Is that 2500 rpm in 4th gear at 60 mph? Also, what tach do you have? I would love to add one but leery about certain aftermarket stuff.Save that 5th gear for out on the Interstate riding. I have a tach, and @ 60 actual, I'm maybe doing 2500 rpm. @70, I'm running 3K. My actual speed is within 1 to 2 mph of what the speedo shows, thanks to the darkside I ride on the rear.
