There are a couple school of thought about break in. I’ve always raced mine to bed in the cylinder. The theory is that it’s less likely to buff from being too gentle. You’re bedding in the rings and being too gentle will just buff out the cross hatch. There’s a lot of heat generated so vary the speed and load and don’t run up to peak RPM for a hundred miles or so. Don’t let it sit at idle, not enough oil flow. Use Dino oil. My engines that get bedded in like this has always outperformed others. My stage 2 Harley kept up with bored and stroked motors.
