i owned a 98 fIII 700 , so i voted for the mach z,BUT i would love to see that 809 in the REV. by the looks of the REV ,it more in likely will not fit. if it were a choice between the 800 or 600ho twins, my conclusion is the 600ho because the 800 has been out for a couple years now and they are still having problems getting them dialed in. thats only my opinion.
