The dealer is not interested.
The bike is set up very lean to meet emissions standards. Any of them will benefit from larger jets. It's probably running too lean.

1.What?

2.What?
You charged the battery off of the battery charger with a trickle charge. The battery wouldn't charge while you're riding, because your alternator took a cr@p.
(Sorry if I seem gruff, but I'm an old biker, and Harleys are all I ride. I'm also a Harley mechanic.
Shhhh! I don't want that to get around! lol!)

3.Battery is at 13.4 volts now? What is the specific gravity of the acid in each cell? Don't have a hydrometer? Do you have a load tester? No? Since you measured the voltage, do you have a multimeter?

Test the voltage with the bike running. It should be around 14.6 volts when charging, less with the battery fully charged.
Don't get the correct reading, then you better look at alternator replacement. (Regulator is built in)

SOURCE: front fork steering head bearings appear to be too lose...

Tighten the head bearings as per your manual.
