Another Question. When I bought my 400EX it came with a Power Core IV pipe. Im not sure if it has been re-jetted or if you even need to. I ride in 3000 to 5000 feet in elevation with usually 70-80 degree temp in the summer, colder in the winter. So if anyone would have any jetting advise I would greatly appreciate it.
