A pretty common rumor is that 80 percent of the bike's break in happens in the first 30 miles, and 20 percent of the break in happens in the next 1000 miles. For me, I run the bike for the first 30 miles, keeping it in first / second and reving up the engine to about 7000 and then letting the engine slow me down. At 30 miles I take it right back for an oil change to get all the metal shavings and debris out. Those newly assembled engines have a substantial amount of dust, debris, sand, cloth fragments and other pieces of debris in them. Picture how dirty a factory is, now imagine how the inside of the engine looks when you get it. So get that oil circulated for 30 miles, load the enging up to about 8000 and back down.
Also, MAKE SURE YOU WARM UP YOUR ENGING FIRST!!!! LET THAT b&^#@ IDLE FOR AT LEAST 3 MINUTES @ 2000 RPM BEFORE YOU GET ON IT!
At the 30 mile oil change, I'll still put petroleum oil in it, like havoline till 500, then I change again, then change again at 1000.
So for me, this is how I do it-
1) always warm up the engine first
2) Run it to 8000 rpms in first/second gear letting it load and unload
3) change the oil at 30 miles, put petroleum back in it, Still loading the engine up to 8000 RPMS
4) change the oil at 500 miles with petroleum, and get the inspection done, after 500 you're ready to get on it
5) Change at 1000, and it should be ready for sythetic oil
I guess the only true test is to see how the pistons look at 60,000 miles.
