Default Popping when shifting up!

Okay the other day my bike was popping when I was shifting up. My friend noticed and mentioned. I tried to ignore it.
I went to the harley dealer and they ofcourse werent much help.
So I went to a little motorcycle shop that opened up a few months ago, he used to be the lead mechanic at my harley shop.
Anyways I spoke to him about it and he went to check my computer for free but couldnt read it. He looked at my exhaust and said take out the set screws in the tips and re-place them with inch or inch and a half ones to create a little back pressure. Said it wouldnt change the performance much.
So I went and bought them. It helped a little and didnt notice any performance issues. And it cost me a dollar.
I have the vance and hines big shot staggards. It also seemed to help out with the splash sound.
Does anyone have any other ideas or maybe this will help some of you.

The pop is a lean condition, you said you have pipes efi or carb?? Do you have have a SE a/c system?? Have you added a carb kit or a PCIIIR/ PCIIIUSB or a SERT?? Ading back pressure to a EFI system will not help much if you have not upgrade the ECM program.

It is EFI with the screamin eagle kit. But vance and hines exhaust. Not other performance mods. ( Synthetic oil motor only)

I dont mind a little but would like to richen it up some for the cheapest way. Also the back pressure was to come from these new screws.

I had the same problem and all I had to do was install a power commander http://www.powercommander.com/
Its a real easy job, takes out 15 minutes and you will be shocked at how much better your bike will run. I suggest the power commander usb model.

I really want to do the power comander. However I do not have the cash nor a lap top to accomplish this. Plus do you use just a plain program or do you have to make one specific?
i wish there was someone close to me or a buisness i could pay for this service for cheaper.

With the usb model you dont have to be at the bike, just plug it in to your desktop and load one of the maps from the website.
