Default 2010 EC300 Factory Jetting Specs - WTF?

I posted before about a new 2010 EC300 that I recently took deliver of. I've had a chance to plow into the carb and here are the factory settings:

Slide: #7
Needle: N1EF - Top clip (leanest)
Main: 175
Pilot Jet: 40
Air Screw: 5 1/4 out

WTF? Kinda seems like they just bolted on the carb as it came out of the box from Japan with no thought as to set-up for the bike or where it was going. The needle clip and air screw settings make no sense.

Based on my searches on this site and my locale (600' ASL, average riding temp 20C) I think it's way lean. I've ordered a needle (CCK, it seems a popular choice), and some fatter main and pilot jets. Won't really be able to ride the bike for a few months, as it's pretty much full on winter here at present.

Does it sound like I'm on the right track regarding the jetting?

Otherwise, I'm super impressed with the bike and can't wait to ride it for real -I'm thinking a trip to Georgia or Florida this winter is gonna be must!
