You wouldn't have to look. You would know if your sumping when the engine start running bad. The crank case shouldn't have more than a few ounces of oil at any given time. Its a dry sump system. Harley says there shouldn't be more than 6 oz of oil in the crankcase...if it does its sumping and can damage the engine.
I like hearing how many miles people have...the more miles the better I feel about the M8 design.

 

Just hit the thou mark - 1,004 when I rolled her into the dealer for service, but 1,028 now.

 

3250 on my FLSB I picked up NYE. Includes a 1400mi. round trip to AZ bike week a couple weeks ago. This thing is such a pleasure on long smooth asphalt and a ton of fun in the twists.

I've had to add 1/2 quart of oil since 1K service. I keep it half way between add and full.

 

3,000 miles on my 2019 Street Bob that I got on December 2018!

 

1500 miles, bought last weekend in February. Do to medical issues haven't rode or driven anything from April 15th until today.

 

140,000+ miles on my `89 FLSTC...
Bought it new Feb `89.

 

I've put quite a few on my mates little 18 FXBB now and it's a sweet little ride.

Peace.

 

Don't know, can't see odometer thru the condensation that is always present over the bottom quarter of the speedometer. Harley says they will replace my speedometer under warranty if streaks appear with another one that does the same thing.

 

I'll have 1800+ miles by time I get home this afternoon. No condensation problems on mine, clear at all times.

 

46 on mine....it was delivered yesterday.
