i had to move from 135", pedal to seat height to 137", to be able to get full rotation. did 6 miles the other day with the seat back at 135, some complaints for the first mile , then all went smoothly. so far no flare ups. did a 3 mile walk today as i mix up walks and rides, brilliant spring morning. if all is well tomorrow i will most likely try my old 10 mile route, last done in 2017. not a lot of hp here, not sure about the having to spin a 165 faster. currently running 170mm crank. thanks for the suggestion.
