How do you start your YZ400..

just put the yz450f exhaust cam and start it like 2 stroke.

its easiest to pull the decomp in and right when your about to kick let it go its all timing and yes when it is cold its best to give it a shot of gas or 2.

Overdue, this is all the info you need right here. I used that same site when I first got my YZ400. I even printed it out in case I was forgetting something. Now I don't even have to think about it.
