well its getting colder here now, arizona, in the low 70.s in the morning. anyway my carb is spitting back out the carb when cold, in fact it will do that until it gets really warmed up. also it seems doggy taking off from a dead stop. to lean im guessing. i have a S&S Super E.

 

Yes that is a sign of being lean. If the bike didn't do this before you may want to check the intake for vacum leaks, don't forget the VOES, petcock hoses if you have them. Hope this helps.
