I know this will start numerous flames but I always break my engines in the same way. My last GSXR600 AMA bike made 117bhp and my current R1 makes 165bhp. The break in period is to let the rings bed and take the high spots from the crankshaft bearings. Here's how I did it. The bike was warmed in the garage before riding. I then did 10 miles at 6000 rpm max. Engine then was cooled. Next 10 miles was at 7000 rpm max. Engine cooled again. After that I let the engine rev steadily higher and longer. Simple rule - if the engine wants to rev let it, if it feels tight don't force it. By 100 miles the engine was being revved as high as I wanted - bear in mind that you can't really rev a motor too hard on the street anyway. Bike would now be ready to oil change and dyno. At the first oil change I will use Motul synthetic as I always do as I believe the rings will have seated on the bore. That's how I always break in my race and street bikes.
no flame here, i was just curious,i have never heard of that way of breaking in, but if it works, go for it. as for the synthetic, my car came from the factory, and at 600 miles, my bike got the synthetic treatment, thats why i dont understand why someone would say it is too early for it?
