V&H Cruzers sound bogged down?

I just got done ear shaving and rejetting the carbs and now my V&H cruzers sound really bogged down and poppy(not backfire just a ticking popping sound). Prior to the earahave and rejet I marbled and there was a little bit of popping on deceleration but the exhaust sounded really throaty and deep, it sounded great. I have the fuel mix screws turned out 2 1/2 turns and I did notice some of the packing coming out of the left exhaust which I feel is the ticking popping sound idk though. I would like to recover that throaty sound as this muffled sound is reminding me of the stock exhaust, kinda like a lawn mower. Maybe I need to readjust the carbs? At idle it sounds like the engine is about to stop but it doesn't, just slowly rolls. Any thoughts would be greatly appreciated.

What's the jet numbers?

Is it truly bogging or it just sounds funny?

If the jets are big enough, it could be the loose packing causing some extra racket. Ripping the packing out would probably make them even more raspy.

Raising the needles one notch may make a difference, but it depends on what you're really hearing. If it's not lean at all, this probably won't help.

Idle spec is 1100 +/-50 rpm, I think, could be 1000 +/- 50. Have noticed some VNs sounding thumpy at idle with louder pipes, like an atv with aftermarket pipe.

I've got 142.5 & 40's. 2 shims. I think I will take out the packing. I read about setting rpm to 1000 then going to screws and adjusting till rpms drop and bring it back up again and did that when I marbled it but at 2.5 turns on each after the ear shave it had no pop on deceleration so I left it as such but I think I should try and adjust them now?
