Fuel leak and valve cover leak

Postby zvacman » Mon May 24, 2010 4:21 pm



I just picked up a 1982 GL1100 Interstate (9948 miles)! When I picked it up it wasn't leaking fuel, after 90 miles in the back of the truck I stopped and filled it up (about 3 gallons). I drove 5 miles home and it was leaking like a SOB. The petcock was shut off by the way, the fuel was coming from higher up. Any common things I should check first?
Secondly, the previous owner wanted to check the valves and when he put the covers back on he used what looks to be silicone. How hard is it to remove these covers and install the proper gaskets?
Any help would be appreciated this is my first Goldwing.

There really is nothing higher up from the petcock other than the fuel tank itself. If that's leaking, its a job to get it out to replace it.

As far as the valve covers, they are fairly simple. Just look at the relevant parts of this how-to: viewtopic.php?f=11&t=2229

Possible update. I turned the fuel off and it seems to have stopped leaking. The previous owner had the carbs off and claimed to have had them rebuilt. I can't see where the fuel was coming from but it is running down the right side of the engine.

Stuck carburetor float is usually the culprit, unless some fuel line has broken - check the fuel filter and its fittings.

I took the seat off last night and noticed the previous owner must have taken the fuel level sensor out at some time and totally boogered up the retainer putting it back in. Is there an aftermarket sensor available for my bike?

Not likely, but I'm sure you could find a used part online if you can't fix the one you have.

I looked for a thread about that sensor and couldn't find one. Does anyone know anything about fixing the sensor? Voltage readings, resistance, ect.

Thanks, Z

The fuel sensor runs from the 7 volt regulator that also powers the temperature sensor. You should be seeing a regulated 7 volts at the fuel sensor. From the 1100 service manual:

Fuel gauge sensor resisitance:
75-80 ohms at bottom of float travel
6-10 ohms at top of float travel

Measured at the sensor connectors I'm assuming. I oredered a Genuine Honda service manual today so by next week I should be a little less of a pain in the butt.
