Rm-z 450 leaking oil out cylinder head

I was wondering if anyone knew if the cylinder head of a rm-z 450 is supposed to rock or wobble when on a flat surface? My bikes leaking oil out of the cylinder head
 
Mitch, if you don't have a SHOP MANUAL you may be able to go to bikebandit.com and pull up the parts diagram showing the head. You can see what parts may be involved. Since you sound inexperienced here, I will warn you not to simply tighten the heck out of everything until you find out if that is all it needs. (Because that can end up costing the "heck" out of you.)

Sometimes one can find the problem by assembling parts incorrectly.
