I was warming up my bike to ride to work, but forgot to open the petcock. While inside, it died as it should. cooldude I opened it and restarted, all of a sudden fuel started pissing out all over the left side of the engine. Sounds like one or more stuck float valves?
Lost a beautiful day to ride.....

Sounds more like fuel rail o-rings. Stuck float valves would send gas to a cylinder (hydrolock) or out the drain tubes. Many have reported that this can self correct if the bike was sitting dry and the seals just need to soak in gas a while.

Well, I had just a few minutes to look at it today. I asked my wife to bump the start switch while I looked under the tank. She just bumped the switch, and thunk. Hydrolock. No damage, no ugly sounds. So I'll be ripping and tearing in the next week or so. Probably desmog while I'm in there....

I would back out of the garage and pull all the plugs and bump starter. the hydrolock cylinder will spray the fuel out of it and you'll know which float is stuck. If it is number six cylinder fuel could have got in there by way of the vaccum tube. good luck. Good luck.

Thank you Chris and Bubs.....that's my plan...I'll probably just bite the bullet and do a good carb rebuild while I have it apart. Maybe a Dan-Mark. I need to back and do the research again. Lots of great info here.
I was just looking at Redeye's website. He mentions a full carb seal kit, but I couldn't find it. I'll clean my glasses and look again....

Bob, I would recommend this model Dan Marc. It has the .250 orifice versus the .100. http://www.dan-marc.com/79-afc1211412.html |

Not sure why this Multi-Fuel Shut-Off Valve is referred to as a (Dan Marc). He does not make it. It is manufactured by: AFC-Advanced Fuel Components, Inc. 300 Wooley Drive Marshall, MI 49068 The Model 111 that many have used, and / or other models can be purchased from: Century Fuel Products 5715 South Sheldon Road Canton, Michigan 48188 http://www.centuryfuelproducts.com/catalogsearch/result/?q=Fuel+Shut-Off+Valve |

If you have fuel in the cylinder, I would get it out as fast as I could, before it leaks into the oil.

Thanks Gordon. I'll be able to get to that today.....I was planning to change the oil pretty soon anyway. Perfect timing....  Bob |

Well, I pulled all the plugs and cranked it. Got a pretty good squirt out of #4. My question is, if my problem is leaking fuel tube O-rings, how did the fuel get into the cylinder?
I just had the petcock repaired at Inzane by Bill. Have out over 1000 miles on it since then.
I have a bunch of parts coming from Redeye, will be wrenching next week.

If el shot out of #4, it has NOTHING to do with the fuel rails. You have a float that isn't closing all the way, in #4 carb. You could try carb cleaner and run the bike for a good portion of the tank. The stuff that's holding up the float from closing may wash out. I sure wouldn't rebuild a bunch of carbs just for that  |

I sure wouldn't rebuild a bunch of carbs just for that I agree, but I usually go overboard when I have it apart. I'm pretty generous with Seafoam and Berryman's, so I'm surprised I might have a sticky float valve. I haven't started looking yet, what's a good source for floats and such? |

This solenoid was installed on my ride to Inzane pulling a Timeout camper trailer 3200 miles. Had fuel starvation issues. I replaced it when I got back with a Ehcotech solenoid valve with a 3/8" orifice (.375"). |

Bob, I think you are wise to replace the float valves. There was a guy a while doing a turbo build on a valkyrie that found the springs in them were not as strong as when new. I think it was also confirmed by BonS. I know it's something I will doing one of these days. |

Are you talking about the clip on the valve itself that attaches to the float tab & only attainable with valve @ $19 a piece?

Inside of the needles are little springs that have been found to weaken over the years. Try a search for it, I think it was by Moodyvalk. I would but I've got to get ready for work. |

^^^^^
Thank you for the clarification. I have one (or more?) carb that seems to be getting more fuel than the rest. I smell a tad raw fuel smell from time to time but no effect on mpg. but concerned all the same. Hopefully it won't become a problem before season end.

My Interstate is set up a little rich compared to my Standard. I can smell fuel sometimes also. Something that others have reported that I haven't checked out yet is the fuel filler gasket. I think some guys have put a large o-ring under the gasket to get a better seal. But I do believe Moodyvalks and BonS's assessment of the float needles is valid and should be addressed. After all when you think about how many times those little springs have compressed and decompressed over close to 20 years. It's amazing they have any spring action left at all. |
