Thanks @Plumber32! That's the kind of stuff I was talking about and enjoy reading about. Not that I'd ever tear into my engine like that, but it sure is cool. This has to help someone. There has to be that guy who is tired of getting outran by his buddy and needs a few extra ponies that were left on the table. Also, thanks Honda for making this powerplant so universal. The way they use this engine in everything from a utility rig to a motorcycle really allows us to play around with mods such as this. If they didn't, this stuff wouldn't even be brought up. I like how Honda uses like parts across the board unlike other manufacturers to where if I had a electrical plug go out that I could replace with one off a cbr 1000. Try that on your polaris, can-am, or hell even yamaha.
