Gas leak, rear of motor/clutch

Postby twaggoner » Mon Aug 06, 2012 10:28 pm



I rode my 77 GL1000 Saturday and came home today to see fuel leaking out the lower rear of the motor. I have attached two pics to show where. If I am correct, it is the clutch assembly area where the fuel is leaking from. However, I checked to ensure that the lever on the tank was off and pulled the fuel line completely off of the fuel pump and it still ran out the lower rear area.

If I need to put the bike on the jack stand for some serious rebuild, so be it. It is a 35, or so, year old bike and I do not have any clue to how it sat before I bought it and started working on it. I have rebuilt the carbs with a kit from Randaks and one of them is leaking so I am going to have to put some time into it anyway. I just would like to know how gas is leaking from the lower rear, by the clutch, I think, and what will it take to fix it.

I am always very great full for all of the responses that I receive for all of you Goldwing junkies ;-)

well, my first thought was the fuel tank has a leak. it sits right over that area, as it comes up to the fill spout.

Hi. Have a look where the clutch cable passes the tank. On the right hand side. There may be a rust hole where they touch. If the drip is there only when the tank is full. It could be running down the cable into the clutch assembly area then out the bottom

Put a drop of oil in the fuel and when the gasoline evaporates you should be able to trace where it starts leaking. To have gasoline coming out of the clutch adjustment cover seems strange, if it is coming out there it must be going in there via a leak on the fuel tank????

To all that replied... Thank You very much. I put the bike and the Jack-stand today and will begin putting to use the nuggets of experience that you guys gave me. I will keep ya posted on the outcome. Oh... I am am short on cash and was wondering if "Tank Patch" is worth trying. I would hate to have to wait to by a new tank but I do not want to patch it, get it together, ride two or three times and have it leak again. Any thought on patching a (small) hole?

Look at the tank drain bolt, they are a pita to seal and if it has every been opened then just maybe it is the source. I used a seal washer to finally get mine to stop weeping after I opened it to drain the tank last winter. I will not open one again unless it already is weeping.

That stuff they sell in the auto parts stores for "patching " a leaking fuel tank is short term at best, and makes for a much harder proper repair. If it were mine , I would pull it out(not too bad a job) and have a radiator shop repair it proper. you will need to rinse it with lots of water , then get it dry, or they can't/wont touch it.
Permanantly repaired and forget it, ride ride ride!

Buy the way , there isn't any "new' tanks for these bikes. You could get a good used one, but you might have to look at a lot of them , till you find one worth having.

Twaggener I live in North Texas and I am a pretty good TIG welder. If you are near me and have only a small hole in the tank I'm pretty sure I could either fill it in with filler or scab a patch of similar material over it. As an alternative, just the other day I found a website whose specialty was actually rebuilding Goldwing gas tanks. If you want me to help I need the tank bone dry and free of heavy fumes in order to weld. Otherwise I can do a little backtracking and find that website who rebuilds them and post it here. Tom

OK!!! to all of my Goldwing junkies that was so good to reply to my question... My front left carb was DUMPING fuel into the cylinder. Apparently, when I rebuilt the carbs I did not get something seated correctly so, I have pulled them and am attempting to find the problem. Thank you all for your advice and help.

Shortly after I had purchased my first wing (79 1000) I went down to my shop and sat on the bike, hit the starter button. It kinda grunted and nothing more. In my mind I asked myself "What the heck?"

Just to be sure I removed the spark plugs and looked inside with a flashlight. Couldn't see a thing. Again I hit the starter button, this time with the plugs out.

This time gasoline shot out of the spark plug holes on the left side and splashed against my workshop wall. The engine spun freely under the power of the starter motor.

I turned the fuel petcock off, came into the house and ordered four new carb kits. That's the day I started turning the petcock off when not riding just as I had been doing on British bikes for several decades.

That was ten years ago.

Turning off the petcock is excellent advice. I am sure that I had turned off the petcock after arriving home. I am pretty sure that on the ride in to work and on the way home was when the damage was done. However, I will be extra sure to check and shut it off whenever I am not riding. You Guys all Rock!!!

I need to keep it simple.

START has 5 letters and means the Stand is up, the peTcock is on, the Air choke is on, the electRic kill switch is on, and the igniTion is keyed to run.

STOP has 4 letters and means the Stand is down, the peTcock is off, the engine is Off, and the transmission is in gear (Park mode).
