To Rebuild Petcock Or Not?

That is the question!
When I went to remove my tank I pulled the fuel lines and it was a steady pour, I did not bother to turn the petcock off because I had read where it was vacuum operated. I then turned it off and still had a steady drip occuring. Now I have been riding it as it is and was just curious if it was something that I should buy a rebuild kit for soon or just wait till next winter?

I'm not positive on this, but it won't be a problem unless you need to remove the lines from the tank. At least I did it a whole summer without knowing that gas wasn't supposed to pour down when I took the tank off.

so your still riding it with a leaking petcock? my figuring is if you can still start it and ride around it may not be that bad of a leak. that being said it may get worse and if it sits will seep past the rings and contaminate your oil.

The rebuild kit is like $30 and it takes maybe an hour (including pulling the tank and putting it back on). Doesn't really seem "winter project" worthy.

To me the problem seems so minimal that it would be a winter project or at least a 3day rain event seeing that I do have other projects such as a vehicle restoration that takes up most of my time.
I figure that since it is allowing fuel through it is acceptable, granted not ideal since it is originally designed to be vacuum operated, but still operational and much better than the opposite.

As long as the float valves in your carbs are in good shape you shouldn't have a problem.

If one should happen to stick open things could get ugly, but it really isn't all that common for it to happen......

Ok I read his thread and ordered the repair kit. The kit says
Note: Does not include plastic diaphragm spacer block
Is this something I will need or can I use the one on it?

You can use the old one. It's a little plastic ring that attaches to two diaphragms- you just pull them out of it and put the new ones in.

I know it's a freak occurrence but if your petcock is bad and your floats don't seal and your stator is arcing things can get real interesting real quick.

This OEM part set should be all you need for a rebuild:

Part Number: 16953-ML0-034
Description: COVER SET, PETCOCK for Honda

It has all of the gaskets and such in there. Around 30 bucks.

The aftermarket ones are hit and miss for quality.
