Dude.... Replace the plug first....
I just went thru the same thing... 4.95 vs a lot more than that.. That's a cheap part at the Moco surprisingly
I replaced the primary gasket twice.. Plug once

Some other thread on here talked about there being a vent for the transmission in that area between the primary and transmission. I had a leak after rides that was due to too much transmission fluid. Just like with the engine oil, "full" on the dipstick may be too much once it is hot and sloshing around.

Another thing I noticed in the pic is that your drive belt is not tracking properly.. It's way to far to he left of the drive pulley.. It should be pretty much centered in the drive pulley... Unless that is that you have a wide tire on there and made adjustments to accept it...

not to insult you, but are you sure it's the primary? sometimes a trans leak can be the problem.

after I replaced the inner primary seal it stopped for a couple months and then started to leak again after a long ride. it is coming out at the rear sprocket between the primary and trans. at this point I have no idea and am about to tear the whole thing apart again.
