Does anyone have any input on the 800 twins for high marking and powder riding. I was primarily interested in the Rmk 800,144". But lately i've been hearing several rumurs about the power of the AC 800 Mountain cat. The geometry of the RMK seems to be right on the money for mountain riding. Has anyone actually seen the new cat perform, if it does have more power is it setup properly for mountain riding. Do the power valves work as well as they say? This isn't going to be another AC 700 PS is it?
