The first week after doing this the temps bounced between the teens and freezing. brrrr - we now have 700 miles on this TG and no transfer so far. We'll report back after we cross 1000 miles, and then again at 2000 miles.
1,000 miles and no transfer so far. Looking Good! :)
What holds the vent tube in place?
@@Misty3133 There is a lip at the case side of the vent tube that pops thru the hole. That lip holds it in place from the outside, and then the rectangular end of the tube holds it in place from the inside.
Thank you,I’m not sure if my needs it or not but I’m going to check.Did you let the bike run and get warm before checking the levels? It’s winter here in Massachusetts 🙁
@@Misty3133 Not necessary to warm up before checking the transmission level.
Good Job Kevin and Devin, Thanks for the recognition
I did the same thing, just bought the kit and installed rather than all the hooplah involved in getting it done under warranty. Worked like a charm and I got to buy a new drill bit.
Great video! Thanks for the instruction!
Latest Update- 2850 miles and still no transfer. I'll keep checking periodically, but right now I'm happy with this fix.
Great to hear that, I have a 2019 RGS and with 660 miles it had transferred almost all the oil to the primary, My store is pretty close but like you said it ended up costing me some coin since i requested the 1k service ( time vs mileage). They did install the kit though so like yourself I will keep an eye on the transfer fluid lever.
June 2021 Update, over 10k miles and no transfer. The vent had done the job!
Thank you very much guys. This is exactly what I needed to know.
Good to read, glad it was useful to you. 👍
This vent should come from the assembly line, and it should be a design of the primary case itself and not a silicone hose. Please HD do the things you know you have to do.
HD did start making this OEM in late 2019. Some 2019's and all 2020's come off the assembly line with the primary vent.
My 2018 streetglide had the transfer issue. There is a company out there that makes a thicker clutch push rod that eliminates the transfer issue. So far it worked for a few thousand people. I only manage to put a few hundred miles on my bike than I had to put it up for winter.
Yes, I have seen those. I am hoping that this less expensive method, that is now OEM on current models, does the trick.
@@DKCustomProducts Ah, No. I have a 21 RGL, When I did the 1000 mile service, Primary and Transmission levels were fine. Did the 5000, and primary started losing oil when I took the Derby cover off.I have been checking the transmission, and its in the X. HD told me that the Vent would stop it from transfering. so, looks like I am going to go with the over sized push rod. I belive it made by Greg Williams?
@@Reneemitt If your transmission is in the X (and was not overfilled) then the oil is not migrating from the transmission to the primary. The extra oil in the primary must be coming from the engine (unless the primary was overfilled) and if that is the case, I don't see the over sized push rod doing anything to help that.
@@Reneemitt at this point I would recommend anyone with 2017 to 2019 to just install the rod as a preventative. It's cheap and anyone with half a brain could do this install. Just my opinion!!
My bike was told to me to not have had the vent installed. I paid $100 for the vent install. I just changed oil in all 3 holes and found I had almost no oil in my transmission. The was a huge amount out of the primary. The vent “DID NOT” fix my issue. I am not sure what the deal is here, but there are a lot more videos out there that show the major issue is the point of transfer.
Man, sorry to hear that. First step I would take is make sure the vent was installed properly, and is functioning.
If it is, then the process of elimination continues to find out where/how it is transferring.
Great video, thanks for sharing,
Thank you.
I have a 2015 Road Glide Special. A couple years ago I changed the transmission drive pulley to 30 tooth. Last year I installed the Mueller clutch slave cylinder. Now I am having the transmission oil level mysteriously drop. I have checked, and rechecked, and rechecked and cannot find a leak so am skeptical that the tranny oil level dropping is related to anything I've done. So I'm left to conclude that I am having the transfer issue. I have researched and found that, though less commonly, the '15 Twin Cam bikes also do occasionally have this problem. The primary does seem to be somewhat fuller but not dramatically. But, when you think about it, there is really nowhere else for the tranny fluid to go. I am soon going to change out the top cover of the trans to the old style with the pipe fitting and larger vent hose. After watching this video, and especially after reading your much appreciated updated comments, and, for the low cost, I will be doing this primary vent deal also. Thanks very much.
Yes, it is rare on the Twin Cams, but does happen. The primary vent will probably cure it.
Thanks for watching & we appreciate your comment.
Using the shirt off his back to catch metal filings, that's dedication!

Great time lapse!!
Thanks!
awesome video I had the same problem an just did that install last week
Glad you got it done on your ride! 👍😎👍
Thanks for the comment, glad you are finding the videos interesting/useful.
