83 sporty 1000 front sprocket leak
i have a leak that looks like its coming from behind the front sprocket, i took it off and there is a little hole that seems to be for oiling the main shaft out of the tranny. i replaced the seal there and it is still leaking. would replacing the sprocket itself help? what is this little pin hole actually for?

I do not know about the hole. I have had a leak there. The problem was the way the oil seal is enclosed in the oil seal retainer. I had to press the seal right into the retainer rather than allow the installation of the screws to do that. I also included a little Permatex Ultra Blue with the seal. Problem fixed.
If you have removed the sprocket but not the retainer and seal behind it you may not follow what i have said. If so then remove the sprocket again, the retainer is held on by 3 small Phillips head bolts so remove them, and the retainer and the oil seal will come right off - no prying etc necessary.
Ar least gives you a better look at things, perhaps see better where the oil is coming from.

In case you do not know: Oil seals are directional. I do not recall which way it goes. Pay attention to the way it is installed as you remove it. I expect that the side with the spring should face into the holder but you should confirm this.

Hey Blc1313, I know this is an old post Im new to this forum and wanted to ask you if you ever found out where the leak was coming from? I have an 83' as well with the same issue. I can't go for a long ride with out oil getting on my back tire and its been quite frustrating as the bike runs good just feels unsafe with all the oil on my tire.
I soon as I park the bike it leaks almost instantly from under the front sprocket area (no where else surprisingly). I changed the rear main seal, the gasket holding the cover, sprocket and still no luck. Kinda stumped at this point. Any advice would be great!

If it's still leaking from behind the sprocket, did you check the main shaft surface before you fitted the new seal? Also check the gearbox breather isn't blocked.
You can get leaks between the main shaft and the sprocket, as the oil works its way out down the splines. Applying Permatex goo to the sprocket splines before fitting it will usually seal it up, or for a more permanent solution buy one of these, it's a capped sprocket nut that will stop the leak
