The only way to find out if the jetting is going to work, is to just ride It. If it's not giving you any bogging (Rich) or Poping (Lean) then you should be fine. If you have Poping on decel try turning your Fuel/Air Mixture screw out a 1/4 or a turn, and if you have a really lean or rich mixture ajust the Jet Needle first, (raise (Leaner) or lower (Richer) the clip position to W/E you need to correct your jetting). In my opintion your jetting sounds good, where I live the altitude is 4500ft and about 60 - 80 degrees in the summer, and thats what I would use to start jetting my bike, then go from there.
