i have a 2012 sportster 48. has vance and hines short shots and screamin eagle heavy breather. just got it tuned from the dealer. brought it home and it isnt running right. i start it up and after 15 seconds it starts to "putt" then idles right then putts again. and it stalls. i start it back up and stalls again. so i keep giving it some throttle and its fine. once the bike warms up it runs fine. has anyone had this problem. does anyone have any solutions?

 

what kind of a programmer is on it? HD or something else. I would take it back to dealer if u just paid to have it tuned .obviously they did not check it out, The cold startup is too lean. it need to be enriched so the engine will run correctly till operating temp reached.
