I just did my brake in on my 800 xmr today. I rode it like normal, stayed on the dirt roads and did a few quick burst and stayev below 3/4 throttle and varried it often. Once i hit 30 miles it was straight to the mud for some slinging. Only got 4hrs on the bike but it feals stout and i feel confident the motor is gona live a long healthy life. My 800 is an animal im sure that 1k u got is freakin insane.
