Finally got the 426 out to the desert and opened it up big time with the hotcams exhaust cam. With 15/50 gearing and a fresh mix of 50/50 leaded and pump gas I gotta say I was very happy with the power (band). Judging by the traffic on I 15 I'd say it's at the top of the powerband at about 75 mph. More meat just asking for a handfull of throttle. Railing in fresh sand wash like virgin powder rocked. I was able to pull 5th gear wheelies (75mph)that were questionable before. What a great bike. Great mod. I only wish it were 10 lbs. lighter.
