Primary Vent Kit Milwaukee Eight 2019 Road Glide HD M8 fix Oil Transfer Transmission Leak Warranty 

My 19 road king special was done a few weeks ago. Everyone I have seen with this fix never has the transfer issue again. Thanks for showing the work being done. Ride safe!

Thanks for the video and explanation. My 17 RG Spl is in the shop having this and another recall done right now. Harley is always improving on and working to correct any short comings on their platforms.

Great timing, took my 19 Roadglide Ultra in for my 5k service and they found the same thing. Came and got me to explain what was going on and what they were doing. Very happy with Harley Davidson and them stepping up to fix an issue all under warranty. Thanks for sharing this!

Wait so fluid containing mechanisms that experience temperature fluctuations need to be vented or they will push past seals!?!?! Whoever discovered that at Harley deserves a raise!!

VENT KIT ON ORDER FOR MY 2018 FREEWHEELER, DISCOVERED PROBLEM AT THE 15K SERVICE. HOPE THIS WILL FIX IT FOR GOOD. GOOD VIDEO, KEEP UP THE GOOD WORK. DAN

Keep an eye on your engine oil now. Many have had an issue of transferring from the engine to the primary after the primary vent was installed. I’ve installed the Greg Williams clutch rod on my 17 and my 19 to stop the transfer from the transmission to the primary. Over 60,000 miles between them and no further issues. Good luck.

My friend just bought ugs 2020, i will forward this video to him. Thanks a lot.

Owner; " I always keep my bike clean I'm always cleaning it" mechanic; " not down here! 🤣🤧 great video!

A tip.for anyone wanting to fix it themselves. The vent hose is very soft and flexible. Put the hose over a bamboo skewer or similar thin stick and it will push right through the hole you drilled very easy. Fishing it through with pliers is a pain due to the cramped space. My method took seconds.

I have one of the first 2017 M8 to hit western Canada and it transferred up to 16 ounces in less than 500 miles. That’s right, five hundred!!! My dealer dicked me around for over a year telling me it’s impossible and tried the little deflector shield and a couple other fixes wasting my time and money. When it was first discovered that it was a vacuum being created in the primary side, I suggested we put a vent in there to alleviate the vacuum. They said it’s already vented through the transmission via the shift rod! No shit. THATS WHERE ITS LEAKING DIPSHIT!!! I installed Greg Williams pushrod and it completely solved the issue at around 40000 miles. Finally. Then when I brought it to dealer for a recall, they installed this vent without asking me and said “your problem should be solved now, Harley discovered this vent kit works” I showed him the email from over a year earlier where I suggested a vent and they laughed at me 🙄 It seems you have a good relationship with your dealer and that’s great but I haven’t found one yet that I trust with my bikes. This fiasco was the last straw for me an HD. I’m done with bran new bikes and dealerships.

A pointer to anyone drilling where you dont want chips to get. Coat the bit in grease

I did mine at home when kits weren’t available, found one in Europe I ordered. Worked to fix my issue

This is why I keep running my Shovel it seems even after all these years HD still makes a bike you buy than have to do a shit load of upgrades to get it right. I've spent the last 40 years slowly getting this one bike set up, belt drive primary, baker 6-spd, S&S E-carb,ported & polished heads, solid lifters, roller rockers so and so on, can't believe they're still running a chain primary.

I have a new CVO Limited that I have to have evaluated for this at my next service.

My 2020 Street glide came with that vent installed from the factory

Had this done to my 18 CVO RG as oil was transferring.

Keep eye on it still. Many people still have the problem after the vent install. Greg Williams push rod which shone can do is also a good fix.

Keep a close eye on your engine oil level now, been hearing after the vent kit you can start losing engine oil into the primary. I had the transfer issue and I used the A1 cycles larger push rod to prevent the issue and has worked great now. Just heads up TJ not sure if or when but just keep close eye on your levels. Ride safe ol buddy!

My 19 came with it. It doesn't fix the problem if you ride your bike hard. My solution was Redline Gear oil heavy shock. It's pink color also make it easy to know if it's still according. It's working for me.

