Do a search on here. Lots of info. You need to know whats in it now before you start stabbing at it.

What area are you in? The elevation may make a bit of a difference as well.

Then the first thing I would do is shut off that damn accelerator. It shouldn't be backed out all the way. That's probably whats causing alot of your flat spots on the road when you open the throttle. It's flooding it.

Turn it in till it touchs the pump arm then go for a ride and see what the difference is then if you need back it out 1 turn then ride it then if you need to go a little more then back it out another 1/2 turn but you shouldn't have to back it out more than 2 turns just like S&S states in their instructions.
