I've not heard of 6th being a problem, 2nd is the Fazer's usual weak spot.If the selector arm is the cause, then it can be changed without splitting the cases.
Deefer's description is here.
I doubt you can change the cogs themselves the same way. Though, as it's something I may need to do, I'll be happy to be told I'm wrong (by someone who's done it). :lol
