valve shims for 81gpz1100

anyone have a guestimate on a full set of shims for a gpz1100..

You mean you want to have all the shims you'll need on hand? This would mean you'd need all sizes from 200-300. 300 up are rare so if you stayed with the common sizes you'd need about 20 sizes and to be on the safe side 4 of each and even that may not be enough of a given size. You may need 6 240s for all you know. Say 4 of each size at $11 a shim= $880.00
Otherwise like I say about $11 a shim so if you check clearances and find all 8 messed up, by odds you can swap 2 or 3 around and may need to buy 5 or 6 at $11 each. So depending on the question, there it is