Had my 2019 RGS done

My 2019 transfers oil like a m'f'er. At 10K miles, the factory absolutely refused to put in this vent unless I rode another 10K miles and had it verified at least twice by the dealer. THEN, and only then would they grant me the privilege of paying a $100 admin fee to do this $200 repair. I'm left with having to do this myself, and am grateful to you for this video, unlike H-D who sucks hairy ballsacks.

Had the same issue with my 17 SGS and they put in the Primary Vent Kit. Good to go.

Great video

My 19 Roadglide ultra had this problem. Had the vent kit installed under warranty. Haven't been able to ride yet because of my snowy area. Heading to florida soon, will keep an eye on it to see if problem is solved.. my trans oil wasn't showing on the stick when I found the problem..

My 2018 road glide has the oil transfer problem but it’s out of warranty and they say I have to pay for the repair. Stupid I have to pay for there design flaw.

Having a very hard time finding nutural is the first sign your primary is too full. My second sign was engine detonation. It was putting so much extra load on the engine spinning the primary it started spark knocking under heavy acceleration. I had 44oz of fluid in my Primary and only 14oz in my trans. Bike is still under warranty but I can't trust the Techs with my bike. $45 for the kit I did it myself. Hopefully the transmission wasn't damaged. Everything sounds and feels ok now. It took much longer to check the trans for the "witches hat" than it did to install the primary vent. Now is the time to Install aftermarket exhaust because I basically had to just about remove the full exhaust to get the Transmission cover off. And afterall that work my 2019 RGU did NOT have the hat. And Whatever you do, do not use loctite on the Primary Bolts! You will strip out the threads next time you remove them. Use a little anti seize.

My 2019 Road glide and this problem. I had that fight with the dealership, so I printed out the TA and showed it to them. They installed it under warranty. Unfortunately a month later I suffered a stroke which wiped out my right side. The bikes sat for a year before I sold it and I can't say whether it fixed the problem. I don't ride anymore except an electric wheelchair.

If this is a known problem why can't harley just make this a recall issue .

Has anyone found any damage done to the transmission after they’ve done a few of these. No one seems to be mentioning anything regarding the possibility of problems as a result off this issue. Great video.

Lucky I not had that problem.

Do yourself a favor brother and change out that shifter linkage. $22 on amazon to one with heim joints. Might save a trip one day. Factory one is garbage and has left a few buddys on the side of the road. Just lookin out. Stay safe brother

Shouldn't this have been caught during development testing?

My 2019 SGS had the same issue. I checked the oil in that dude one day before a ride, no oil in the transmission. I was 630 miles past my 1000 mile service. Called the service manager Nick, He asked me not to do anything to it, I trailered to Texarkana and they put the vent kit in, no charge to me. Now I'm gun shy, I check the oil everytime I ride now. I was like, no oil leaking on the shop floor, I'm good, no need to check the oil. WRONG, I didn't know it would shift around in the engine. Sure glad my transmission didn't lock up on a ride and kill me.....

I still see metal cihps inside where they drilled the hole..and they are gonna button her up

Yup- 🤠❤️👍🏻

Install a Greg Williams clutch pushrod and problem solved !! NO need for a hole to be drilled in your case !! I have 30k miles since the rod install, not a drop of transfer since !!

Thanks for posting. I wonder if HD does any testing? The M8 engine has had multiple problems. I own two TC88 bikes that I am dealing with cam chain tensioners. Design flaw that HD did nothing for their customers. I am a former die hard harley guy that will never buy another harley. Drilling holes in a new engine, how crazy is that!

Some of the 2017 107’s had this issue as well, am I right? I’m on a 2018 Road Glide, and I’m tired of worrying about the possibility of this, not to mention that I would love to install a Stage 3 kit. However, I’ve heard too many horror stories. I think I’ll just get the vent and stick with a Stage 2.

I was hoping to see how you deburred the edges of the hole you drilled.

Did you change the push rod also?

Pardon my ignorance but how do you detect this problem? How you know is transferring oil?

There should be a HD recall to correctly fix this problem.

Did the check engine light come on

Keeping my twin cam...ty

Has this been corrected for 2020 models?

