well we know the primary is much narrower on the 17 just wanted to throw that out if it would make somebody in the know think a little more

 

Simply put, Darren stated opening up the vent a tiny bit appeared to fix his issue. You agreed that this seemed plausible and went down the road of gasket production theory.
By association you've bought into the idea that opening the vent 1/16 the problem could be possibly be eliminated...

So Steve tried similar by opening a hole 10 times larger and closer to the actual would be transfer device (main shaft) and for him it did not fix the issue.
For you, suddenly this is suspect because of the interior size of the trans somehow becoming a factor and frequency theory things.
I find that if you support Darren's approach, by extension you have to support Steve's as well. Not saying either Guy is right, but they are doing the same kind of testing.
Can't say Steve's approach is wrong just because you don't like him. I mean I get that some people don't like him. But don't let that affect your critical thinking...

 

My bike has no measurable amount of transfer. This is interesting to me because it goes against many of the theories given as contributing factors. .

I did a cross country ride with a very large group of riders, I logged over 6200 miles on this trip.

Many of those miles were in a tight pack running 60-65 in 5th gear and using a braking technique that uses only the engine to slow, this required extreme downshifting. [ By the way, the M8 has poor engine Braking ]

I also ran from Little Rock to Wa State solo in four days running 80 -85 all day long.

After this trip my trans level was still within spec.

 

Ok..... quick update.... not a happy update, but an update nonetheless.

Dealer dropped off my bike at work at 5:30 yesterday as I was getting off work. Climbed on it and rode it 47 miles home. Pulled it to the shop, kissed the wife and pulled the tranny dipstick out, wiped it off, and checked the level........ DRY!! Checked it 2 more times and found the level just barely touching the bottom of the stick. Drained the oil and measured 23oz. Put in the recommended 28 oz. of oil back in, (Mobil 1 Syn 20w50 V-Twin was all I had on the shelf), and rode it 56 miles. Checked the level and it was still halfway in the "X". While I was out, I picked up a bottle if Oil Dye for the tranny. I had asked the service dept if they had put any in and they said no, but I could if I wanted, so I did, along with about 2 more oz.'s of oil in the gearbox to make sure the level was at the top of the "X". So, what I saw was, either the dealer didn't put enough oil back into the gearbox and I read that level when I got home even tho there was actually no transfer of fluid, or there was transfer in only 47 miles. If there was transfer on the way home after work, why would there have been little or no transfer in the 56 miles I rode after changing out the oil? I don't know..... And as far as what school I went to....... read my signature below, lol!

So this is where I am. I have a full tranny with dye in it. I have a weekend of riding planned at Hollister. I have a qt of oil in my saddle bag and some wrenches. I'll let you know what I find out on the trip when I get back. And, I have a bad taste in my mouth after this recent tranny swap, which as I stated earlier, came to the dealer in different shipments.

For the sceptic(s) reading this thread- See Repair Order attached. If I tell you something...... anything.......you can hang your hat on on it. Not a troll or a poser and don't really appreciate having someone elude to that. I realize you guys don't know who the ***** I am or what I'm about, but over time you'll see that I'm just a guy with a couple of bikes that like to ride, just like you. But I am also a mechanic that likes to troubleshoot, wrench, and repair. THAT'S what I do........

 

I'm not sure where Darren stated opening a hole a tiny bit helped. Pic over on HTT shows a pretty good sized slot..

One thing to note is that the gasket sits in a chamber and not inside the transmission case where the gears are. It acts sits in a separate chamber and splits the chamber in 2 to help act as an oil mist separator. The acoustics will be different.

Which hole did Steve open? Did he cut the gasket also..

It's funny that you think I don't like Steve... I consider him a friend.. After all, he likes bourbon.. Its the scotch drinkers you got to watch out for.. I spent a more then a few hours talking to him face to face about twincams, M8 EFI and general BS.. He one of the few that understands this stuff really well..

One thing I do suggest is that when anyone finds a fix, it be independently verified. This is a good case. Too many after market trick fixes for various issues are not and in many cases falsely claimed as good.

 

The paperwork references Recall 0170 and Service Bulletin M-1447 for the stated fluid transfer problem ....???

 

At 3135 miles, here is my oil level. Bike on lift.

 

Recall 0170 is the Oil Cooler Clamp Recall..... that passed with no issues. Not sure about Service Bulletin M-1447.

 

Measured from primary. Bike is an 08/16 build.

 

I bet the initial fill from the dealer was incorrect but you have a plan..would have been nice to have them observe the replacement trans to see if it looked any different from the OEM...thanks for keeping us updated..you are the only confirmed owner with confirmed diagnosis and R&R from the MOCO for this issue that we know of here so far
