Questions about Solid infill/First layers Solid infill

Is it normal for my printer to extrude too much when printing solid infill?

For example my first 3 layers are usually solid and come out a little wider and kinda bumpy but the rest of my print will come out beautiful. or anywhere else it decides it need to have soild infill.

Ill see if i can throw a pic up of something. im printing the GE turbine from Thingiverse right now.
