Popping back firing

Decel pop won't hurt the bike at all. In fact, it probably does that from the factory but the pipes are too quiet to hear it.
It could also be from loose exhaust header nuts, as said above. Easy enough to check.
If you are actually getting a backfire (not the same as decel pop) that is less likely to be happening, and is often due to intake leaks. Also not hard to check.
There are tons of tuner threads here, look around and do some reading on them, see what makes sense to you.

thanks for clarifying that with me, so I guess its just decel pops im getting no backfires, definitely doing my reads on tuners

It annoyed me at first but now I'm used to it. I kinda like it, in fact.
It's not terrible, but it's there.
Almost sounds like a P-47 coming in for a landing after a day of swatting Bf-109's out of the air.
Because, basically, that's what our engines are...... Two cylinders out of an old Radial Aircraft Engine....

Also a lean condition will cause a decel pop which is almost always the case. As stated earlier un burnt fuel will also cause a pop but it usually will only pop once and mostly if you snap of the throttle. Sometimes you will have flames out of the pipe. A good example is a roadrace car getting out of the throttle for a corner. Here is a vid of one of my bikes I built on a dyno. At about the 56 sec mark the throttle gets snapped off and you will see a nice blue flame come out of the exhaust, that's a fat pop. There was a real good tune on that bike. No it's not a Harley, but I've built some fast bikes. That was a 4th gear pull.

If you are sure you have no leaks, you have 4 options.
1. Try the XIEDs which might correct the issue. Then again, they might not. You're rolling the dice.
2. Try some Thunder Torque inserts. Same deal as the XIEDs. Might or might not work.
3. Buy a tuner (I like PV). With a proper map, your popping will disappear.
4. Deal with the pop.
Edit: Add one more option. Buy a Dobeck TFI injector tuner. It'll work, but it's almost as much $ as a tuner.
