This topic has likely been around a time or two. If you want to protect the radiator from stones and debris, you can make a guard from a mesh screen metal waste basket. For the best protection, get the steel mesh. I bought mine at Office Depot (black) oval shape for $19. Cut the screen to fit the area behind the plastic guard. The screen will fit nicely between the plastic guard and the radiator fins. You can attach it in front of the plastic guard as well. I've used this type screen on three FJR's and nary a problem. Much less $$'s than the after mkt. stuff.
