Default Lean running 883/ hammer 1250 conversion?

Hey guys, a quick run down of what my issue is. I have an 01 883 that I just did the hammer 1250 basic conversion on. I kept stock heads and stock ignition (just retarded it a little). I put in a 45 pilot and 185 main, the bike HATED the 45, wouldn't stay running unless I was at 1/4 throttle and it was puking black smoke, even with the mixture screw at 2 turns out. I put the 42 pilot back in and it ran much better, except it's running lean (plugs are white) and it's popping and back firing on deceleration, even with the mixture screw about 5 turns out. I asked hammer and they had no idea what could be the issue, said they've never seen a bike not like the 45 pilot like mine did. Any one here have some advice of what may be going on? Thanks in advance
