I will be picking up a YZ450F this weekend. My question is what should I be doing to it when I get it home. The bike is an 05 and has literally been ridden 10 times since new. It may have been sitting around for a little while but it doesn't seem to have worried the motor at all as the thing starts 1st or 2nd kick from cold. Should I be looking at changing the oil and coolant? Is checking the valves going to be needed (I know they haven't been checked yet)? Any linkages going to need greasing? I want to make sure that this bike is in top condition before I start putting it through it paces. Any help would be appreciated.
