If it's a brand new one, I suggest replacing it ASAP - I used Mobil Synthetic Motorcycle oil 10w-40 I live in Michigan and then I replaced it again at about 600 miles. You should be able to see what color it is through the window on the right hand side. Above that, you should see a screw cap. Probably has a raised "Flat" to help you unscrew it. Warm the engine before draining. It will help drain.
Underneath the engine there should be a large bolt, right in the middle. Put something under it before you unscrew it though. Drain out the old crap, refit the bolt and fill with the bike upright. Check level in the window. Note how much you used, then you will know better for the next time.

Be better if you put some pictures of your bike/engine - especially the right side, and maybe underneath, There also might be an oil screen on the left. pics..pics..pics
