I have a Twin Cam 96” and I am using a S&S Super E carb, teardrop air cleaner with Vance & Hines Bigshots. I put about 100 miles on it and it seems to be running good and has good throttle response. But, I do get a lot of popping on decel. I’m running a .031 intermediate jet and a .076 main jet. Could this be too rich?
Thanks for any help.

Also check for exhaust leaks.

Here is my understanding of decel pop. You are running somewhat rich and the unburned fuel collects in the exhaust pipe and muffler. When you close the throttle you get a lean spike and that ignites the unburnt fuel in the exhaust system.
