“I would love to see a slightly tighter 3-4, but we contended last year, and I'm willing to wind it tighter this year in the lower gears to put it where it needs to be to pull the top.
It will wind to 9k, and if it's will do so strongly in 3rd, I think we'll be golden.”
Chris,
Estimating the power curve from the photo in the diary, and plugging in various factors, we get the following (attached) graph of power as a function of speed. (Worksheet was originally made for a 5-speed, so 4th and 5th are plotted on top of each other) It would appear that the 3-4 shift is probably alright, and per your statement that the power below 6900 rpm was fairly strong, that shift point probably doesn’t need to be much higher than 8200-8300. If we had results for below 6900, it could be added to confirm that. That would also shed light on the 2-3 shift for which there is a larger gap in the data. You might want to wind it tighter here, but probably doesn’t need to be much more than 8500. Again, results below 6900 would be good to have. Also, an actual loaded rolling radius or rollout measurement would be more accurate than the estimate used based on the 22” tire.
