TC / MARK , appreciated the feed back. Tomorrow (weather permitting) will
try and get a better reading on the tach. Will also measure tire
circumference. I realize either or both the tach and speedo could be off,
but both bikes aren't pulling past the 133/134 point. Guess a good chance
altitude is taking enough power to drop speed 10 MPH from sea level. Pipes
and modified intake (air boxes or stage 7) are planned for after Laughlin.
Thinking when set up, maybe will pick up a couple extra MPH. THANKS AGAIN
