We can estimate the rpm on the Trinity dyno chart, by calculating the percentage 35 mph is of 75 mph and multiplying that by the rev-limit. It requires a couple of assumptions, but mght be useful.

Assuming the rev-limit is 9000 and the peak speed shown on the chart is the result of the rev-limit, 35 mph would be about 4200 rpm, FWIW.
