pilots and screws stay the same, although you may want to adjust the screws a bit for temperature.

yamaha recommended a nozzle and main nozzle change for high altitude as well as a gear drop.

for the nozzles use the 0.9 pt # 8OL-14489-00-00
for the main nozzle use the 8Y2-2A pt #8Y2-14941-2A-00
gearing at 16/33 or 16/35

make sure the air bleed hole faces the rear and its centered when replacing the nozzle.
