Humm, when I think of "Replaced Valve stems", I think of tire Schrader valve assemblies.
Most valve Guide Seals that I have dealt with on Kawasaki M/C & ATV's have had quite a 'Grip' on the valve guide. Hard to remove & one could possibly damage the bore for the shim bucket on a KLR if one was not extremely careful.
Maybe you did not fully seat all of your new valve guide seals completely onto the guides?
