Just purchased a 2009 WR450F. Never had an F model before, so I dont really know that much about them. I will be doing lots of searches here on this section of the forum. All the rest of my time had been spent over on Yamaha Dual Sport. So, anything I need to know about this bike? Recalls, immediate fixes, concerns etc etc. I will be greasing the stearing head bearings and swing arm to start. Thanks.
