I have been reading the posts about riding moab and have never been there. A lot of people in my town ride mtn bikes there, but I want to bring my WR450 there and fly by them like a bat outta hell! I only live 4-5 hours away so it should be a no-brainer. Would I need to change my jetting? I live and ride at 8000+ feet. Does anyone have any good advise on jetting for a 03' wr450 riding in Moab? I don't have the JD Jetting kit. I run a stock needle and am getting a PMB silencer insert in a day or two to complete my setup.
