Jetting YZ450F

3 posts in this topic

My brother just bought a YZ450 but it seems to be extreamly lean... hard to start when cold, back fire while kicking over. What would be the correct jetting setup for riding in Browns camp altitude? Hope you can help.

Try posting this in the Jetting forum. You'll get a good answer from the man, James Dean. He's ThumperTalk's Jetting Expert.
