Just something short since I am thinking of it.
Whether you ride a street bike, dual sport or dirt bike remember that after each ride go over that bike. What I have done for years which my Dad made us do. After each ride wash the bike and go over it as you clean it. This is a good time to make sure everything is in it place. After you are done wahing and drying it, lube the chain, clean the air filter, etc. I would especially do this if you have been out pounding the trails or the motocross track. Better to be safe than sorry. If you are racing there is nothing worse than getting out there and have something go wrong because you didn't go over the motorcycle. Save yourself from having a DNF after your name.
