They had a notice of some kind in hand when they worked on mine a while back. So far no more migration. 4,500 miles after they worked on it. Leaving in couple hours on a 7-800 mile ride.
In all the years I have been riding Harley, I have never heard a dealer say "That's normal, they all do that". A Ford dealer did one time.

 

And just because a piece of paper suggests it's happening to all bikes doesn't mean it is. Most people probably don't even know they may have an issue. I for one never said or speculated any kind of numbers that do or don't. I have however stated that it is NOT happening to my 2017 CVO Limited so far. It has 6300 miles on it and the transmission/primary oil has been changed out once. I check the trans level at least once a week and its always fine.

I do honestly believe it's an issue at higher RPM's for extended periods of time which I don't do in my normal riding. I do shift at 3500-4000 rpm's quite often though and still no issues. Put it on a dyno and crank her up, ya maybe but why would I? I am going to ride more and worry less and see what happens. For those who can't even ride their bikes like Steve I would be furious that's for sure!!

 

If this has been happening since '14, I wonder if the fix that the Germans found of using the '14 clutch pushrod pieces does actually work?

 

yup..I and a 'few' others that actually 'own' M8's kinda' sorta' like them...but you on the other hand, non M8 owner, and TC lover, spend a lot of time on the M8 Forum bashing M8's, very strange behavior.....real piece of work you are

 

AFAIK, this issue started with the M8 trannys. I don't remember ever seeing it mentioned on the Rushmore forum and my '15 Limited certainly doesn't do it.

 

Kinda sorta? Bit of an understatement my friend. By far the best bike out of the six I have had over the last 28 years or so. And far better than the never ending pinging of the TC 103.

 

I guess my Limited with the water-cooled 103 is the exception. I've never experienced pinging or detonation of any kind, even on 100+ degree days.

I'm a pretty conservative rider, though, so that may have something to do with it.

 

We seem to have two different groups on this forum. The first group (we will call them the fan boys) love their Harleys and have never had a problem with them. Since they don't have a problem now they doubt that anyone else has a problem either. We will also include all the riders who take their bikes into the dealers to do fluid changes. They never check their transmissions anyway. They could be transferring fluids too but since they rely upon the dealer to discover this, they are clueless. These guys don't know what they don't know. This is by far the biggest group. They did not buy a new Harley to work on it, they bought it to ride. They expect it to not have any design problems.

Then we have the folks that actually purchased the bikes and are having the transfer problem. This group probably discovered the problem because they prefer to do their own service and maintenance. These people are adding transmission fluid on one side of the bike and sucking it out of the other side of the bike. This has been going on for 5 months for people like me so naturally I am upset. What upsets me the most is the fact that the MOCO seems to have adopted a rather cavalier attitude toward this design or manufacturing problem.

The recently published Technical TA0022 from the MOCO lists the CAUSE as "oil is transferring from the transmission cavity to the primary cavity". Well duh.... that is obvious. What we want to know is WHY it is transferring and we want them to fix it on their dime rather than just ignore it for 24 months (like they are famous for doing).

For 2017 and later vehicles the TA0022 says under the ACTION paragraph: "Check the primary and transmission oil levels and adjust the oil volumes as needed. Verify oil levels again in 1000 miles. That is no fix, that is merely a kiss-off.

If they don't know why it is transferring after all this time then they need to seek outside engineering help to determine the exact cause and then come up with a fix for all the bikes that are experiencing this phenomenon. My greatest fear is that the MOCO is going to try and sweep this under the carpet and hope it all blows over before they have to issue a mass recall to fix these transmissions.

 

it was sarcasm

 

I normally don't ride my M8 at higher than 3000 rpm's. When shifting I may go to 3500, sometimes 4000. I transferred 6 oz. in 1300 miles. I then topped off the transmission, drained and refilled the primary. (tranny 6 oz. low, primary 6 oz. high). I rode the bike a little over 300 miles. The transmission level went from high mark to low mark. It's not just a high rpm thing. There are M8 owners that have tried to get their's to transfer by running them hard and they still didn't transfer. Conclusion - some do, some don't, some will and some won't.
