I have a 2014 fatboy lo with vance and hines big radius pipes and get popping when decelerating. Is this normal?

After I set up my 2013 Fatboy lo with pipes and the works it backfired a lot. Then it settled in after a few months of riding. Sounds cool when it does it.

It shouldn't be popping.

If an exhaust is too free flowing or too short, it will cause popping.


My Thunderheader used to pop on decel until I added a restrictor plate in it to restrict how much air was allowed to enter the exhaust on the reversion pulse.

Do you have a dyno graph with an A/F mixture reading?

Invest in a SESPT and take it to someone who knows how to tune a bike on a dyno. If they know what they're doing, the decel pop will be eliminated.

After the install of my ThunderMAX, my Fat Boy popped a couple of times in deceleration. My indy said it would take up to five rides to get the adaptive tuner to settle in. Seems to be well tuned, now, because it doesn't pop.

Is it loud popping or just talking to you a little? Mine just grumbles and pops quietly. Have to thank the Kalifornia EPA settings.:fitz XIEDS made mine behave. Take a look at your plugs for fun. Little white on center electrode and darker around edges. Rear cylinder may show slightly hotter. Ride Safe

This is how I would describe mine. Since it has plenty of giddy up and I get amazing gas mileage, I'm leaving it alone. I also kind of enjoy the little added noise.
