Your riding level, weight and feel for detail will influence whether you'll be content with stock set-up or not.
I've taken issue with, power(torque mostly), steering(slow and unplanted) and suspension(harsh and evil).
The 1st things you should do prior to strapping on the brain bucket.
Apply thread-lock to the upper shock bolt, grease everything(not lower shock heim joint), scrap the rubber and install Michelin M or S12's and a must, DIAL THE JETTING. Very serious stuff concerning the 200.
Jetting: 42pilot/175main/DDK @ #3 groove. Be prepared to order the needle and wait, but well worth it(Sudco.com). I've spent much time researching recomendations and finally discovered this DDK is all you need to roost proper. No ($$) 7.0 slides, okay! Your stock needle will work with the 42 pilot for now, even at sea level. BTW, run 40:1 mix ratio, less black drool.
DDK's improve up to 1/4 throttle performance(leaner, better roll-on power) and I didn't have to go up 2 steps on the main as was suggested?
For a confounding performance boost, chose the FMF switchable CDI(on sale, $100US reg. $400) . "Torque" setting, stronger yet smooth for slick conditions or "Boost" setting for ripping MX power. Simple and cheap, that's it. No pipe can do this and the DDK($5US) is the best in torque improvements.
This ignition will give hyper response, pull hard and long. Equal to 250 acceleration and top-end speed. I was told that I was 10 times faster on the trail after installing this part.
Good luck
