the method i have always used is break it in the way your going to ride it. Ther have been plenty of test that have shown a motor will laast long and make more power when broken the way you ride it not take it easy.
Well I mostly ride wheelies on my atv's.. and do stoppies... and hard trail riding... I used to have a 2002 gixxer and i broke it in the same way i would have rode it and i wootered something up on it in the first 500 miles and it never was right.. even after several attempts to fix the problem it still kept doing it.. I can't recall what was wrong with it though ;?
Yep, you'll get many differing responses on this topic. I agree with Motoman too. Not too easy and don't beat the crap out of it. I like heat cycles myself. No full throttle for the first 5 or so hours.
Mine runs like a raped ape now with the intake, exhaust, and PCIII.
