I finally found a few minutes to move the R65LS around the garage this afternoon. It would appear I discovered another issue for my restoration program. A very visible lubricant leak was observed and appeared to be coming from the right side of the rear drive. Lubricant was running onto the tire and was obviously not coming from the drain plug.
Could this be an explanation for the rear brake appearing to be rather useless at the end of the riding season?
Where do I start with the trouble-shooting process? I assume that the culprit is likely a seal. Is this something that I have a chance to repair?
