Maybe need a valve adjustment? Help.

Hey guys, new to the thread and riding alike!
I've had plenty of dirt bikes, snowmobiles and quads throughout my life so I have a pretty good idea of how carb'd engines run.
I just bought myself a 2011 Ninja 250r SE ! It has 1,300 on her and she is a beaut.
The only thing I've noticed is that there is a bit of lag, or bogginess, every time I get on it. Even in 1st. I know 250's don't have a ton of power but I feel like I should be getting a bit better throttle response than what I'm getting now. The bike has been jetted with a DynoJet stage 2 kit and he has not gotten the valves adjusted so I'm sure that has a pretty big part in it.
I guess I'm asking if anyone has a write-up on the best way to adjust them myself, and anything else that would help the throttle response out a little bit.
Thanks guys! I'm really excited to be a part of the 250 community and a forum such as this.

2011 Kawasaki Ninja 250R Special Edition

K&N Air Filter
Yoshi Fender Delete
Integrated Taillight
Driven D3 Grips and Bar Ends
And I peeled a few of the stickers off.

Just google "ninja 250 valve shim" theres some good writes ups on it. You'll need a decent set of feeler guages and a micrometer for measuring shims. Precison Shims in Austrailia has a superb selection of shims, 5 bucks a piece, cheap shipping. Im doing mine. Hardest part is getting your hands in there. Get a feeler guage that reads as low as .003 with .001 increments. Mine has a .0015 guage so i can double the leaves up for an even more precise measurement. New gen 250's use a shim and bucket design, where as the old ones had set screws and locknuts. Any questions, ask
