How should I break in?

[Stock 400 rider]

Not sure if I`m posting this in the right place but I just got a YFZ450.

My question is: how should I break in, I mean should I do it like the manual says or riding it hard as some people claim that is turns out to have more power doing this way.

Thanks in advance

i let my blaster idle till it warmed up, then rode it hard. not sure if its right, but it seems to be considerably faster than other stock blasters.

Heat cycles are the key. Let it warm up ride it then let it completly cool down. Do this 5-10 times. Always keep steady compression on the cylinders (i.e. don't lug it in too high of a gear.) Don't be scared to open it up just don't hold it there. Have fun. :D

i have heard pretty of things but i have broken several in lately and what you wanna go is ride it for about 30 min do not babby it but dont wind it out getting it wound out here and there is on but after that 30 min you wanna let it kool down then you ride it again..... repeat this until you have rode 2 gas tanks through it and the you can get it what shes got

I know on my Predator when i first got it the break in period was 1 hour of riding or 1 tank of gas. I don't know just a thought. Hope it helps.
