RPM recomendations will vary, I broke it in like I would drive it, but carefully. You can safely take it to 5,000 - 6,000 but only for short times then back it off.
Vary the RPMs as much as possible averaging at 4,000, don't poke around @ 30 all day.
Change the oil & filter between 50 and 100 miles (You will see shavings), It is said by other mechanics that 50%-70% of the inital breakin happens @ 20-50 miles. Then change it again @ 800 miles (you will still see some shavings but not as bad). 3,000 mile interval after that.
The bike will be a lot happier. It's not really fully broke in till you have about 3,000 miles on it.
Gradually increase the higher RPM time for about 500-800 miles I was running 2 up @ 70 for a mile or 2 @ 300 miles, No problem, @ 3,000 miles it was still getting stronger.
I apply this method to ALL my equipment with excellent results
