I would like to know what settings/adjustments would be recommended to rejet a 2002 Griz 660 back to stock. Currently it is set for 8000-10000 feet which is what I had it set at when I purchased the vehicle since most of my riding is in the Rockies. I will be heading east to the U.P. next week, so I would like to readjust for the lower altitude. Basically what are the recommendations for the following:

1.Main Jet #.
2.Needle Clip position
3.Air Mixture screw adjustment

and any other tips you may have in adjusting the carb. The vehicle is stock, no mods. If anyone has any links for this procedure, that would be great also. Thanks in advance for any replies.
