I have a 1990 K1, where I might get an hour into a ride and the tacho drops to zero and I lose power.  Not enough to stop, but enough.  I was researching similar issues and found a Ducati with an intermittent electrical / grounding issue that meant that one cylinder lost power - the one connected to the tacho.  Has anyone seen this problem before?  Is it similar to the Ducati?  I have a manual, but reading the electrical diagrams is beyond me.  Would you know which cylinder to start with?

Got 2 coils, 1 is for cilinder 1 and 4, the other one is for cilinder 2 and 3.
Sounds like a fail on a coil when it gets hot, shit is over when it cools down.

Nice page to watch and about your coils (almost at the bottom of the page)

Also check the earthlines, there is a thick wire on top of the gearbox directly to the battery, a bunch together under the tank, and ofcourse the lines to the coils.
