YFZ killer? Isn't your Polaris always broke down? I would not have bought mine if it had a polaris motor in it .
no not always it just went in back to back one time because of my aggresion on the tranny, i actually think that would be a great bike if a yfz had a outlaw/predator engine in it. because i think wat holds the predator back is its weight so if you have the low weight with the power of a polaris i think that would work out well.
