I have an 2001 YZ426f and live in San Diego. I ride mostly in the surrounding desert so nothing ever above 2000 ft elevation. I am taking a hunting trip in a few weeks in the mountains of Idaho and am planning on using my dirt bike for transportation. Do I have to change the jetting for it to run up there? Will be between 7500-10000 ft. I don't mind if it runs a little funny as long as it runs. I just need it to get around up there. Thanks in advance.
