What did you do to Your Tri-Glide Today?

[DK Custom Products]

Seems like a straight forward install ... here's hoping the vent solves the issues. Great video, looks like it maybe helpful for us to understand exactly what the vent "fix" does and how the dealers will install it.

Playing devils advocate, will you guys doing this void the warrantee? Guessing not since it's a Harley Kit that is available for the general public. Also, you have a video of the actual install that shows you installed it correctly . I'm wondering if maybe Alan should do this to his 14 ... even if there is no evidence of migration? Might be a really cheap insurance policy, especially with my chosen fluid combination.

So am I understanding that the primary developes a slightly lower pressure than the transmission? Or maybe even a vacuum? This change in pressure is what causes the migration? The vent prevents that and thereby slowing or stopping the transfer? That's my guess since putting a vent on the primary side would have to keep the primary at atmospheric pressure pretty much all the time. I'm also guessing the transmission has some sort of vent also ... or there may be a chance the fluid migrates the other direction.

Seems to be a pretty interesting fix. I'm just curious as to why the migration didn't show up until the 14's and more so on the M8's. I know it has something to do with the hydraulic clutches ... so the hydraulic clutch is causing this change in pressure? Maybe the cycling of the clutch with the hydraulic fluid is acting like a pump and creating a slight vacuum? Does the installation instructions give any "theory as to why fluid migrates"?

One more observation/question (sorry, it's how my brain works ... drives me nuts) ... so if your bike/trike is experiencing the migration, I'm guessing you pretty much have to keep the same fluid in the trans as you have in the primary (Syn 3)? For instance, putting shock proof trans fluid in the trans wouldn't be a good idea ... pretty sure the clutch wouldn't like that ... even diluted (5 oz of shock proof mixed with the 30 something oz that are in the primary). Inquiring minds (at least mine) want to know .

Glad I'm not the engineer that had to figure that out ... LOL. Of course ... my thoughts on this could be in left field all together ... ... I can see me setting up test engines with gauges on both sides and recording the pressures on 15 minute intervals. I picture lots of hoses running all over the place, me in a white lab coat and thicker than my normal glasses ... pocket protector with pens and even a small thermometer and other highly technical "stuff" in there. Maybe an oval shaped patch on the back that says "A.B. Normal Engineering".

I have warned y'all about my brain ...

Took me a minute on the abnormal engineering.

Yeah, straightforward install. No, won't void my warranty. HD part, done per HD instructions.

Instructions give no reason for the vent kit. But the theory is that as the primary warms up and cools down there is a vacuum created that pulls oil from the transmission. Some have said that the vacuum is/could also be coming from the engine main, into the primary.

As Jack mentioned, this vent is not addressing the cause of the migration. Obviously there have been millions of engines that did not migrate and did not have a primary vent.

To me it does not matter. I just don't want my trans fluid going into my primary, and hopefully the vent will stop that.

I am running redline shockproof in the trans and syn3 in the primary. While a bunch of redline (far more than 5 oz) has ended up in the primary, so far I have had no negative results (clutch slippage, etc.) from it.

Alan, I doubt putting your H D vent kit would void a warranty tho a phone call to your dealer should answer that

The hydraulic clutch actuator piston shrouds the push rod blocking the fluid from draining back past the trap door bearings like it should

Too much of any fluid and or fluid mix is going to give you clutch disc problems, since HD is now selling a new fluid for both primary and tranny we will see how this plays out

The trannys have their own vent tube, the new fix HD has is IMO a band aid, they need to correct the original problem IMO as to the transfer issue ( cable pull clutches do not exhibit this problem as of this date) H D knew of this as early as 2014

Yep, not addressing the root for sure. Never had the problem on the '14 and thought I would get away without in on the '19. No such luck. Hopefully it's behind me now.

So in your opinion, if I have note seen this migration in the 6k+ miles ... I probably don't need to do it ... worse case, I believe it's a slow transfer, so even if it starts, it's not gonna cause a failure of either primary or transmission. Then I could do it. I carry ample tools to "move fluid around" on a trip ...

Weather was gorgeous today ... mid 60's ... sunny and not a lot of breeze.

Since the broncos are looking pretty sad, decided to do a little ride. Thought a nice 50-60 mile ride would be a good thing ... almost 6 hours later and 300+ miles, pulled back into the garage. Mom was ticked ... guess she had "stuff" for me to do ... it'll be there tomorrow ... LOL.

For most of the ride I listened to an Audible original (freebee) called "The Man Who Knew the Way to the Moon". Interesting true semi biography about John Hobolt, the guy who fought to get NASA to use Lunar Orbit Recovery to get to the Moon. Very interesting study in bureaucracy ... LOL.

So, a meandering ride ... if only a mini one. Gotta do a longer one before I go bonkers ...

Polished all wheels with "Mothers". Then polished the entire trike with Zaino, 2 diff procedures. Got the oil changed. Trying a new oil this time.

Did you take the front wheel off to polish it? I'm procrastinating on the front wheel ... kind of think the only way to do this right (or at least easily) is to remove the wheel and rotors ... just curious if you didn't remove the wheel and rotors, where you able to get all of it?

Should be noted ... I plan to ceramic coat them too.

What oil/filter are you using?

Might have to give it a shot ... guessing just a rag ... not the red ball thingie

Mother's polishing ball is great for this I have one with a 12" extended shaft works really well. Fred

Cleaning my front wheel is a lot easier and quicker now that I lift it using a Motorcycle Sissor Jack. Much easier to spin the wheel, than roll the entire trike.

[PosseRider]

I have that Red Ball also,but did not use it. As small as the wheel area is,just a rag works well. Jack up wheel & rotate. Easy Peezy

Okay ... so now it comes down to getting off my fat a$$ and doing it ...

After almost a week of the temps bouncing between the teens and low 30's, it has been really nice the last few days riding in the high 40's-mid 60's.

Rainy today ... by some accounts, we could get S _ _ _ ... we'll see. So ... today I went out and gave the Fat Bottom Girl a pat on the b$tt. Just for the PC crowd ... ... I asked the FBG if I could pat her b$tt and she said yes ... at least that's what I "heard".

Today and the past two weeks 30s & low 40s with rain sucks in Mass East coast. Tomorrow looks like it mite hit a high of 48 I riding in to work. Mite be my last hora for this year? Thanks Giving weekend start tear down. Adding new 585 SS cam's cam plate & pump with new adjustable push rods. Mighty Mite fans new Polk Audio MM1 speakers , Rockford Fosgate amp and USB power port for the wife. All planed for this winter up grades. Maybe new rims for Christmas have to wait an see fingers crossed!

So, I went out to the garage and Gave the Fat Bottom Girl another pat on the rump ... got admit it ... I'm starting to like this ...

Rode it to work this morning (27 degrees). I'm annoyed that the $280 Harley heated grips do almost nothing. The $50 Symtec Heated Grips that I installed on my FJR1300 work just fine.

I talked to my parts guy and said that I need to swap them out for another set. He said that I have to have their service department verify that the grips are defective since I installed them myself.

Went to the dealer, had 2 software upgrades done. One was for the traction control, the other was for using the cloud app, that I don’t use. They also replaced the chrome bezel for the speedo as it cracked, and they ordered a new speedo as moisture is getting in leaving some staining on the inside of the glass.
