i waited about 250 miles to have the dealer put on my stage 4 kit, so i had a margin just in case the bike did something wierd and we did not know what might have caused it. the dealer considered the bike fully under warranty with the stage 4 kit, since i spend allot of my day trouble shooting i just like to start with a stable system before i change anything. then a few hundred miles later the dealer installed my 280 rear, then the f200 ront end a few thousand miles more, because it took that long to find all the parts (note, some custom parts makers are lying sacks of $hit).
as for the breakin thing, that is bull, but from a "what might be the problem side, not a bad idea to know everything is good before you change something.
my dealers shop manger (dave at michaels power sports in reno) has taken great care of me every step of the way. they have put on every part that i did not have time to put on and taken alot of pride in their work. i only mention that because if you have a good shop manager that takes care of you, that is a good thing. they are good friends to have. i do try to live with his recommendations, like once he reminded me to refill the nitrous tank when i brought the bike in so he could "check somethings out" if they buy in to what you are doing, life will be better when (if) things go wrong
btw, it would have taken less time to do the few hundred miles then to write this answer, so ride this weekend, put on the miles, and then put on the fat a$$ next weekend.
