Yes, breather tube is right side of bike (non-drive side). It's definitely tranny, when I say puking I could say pouring, only while leaning on the jiffy stand though. When upright on my lift is barely drips. Oil level and primary level have not changed.

Yep that's the route I'm going. I'm needing information on the OD of the mainshaft, what other seals, gaskets I may run into that I should replace once I have things opened up?

It's a fairly straight forward job swapping out the main shaft seals. Pull the outer primary, clutch (you'll need a clutch puller tool for that), inner primary, drill a hole in the old big seal, screw a dent puller in, pull the seal out, dig out the little inner seal, put it back together.
I had a sprocket nut that had a seal built into it as well for extra measure, back in Shovelhead Daze.

Also upon further VIN decoding I can add some infor to this conversation:
--1HD1BH tells me it a Heavyweight basic Softail manufactured in the US.
--L tells me it's a 1340 EVO
--19 is confusing but the 1 seems to indicate it's a normal introduction year domestic (what's the 9?).
F indicates she's is a 1985
Y = York, PA
Should also note the VIN decoder on this site could not find anything (what's that 9 after the introduction year number?

The 17 digit VIN has a number that was know as a "Check Digit". It's used to validate the VIN some how. Maybe the "9" is the check digit in your YIN?

The problem is the seal is rarely the problem...just replacing the seal is a short term fix. The brass bushing on the mainshaft is almost certainly worn...and if you don't replace it...any "fix" from a new seal will be short lived.
