rack out in the near future. Try to isolate the leak as well as possible. Turn off the fuel, clean and dry the top of the engine, sprinkle a bit of baby powder or flour on the top and open the gas again. Should show wet spots. Then you know where to investigate if you do need to take the carbs off or not.

Thanks, Rick and Brian. Yep, I always turn off the petcock, and I suspect the seals have finally worn out (just wish it were the end of the riding season!) I can clearly see where the drip is originating, so that part of the mystery is solved. I'm thinking I may have to have the carbs rebuilt since its likely all the seals will start to go.

If you'd like to try this yourself (highly recommended), I found some great pics on another site:
I think you have to register/login to see the pics - well worth it.

There are also tons of other links/videos and you can always ask questions if you get stuck. Also, pretty pricey to have someone else do it...

Good luck whatever you decide!
