    "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..,

    Interesting .......my heritage 114 has 5,000 kms on her, checked it last weekend, nothing bad to report. All levels are correct.
    Am I alone on this?

    Its a tourer issue Neale, cable clutch don't do it, stopping the transfer is an easy fix anyway, Harley won't do it properly but a proper fix has been worked out for quite awhile, the only issue you may have is sumping, but to date I can't pin down a softail M8 that has even thought the MoCo admit they could. Or rather they did and now it never happened. Wouldn't put me off buying one of I was in the market.

    As above, it’s a hydraulic clutch issue only, so not applicable to M8 softails Neale. In regard to potential sumping, there is a new 8 lobe pump (MY20) which scavenges 40% better than the previous version......looks to be the winner so far. It’s available as a kit, part #62400247.......I’m getting it installed Monday at Wackers - haven’t had sumping issues,  purely preventative insurance. 

    PS - part number not listed on public HD website yet but dealers can look up and order ($226)......they have em in Sydney if anyone wants to get on board.

    Be interested to see how the new pump goes Oz Dan.
    I have a 17 107 SGS and the original oil pump, from what I'm reading it is adequate,adequate isn't good enough really.
    I have the version 2 of the Williams rod and no sign of transfer since I fitted it and a dealer fitted primary vent,
    My bike had a history of transfer and the dealer fitted the vent at no cost to me so I thought why not,nothing to lose

    Mate I haven’t had transfer or sumping but I love my M8 king....I’m keeping it till I can’t stand up, which is why I’m doing proactive preventative maintenance .....after a fun twin cam, this is a wicked bit of kit which is miles ahead....and if it wasn’t for fn internet forums it would still be stock lol. But here we are.....I too have the Williams Mk11 and I’m doing the 8 lobe - I figure if it scavenges 44% better and I had no dramas with the original pump I gotta be gold with it.....I guess what I’m saying is there will be likely nothing to report.....didn’t have issues pre, surely won’t moving forward.
