My engine seams to be leaking oil from under the exhaust manifold on one of the cylinders, any ideas on why that is and what i should do?

You probably just need new Exhaust gaskets. They go pretty often.
how much are those and are they easy to change

Pretty cheap, like 10 Bux at your Yamaha Dealer. Very easy fix, take your Exhaust off, take the 4 bolts Holding the Exhaust to your Engine, and replace the gaskets, I like to also use some Gasket Seal with it, and then put the bolts back on. Just a Tip, I'd use some threadlocker on the bolts when you put it back, I didn't last year, and one of the bolts came off on the trail.
ok sounds good thanks
I just took of my exhaust pipe and some oil poured out, do you still think that is gasket?

You are probably running too rich if its "pouring out" a little is normal, if you fogged the engine then that is very likely the culprit or if you have been running it with it warmer out it will run richer causing there to be oil in the exhaust.
If however this is during normal 20* temps or so then you may have a stuck choke, or just to rich a setting. Check the plugs if that is the case.
