I don't think the bike pictured in the top (blue tank, red strip) is worth $2,000.
It appears to be a fairly stock CB with a brat seat pad (cheap, maybe $100), donor clip ons (terrible handling and interference with the tank ($50), a cheap MAC exhaust with pipe wrap ($100) plus stock suspension, no rear sets, and rusty fork tubes (notice the rust at the lower triple???).
Whether the motor was bored 3mm or not (hard to prove, but I'd like to see some detailed pictures of the motor and screws to determine what's been touched, what has not been before I'd accept that idea. Pods make it look cool, but probably jetted badly and no performance improvement. The 3mm piston kit is probably a CruzinImage kit that runs $120, and lowers the compression in the motor. I'd suspect a stock cam.
The brakes appear to be stock, speedo looks like a stock unit (wheres the tach???).
$1200 if you want it badly, because you'll need some money left over to get it to run right. Like cleaning the carbs, replacing leaking gaskets (guarantee it leaks somewhere) and performing the complete 3,000 Maintenance Service.
If its your first bike, clip-ons with stock pegs is about the worst riding posture you can create. Uncomfortable, poor geometry, and overall a hodge podge. The 550 is a decent bike to learn on, but you want different bars and rear sets, and for God's sake, ditch that skateboard seat!!! It is not comfortable, terrible for handling, and overall a very likely interference with the rear tire
