First, for a little background, I have a 03 RM 250 that I have just broke in. Jetting is stock. I ride right now at 4500 feet, but in a week I'm moving to Avon, CO and the base elevation is 7500 feet.
Now for the questions..................
What jetting would be a good starting point? What are riders at a simular altitude running? Why am I a slow rider......did I say that out loud?
