Welcome to the site :cool:
Be sure and go to your User CP and update information relating to your location, type of riding, etc. After that grab a spot on the couch and tell us a bit about yourself. How long you have been riding, what kind of riding you prefer, where you are located, etc.
I'll pass a note on to the Godfather of the CR and see if he can help you. You can also click on Service Honda in the list to the left of the forum. That will lead you to his shop.
Kav gave you some great links to start with. You can also check out the
CR / KX / RM / YZ (2-Stroke) Discussion forum.
Again, welcome to the site, and shout if you have any questions!
