106 seems slow for a KR. Ask where is the heat being generated that is closest to oil? If everything else is right it has to be the bottom of the pistons. It seems to me that proper cooling is a system. Baffling, fuel, ignition timing. You mention oil temp, what about cylinder head temps? It is helpful to have all parts of the puzzle.
