The engine is running lean. I thought the guy I bought the bike from said he adjusted it, if he did, it wasn't done how you are supposed to do it. The main way to do it is to adjust the Fuel/Air Mixture screw.
Here is a picture of the Adjuster screw before the little cap on it is taken off.
Here is a picture of an inserted sheet metal screw to get the cap out if needed. When I did it mine just flew out when I got to the bolt.
The adjuster screw is that Giant thing sticking out, you are actually looking at the bottom of the Carburator.
I may end up needing to rejet the Carburator. Hopefully that is not so, although it will not require all that much more work than getting to the adjuster screw and cleaning out the float bowl.
If I do rejet it,I might go with a 47 pilot jet and a 180 main jet. That is supposed to be good for the Twin Cam, 45 and 170 for an EVO. I will be calling up Harley again tomorrow to see what the stock sizes are, I don't want to pull it apart at home since I wont then have any way to get the bike somewhere that could do work if needed. And I don't have all the proper tools to be messing around with a Carburator.
Oh, and here are three sites that might be of some help.

PS. I'll try to get some pictures of when I do the work.
