I have a 05 YFZ 450 for sale. New mods with less that 2.5 hours on the build which was time spent tuning carb for the new mods. Mods are: Weisco 13:1 High compression piston, Curtis sparks full exhaust with header, Hot Cam valve shims, head rebuilt and tested, Cam mod, Keihin jet kit, additional DynoJet jet kit both with adjustable needles, Violcity intake "airbox completely removed" with new UNI foam filter and pre filter, after market plastics and grapihx, 6pak rack to keep ur man drink cool while ur waiting on ur friends to catch up to you, New helment and goggles, New Magna power Gel battery. 21 Fin inline radiator cooler, Inline coolant temp gauge. engine ice coolant, new oil and filter. runs race gas, has mix of 93 and 112 octane in the tank now and prowedge rear tires, new ramps and tie downs. extra set of shaved blue plastics for racing, only thing it could is a set of nerf bars depending on the type of riding you do. Not reccomended for children, this bike rips and its not completely tuned so when its dialed in its going to be scary fast. gearing is 14/38 also have a new 15T for the front, like i say its all in how you want to ride.
