I have here for sale the fastest YZ-250 you will find. It will smoke any 450 on the track. I have had it out to the dirt drags and it toasted all the other bikes 450's, 500's, everything. I have replaced the bottom end and had the top end bored to 300cc. I just put in new powerbands (blue ones for maximum power). It has a fuel injector from a KX-500 because the stock one could not put in enough fuel to make her run to her full potential. I have strategically drilled holes in the reeds to allow maximum fuel and air entry into the combustion cylinder and increase fuel atomization. The exhaust is custom made by my friend because no one makes a big bore pipe for this thing. I removed the head gasket and used RTV to lower it and create more compression. It has stage 3 cams installed. It runs only on VP oxygenated race fuel which you can buy at iron pony. All internal parts have been coated by microblue so there is almost no friction inside, I mix the the oil at 90 to 1 ratio due to this coating. It really saves you money on premix. As you can see from the picture the bike has custom one of a kind graphics and is extremely clean. You can also see the tires are good because they still have knobbies on them. I will warn you, this bike is not for a beginner. This machine is full on pro race bike material. I have the largest front sprocket and the smallest rear sprocket you can by on it for top speed! I removed first and second gear to save weight. It is now a 3 speed transmission and it is all you need. 1st and 2nd gear made the thing impossible to ride, it wanted to wheelie and come over backwards on me with even the slightest throttle. I did not touch the suspension, the engine provides so much power you can use throttle control to make the suspension act the way you want it to in chop and small stuff. It never bottoms out on big landings, I have flat landed this thing from at least 30 feet high and never bottomed out. It is just too much bike for me now, I am getting on in age and want to get something a bit more mellow. I am asking $1200. Thanks for looking
