Sounds like chain slack issue. 50mm is about right. i have also found if the chain hasn't been lubed in a while it doesn't help. I have owned 4 different gen 1 fazers and they all had different feel to there gearboxes and subsequently felt better/worse.. T.B.H the gearbox may be strong but it is a shit change compared to a suzuki or aprilia.
If it's broken, it's not fixed.
