Been riding my 69 H1 this season after the resto.
When I’m done at the end of a ride the center exhaust drips a fair amount of black what I can imagine is oil.
Could this be a check valve problem?
Runs well but it’s got me wondering……
Thanks in advance.
Gary.

Where is it leaking? If it is somewhere along the pipe or at a joint, it is simply an exhaust leak. Tighten or plug the leak. There is always some residual oil in the pipes. Since you say it is running nicely, I would lean towards a leak.
But, what do I know ??

The technical term for the black stuff is spooge. On a perfectly sealed exhaust, it helps coat the visor/ windshield of whoever tailgates you.

Spooge good.
Leaks bad.
Of course,my garage floor has lots of that black stuff on it. New rubber flooring cleans up real good...

It leaks from the very end of the pipe. Garage has a 3° slope so it slowly runs out. No leaks along the exhaust pipes.
Better rich than lean!
Thanks all.

How do the plugs look ?
The Ol gal might need a good run to burn the stuff off.

While it's normal to have spooge, be certain your oil lines have properly operating check valves.
An indicator of bad check valves is a bike smoking excessively at startup, worse when you let it sit for a couple of days. Another indication is if there is any air in the oil lines.
The actual test is to hang full oil lines with check valves down overnight to see if they hold oil against gravity.
