Yes, older Djebel200 models had the same Cam;(and Power=18hp) ,that DR200, However, newer Djebel models declare 20hp(2002); I cant say for sure , first hand, as I havent seen it in person,Is it True?; if Yes, ¿where gets 2hp more?!; my guess is that some of these new features is to be blamed:
1/New Oil cooler may help.(to stabilize-Not increase- power)
2/New bigger(in diameter) exhaust+header.
3/Carburetor : here is the MAIN difference : while our qingqi 200(or whatever make you had) has "only 28mm/16hp". Suzuki has allways mounted 31mm/33mm!. You can even fit a Keihin FCR35mm. That will ,probably,make a world of a difference at high RPM, but costs a fortune($700). This alone doesnt make much sense ; unless you remove first the standard CDI, for another "Unlimited"(see forchetto posts); to get its full potential.

There are cheaper ways to "release" the easy/Cheap HP out of your XP200.
-remove EGR valve (from 2007 on)
-Open -Dont remove-, 2x 25mm holes on top of your airbox.
-Install bigger =Idle+Main Jets.(Kientech.com)
-LT250S Cam.
That only, once installed, gives you 19hp; 130km/h with a 16t front sprocket.
If you add a DR200 33mm Carb youll hit 21/22hp.
