will tell what I know but its only at a 100 miles on the 09.
I think the 07 had the flys out as I bought it from a user with 500 miles on it .
I rode it the last 5 months.
The 07 had a little better take off and sounded louder (fly out maybe )
The stock 09 springs are set way better for normal driving as the 07 (1st owner) had suspenision set pretty hard . which works for me as I am one of the older big guys who cant tuck behind the shield like a 12 year old girl anyway LOL
The new 09 is way smoother on take off and as I am still doing break in I havnt really opened it up yet so cannot compare higher speeds .
new soft notes and less noise in genral.
07 had a little more low end or sounded like it did.
the 09 is no slouch any way you look at it .
I miss my grip puppies badly as I have big hands and both the 07 and the 09 have just a slight tingle at highway speeds to my right hand and the grip puppies took care of that .
Thats about it for now but since I rode the 07 in the morning and the 09 in the afternoon those are the biggest differences I could talk about so far .
hope that helps
Did you have any thing you wanted to know for certain as they really havnt changed that much .
As far as I know maybe the flys open a little sooner and they(kaw) changed the mapping a little but its the warrenty and color I was going for with a 09 I am glad I can and did swap. nothing wrong with the 07 but the 09 now has a four year warrenty and new tires with a color I like better . I didnt loose to much on my trade in as they are hurting for new bike sales right now so they did a bit under retail and discounted the four year warrenty pretty good also .
I would say do it if you are likeing the newer colors and out of warrenty as its a piece of mind thing also as I dont want to be paying for any repairs in the next year or three as its uncertain times for us all .
I cant say theres a huge difference in performance between the years.
The numbers I read are only a few more HP and flys open a little sooner if this is your main goal I would stay with what you have and mod it .
