It's running out of the 3&4 carb. I have already checked the floats and they seem fine. I haven't dunked the carbs but I have sprayed them with carb cleaner. Please help
 
Have you verified the petcock is working properly? What bike is this for?

You're going to want to pull them apart and dip them properly which will entail replacing orings (get them at www.cycleorings.com), the proper dip (Berryman's in the gallon can with the basket), and 4 days (one per carb). Look at this site (you'll get the official welcome later), http://members.dslextreme.com/users/bikecliff for instructions on doing this.
 
pull your gas line of your fuel petcock and see if it drips it should not trip if the engine is not running
 
its most likely the needle and seat the needle is probley worn out and letting the gas get buy

Hi Mr. Calebduncan1",

Overflowing Carbs

Then start with the basics; properly clean the carbs, fix the air intake system, adjust the valves, etc. It's all in the maintenance lists in your "mega-welcome". Skipping steps or taking shortcuts will be frustrating at best, dangerous at worst. You can't slap a band-aid on a 30 year old bike that has been neglected for 20 years. All of the maintenance has to be properly performed. Check out all of the information in the links below. :)

If you are here you probably have a 30 year old motorcycle that needs about 20 years worth of maintenance. You'll find all kinds of helpful tips, procedures, manuals, diagrams, "how-to" guides, etc, in the links below. Let's get started.

Let me dump a TON of information on you and share some GS lovin'. :D

I just stopped by to welcome you to the forum in my own, special way.

Might be a problem!!!! What style petcock do you have- lever or leverless? What bike/model/year is this- put in signature to aid us old folks.
 
Hi,

I'm assuming that you've read this:

Overflowing Carbs

Read this too:

Then read all of the information in the other links I've given you. Your motorcycling life will be better for it. :)

It's a 82 gs750L and it has a lever. I'm going to order a petcock just to make sure. What website has the most gs parts?
 
make sure you do an oil change after you get this sorted out, you don't want to risk running the bike on gas washed oil.. check your oil level and see if it's higher than it was..
 
plugged vent ports can cause this also. Put a piece of tubing on the vent thats on carb 4 and see if you can blow air into the carbs..
 
First I would like to thank everyone for the help!
Here is a update I got it to stop leaking and I also got it to run now!!
But as soon as I give it has it falls on its face, acting like not enough fuel.
It has a Vance and Hines header back and airpods. I've already adjusted the air fuel ALOT, do I need to stick a stage 3 jet kit in it?
 
Hi,

From your "mega-welcome". Refer to #4.

Reading all of the information given you will save you a lot of time and frustration.


Thank you for your indulgence,

Full tear down and dipping ( 24 HRS per carb body..2 bodies in the can at the same time) Internals also get a 24 HR dipping. Poke all the holes with a fine wire and be sure to get the one at the tip of the pilot screws.

New orings from cycleorings.com

Lube orings with some grease or vaseline when installing the screws.

Proper float hts

Valves adjusted

Vacuum gauge sync once all maintenance is done and its back running.

Check timing.
