Hi to every one i am in a dilemma,  i have an FZS 600 engine to rebuild no real problem in the rebuild but i am now at the head stage of the re build, i have nearly all the shims but am on missing one, the problem i have is the shims were all mixed up and dont know which one goes where the dilemma  is how the hell do i know or work out what shim goes where, any help would be greatly appreciated  
Thanks
