I need some help here guys. I know your not supposed to ride four strokes in the cold but i had to take it on a little ride when it was about twenty degrees(bad idea). I ended up blowing the cam cover seal. I drained the oil and replaced the seal. After refilling the oil i noticed it was leaking out of the right side of my engine(sitting on the bike its the right side). I noticed it when it started to smoke. I looked down and there was oil spurting out of a hole thats on the side of the head of the engine. I called the local yamaha dealer looking for an answer to what the hole was there for and why it would be leaking oil. They didnt even know there was a hole that was supposed to be there(what help they were). Im confused at to why this it all of a sudden started to leak. Any answers???
