I would think that thing would leak like a sieve mounted anywhere on the primary.

Sure the oil in the primary is down around the bottom of the clutch basket and the chain... But that's when it's not running. Crank that baby up and the oil is flying!

 

Well you may be right, agree for sure if the breather was BELOW the oil level, I think that if above the level, yes a small amount of mist may weep out. Our air supply lines have inline lubricators so a small amount of oil is injected into the cylinders and such for lube. We really do not have any oil residue to speak of on the breathers. Maybe more mist would create more vented out. I think the OP was looking at this as only a test and not a fix......still think it may be worth a try to see if letting pressure out or vac in resolves the transfer issue.....you go STONEY!

Eagle Out

 

Both of you need to go back and read my post #2265! There are a few differences including different cases, first gear, and the mainshaft bearing.

 

Here is the second trip to the dealer. Here are the parts they replaced. I'm leaving on a trip Monday. Will find out pretty quick it didn't work. And the beat goes on.

 

I hope it works for you. These same parts were replaced on my bike and I still had the issue. In fact, it made it worse. Instead of having to add after 500 miles, the fluid didn't even register on the dipstick after only 260 miles.

 

Ben there done that............ carry oil with you if you plan to go for a long trip. Next is some new top secret part that didn't work for me that the rep put in. I hope you have better luck than I and others are having with there supposed fixes.

 

Have oil will travel. This will only be around a three thousand mile run.
Will be just like the run I toke in June. What a pain in the *** this bike has become. I really like the bike, except for this issue.
I'll take it back again after the trip, I'm sure.

 

Well this just means he's that much closer to the real fix. Like yours, that's when they tell you transfer is normal. Maybe you can ask them if it's normal why do they keep attempting to fix other peoples bikes with the problem?

 

If anyone is interested, I have my own thread there I am posting updates on my experiences with this issue. It can be found here: https://www.hdforums.com/forum/showt...errerid=260476

 

I have demoed three m8s and wish I had the funds to own one of these fantastic machines.
Understand the frustration of oil tranfer but it maybe a long time until there is a moco fix. If I
was so fortunate to own one I would remove the durby cover pull out clutch rod take a flash light look into mainshaft measure a depth for oring groove chock pushrod in drill and dremel small groove go to harbor frieght get oring kit test a oring in groove that fits smoothly install and ride the bike. If there becomes any leak in the primary which I highly doubt have the dealer fix the leak. If this leak really happens at that point I would vent from inner primary just below shiftshaft and run hose back and up frame high than back down below trans.
