30, 60, 80, are the shift points I also use on my stock America gearing (17/42 teeth), based on rev limiter experience. These points work great for max acceleration. Since I don't have a tach, I just put a blue felt pen mark on the Speedo to know when to shift for max acceleration. I don't know about the shift into 5th, but I suppose that the stated 100mph might be about right.
