BEST JETTING FOR 5,000 to 8,000 FEET?

Anyone know the best jetting for 5k to 7K feet on the 650R. Have stock carb, power up kit and PowerCore 4 SQ SA.

Please email response:


When I was at the Colorado 500 last year, I ran a 168 main and 45 pilot. We were 8 to 14,000 ft. Could have leaned it but it was allright. Here in WA, 5-8 thou I would run a 170 main and 45 pilot, possibly a 48. Best thing to do is take a few extras, and experiment.
