Suspension Adjustment for KLX 250 sf '09
I got my baby in June, I am 6'3 and weight 250 pounds, bike has been treating me nice so far (almost 3000km put on it since i got it)
the rear suspension is sagging a little (probably made for someone that weights 170lb)
How do you adjust the rear suspension
bike sits 50 cm from the rear axle to the exhaust , when I'm sitting on it, drops to 41 cm
need to adjust this so my light stop binding people I ride with.
Thanks in advance.

Great user name. Welcome!
There's several threads and instructions on setting your motorcycle sag. Search around...like on youtube: ‪MXWrencher.com - How to Set Your Race Sag‬‏ - YouTube
To do it RIGHT, you may want to re-spring the bike with a spring made for your weight. Otherwise, you will be putting a lot of compression on the stock spring by cranking it down to get the proper ride height, and then you'll be losing a significant amount of travel.

Like you, I am a bigger guy and suffered the same issues when I first got my bike.
Heavier springs are an absolute must have for this bike.
A lot of guys do it themselves but I just took mine to an MX racing shop and had them do it. Heavier springs front and back along with new valving made a huge difference on my bike.
I highly recommend it. Yes, these bikes are designed for someone who weighs 160 pounds.

how bout for 180 LBS?
2009 KLX250SF . I'm 180 LBS. and I have stock suspension. Should I adjust what I have or get a new rear spring and re-valve forks? Also should I bother adjusting sag?

Yes... try to adjust sag.. that will tell you if you need new springs.
You can consult Racetech for suggested springs, front and rear, but I think they run a little heavier than needed. I haven't ridden the SF, but most likely you are close on the rear, and a little weak on the front.
Revalving the forks makes a huge difference off-road, but I can't tell you how that translates to the SF model on the road... I know revalving my Versys forks made a noticable difference in ride quality for me.
