K-301 Exhaust valve tolerances

[dsarow]

I have a K-301,the exhaust valve when fully open has a slight amount of looseness.You can feel the bit of wiggle.What is acceptable?How should I measure it?If I were to replace it,how would I do it?Any body tell me if this is a common thing?Any help is always appreciated.Thanks.
