Leaking air between roller bearing and cam shaft. Replaced crank seal out of curiosity, and still leaking air in the same place. Is it possible the rollar bearing is worn down?
 
You'd have way more than a leaking seal. Do a leak down test with cover on, see if coming out vent tube. Then test with clutch cover off. Spray soapy water at crank. Dollar says you didn't seal seal collar to crank. I also seal keyway out of habit because that's where Banshees leak.

Hopefully you also replaced left side.
What are you using to seal it? Talked to a mechanic, he said I could seal it with yamabond, but also said he wouldn't recommend it? He said the nut should compress the sleeve and bond it without anything.
 
It was not leaking around the seal, just leaking around the collar. I replaced the seal anyway even though it wasn't bad yet. Thanks for the video. There were Mark's on the outside of sleeve from seal, where it was spinning with the crank.
