Hey folks, Last year I purchased my first dirt bike, a 2005 WR250F. A little old, but low hours and maintained well. I rode it like I stole it this past summer and fall, eventually garaging it for the winter (living in Maine and all...). The top end of the bike has never been done as far as I know. I'm wondering what i should look out for to recognize a failing top end? Thanks for taking the time to read fellas .
