Main jets?

Does anyone know what size main jets a stock 99 Indy 500 takes at 8000 feet elevation?
 
Is it an RMK or not? RMKs had differnt needles so the jetting is different for them vrs the flat land sleds. The RMK came stock setup for 6-9k and 10-40 degrees F. It also had the ACCS on it. That was 260 with the needle in #3. You shouldn't have to change it unless you ride in warmer temps, the ACCS should compensate for the altitude.

If it isn't an RMK, then you are going to have to tweak a bit. Jetting chart says 250 mains with the clip raised 1 spot.
