That's good to hear m8!
I would say you did not pull your clutch in many times? I would guess as it seems to migrate via the clutch rod that goes through gear box to the clutch.
on another note I saw A I M have a large piston for the hydraulic clutch, would give you a sort light pull to shift gear.

The using the clutch theory has been tested by a bloke on the US HD tech forum at some length. Upshot is, it makes no difference if you hardly use the clutch, a bike prone and currently transferring will transfer just as much as one using the clutch a lot........
Many folks report that the transfer issue can be periodic. It’s very strange. One constant is that the Williams pushrod fixes it very time.....so far!

it would be going past an oil seal. do you have a picture of the Williams pushrod beside the stock pushrod?

The migration pathway is straight down the main shaft. There is of course, no seal. Didn’t take a pic of the Williams rod, but they can be found on Facebook, which I’m not on. But basically, it’s almost twice the girth, but with a machined flat edge along the entire rod so the primary can still breath. The extra girth greatly increases the pushrod surface area within the mainshaft. Enough to prevent any migration effects. I’m guessing the larger rod sets up a completely different pressure/eddy/vortex regime in the trans/primary which nullifies transfer.

Just been in contact with Greg..Pushrods on the way here soon hopefully

I say 'Pushrods' because I was talking to a mate the other day also with a 17 RG...I asked him to check the trans level, hes at 7800klm..guess what he found when he pulled the stick?..

Sweet fuck all? but I cheated........I read your post on the US forum......anyhow, once it arrives, it takes literally 5 minutes to fit, then your transfer problem is over and you can do those long trips not worrying about it.

Got my clutch actuator recall parts in the other day too...Dealer says bring it in anytime...Just after I mentioned the migration issue...That the dealers have never heard off...just sayin...be funny as if this recall fixed it ay lol

The recall has nothing to do with the transfer issue. If they say they haven’t heard of it, print off TA0022, which I’ve posted in this thread and shove it under their nose.......then ask em why they don’t read their own technical alerts.

Have TA0022 right here, just sayin that it would be 'coincidental' if the migration issue suddenly dissapeared after the clutch recall....that included having a modified pushrod fitted...that noone was told about ha!

A picture I found of the Williams clutch pushrod against the Harley rod.

Yes a thicker rod is best

The rod also has a machined edge along its length to allow the primary to breath.

"I mentioned this to a dealer here in Perth and was told yes, weve had one do this but it was impossible for this to occur via the clutch pushrod tunnel..."
Helloooo, there is no other orifice joining the primary to the gearbox.

We seemed to have cured this issue on a few high HP bikes we've played with. Three mods will cure it:
1) oversized pushrod
2) vent loop, primary to shift fork hat to trap door.
3) machined trough in trap door to allow S/C cavity to drain to gearbox void.
The issue is this IMO, gear oil gets into the S/C cavity through the support bearing, bearing movement creates oil turbidity, pressurising and expanding oil in the S/C cavity whereby it migrates into the primary. Pulling the clutch all the way in makes the issue worse because the entire oil load in the S/C cavity is forced into the primary.

Apologies for resurrecting an oold thread but thought Id post an update..bikes had zero transfer issues all year since I first posted...
But....Its that time again! Time for the 8000k round trip to Phillip Island that caused the issue last year.

I talked to Greg Williams the other month about the trip and he sent me an updated version of his pushrod to try..Its in the bike right now..

We will see what happens..,
