Help guys, I recently noticed my fuel petcock leaking on the 98. I have never rebuilt one. Is it hard?Are there instructions anywhere? My moto shop has akit to rebuild it for 30.98. Is that about right? I appreciate all of the help ....maybe one day I can return the favor.

The vacuum petcocks do tend to leak if the diaphragm gets holed. It only takes a pinhole in it to emit strong gasoline odors. Rebuilding isn't a difficult job, you can look on Motogrid or Honda Directline on the internet to see what prices are so you can judge your dealer's mark up.

When I was younger and stupider I had a stealer replace one without asking the price and they ripped me one by charging $130. for the part. Later I checked online line and the rebuild kit was $12 and change. If I remember correctly there is only a couple rubber seals and a spring to rebuild the thing.

I got a rebuild kit for $13.00 + shipping from here: http://tinyurl.com/bc5c9h

I was running rich, and wanted to eliminate a potential problem.

. . . . . turns out - my bike doesn't seem to have a petcock at all.

All Goldwings up through the 1500 have petcocks. The 1500 is different in that it's automatically operated by vacuum and it's located on top of the tank forward of the filler neck.

Thanks for your help guys. I went to the web site and looked at the rebuild kits for the fuel petcock. None were for a 1998 SE Goldwing... only 91-95
Any other ideas?

2places you can get the K & L kits for about 24 bucks.



I did mine with one and have no problems



Just make sure you get the diaphragm sitting flat with the spring tension when you put the two halves back together.

I just looked up the part numbers for the petcock at Motogrid and Honda Direct Line. On both sites the part number for a 1990 petcock is the same as for a 1998 one. I think a rebuild kit for any 1990-2000 1500 would be the same. Probably the same all the way back to '88 but I didn't check back that far.

Will the 1500 kit also fit the '84 GL1200?

Extracho - Nope, the 1200's petcock is much different.



Wingnumberone - Your bike looks quite a bit different around the fuel filler than mine does. The spill tray is different too. I'm attaching a drawing from Motogrid showing the vacuum petcock, item #4. The drawings at Honda Direct Line are the same for all years of 1500s.

I've seen that sketch, and others like it - and both manuals I've checked show the petcock. My '88 just doesn't have it. The line from the fuel filter goes directly to the tee for the carbs. It looks like all factory line, too - like the valve was never there.

I suspect a PO removed the valve. If you have a service manual, you should be able to trace where the vacuum line came from to operate the vacuum petcock.

I have now ordered the 1988-1990 rebuild kit. Hope it works... I will post as soon as I get it rebuilt... Thanks for everything, guys.

Another thread has been started on this problem here and it contains some parts and additional links. That thread mentions this thread as a reference because of the diagram up above.

I'm tying the two threads together for future readers.

2nd thread:
http://www.goldwingfacts.com/forums/forum1/77649-2.html

start reading at post 21 for the fix. Start reading at Post #1 for the symptoms, probably sounds like your problem if you are reading here.

Post #24 has the thread links and the parts needed to fix it.

Mine is leaking too. From the contents of the repair kit it looks like a diafram and spring, pretty easy fix. Have you done yours? Any tips? I just ordered my rebuild kit Friday.



Thanks

For all interested, a re-assembly procedure (got it from another wing site):

There is a trick to putting it back together. The first two pieces you want to join together are the two aft pieces, the end piece that the spring touches, and the piece that the large diaphragm rests on.
With the large diaphragm laying on the metal piece, lay it on a clean flat table. Place the spring on the diaphragm, the hold it firmly on the table and push the end piece down to seal the diaphragm. Since your holding it firmly against the table, the spring won’t push the diaphragm through the hole.
Now you have to lift that assembly off the table, holding it firmly together and mate it with the front piece. While holding everything together, put the screws in to hold everything in place.