@@DKCustomProducts extremely useful information saved me time and money
@@Centralthabiker Good deal, thanks for watching. Ride safe!
@@DKCustomProducts yes sir
I stumbled across this video from a few years ago, thank you for posting. Does the primary vent kit apply to 2020 models? I see service bulletin M1492 is for models 2017-2019. I have a 2020 Street Glide and I just starting getting fluid transfer from trans to primary within the last 1,000 miles. The bike has 105,000 miles, but this is the first time it's been an issue. It looks like vent tube this will address the exact issue I am having, but will my local dealer say no because it's a 2020? Or can/should I push the issue to get it addressed?
About halfway thru the 2019 model year HD started putting this vent hose on all M8's. So your 2020 should have one from the factory. BUT, if it does not, then it should be added.
Is your Air Cleaner venting externally? If not you may want to consider venting it externally to keep that blow by out of your intake and build up off your pistons.

Thank you for commenting! MB
So what is causing the primary to create a vacuum and pull the fluid from the transmission? Wouldn’t the outer primary cover seal cavity that you are putting the vent tube in?
Heating and cooling at different rates than the engine and the trans definitely have an affect. There are many other theories on why the oil transfers,,,the clutch rod being a culprit. But it appears the vent in the primary solves the transfer for 99.999% of the folks. It has for me.
I have a 2019 FLHTP 114 had the transfer from the first 1000 mile service... Dealership installed the same kit still have transfer 10,000 miles later.
Wow, that is not good news. You are the first, first-hand report I've heard of the kit not fixing it.
Did they cut the end of the hose after they installed it?
Excellent video! What brand and type of drill bit do you use drilling into the primary case? Thank you.
Glad you enjoyed. We used a general purpose DeWalt bit for metal, because that is what we had. I would not have hesitated to use any drill bit for metal that we had. It is aluminum that is being drilled thru.
Our 2017 Tri-Glide didn’t transfer , the insurance company is holding our trike hostage now they are at the finish line and for some reason will not pull the trigger on the last issue , thanks Farmers Ins.
Hope they get it all taken care of for you quickly! It can be frustrating being without your Ride.
Just pulled the derby cover to put on some more robust clutch springs and fluid was dropping. I know well I didn't fill it over like that when I changed the primary fluid. Transmission was low. 2019 Road Glide Special I bough used with 6000 miles last June. Now has 11500. Now I rread about the "Greg Williams Pushrod"..have yall heard of that?
Yep, that was one of the many "fixes" tried in the earlier days of the M8 before the primary vent was available. More expensive, voids warranty, fixes some, not others. Primary vent is the fix with the highest percentage of success. Very few bikes migrate after a vent is installed.
Does this happen to the later years 21 an up
Looks like that little compartment is sealed off from the mean cavity of the primary. How in the hell is going to work? I put the Greg Williams fat push rod in my 2017 ultra and it worked.
It is Not sealed off. It's working well so far. :)
I understand what you mean about the overall cost. I have a 2019 CVO Limited and with 3400 miles. I have always done all my on oil changes on my motorcycles. But in order to have my bike evaluated I have to let them do my next service. Which is 350 dollars.
Wow, that is what they are telling you? Do you have another dealership in your area that might be more reasonable?
DKCustomProducts no. The other dealer in my Area charges 400.
@@Johnr37us Wow! They have to honor the warranty and recalls even if you do all your own maintenance. All you need to do is keep good records and use fluids that meet or exceed their specs. Over the years I have had well over 10K of warranty work done on various bikes, and I've only paid to have them do one oil change on one bike.
DKCustomProducts They were fine with The fact that I did my first service. But in order for them to evaluate the oil transfer problem on my bike I have to allow them to change the oil at the next service so that they can measure the oil capacity in the two places and contact Harley with the results. And a service is 350 dollars. Now I’m going to tell them not to replace the Transmission oil because even the owners manual doesn’t require you to change that every 5K. But The fact that I’m going to request that they use Amsoil products so it is probably going to make the 350 dollars go up to 375 . See my friend is a dealer and I think I pay around 10 dollars a quart for it and I think the Harley dealership sales it for 14 dollars a quart. When the time I’m just going to pay 💰 it and go on. I only hope they don’t find some other issue with this M 8 engine that requires to have to have The cases split are the cylinder to be removed to fix another problem. Because I actually seen a U tube video about one of the internal oil sprayers that are on some of the M8 engines that are not tightened properly from the factory. I actually toured the York factory about three months ago and I’m planning on touring the Wisconsin factory in about two weeks. So maybe I need to take my torque wrench with me and show them people how to use one. 😁
@@Johnr37us Wow. I did not use a local dealership to do the warranty work on the primary vent, not because they wanted to charge for the oil change, but because of the back and forth hassle of them checking it before doing the warranty work. I am hearing of more and more dealerships doing the vent without doing the back and forth checking. I know you probably need/want to keep a good relationship with a local dealership, but have you tried calling Corporate and letting them know you have transfer and would like to get it fixed without having to pay $350 to "prove" that some warranty work needs to be done?
