Sometimes shifting gear from 5th gear to 4th I find a neutral.This does not happen all the time and only shifting down.My engine is a Bosch bottom end with a Japanese type selector. I suspect its a spring that needs replacing.Anyone have any ideas or experience of this?

4th is the 1/1 coupling : inshaft locks on outshaft. When one of those two has a bit too much play, it doesn't select correct.
There are only three parts involved : one fork, one gear and the outshaft. If these aren't too damaged, You can get away with carefull (and a bit closer) shimming. Good luck.
