Raw fuel out of the exhaust
Hi everyone I'm new here my names mike, so I have a 2016 softail deluxe and I just put samson 36 inch fishtails on it I tuned it per V&H recommendation and it ran good for the first day. The next day I fired it up and smelled fuel and low and behold I was spraying raw fuel out of both pipes!! ALOT OF IT!!! Has anyone had this issue?

thats the strange thing no fault messages, and V&H checked the Fuelpak data and said everything looks correct. They even had me run a super lean map and still pissing raw fuel out

Have you checked for exhaust leaks? Are the O2 sensors tightened?
Loose/leaking exhaust: This can cause a poor ground connection for the sensor or allow fresh air into the exhaust system. If fresh air enters exhaust system, the O2 sensor will read a lean condition, causing the system to go rich.
Inspect the fuel injector and O2 sensor connectors for backed out terminals,
improper mating, inoperative locks, improperly formed or damaged terminals, poor terminal-to-wire connection and damaged harnesses.

are you sure it is fuel or water???
if an O2 went south, there would be codes. now an injector that leaks could be a source as well as fuel pressure but then again for raw fuel to pass, code should be thrown unless this is only a startup pre-warm issue when the ecu ignores sensor inputs and follows base map.

I think bustert is correct. Maybe with drag pipes, but with fishtails it would be really hard to get raw fuel pouring out. Probably a bit of water (condensation) mixed with the fact that it is running a bit rich, making it smell like raw fuel.
It ran good the first day, but this happened ion the 2nd day; me thinks condensation. A test would be to put a small can under the pipe, collect some drips and see if you light it on fire. Yes, do this away from the bike, have extinguisher handy, etc...
