Yeah, not a whole lot different. They are claiming that even though other 1000's have higher HP the CFM 1000 is lighter and therefore giving it a better weight to HP ratio, hence more powerful than some of the other 1000's. I guess I would have liked to see addition of Elka or Fox shocks, slightly chopped cage just something to make it a step up. Can't really see spending the extra $$$ and not really getting anything more than the 800's offer. For all intensive purposes you can probably get the same performance by adding an EJK fuel controller and possibly an exhaust. Even reclock the clutch and and EJK.
Now that Z10........WELL......now THAT's an upgrade!
