well ive heard to baby it, and keep the rpms varying, instead of a constant speed.. then ive heard to run it like a rental... when i got mine, i ran it kindof easy the first hour then it got to go on the creek, and thats the worst place for a bike, because i rode wide open for 11miles, skipping across the crossings, and never got under 45mph... but the grizzlys and rubicons couldnt keep up. and so far ive adjusted the valves and on the next oil change im goin to check them again, but she is still running good with bit over 1200 miles on it...and the last 250ish have been with the 26" MSTs and mud, instead of the stockers and sand/water.. but its your choice on how you want to break it in, i really dont think you can hurt it, just dont check the rev limiter until you have changed the oil the first time... hehehe..
Have fun on your new bike!
