I RIDE PRETTY CLOSE TO SEA LEVEL IN SO. CAL. I'VE BEEN RIDING MY 426 SINCE LAST NOV. THE BIKE HAS BEEN BURPING ON ACCELERATION AND DECELERATION AND THE PLUG IS ULTRA-WHITE [NO GOOD] SO I CHANGED THE 162 MAIN TO 175 AND THE 42 PILOT TO 45 AS RECOMMENDED BY FMF AND IT SEEMS TO RUN BETTER. I JUST RODE IT AROUND THE BLOCK. I'LL BE ABLE TO GIVE IT A FULL RACE TEST THIS WEEKEND. HAS ANYBODY ELSE HAD THIS EXPERIANCE?
