Yes I meant convex as in thicker in the middle as it would apply to a KLR shim although the reference was really to automotive lifters. I'm 99.99999999% positive the KLR shims are ground flat just too lazy to go check. I get your point about a shim might have gone 'concave'. That is possible. One other possibility is if the shim was new with a rust inhibitor it would have fit tighter until the coating dissolved. And yes I have also seen shims that are slightly off from as marked. Walt
