450 jetting for 7000+ feet?

5 posts in this topic

We are gettin' ready to head up to Colorado for a few weeks of single track trails with the majority of the stuff being around 7000 feet with a few runs up to 10000 feet. Does anybody have any jetting recommendations for that kind of altitude running a stock 03 YZ450?

Thanks in advance,

Pat

All I have is for the 426 I would be happy to send it to you as a point of reference.

Ditto what Cheeze said.

But, based on my experience w/ this w/ a few other bikes, it if were me I'd go ahead and go 2 sizes leaner on pilot, main, and clip position right off the bat. That will be worlds better than stock, that is for certain.

Hope this helps.

Thanks fellas. I saw the jetting link but didn't bother going through it as I was looking for some unusual jetting specs, little did I know that you had the info I needed 3 posts from the top. I'm totally stoked about the trip, have your ridden around Taylor Park Resevoir north of Gunnison much?
