Does it cause issues? I can't see this being an issue just because I put a vent in the primary side, seems strange.

I am all for doing what needs to be done but it seems like a lot of work for something that may or may not be there and may or may not make any difference.

Primary vent installed at 1,000 mile service. I just did the 10,000 mile service last week. Zero transfer in 9,000 miles. Before the vent it would suck the stick dry in a tank of fuel.

The deflector was designed to collect trans oil and "sling" it around, rather than migrate along the pushrod and into the primary. Problem is, it works very well at collecting oil, but not slinging it, so it makes transfer worse - and also tends to create transfer issues when there otherwise shouldn't be (i.e. when the primary vent is installed).

Per the vent kit instructions (https://serviceinfo.harley-davidson....46960640898220), to remove the deflector, it says to remove the transmission side covers - any 2017+ service manual will show how to remove the outer transmission side cover and the inner cover (Section 8.5, page 8-7 in my 2017 manual, as shown below). The deflector just slides off the pushrod.

Took it back in and asked the service writer if they indeed removed the deflector. He became argumentative and insisted the oil deflector would not have been in the bike unless it was previously installed as a fix. I insisted that all 2019’s came standard with the deflector from the factory. After ranting about how I was wrong, he proceeded to bring up the dealer parts fiche and show me all the places the deflector would be listed. After showing me the clutch section, primary section, and transmission housing section, I told him “now bring up the transmission gears” where I pointed out the deflector was listed as OE equipment. He ate crow, grabbed the mechanic who did the work who also proceeded to bitch about it, but opened it up and took out the deflector. Since then, no issue with migration. The mechanic did however gorilla the f’n derby bolts back on after checking the fluid level in the primary, which I think he did on purpose but that’s another story.
