Hi guys new member from NZ. A proud owner of a wine coloured 2019 CVO. 1800 klms, most of them workshop ones and now back in the workshop for second time with loss of power issues. Makes me pretty sad this was to be my forever bike. It appears to me the only straight answers are coming from these types of platforms and on this isuue everyone has an opinion. First up dealer looking after me real well, trust them 100% but not Harley. Obviously there is a problem of sorts with these motors and its so prevalant that Harley would have to be blind to not see it. Can someone tell me why no one who should has stood up and said "yup problem and here is a solutio". I would have thought 150 years of building bikes they would have sorted this out or is the potential for a huge loss so big its just coltaeral damage and this includes some of the dealers or am I over reacting? Be great to hear your feed back. Our laws are on my side at this stage and I can legally claim all of my money back. Should I? And should I just invest in a low klm 2015 CVO sTreetglide.
Appreciate your advice folk thanks.

Unfortunately, M8 sumping and fluid migration from the transmission to primary are the trademark problems with this engine.  Why hasn't HD addressed the issue?  JM2C, the MoCo poorly designed the M8 oiling system and to correct the problem on every bike would be financially crippling.  That's why we saw various "fixes," hoping one of them would be the solution that counters the real problem.  It's much cheaper to address sumping bikes in piecemeal fashion than a total recall.  Not what you wanted to hear, but this is my take...along with many others.

Yea thanks Mark, I kinda figured as much. What I struggle with is though why not all the motors, it seems to pick on one bike and doesnt let go?

What's the build date of the bike. You will find it on the left front down tube as I'm curious about what oil pump and plate are in it.

In 2-3 years I'll be getting my 'for ever retirement' bike.....and do not want to deal with these serious issues either...my '12 has enough issues! I'd take my money back....get the '15 and fix the known issues with known solutions.
I am really starting to doubt that my 'for ever' bike will be a Harley.

Have a 17 Road Glide in the shop with both issues. This is what we did to correct.  Added a Greg Williams shaft along with S&S 80W140 Gear oil for the transfer.  For sumping what we found was rear cylinder was out of round .004".  Bored 114 cylinders to match Mahle 120 flat tops.  The piston jets were somewhat loose and definitely not flat which we resurfaced and used cometic gaskets,  Added a 2020 oil pump along with zero deck height and CR480 Cam.  Bike had 25K miles before failure.  Running VR1 high zinc 20W50 oil.

Thanks guys I will attend to the requests and also supply build date for the bike. Sad.

            I know you've all heard it before, But after hearing about the migration, and sumping problems, and after 3 years they still don't seem to get it right, and then on top of that they don't want to warranty it in some cases, is why when I find a buyer for my 16 CVO Street Glide and 14 Ultra Limited I'm moving on. Paying to much for a bike is one thing, but not having stand behind it is another, and living up north I'm not about have it in the shop most of the riding season.

Sorry to hear about your troubles. Nothing more frustrating than weeks/months at the dealer without certainty the problem is fixed.

Bought my CVO RG this past July, my bike has had both issues!! Hopefully I’m solving the problem as I type..Big bore 128 with head and valve work, SS oil pump and cam plate... Time will tell... I definitely don’t have a warranty to fall back on now, I NEVER trusted them to fix it in the first place... My bike started having both issues with just over 300 miles on it completely stock.... I wish you luck and hopefully they take care of you... I personally would get all my money back and move on if I were in your situation.... Scott

When you say both issues, are you including the transmission oil migration to the primary as the second issue?  If so, your listed mods won't fix that problem.  Installing a vent in the primary will stop the migration.  It should be a warranty repair, Harley has the vent kit available.  If the primary is already opened up for the other work, it would be a great time to also do the vent install to avoid another teardown.

I have a 2017 SGS that started the fluid transfer this year at 6,700 miles. I serviced the bike for winter and noticed the primary was about 10 ounces over full and my tranny was that much down. I contacted my dealer and he set up an appointment for me and they installed the HD vent kit.

Winter is here so I have not had a chance to even drive it since the update. I did not experience any sumping with the motor so I will keep my fingers crossed.

My buddy also has a 2017 SGS and we serviced his bike late this fall too and his checked out ok on both the fluid transferring and sumping.

I'm surprised that a class action suit has not been filed against HD.

I have to agree with your post.
