The best method for this to occur is to run the engine right up to the manufacturers listed "red line", BUT with the LEAST LOAD POSSIBLE (remember load = heat and NEW pistons DO NOT like excessive heat!).
How do you do this? Well, with any vehicle that has a gearbox, it's real easy. When the bike/vehicle is brand new, you begin a series of "low load", HIGH RPM runs (right up to red line), but ONLY in FIRST GEAR. This gives the VERY necessary "high RPM wear-in" for the pistons and max "gas pressure" on the rings to press them into the cylinder wall so they can seat WITHOUT high load/heat.
Not understanding the logic here.....Why would a first-gear blast produce "less load" than, say, a second-gear blast? Just because it's shorter? But the accelerative forces are higher in 1st gear, so you would think that would produce more load.
