Trial of Temptation is Over!

Wow, that takes patience. Mine are always fully broken in at the 400 mile point. I follow the Motoman method and tips I learned with my motocross race bikes. Cool down, torque down, and several oil changes ensure rings seat properly. My first oil change is at 20 miles. Most people that I ride with that follow the manual, I can smell oil from their exhaust when I ride behind them, not the case with my bikes. They are crisp and tight. I will trust the judgement of performance engine builders over product liability lawmakers every time.

Just saying, never an oil burner or a failure here, 30+ bikes and counting. The manufacturers cover themselves on the side of safety, money, and liability. My new mx bikes were always broken in an hour or less. I make 3 oil changes by 600 miles and switch to synthetic after that, not one mechanical failure, transmission, clutch, crank, cam, piston, valve. Nothing, and I run them hard.

I am not saying that I hard break-in the motor, I torque it up and down in each gear for the first 20 miles, let it cool completely and drop the oil. Next time I torque it higher, then 3rd time even higher. By about 250 miles, I am all set.
