Thank you to all! Guy rode bike to work and wife texts me that he's happy...no more leaks. Musta been the clogged vent line.

This board is great, appreciate all the help and advise.

 

"So no way to check the level? There is an inspection cover has 2 bolts on the chrome trans case above and left of the diag/pic posted above with the numbers? That where you fill it? Remove the small screws - 2 - and remove the small metal inspection cover?"

That cover is where so you can adjust the chain. Most places say "1/2 of play. You can fill from there, but most recommend through the derby cover so that you can see the level of the oil. But if it's empty 1 quart should do the trick.
