You little %!¤, obviously you haven´t ridden my 160cc 13.5-1 compression,30mm flatside carb, piped, clamp on K&N equipped, vertex ignition lit tt-r sitting in my garage... It will take a modified 85 from 0 to it´s top speed of 67mph where an 85 only does 55 or so. It does use an 85-based swingarm and forks however. Too bad I only have $8,000 or so in it....It´ll beat any kids 85 even with my fat %!¤on it....
