Cleaned and reringed the pistons this morning. Removing and refitting new rings does not get any less stressful, but got there in the end, rings right way up, in correct order. Pros make it look effortless, referring to the CB350 race engine video.
Some foreign body has presumably passed through the one cylinder at some point in the engines history, found this mark on one piston top. Obviously not life threatening, as it was filled and hidden by carbon layer, so must have covered a few miles in this state. Not ideal, but it's going back into the engine.
