All the oil leaked out the left side... was created by rpaldrich
1971 AT1 --- I'm well on my way to getting this bike trail-worthy (thanks to your help). BUT, when I filled the transmission case with oil, all of it slowly leaked out through what looks like the chain sproket area. I'll get a pic up here soon, but what advice do you have on what to do? On the right side, I had taken apart the clutch and reassembled with a new kickstarter seal, and then put a new gasket on the right transmission case with Yamalube's appropriate sealant, but I have not touched anything deeper in the transmission ().
I'm pretty sure the oil is coming from the sprocket area. How hard is it to change the seal there?
Thanks!
My ongoing to-do list:
--unfreeze clutch plates (Even with clutch pulled in I cannot disengage motor from tranny) DONE
--replace clutch adjustment screw (frozen. Perhaps I'm not getting enough clutch engagement which is causing the above) DONE
--fill gas tank with vinegar and flush out all the surface rust in interior DONE, but rust came back
--fix kick-starter. I think it is missing a shim, but it is getting stuck at the bottom of the stroke. Not a big deal, but annoying DONE
--do something with the front forks cause they are way too spongy.
--replace kick starter gear cause the teeth are somewhat chewed up NOT DONE -- Replacement I got was the wrong size, but the shim fixed it.
--replace/refit original tool kit
--get safety gear for riding
--Title/Register and ride

If it wasn't leaking before working on the clutch are you sure it isn't migrating over from the clutch side? I'd clean everything up, dust it with baby powder, put oil in, then see where it's originating.

On your gas tank clean it again to remove the rust and dry it out go to a auto paint store and get some metal etch small can then put it in your tank slosh it around for a couple of minutes then pour it out let it dry then put about 12 oz premix gas and oil shake it then it shouldn’t rust anymore that’s what I do and have had good luck with no rust

Yes that is a good idea I'll check that. Pretty sure it was empty when I got it, bike had been sitting for a dozen years.

Pretty hard for much oil to leak from sprocket seal while parked. And for "all" to leak out when parked, leak would have to be much lower like shift shaft seal.
When replacing shift shaft seal it's really easy to disconnect the shift linkage under the clutch cover if the shaft moves in a little bit so you might be removing the clutch cover again if it is the shift shaft seal.
