So when I read these two statements, my very first thought was... Although you paid $100 per hour for a technician, did the bike wash guy put two oils in one hole???

 

That was my first question to them. Anything is possible. At some point, I just have to take what they’re saying as truth. It would be hard to actually make that mistake as the primary is filled by pouring oil up to the edge of the hole on the left side under derby cover. With the cover sealed, it can be overfilled, but once you crack it open, all the extra fluid pours out. So that hole literally only holds its proper volume. The only way to get extra oil in primary is for it to come from somewhere else when the engine is sealed. If engine oil is correct, and tranny is empty, then that is the only place the primary could have pulled it from.

 

Well that's a good point. I should have thought it through before I opened my pie-hole.

 

Prior to this, I didn’t exactly understand it either. I’ve quickly become very familiar with this issue out need, and fear of being ripped off.

 

Actually, this is what my Service Manager told me my problem was on TWO M8's!
It was my fault since I do my own maintenance.
When I asked how I accomplished this, I got the ol' deer in the headlites stare.

A couple months later, when I took my '18 M8 back for Trans oil transfer, the Sales
manager told me that they had to use less than qualified mechanics because nobody
wanted to work there and make the small pay the mechanics get.

 

NO that would over fill the primary

 

If your on the jiffy stand and not upright you do fill to the edge, service manual calls for 30 wet, I start with that.

 

Yes, in fact, when on the jiffy stand (on level ground) 30 oz. in the primary fills right to the edge of the opening.

 

Well took my 2019 electraglide in for 1000 mile service and they checked for oil transfer, yep I have it and they had to put in a primary vent kit.
They said it involved drilling a hole in primary cover. Not too friggin thrilled about this crap!

 

Not the primary cover, but the inner primary. You will not see the vent unless you're on your hands and knees looking for it.
