I also bought a new 2010 FX 450, this is what I got with mine, it took a couple weeks. My local dealer is 4hrs away, and shipped it to me when it came in (Thanks 417 Powersports in Springfield Missouri, GREAT Guys to work with!!). The picture in the link below shows the map switch on the right side of the picture. The rubber cover slides off and there is a knob with #'s. Setting #1 is a milder than stock setting #2 is the advanced setting and #3 on to #10 is the stock setting, according to the directions.
I had my dealer install the map switch and an hr meter before I drove down and picked up the bike. They sent the rest last week : ) The bike sounds Niiiiicccccee with the new FMF silencer. Wakes it up too : ) I hope to send off the suspension in a month or so when it gets cold here.
Did they tell/explain the break in procedure? 1 hr oil and filter change and screen clean (it's the bolt next to the drain bolt that has to come out first, then the screen bolt will come out). Then at 3hrs do the same...Then I guess what ever your comfortable with, some guys to it after every 5 hrs, maybe sooner if it were race conditions..
Someone in another thread had talked about an upper screen, might have been TT. Anyway, I couldn't find another screen in the Parts manual, any body know anything about an "upper Screen"? My dealer didn't know of another one..
As far as a hesitation, I think it just may be a little tight, needs to be broken in. Mine maybe has a slight hesitation at idle and then blipped when not warmed up, but it Rips when your riding it after warmed up!!
Happy Riding!! 8)