What noise were you hearing?

2020 RGS 114 / Does this have anything to do with pressure buildup in the oil crank case or or is it a total different problem ??? Second question if you already have the vent tube should you also get oil cap ventilator pressure release cap so you won’t get pressure buildup in the crank case ????

I JUST HAD THE SAME THING HAPPEN. THEY INSTALLED THE VENT AS WELL

Those guys are obviously pros but did it still make you nervous watching them hand drill into the case like that?

would this be a problem on the 2017 Electra glide ultra? I've notice this past week I'm a quart low and no leaks. So I filled it and the light came on on the way back from a 2 hour ride. Checking tonight if low hopefully a bad sensor..

I noticed that Harley Davidson seldom issues recalls for stuff like this. Other manufacturers issue recalls all the time for smaller shit. You fork out over $20k for a bike and it has more issues than my $6k Kawasaki 400!

Put me off trading up to a 2017 Streetglide. Seems im stuck with my 100,00 03 Nomad. Bummer.

"This bike?!?!" Hahaha!!!

Um my 2018 does it also. I dont believe anything Harley or there techs say anymore.

What year, if ever, was this mod factory installed?

Anyone know the date when this vent started coming from the factory? I have a 2019 Road King that came with it, no problems so far, called Harley customer service toll free number, they said May 31 2019 is my production date. If those shopping for 2019 left overs could know a specific production date, this could help them avoid potential problems.

Just paid $430 to get this done at the dealership

Is there going to be a recall or do we have to wait until it goes wrong?

Did he say there was a device bulletin?

Does every 2017 have this issue?

My 98 evo doesn’t need that! ;)

Hope that fixes your problem. Another reason I like my Sportster, they're probably the most reliable, trouble free bike Harley Davidson makes.

Shout out to the guys at White Lightning Harley in Chattanooga. I rode in off the street (no affiliation with the dealer - I live in Louisiana) to get a 10K service done on my bike and they made me aware of this issue and fixed it under warranty while I waited.

Harley has come along way with quality control but it seems what one dealership will address others will deny. Its always something and Im in the market for another bike but it wont be a new Harley. To make it dependable you have to put on a few thousand dollars of aftermarket parts or keep going into the gear box or primary to make sure its not going to self destruct . I always rode Harleys and when I was young we thought we were cool if we worked on our own bikes. If im paying 18000 dollars to $30 thousand for a bike I should not have to make upgrades. Plus service fees at a Harley dealership are ridiculous. I feel I have to go back to early Twin cams and rebuild them to get a bike I need. Or cop out and buy a Japan motorcycle. Just saying

Is this an issue on the milwaukee 8 softails too? If so is the fix the same?

Marked safe from Harley Davison 👍

Does anyone know the Service Bulletin number. trying to figure out if I need this done or not...’19 SGS, Thanks!

I just discovered oil coming from that area on a 11/20 built road king special. Anybody else had similar?

There is a bypass for apple CarPlay now. Law abiding biker has the file name on his channel.

Everyone is using a term, “Transfer Issue,” I started using Red Line Gear in my Trans during my last Three Hole and now 1K miles later I am putting a Man-O-War Sprocket on my Road Glide. I noticed, both times, the red gear oil seeping through the clutch adjustment 🔩. Not a fan of venting in front of the rear wheel, I’m a DK Customs Catch Can guy. Chris from Cycle Solutions called this oil flow from Trans to Primary, “Migration”. Does anyone have the same issue with models after 2019? Because the Service Bulletin “M1492” only references 2017-2019. SKWID ET1(SS/SW/MTS) US Navy, Ret. 2020 Fat Boy “Killmonger” 2021 Road Glide “SilverBACK”

What did the noise sound like?

Go watch traveling tall’s video with the Zipper folks.

It is under warranty. So let Harley fix it.

I took my bike for the 1k service and they told me "we noticed the fluid transfer and installed the vent tube" but I looked and they didn't do shit

Problem with Harley is its many years before a new year engine replaces a very old one. Band aids are used until then. Other bike Manufacturers develop new engines more frequently to address problems faster. Euro 4 and now Euro 5 emissions will force Harley to make more frequent new engines designs and hopefully less band aids.

