Well, I decided to rebuild my fuel shutoff valve with a kit. The kit is very simple containing the two rubber diaphrams and spring. I'm either doing something wrong or the large diaphram is not sealing. I sure don't want to have to buy one from Honda for $169.00! Just hoping someone has some experience with this. Thanks:waving:

Is it leaking fuel, not holding vacuum or just not allowing fuel to flow?

It is easy to reassemble incorrectly. I really do not remember the order but logic would dictate spring first towards vacuum fitting then seal with the metal disc mated to spring and then the smaller seal. With the seal holes lined up, gently squeeze the two halves together and start your screws and tighten.

Sorry, I can not be any more helpful.

The rebuild kits are getting very hard to find. Recently, I had a problem with the petcock on my 1998 1500. I was able to find rebuild kits for the earlier 1500s but not the later ones (not sure what the difference is). Anyway, I wound up ordering a new petcock from Ron Ayres for $118.00. It was worth it to me to spend the money to have my bike back in good shape as I ride every day.

Good luck,
Ed

I rebuilt mine last year so hopefully it will be ok for a long time yet. If it causes problems again I will replace it with one of the electric valves similiar to this one. Certainly a lot cheaper than buying a newvacuum valve.

I used a Mity-Vac on the vacuum port and can get no reading. I did consider the electric petcock but would like to hear more about it from folks using them. There is a tiny grove in the cover and the large diaphragm has a lip on it that looks like it should seat in the grove to seal it thoroughly but the diaphragm is thin and hard to position perfectly. Just wondering if a minute amount of silicon could be used in the grove to hold the diaphragm in place? Thanks for the input! Jeff

Did you use the Valkyrie rebuild kit?

It said 88-89 Honda 1500 Goldwing. It looks identical to what I replaced Stu. How is the valk different? I've heard it's not the same.

It is a different petcock design. Exactly I don't know.

Thanks. When I think of a petcock I was thinking of the lever type that you turn to shut off the fuel.

No silicone Jeff. Tens of thousands of these have been assembled, you can do it too. Just takes a little patience. Get the two halves close enough to start one screw. A vise might be handy here to hold the lower half. Keep the cover level. Three screws and diaphragm holes to go. Rotate the top slightly back and forth with the next screw in the cover to pick up an adjacent threaded hole. You may have to tug a little bit on the diaphragm with a small pair of smooth jaw pliers or a hemostat to line up correctly. Get that one started and move on the next.

Once you get them all started, alternate tightening to bring the cover down evenly.

:smiler: Steady hands and patience is what it takes. I have rebuilt hundreds of carburetors, pumps and valves of all sorts in my day. Some diaphragms line right up and screw together nicely. Others, well now you know.

Just don't get frustrated and rip it. If need be, walk away and tackle it later.

I worked a little Permatex in the groove with a toothpick last time I rebuilt one, and it went together easy. Never had any more trouble with the valve. Check to see that valve holds a vacuum before final mounting.

Well after assembling and disassembling the petcock three times with the new rebuild kit and it not holding any vacuum my neighbor tried it and got it right the first time. I'm back in business. Thanks for the help guys! Jeff:thumbsup:
