Some fail to break in cylinders and rings because they pussy foot around and end up glazing everything up.

With the strokers, I never set the motor rich, or increase the oil mix when running in. Just run it as is and it will break in.

When you start the motor for the first time immediately start blipping the throttle. Not too high (4 grand's enough) til the engine gets up to about 50 degrees, then blip up to about 7k until the engine's up to around 70 degrees. Then switch off and let cool to ambient temp. That's one heat cycle. Do this three times.

First riding should be up to about 9k for the first ten minutes with maybe half to 3/4 throttle. Not too much load but don't let it chug along at constant throttle. Increase to 10k for ten minutes, then start winding up to WOT and 11k.

Keep clicking gears up and down, and operate the throttle smoothly and you should have it run in in no time.

4 strokes seem to break in quick if you use a low quality oil for the first 100 miles or so. This is what we did on the boiler racers. Then switch to the good stuff. Using the good juice from the off just glazed the bores up no matter how we did it.
