This needs a new gasket normally, unless there has been some impact damage which has cracked the casing(?) Check where the leak is coming from. If it is further in towards the middle of the bike it could be a crack or a seal between the gearbox and primary chaincase. If it is under the chaincase, you need to remove the footrest/boards and remove the chaincase screws, hitting the outer cover with a rubber mallet to break the seal, and taking off the chaincase cover, clean off the old gasket and applying a new one with some silicone sealer. Make sure you drain the oil from the chaincase or you will have a huge mess!

SOURCE: transmission oil weight recommended for a 1981

All Harley recommends is their Transmission and Primary Lubricant for Sportsters. Now, what weight it is or any additives for the clutch that may be in it is Harley's secret. Also, the "viscosity" rating for gear lube and engine oils are different and I'm not sure how they relate to each other. I've seen advertisements for a 75W90 lubricant for V-Twin transmissions but I'm not sure if that works for the Sportster since the transmission and the primary (which includes the clutch) are lubricated by the same lubricant.

I would think that you would want a lubricant that would have a "high pressure additive" or "anti-shear" additive in it. When you look on the container, you'll see an API code in a round circle. Most of todays oil only carry one rating for use in gasoline engines. Usually it's as "SH" or "SJ". You need an oil that is rated for use in diesel engines to get the additives that I've just talked about. The rating on the container will read something like "SH/CG4", the CG4 rating being for diesel engine use.

Unless you are in an area where the availability of oils is limited, I'd opt for the H-D oil or one of the oils packaged by someone like "Motor Factory" or "Revco". You may find a recommendation by going to some of the oil companies like Shell, Mobil, or Sunoco.

Good Luck

The primary is a 1/8th inch pipe thread, they seem to strip out on a regular basis. Not sure if it's the same on the tranny, you could match them to see if you had to, i reckon. I haven't had to keensert one of those yet.