Do you have a link to purchase? This solution appears to address the root of the problem more than a replacement clutch rod.
I got mine from Sudyke at this link- www.surdyke.com/PartsMain.aspx?PartNumber=26500027&SubCatID=388&CatID=&Name=&CatName=Maintenance -Courtesy of Jack Klarich
Ed, you get your remote oil filter yet?
Will this kit fit my 2017 FLSS? Had independent shop verify fluid migration.
They are made for Milwaukee Eight engines. You have a Twin Cam Engine. I am not sure if the M8 kit will fit/work on a Twin Cam.
It is rare for a Twin Cam to have fluid migration from the Transmission to the Primary. Could it be engine oil, via a bad seal? Or was it verified that the extra oil in the primary came from the transmission?
KP
My question is,with the position of the vent tube and the fact that it pulls vacuum will it pull moisture into the primary if ridden in a long distance heavy rain.
It will, but very little. HD has been using vents like this for decades with no appreciable negative results.
Theoretically it's pushing air when you are riding as the heat in the primary expands the air in the case. The transfer was occurring when the primary cooled causing a suction that pulled fluid through the shaft. I am not sure how Harley overlooked that and thought a sealed primary would work but they did and it didn't. That being said, this won't be an issue in rain even if it was "sucking" air since the movement of air is very low volume and slow to happen. This is not in a place that is typically barraged with water even in the rain and the curve of the tube will keep anything from flowing up into the primary. Even if some drops get in there they would vaporize before they caused any issues.
@@texasmotorcyclerideradventures so if the transfer of oil happens during cool down, then mileage is not the deciding factor. Wouldn't it be the number of heat up/ cool down cycles that would show results?
@@texasmotorcyclerideradventures So if it has to do with cooling of the primary then why doesnt my 2002 Road King do this,same basic design with the main shaft running from trans to primary with a clutch rod in the center.
@Joseph Marton in my opinion getting rid of the short tube with a bent end,running it up under the side cover may be a better option.
Seems crazy to have to drill holes in a new engine. Does harley do any testing?
Unfortunately, they do leave some of the testing to the early adopters of new designs. :(
any kind of "long distance" testing is done in a lab (Mesa, AZ). The motor isn't in a bike, and they run it at exactly the rpm they're testing. It's great for baseline. but doesn't factor in varying loads from elevation, weather, traffic, weight, incline/decline, etc. Unfortunately these problems are obviously real world use issues that they don't see.
Can I ask does the Rushmore ( street glide special in my case) model suffer from this too? I ask as when I took the primary inspection cover off after i heard a clutch area noise the oil was right at the bottom of the clutch area only just covering a part of the plate? Thanks Ian.UK
It is rare that a Twin Cam experiences this, but there have been reports here and there of primary oil transfer to the trans on TC's. It is very common on Milwaukee-Eight's up until the factory started installing this vent as OEM.
@@DKCustomProducts what year model did the vent become OEM? Thanks ride safe!
@@snakeoil2182 Good question. MoCo started making the vent OEM about midway thru the 2019 production year. If yours was built toward the end of 2019 then it will already have one...it is easy to check, there is a little umbrella shaped rubber hose on the back inside of the primary case if it is already there.
@@DKCustomProducts Thanks for the reply! I've got a 2020 just curious.
A buddy of mine had huge transfer on a 2,000 mile round trip. With local riding he hasn’t transferred an ounce??? He’s keeping an eye on it for now.
Yeah, a lot of guys have seen it transfer, then after time stop...AND vice versa. Also, many guys report that they get higher transfer when running at interstate speeds.
DKCustomProducts yeah he piled on mostly highway miles going slightly above the speed limit 😉
@@michaelwalker3920 Next time he does a 2-3 hour run on the highway, probably will get more transfer. It's a pretty easy job to install the vent, and seems to work well for 99.99% of the folks that use it.
Have the same problem on my 2017 Road King, where I can get vent tube?
