i agree. when i used to race two stroke karts few years ago we used to run them in as follows

10 min @ 10k
10 min @ 12k
10 min @ 14k
10 min @ 16k
10 min of full throttle anyting up to 18k depending what gearing you ran


i once ran in a stage 2 cvh so gently for 1000miles at 2.5k in my old fiesta and it used so much oil all the time
