Hey! First time poster here on HondaTwins.
I just bought my first bike on Craigslist the other night - an '81 CM400e. Seemed to be running fine, the PO gave me all of the repair logs up until this point (replaced sparkplugs, Flushed / synced carbs, updated electronics etc.) He says he rode it this past summer and it was running without issue.
Today I turned it on and idled it then revved it to show off the bike to a buddy. Right away, I noticed the bike was leaking oil and there was black sludge/oil sputtering out of the exhaust. (pictured below) Texted the seller pics and he straight away sent them to his mechanic for a diagnostic. In the meantime, I'm wondering if anyone could point me towards a starting point to addressing the issue and understand whats going on. I'm completely new to this and am excited to get my hands greasy!
