Im typically not another one of these guys KXF bashing, but today I am. I loved my 250f, untill the weekend, like everyone else praised them told everyone to buy one, not any more. 30hours old, pulled the rocker cover off and the valve clearances were sweet, went for a ride and 15mins later. well you can see the pictures as proof. Check out my garage, if you still do no believe me ill take another photo of the motor in my bike. Sure go ahead buy a KXF itll cost you serious $$$$. Oh yea Kawasaki just said "...its a race motor, it happens..."
