Bought a 2019 Road King in January. At about 500 miles I felt what seemed like sumping (sudden loss of power), but it cleared up after it sat for a little while.
Today, at about 1100 miles I felt the sumping again, but this time it started making engine noises, but would still start up and was drivable. Since I was only a couple miles from a Harley Dealer I nursed it in there, where it currently sets.
I should know something tomorrow, but clearly the 2019's still have the sumping issue. The bike is bone stock and is due for a 124 upgrade at Fuelmoto in late May -- now I'm not so sure.

 

What is the build date of your bike?

 

Don't know - can I determine that from the VIN? Bikes in the shop and not accessible -- was bought mid-Jan.

 

So the bike losses power it's automatically sumping.... Why not wait for the service report before doing the conclusion high jump ?

 

You can narrow it down to the month by checking the frame, there's a sticker on it showing month/year of manufacture. I asked about build date because sometime after the start of MY '19 production H-D started installing an oil pump with a revised backplate/seal that was intended to stop sumping.

If your bike was an early build it didn't get this update installed at the factory.

 

The updated parts won't keep them all from sumping.

My 2019 Limited sumped at 7,400 miles. Repaired per SB M1450. Sumped again within 30 miles.

Dealer had the bike 5 weeks. Harley eventually got involved. Don't know if it got fixed the third time or not. I got rid of the POS!

Nobody gave a rip that it was down in prime riding weather. Customer service from the MOCO and dealer sucked! The MOCO never contacted me after contacting them 4 times for the sumping issue.

So your bike or your mates bike sumped ? As you've stated else where "his" bike did and now it's "your" bike, I believe it's no bike .

Peace.

 

The dealer said one of the first things they'll check is whether its got the reviised backplate/seal. As well as calling the MOCO. Hopefully I'll hear something later today.

This also seems to be one of the more competent dealers around here -- they mentioned that the Fat Clutch Rod appeared to solve the Fluid transfer problems (the other design problem with the M8) and had installed several on customers bikes. Not something I expected to hear from a Dealer.

 

Looking forward to hearing the answer to this one. Subscribed. Thanks for keeping us updated.

 

You caught me Newbie or should I refer to you as Dick Tracy!

It was my bike and my experience. Didn't want to post on my sumping issue before the fiasco was over, but I did. It was finally over and settled Saturday. My 2019 114" Limited is gone!
