It would help if you put up a link to Durwood's report so all of us can reference the same info.
I understand you were just repeating what Durwood said, but now you are (1) comparing a lawnmower one quart too full to an M8 or TC running at the designed oil level; (2) comparing the TC breather/oil usage problem to the M8 sumping. Both of those statements are comparing apples to kangaroos.
Dude, I'm not comparing the M8 to lawnmower engine, just making a statement, I can't help you do not have the capacity to see what I was trying to say. Look it up on the HTT site.
So I copied this from that site.
So your running basically the same amount in your M8 as you did in a Twin Cam now, correct ?

I started this thread last September when I thought the seal was the solution. I just pulled the crank position sensor on my 124” build and got about 7oz out. All of the prior checks on my previous 117” with the Harley cover with the seal resulted in 1 oz or less. I’m not seeing full blown sumping issues but 7oz of oil sloshing around in the lower end can’t be helping performance! I wonder if anyone with the Fueling pump has checked after prolonged high rpm runs? I also have installed a vent on the oil fill....
Big T you might try running your oil level a quart low.
That's what I did after mine sumped 2 quarts and now I am getting 4.5 oz from the sump plug, not the CPS.
Besides the piston oilers being loose and leaking on some bikes, I honestly believe that Harley's suggested oil level is too much and the main cause of the sumping M8's. JMO

Yes, and I can't make it sump.
