So I purchased an '88 FLHTC (Electra Glide) from a guy last October. He said he had just changed the primary fluid... and in preparing it for winter storage I changed the engine oil and transmission fluid. After several exhilarating rides this spring, I decided to check and change the primary fluid. When I removed the primary chain inspection cover today (with the vehicle upright and level) close to half a quart of fluid drained out of the inspection site! The primary had been over filled. There has been no apparent malfunctions... other than a regular slight primary leak... and I'm wondering if there are any significant ramifications from overfilling the primary. Have you any words of wisdom?
