There seems to be a plug missing on the upper right side of the head right next to where the header comes out of the motor. There seems to be a little pressure coming from the hole and it is spitting a litle bit of oil, enough to smoke on the header. I have no idea what that piece is or where to get one. I think maybe it was a rubber plug. New to the forum; please help!

Welcome to TT!

Your decompression plug is gone. Yamaha used a cheap rubber plug thats known for blowing out.

You need a billet plug like this: http://cgi.ebay.com/...sQ5fAccessories
