The camplate adjuster is located at the very bottom of the gearbox, its a long threaded piece with a locknut, it houses a plunger and spring, and recommended setting is to have 2 threads visible. Just by coincidence I was experiencing difficulty in engaging 3rd and sometimes 4th gear, needed a second attempt, decided to check camplate adjuster and mine was screwed out by about 12 threads, decided to remove and investigate. It was well gruged up, and the plunger relief hole blocked, cleaned up and refreshed the gear box oil and reset to 2 threads. Not tried it on the road, but appears to be able to select gears on the stand easy enough. When you remove the camplate adjuster be prepared with suitable container to catch the gear box oil, I decided to PTFE tape the thread as there is no sealing washer specified.
