Five plate six spring clutch. Set up the plate run-out with a DTI and adjusted pushrod screw adjustment as the book says. Clutch plates unworn and springs standard length.
 Now it goes into gear nicely, the centre comes to a gentle halt with the engine running and clutch pulled in, but it's still a sod to get into neutral when stationary.
Any tips?

I think it is a perennial problem.
Sounds like you have the clutch set up nicely.
Presume it wants either 1st or 2nd and slips through neutral both ways?
I believe that increasing the preload on the completed detent spring makes it more positive but also means that 1st to second and 2nd to first will need to be a more positive foot movement to pass the neutral notch.
I have found genuine Surflex plates better than cork and I've been using modern Castrol Power1 10/30 (suitable for bikes with integral enigine/gearbox and clutch and it seems pretty good on first set up. 
My other modded bike with NEB clutch was initially perfect but now drags a smidge (Triumph like clunk on selecting first from cold, and slightly fiddly finding neutral when hot).  I've meant to tweak my detent spring but been too idle, also have got into habit of selecting neutral just before coming to stand still!

Thanks for the in-depth reply.
Yes, the same old 2nd 1st 2nd 1st missing N every time.
I agree that clicking into N before stopping is the way to go, but sometimes stops are more hurried than others. ;)

I don't really see what more fettling or adjusting I can do, although I'll look into the detent spring mod. If I find the bike to be unpleasant (due to this clutch action) I shall go down the Triumph 4-spring option as a mate has a unit he isn't using.
Would this be a straight replacement? I can't seem to find much info in the previous posts.

If using Truimph style clutch on an early single make sure you have the right clutch centre.
