More fuel. How you get there? Depends on the bike - carbed or EFI?

Stock exhaust and air filter or higher flow at each end?

Stock air filter and screaming Eagle slip on mufflers that were installed by dealer when the bike was new.After looking at the first set of plug pictures on themac5150' s post my plugs seem pretty normal.Have read many posts now that the newer Harley's run lean right from from factory so Knowing me I am worrying over nothing.
