There has been lots written about checking for excess oil by removing the crank case sensor.  I am new at this and not sure of the procedure or even exactly where the sensor is on my 2019 RG

If anyone has knowledge of this and any photo I would appreciate seeing how to check this and here is why.

.I have been on a trip for two days.  After I ride for about an hour at speeds over 55 and need to accelerate there is no power. It just sputters like it’s not getting fuel and or air.  What’s odd is that if we go through a small town and are running at slow speeds for 5 to 10 minutes it’s fine again for 45 minutes to an hour.

Sounds like a classic case of sumping.  The crank position sensor on the M-8 was moved to the bottom of the cases, it is held in place by one small bolt and has an electrical harness attached.  See if you can find the bulletin on how to check for sumping, I know it's been posted here on the site.  The bulletin number is M1450.

My 19 SG exhibits this behavior intermittently, as well.

I’m having the same issues on my CVO 19 RG only 650 miles on it!!! I’m actually looking forward to having the SS oil pump and cam plate installed when I go with the 128 kit first week of September....

Sure sounds like Sumping to me.  All the right symptoms and goes away when ran easy for a bit.

I wonder if someone could invent an electric oil pump that would attach where the crank sensor goes and pump that oil back to the oil bag.  The hard part would be making it so the crank sensor still did it's job.
Perhaps there is another place to attach it, say an old power steering pump.  Or run it off the water pump shaft.....hmmmm......

Better yet, how about making that dry sump engine a wet sump instead.  Then having all that oil in the sump truly would be normal.

Btw, I love how Harley does everything they can in that service bulletin procedure to minimize the amount of oil in the sump before they have you drop the crank sensor and make the measurement. like let the engine idle to let the pump put more oil back in the pan first.  When you're riding down the road you don't get to let the engine idle for a few minutes every time the sump gets full enough to cause problems.  They know what the problem is, but still persist in leading people on a wild goose chase to try to avoid fixing all but the very worst cases.  Speaking of cases, those new "form fitting" cases are most likely the root cause of the sumping problem.  Read the early press releases and magazine articles about the new M-8 engine if you don't know what I mean about "form fitting" cases.
