Could really use some help, will buy beer
I've been battling this problem ever since buying my bike in 2018.
Whenever coming to a stop, it gives out a thick fuel smell. Enough to make riders behind my choke and my own eyes to start watering :O
It feels like it is throwing this smell the moment it comes to a dead stop.
I ride everyday in the city and light to light. It seems to be less of a smell if I am out on the freeway cruising and then coming to a stop.
Been back and forth with Jamie but we couldn't quite seem to get it to go away even with his suggestions.
I even bit the bullet and bought an SE aluminium manifold as he was thinking my stock one was warped.
Would someone please help?
I do not have the stock tune to revert to, so I can't test if it's the pipe that's the problem.
I am running these on the 2018 Heritage Classic
1) cobra neighbour hater slip ons
2) SE extreme ventilator intake
3) SE intake manifold (aluminium)
4) PV tuner (map attached - https://wetransfer.com/downloads/f9f...5195025/bac1bf)
I will be sending beer to whoever helps to solve this, it's really been the bane of my riding but I am sure there is a solution out there

at idle your lambda is .981 which should be lean enough to not have any fuel smell, I think that this lambda will take you out of closed loop and then if your VE is off you could be rich.
Any chance you have a fuel leak somewhere?
Just read that .981 will put you in closed loop, so you should be no smell from exhaust.

Are you running the head breather vents to atmosphere instead of back into the intake? That can be a cause of a very strong smell at idle.
Also - I have seen O2 sensors get flaky at the edge of the closed loop range when trying to set them as max rich (funny because we are talking 1/2 a fuel point) . You could try setting the lambda to 1 and see if the problem goes away.

Hi all,
thanks for the input.
Fellow forum members are the best!
I got help from Ke5rbd who took a look at my map & reduced the deceleration enleanment.
Loaded it & it still smells, although less, or maybe I am just mentally telling myself there is a change.
Either way, I did take the suggestion of riding in log mode and will be sending him a log.
Also did a test where I watched the gauge during auto tune. It seems the smell it thrown when I come to a stop and the VE table is in the 1250 rpm and 0 tps mode.
Bike runs amazing and even w the reduce decel that Ke5rbd did on the map, no popping.
Just an annoying stink!!!

Is your air filter wet? I bet those pipes have a **** ton of reversion. If that's the case, you're gonna have to pull fuel from that area.
A neighbor had a soaked air filter from that exhaust and reversion but he was also running performance cams but just a thought. Not the best exhaust performance wise.
The name pretty much says why people run them. Sound not performance.
