anyways:

elevation 2200ft all stock.

Call Oregon Trail Yamaha , look them up on the Internet. They are in Baker City, OR. Nick, the mechanic there is pretty good with jetting, he could dial you in for that yz400, I would tell you what I have for mine but it's in the shop and without looking at it, i can't remember.
