I took the oil cap off wen the engine was warm and the rpms did drop. It's hard to say how much because of the revving idle but it was noticeable. I got some carb cleaner and sprayed around a little but wasn't sure of all the place to spray. Is there a thread that shows pictures of the places to check? What are the most common places for a leak? Also I hear a hissing sound coming from the airbox, is is supposed to make a loud hissing sound?
Thanks again to everybody's help. I am a newbie.
