Edumacated opinionzes please. This is a bit of a dead horse, but hey we have more members now and some of them might be smart.
What do you all think of this break-in approach:keep your RPM’s below "half" of whatever your red line RPM is for the first 500 km. It is also important to use "no load" on the throttle - increasing speed and RPMs smoothly and gently, and not accelerating hard. He also told me that for the first 100 km, it is permissible to take first gear up to red line under NO LOAD - VERY GENTLE AND SLOW ACCELLERATION. This is actually really good for the engine, as it helps seat the rings. During 100-200 km, it is okay to take second gear up to red line under NO LOAD. 200-300 km, third gear up to red line. Etc., etc. After 500 km the bike should be broken in and ready to race. Keep in mind that the people who do this use motorcycles for a different purpose than you probably do.
Leaving it idling is NOT a good method for break in. There needs to be SOME load on the engine and there needs to be a variety of RPMs.
