Frog my comments were brief leading to misinterpretation. Your comments are not incorrect, the heat I was speaking of is the excessive heat cause by lean running EPA compliant bikes. The new bikes coming from the factory are running excessively lean and are running excessively hot. Especially piston temps.

Just wonder how many police bikes have 100 to 1,000 miles of duty delivering children to school before they can light them up and per-sue some perp?
Do you think that airplanes need 100 to 1000 miles of taxing before they can put it up to 100% to roll down a run way and fly. And they are full of people too!!!
How about rentals cars, taxi cabs, ambulance or police cars?
Lets get real this break in stuff has gotten way out of hand.
Follow Motoman method or risk having an engine that never can break in.

If your not going to go just ride, then "ultrat" says it just as well. At least you will have better piece of mind then taking it out and opening it up.

You're going to hear about heating/cooloing cycles, seating rings, valves, etc., mostly all true from the past, but technology has changed, things are different today, read up, research, do what you feel is best ......

2. You are talking about vehicles that are not personally owned by the operators, thus they don't worry too much about longevity.
Break yours in how you want, and I'll break in mine how I want. I've had many new engines that never use a drop of oil and perform flawlessly for many thousands of miles.
So I agree that this break in stuff has gotten way out of hand. Especially when posting "Follow Motoman method or risk having an engine that never can break in." How about "Follow Motoman method and risk having an engine that won't last very long." Just as much proof either way.

I would think twice before using the procedures outlined on the Mototune site. I've never seen a vehicle manufacturer recommend a break-in procedure like this, and they should know their engines better than the boy-racer who reports his techniques on that site. He says he's broken-in 300 motors like this "with no problems," but has he done objective side-by-side testing based on long-term use? Sure, the motor will perhaps run fine at first, maybe even better since it is breaking-in very fast, but how much abnormal wear has been imposed by the hard break-in that won't show up 'til the engine logs 50k or 100k miles?
I've always more-or-less gone by the book and gone even further by tapering the break-in procedure out for 1000 miles or more, but that's my way and my 2¢. I'm not suggesting that you baby the engine, but just use common sense. Vary the speeds constantly, especially for the first few hundred miles, and taper the maximum RPM and throttle as the miles increase. Resist the temptation to use the cruise control during the break-in period, as you don't want to maintain a constant speed for very long!

Broke my present bike in fairly slow, and it runs great burning practically no oil between changes.

BMW, Porsche and the like all say to drive the engine hard from the start. Most bike manufacturers run every bike on a dyno before shipping. They ride it hard up to red line and shift fast up and down a few times. Race engines are assembled, then put on a bench dyno and run.....hard up to redlines, including F1 engines that rev at 19,000 rpms.
