Fellow HBRR member, and general all around nice guy, TN Posted certain technical information introduced at the dealer meeting concerning yet another new oil pump for all M8 motors that was a rolling change made to all 2020 and any 2019 models manufactured after May 22 2019. They changed the distribution within the pump housing to increase scavenging from the crankcase 44 percent, and reducing scavenging from the cam chest area.

Maybe this will help fix the sumping issue.

Guess they looked at what the S&S pump was doing, as it has much increased case scavenging according to their web site.  I do not remember exact numbers but it was at least 33% more.

Certainly hope so, but I think we all know the real root cause isn't the oil pump.  Perhaps a higher volume (scavenge side) pump can overcome the real issue well enough to "fix" most bikes, but I'm guessing there will still be failures.  Kind of like when you use a straw in a soft drink bottle and the level of the liquid drops, exposing the straw to air, no matter how hard you suck on that straw you aren't going to get the normal amount of fluid.  If the oil in the crankcase isn't flowing by gravity to the pickup area for the pump fast enough, eventually even the best pump is going to suck air.  A better pump may help the system recover faster, but I doubt it will cure the real problem.  I guess we will see.

I sure hope no one that buys a 2020 sumps. If we see new guys posting about 2020s sumping in Oct/Nov this year, I can’t imagine how this market will react.

I see Feuling have released a vented dipstick in an attempt to prevent sumping on M8s. Any thoughts anyone?

Sold by many companies, they won't affect sumping, and they won't add performance.  In other words, a so-called solution in search of a problem, designed to relieve folks of their money by cashing in on worries about M8 sumping.  I recommend you keep your money in your pocket.

What Jerry said. Completely irrelevant to addressing sumping. Unless the oil dipstick somehow vented the crankcase it'll make no difference to the issue of sumping. Now the latest 2020 oil pump "might" be a real solution if the scavenging "strength" is enough to overcome any vacuum in the crankcase.

I just bought a new 2019 CVO Street Glide and when I pick it up on Friday, will have the dealer installed Stage III with the S&S Blue Cam Plate and Oil pump. There are a lot of differences between this pump and the stock pump. This is my first HD so I hope I don't have issues as I'm riding my 2018 BMW K1600b to the dealer and trading that.

Wish me luck!

I assume you don't care about the warranty, since you're planning to use aftermarket parts.  Good luck, and I hope it works out for you.
