The #1 exhaust needs nothing. All of the others need a shim one size smaller (-.05mm) than what they currently have in them. As stated, you can't know what size might currently be in place until you see them, and they are all apt to be different. Usually, you can "shuffle" them around and adjust 4 valves by using two old shims and two new ones.
Service shims are sold by Yamaha in increments of .05mm (.002"), and are marked by their actual size (180, 185, etc. 185 + 1.85mm) If the engine has never had a valve adjustment (don't think for a minute that's not possible), or has been adjusted by a shop tech who used used shims from his collection, you may find shims marked in odd sizes like 178 or 182. These are original factory shims available in .01mm increments, provided only to the original assemblers.
Remember that the whole specified range is only .002" wide, so don't obsess about where within the range your clearances end up as long as they are within the range.