All Harley Dealerships should carry them. I got the one for my bike at surdyke.com
@@DKCustomProducts Thank you
I like your company. I just bought a 2020 Low Rider S with the 114. Do you know if Harley has fixed the issue from the factory yet?
Thank you! Congrats on your new ride! About halfway thru the 2019 model year HD started putting this vent hose on all M8's. So you should be good to go with your 2020.
@@DKCustomProducts Thanks buddy.
I wonder if that's something they will just do when I take it in for service
what was the tool used to mark the hole? and where can i get it?
It is a spring loaded automatic center punch. They can be had at most any hardware store, or Harbor Freight, or Amazon for $5 to $10.
2019 Ultra Limited with 15K miles.
It helps, it’s not a true fix. My dealership installed the vent at around 2K miles
I just transferred 6 oz in the last 5K miles. However 50% of those miles where above 80mph, with a couple hundred at 90+, and mountain rips in the 3800- 4800 rpm range for over an hour at a time
Thanks, good to know. 👍
You freakin' animal you!!!!
@@DKCustomProducts follow up, it really never fixed it, I wold notice a reduction in the friction zone at about 4500 miles after changing the primary drive and transmission fluids, which basically resets the levels to spec. Ive been changing trans and primary fluids every 5K, not every 20K as the manual states, because I planned on keeping the bike and hopefully getting 150K miles on it before getting a new one. At about 38K there was so much oil in the primary it took off across the garage with the clutch pulled in when I started it one morning. The dealership told me it was my Flo-Moto lever causing the problem, the same dealership that acknowledged the problem and installed the vent. The dealership reset the fluid levels, added dye and gave me back the bike. About 3500 miles later it again lost the friction zone. Checked the primary, it was over full with dye in the fluid, and the trans was below add. Its now in a lemon law case law suit.
@@distancejunkiemonkey4491 Wow, that sucks you've had to go thru this. Hopefully all works well for you on the suit.
I saw another video where they changed a part on the opposite side also. They called it a witches hat. Did you do that as well?
I did not. All I did was the vent outlined in this video and have had no transfer since then. 👍
@@DKCustomProducts thanks.
No problem! Glad to help
sadly, I believe this fix did not work for my 17 SGS..I had the vent kit (HD) installed about 5K ago...got back from a long haul yesterday and checked and appears (via Transmission dipstick) that still transferring...due for 35k service anyway, so off to shop it goes I suppose.
Man, that sucks. First thing I would do is make sure the vent was installed properly.
Unfortunately, there could also be other factors contributing.
I have a 2019 Triglide as well. How can I tell if this is an issue on my bike? Thanks in advance.
About halfway thru the 2019 model year the factory started installing these vent as OEM. So the first step would be to see if you have the vent already. Look for the little candy can shaped tube, like seen at the 3:27 mark in this video.
If you do not have the vent, then check your transmission fluid level. If it is not full, bring it up to the full mark. Then, periodically check it again. If you see the level dropping over a couple of thousand miles or less (and you have no leaks onto the frame or ground) then you will know it is transferring from the transmission to the primary.
Mine did not transfer much at all the first 1000 miles, but by 4000 miles it was going from the full mark to below the low mark in 1000 miles.
@@DKCustomProducts wow good to know. I just got mine over Labor Day weekend so hopefully it's one from later in the model year. I'll go look for that rubber vent tube on mine and verify. Additionally I just now hit the 1000 mile mark so if mine is one of those that doesnt have the vent then I'll be sure to start monitoring my oil levels to check for any transfer. Thanks again. Really like your channel!
@@kenpacheco4426 Hope you already have one, if not, it's not that big a deal if you need up needing a new one. In fact, HD will install it for free. We just did not want to hassle with that.
Glad you're liking the channel!
I have a 2017 Limited. I’m at 11K miles with zero transfer. An I lucky 🍀 or is this going to be an issue at some point ? I’m under extended Warranty right now to 7-1-2022. Should & will they install this kit if I’m not having any issues currently? I plan on keeping this bike a while so hence I’m asking ?
Can’t tell how and see where the rubber tube goes in ?
Look at the 3:19 mark in the video...it is a close up of where the hole was drilled and the tube was put in. If you are on a small screen, it may help to look at the video on a larger screen, like a computer or TV or tablet.
The how is that it gets pushed/pulled thru the hole. Prior to that 3:19 mark we talk about how and then show it being done.
Pardon my ignorance but how you know the oil is transferring? What happens if you do not address this issue? I have a 2011 Softail Fatboy (Twin Cam 96B) is this also an issue on the TC engines? Thank you. P.S. I am big fan of DKCustom products. Have the air intakes in both of my Harleys.
