My 2006 Ultra Classic is giving me hell. There is a loud sucking/blowing noise, and the engine bogs down to almost dying. This only happens when I get moving after the bike has sat for a while. It happens about 2 to 3 times until I really get moving. I let the bike warm up for approx. 2 to 3 minutes before I start riding. Can anyone give me any suggestions on what may be going on?

 

Start the bike and look inside the fuel tank with a flashlight for any signs of in-tank fuel line leakage. It will be obvious if you see a fuel mist in the tank, tou will also hear the hissing.
That's where I would begin.

 

Sounds like a hole in the fuel line inside the tank. Easy enough to fix once you get the sumbitch out of the tank. I had a helluva time with my 03 Road King
