Selector rod, sticking in neutral and jumping out of gear back to neutral

[Fazerider]

Yes I've read through that many times already which is what leads me to think trying the selector forks and drum but saying that it didn't fix yours did it?

Mine isn't quite perfect, very occasionally if I get the revs wrong whilst flicking to change up I'll get a false neutral... second and sixth are the ones that show the problem. I guess there's some damage to the dogs themselves, but that's more of a job than I fancy tackling. So far as the main difficulty of being unable to get out of neutral goes though, yes, it's fixed it.
