I'm jetted for around 0-500'. I can ride logging roads that go up to around 5000' with no problems. It is noticeably down on power but is ok for just cruising a road or easy trail. When I go to sand mountain 4000' and drag race up the hill it is also noticeably down on power but still does OK. I would rather be jetted rich at high elev and correct at the bottom of the hill rather than lean at the bottom and good at the top. 9000 ft will be very thin air, it will be quite noticeable. Bring a new change of plugs just in case.

every body will bad mouth the power jets and dial a jets, but give them a try. once you get your adjustment for low and high elevations, find a way to rig a little handle on it with a stop so that while your riding wou can just stick ur hand under there and slap it. I have seen bikes set up for pikes peak style riding with this mod when i was in washington. I tried to take pix of a 310 powervalve 250r motor with a spring loaded setup that I believe was esr built but was immediately shouted at so you gotta use your imagination.

if there is a local gas station near or @ that altitude and you are running pump. go empty, and fill up with that gas. the sg of that fuel should get you running right or at least close. don't forget to switch back when you go back to lower elevations.
