Leaking fuel
Hey there! I have a 1997 fxdl I bought used about 6 months ago. Just this week it started leaking fuel constantly out of the fuel overflow valve as well as from the hose that connects the two heads. This continues even with the petcock in the off position. It seems to run fine but I haven't ridden it in the past few days since this started. Any help is appreciated! TIA

You have not done anything to the bike or fuel system but fill it up, right?
My son's LR overflows through the atmosphere vent when he overfills since I put on a new tank. I think I might have reversed the vapor valve when I put it all back together or his new gas cap is not vented...not sure which yet, he just told me about it...

Sorry, not the hose. The fuel intake coming from the carburetor. I'm currently trying to clean the inside of the gas tank as i discovered a bunch of rust in there. I'm also waiting on a rebuild kit for the carb. And I'll be replacing the gaskets where the fuel enters the heads. Hoping all that fixes the problem.

that sounds like something is mucked up in the float. My 2001 SG CV-40 vents fuel to the intake and not overboard like a CV 44. I had the float stick once and damn near hydraulic-lock my cylinder. I caught it when it stalled on the initial crank over and pulled the plugs and blew a lot of gas out. Damn lucky I didn't blow a head gasket or damage the heads. Since then, I replaced the valve, inspected and adjusted the float...and now turn off the petcock.
