Sputtering and popping under load
I have a 1991 Heritage that made a poping noise and died on the freeway. It would not re-start after that. I took it in and the mechanic found that the ignition module was bad. It was replaced with a Dynatek 2000P and I was told that eveything was fine.
Now when it is cold I pull out the choke and the bike starts right up. After a bit I put the choke in and it idles fine. But when I accelerate from a light it sputters and pops, if I let off the throttle I can baby it up to speed.
After the bike runs for a little bit and gets warm the problem seems to go away.
I found that the switches on the new module were set completly wrong, they should have been all off but they were all on. Changed the switch settings and I thought I had fixed the problem but the engine must have still been warm.
I am mechanical enough to change parts or check things but I lack the experience to diagnose issues. Please help.

Well you are now in the Diagnose Mode like it or not.
Double check the last couple of things you did. Trouble will probably be in that area.
Ignition sounds like a likely thing.
As long as its not the fuel system.
