I reset the idle control and set the tps. I still hear a pop after I let off a full throttle burp. I can test ride it on the weekend, but I think if itís popping itís still going to backfire. What else do I check? I charged the kimpex battery to 12.7V it seems to be holding a charge.

Did you leave the spark arrestor out when you welded the access cover back on?
Keep your muffler stock!
550 EFI's run like crap if you do any muffler mods.