Check your transmission fluid level on the trans dipstick. If it is lower than when you filled it, and you have no leaks, then it is transferring to the primary. It is HIGHLY UNLIKELY that your '11 Twin Can is experiencing this. A very few TC have experienced this, and I believe they were all in the Touring family, from '14 and up.
Thank you for your business, we appreciate it. Glad you're enjoying some great intakes!
Its only a M8 issue
Have you had issues with the oil pump? Or have any insight on the oil pump?
No issues with oil pump. I believe HD has that sorted. If you have a pre-'19 M8, then you may want to look at the latest oil pump they've been using in the 2nd half of '19 and on the '20's.
Well the big question did it fix the issue? In my opinion you have to put on at least five hundred plus miles to make sure no more transfer.
We don't know yet. It's been 7 days since we did it and 5 of those days have not gone above freezing temps for the high. So we have less than 200 miles on it so far. I'll report back at 500 miles, 1000 miles, and to be honest, until I have several thousand miles on it, I will not be 100% comfortable that it is "fixed".
Yes please do,this is some important info we all could use 👍
Thicker rod a lot easier!
Yes, it is. But at the time, the cost was twice as much, plus I want to see if the Factory "fix" works.
Wow, thanks for the video, i was thinking of getting a Street Glide but why would anyone want to spend $30k on a new bike then have to wrench on it? I will now be going to look at the Indian Chieftain or Challenger. Thanks again for the video.
Disingenuous Indian Troll, by the looks of your channel. Street Glides don't cost 30K, 2020 Harley's already have the Primary Vent installed at the factory, and earlier years the Primary Vent can be installed at no cost or need for the owner to wrench on it. You're welcome. :)
All 2020 touring come with vent. Only took 3 years. Typical Harley.
@@johnlebar6592 Yep, they take their time.
@S. Williams Nope, but that is the way they are on many things...hasn't changed in decades,. and don't see it changing anytime soon.
@S. Williams Thanks. Happy New Year!
Is this a common problem with the M8.
It seems to be exclusive to the Touring M8 models that have the hydraulic clutch. Softail M8's that have a cable operated clutch do not seem to have this issue. With the Touring Models it is not super common, not 50% of them have it. Hard numbers are hard to come by, but my guess is more than 10%, but less than 25%. The important thing is that Harley Corporate saw that it was frequent enough that this Primary Vent is now installed on all Touring M8's from the factory, starting in late 2018. So it is common enough that they are putting this "Fix" on ALL of them now.
@@DKCustomProducts thanks mate, appreciate you getting back to me so quickly. Merry Christmas to you and your family.
@@andrewhughes7379 The same to you and yours!
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 🖕
you have a good point!
Added vent kit and removed plastic slinger. 2019 roadglide 107
Still transfers! Don't have time to jerk
Fu#k around checking fluids every 500 miles. Their engineering staff should be embarrassed! Nothing but a clown show.
1old cat rode them all
Hd no longer covers the cost
Yeah, they fixed it in 2020, so any bikes before then, if they have not had a problem yet, I guess they figured they would not have a problem.
@DKCustomProducts just showed up on my 19 because I changed the derby cover and a half qt of oil spilled out, have no idea what was happening at dealer services, they never said anything so know I have to pay. You can bet if you haven't had it done you need too
@@kevinwilliams8907 Man, sorry to hear that. It is a pretty easy job as you saw from the video...only around $50 for the parts. Hope they treat you right.
Wow... I just can’t imagine working on your new motorcycle all the time what a piece of Crap !! HD stands for Huge Disappointment!!!
My experience has been that the newer years require less work than the older. Unfortunately when they do require work, it may not be as easy or inexpensive as the older years.
DKCustomProducts it shouldn’t be any work ... I don’t even know my service manager, I get my tires replaced every season that’s it
What Junk. Talk about Rube Goldberg.
??? Same thing they've been running on transmissions for decades.
Doesn't solve the problem. Take the bike to the canyons and ride it hard you will see
Sorry it has not worked for you. It seems to work for the vast majority.
Worked for mine. Hard rides through twisties and 85+ mph on long freeway stretches and no more transfer.
Harleys are pure crap. Always have been.
All a matter of opinion and taste...we know yours now.
I’m on my 4th Harley. I’ve never had a mechanical issue ever on any of them nor have any of them ever left me stranded . So your full of it!
Sounds like a guy on a harley took his wife,trolls everywhere
Says the Harley-hating troll...🤣. You guys are transparently pathetic....🤦♂️
