Welcome to the site BSM501990 :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. We will do our best to hook you up with some fellow dirt bike enthusiasts.
As far as your questions on the CR500, I would post them in the
CR / KX / RM / YZ (2-Stroke) Discussion forum. There are a number of 500 owners that are members. I am sure they will be glad to help out. Our very own AJ Waggoner with Service Honda is the person responsible for the current versions for sale. He, Eric Gorr and Rich Rohrich have probably forgotten more about the CR 500 than many folks ever knew.
Also, check out the
Damn Yankee Dirt Riders forum for a bunch of friendly folks that surround you that get together and ride at least a couple of times a year.
Again, welcome to the site, and shout if you have any questions!
