Max motoring does not mean, motor for '5 minutes' or to starter time limits, it means motoring to maximum N3 / N2 rotation speed prior to introducing fuel.On the 75/67 this is not even remotely close to the starter limit time.In 11 years on the type I have not seen a starter or engine problem.
I am not familiar with light business jet / turboprop type engines but imagine that they would probably start cooler using the same procedure.
