My bike ghost shifts. In researching this, Honda dealers act like they have never heard of such a thing and blame my shifting technique. I've been riding a long time and my shifting technique is fine. I found a former Honda mechanic who was familiar with the problem and he said the best bet is to ride the bike until the transmission fails, then swap out the engine/transmission and keep riding. I will note, however, that my bike is ghost shifting less these days (several rides without it happening at all).
