Hey Guys, I had the old hydro lock on the rt front cyc cleared it and it started right up and sounded fine, thank God! question is have any of you heard of it being a one time deal like something caught in the needle and seat on that carb or am I just hopefully dreaming? Hate the thought of having to rebuild the carbs and probably the fuel valve also thanks for your opinion guys much appreciated! Jym...

I can understand your dislike of rebuilding the carbs. The petcock is a piece of cake. But imagine your dislike of replacing the starter gear and possibly rear case. Not to mention having to do the carbs anyway.

Reminds me of the old Fram commercials...."You can pay me now, or pay me later". Meathead has it right. I'd also install a Dan-marc fuel shut off valve for good measure, but that's me.

My friend went through the same thought process. Fix it or it will happen again.

Your real problem is with the fuel petcock. This is the issue that needs to be solved.
Regarding the carburetor: You can drain the float bowl or take the float bowl off the offending carburetor to clear any crud that may have caused the needle to malfunction.
Note that as long as your fuel supply is shut off properly you cannot have a hydrolock event.
I don't see where you need to r&r the carburetors simply because the fuel petcock malfunctioned, and besides, the needle valve leaking may simply be a transient event.

The Carbs really aren't that hard to do, while your at it desmog so you have more space for the fuel shutoff solenoid. You can find the float valves on amazon most of the carb gaskets on Redeye Technical and rebuild coverset for the petcock or new pringle shutoff.

Potentially dangerous to ignore the carb work as part of the repair to prevent another lock. The issue on the bike I fixed was with the float, not the needle valve. If the float/ needle valve are not shutting gas off it would be much easier for it to happen again. |

The float had deformed just enough so that when it rose up with filling gas it lost contact with the needle valve. We even tested it wit the new needle valves. Absolutely no contact as the bowl got full. |

My 2 cents: Get a Dan Mark fuel cutoff solenoid. $30 insurance against hydro-lock. I had my own hydro-lock happen. We had trailered to Colorado and back and the change in altitude caused the petcock to trigger flooding one cylinder. Thankfully, it didn't break anything when we tried to start it. I feel very good about having the electric fuel cutoff. good info here. http://www.horseapple.com/Valkyrie/Tech_Tips/Fuel_Shutoff/fuel_shutoff.html |

Pressure change. We went from a high altitude (10,000 feet, lower atmospheric pressure), to a higher pressure at 760 feet. I suspect that created a pressure differential on the petcock diaphragm and made it leak. I could be wrong, but that was the only time it had ever done it.
When we took it apart, everything was fine inside. Adding the fuel solenoid is just added insurance.

Always turn the fuel off when hauling your bike on a trailer, back of truck etc. The bouncing will cause any carbureted engine to flood.