Seems he should have cleaned ALL of the shavings out before putting the breather tube in.

I don’t know if this is the issue with my 18 RGS but after 9500 miles all of a sudden I have a oil leak from the primary drain plug.took it to Harley for a 10k service and told them about the leak..nothing..got it home after a 50 mile ride guess what oil on my garage floor

If the bike needed it that bad why did the factory not put it in when they made it. $30k for u to fix their fuck ups.

Only took HD 2 yrs to fix the issue..probably why I got rid of my 17' Rgu..got a lot of excuses but no resolution..at the time I owned it... I had 15oz of transfer after a few hundred miles..funny my 92' Flhs Evo..never had this issue..😊

Was stolen bike located?

Can't build it right from the factory. So they put fucken Band-Aids on it at the dealership. I was going to sale my Twin Cam. But after watching a bunch of videos on this new engine no thanks!

How incompetent assholes at Harley Davidson. This has been happening since the 2017 models and they should have just done this from the beginning PERIOD. Specially for the price tag on the bikes!

Not everything from west is the best.

Yes T.J. you are right. Don't try this at home. Especially if you're like me. Mechanically challenged. ; )

I ride Harley Davidson lowrider s

Ok i guess any kind off bike can have problems . I have had different bikes. Just a new bike should be free of problems.

Unbelievable.

The vent doesn’t work! Thicker clutch rod fixed the problem!

I think you need to be a rocket scientist or pay the stealership 5 hours labor @ $110/hr for a fifteen minute job to fix this.

Took him 30-45 minutes to put that tube in... But he's still gonna charge you 2 hours labor!

They wont issue a recall, why you may ask? Because they ABSOLUTELY SUCK, look no further than the famous 1999-2006 Spring cam chain tensioner failures that were disintegrating the plastic shoes and causing engines to blow up INCLUDING MINE!! I went back to a tried and true Evolution powered Harley Davidson. RIP HD 1903-1998 🖕

I have a 2019 RG Ultra that had the vent installed at the factory. Didn’t have any issues, was running a feuling parts vented dipstick as well. After about 2,000 miles started sumping, so H-D Warranty paid for my motor build. Check out my 128” on Instagram @baer_glyde

A flaw like this is pretty fucking big. IMO there should be a proper fix aside from drilling a hole in your primary.

Took my 17 M8 to the dealer for the samething told me moco would not cover the vent kit wanted me to pay out of pocket had it in before for oil sumping and this time for transmission oil trasfering traded that oil sumping trans oil trasfering M8 piece of shit for a 96 cubic in cable clutch they also tried to tell me to check it hot standing up lies

Pay 25000.00 for a bike and a piece of rubber "fixes" it.What a joke HD

Sad as a Harley fan to admit they haven't made a reliable engine since the EVO. They seem to be engineering a few thousand dollars extra each year for service department revenue. They should replace every single defective motor they put out under full warranty no questions asked. And this stupid repair... a cordless drill taken to a primary housing, then they try to suction out one side of the equation, what about all the shavings on the other side?

Drilling a new engine and a rubber hose??? That's HD solution? What kind of engineers they have designing and testing engines??? Now we have to trust that creepy solution miles and miles??? Come on guys!! Are we gonna accept this??? This solution is a passing by when you get stucked in the middle of Namibia and gotta get going anyhow, but not as a big and great Company solution.... Just can't believe it... D'ont count on me anymore MoCo... Love your bikes, but to ride them, not just look at them and am not stupid... GOOD BYE.

So the m8 motor is shit if it’s constantly getting “fixed” per the service technician. How the fuk does HD still sell when this motor is garbage

Spend that kind of money on a Harley, then constantly spend more money on upgrades and fixes really? HD stands for Huge Disappointment

Why Harley won't resolve this problem and several other M8 problems is beyond me. I will never ever buy a M8 (hope my 2014 Heritage last for ever). This is giving Harley a bad rep and seems like they don't care. with this said if they go under it's their own fault.
