    Thanks Oz Dan,I agree to fit the later oil pump,I have been suss on the original oil pump that was fitted in the 2017 107 for a while

    I suspect you are quite right to be a little suss of the very first pump like I too had......my bike is running noticeably cooler and it’s much quieter. It also will return all the oil to the bag in under 30 seconds whereas before I’d have it idling for 2-3 minutes to get a proper oil level read.....

    And I’m yet to hear of a single MY20 bike sumping.... let’s hope this issue is dead with the MY20 pump.....

    Hopefully this new pump will cure the sumping.

    Where did you buy the later oil pump from?
    My motor seems to be noisy around the cam chest,hydraulic lifter area,perhaps fitting the later oil pump will cure that,I'm not sure
    I have already fitted the Screamin' Eagle SE8-447 cam a little over 12 months ago,so I could check the lifters etc while fitting the new oil pump.
    I take it the same cam plate etc can be used with the later pump?
    Thanks for any advice you can give me 

    I ordered it all through Wackers (HD dealer).
    The noise might be worn lifters/cam lobes from the suboptimal first edition pump so make sure all is checked and replaced if necessary.
    The new pump requires a new Cam plate, old one doesn’t work, nor does the last of the MY19 plates. Everything is available as a kit.

    For oil cooled M8, part number is 62400247.

    Good info Dan, FWIW, I've had no noticeable transfer since installing the fat rod I purchased from you. 
    Did you upgrade your cam bearing when you had your stage 2 done?  I'm considering the torque cam and upgraded pump for mine but don't want to spend a few hundred more on one time use tools,  so would leave if ok to. 
    Thinking the SE adjustable pushrods and lifters also? 
    Cheers

    That’s great to hear Doc......glad the fat rod did it’s thing......mine too has put transfer to bed.
    The cam bearings were not upgraded when the Stage 2 was done......my understanding is it’s not a requirement with the 447 as per HD tech bulletin for the procedure. Adjustable pushrods did go in - they are part of the M8 Stage 2 Torque cam kit......

    They use the original lifters. 

    Once you do the new MY20 pump, and once all is good in the chest, hopefully sumping and premature wear will be non issues......time will tell.

    Hopefully there is nothing wrong with the lifters and more to the point the cam lobes,I fitted the 447 cam a little over a year ago,it's a nice street-able cam
    If the lifters are worn I think a set of S&S lifters will be the go.
    I'm having nightmares about what I might find in there :( :)

    Being a new engine platform, I bought an extended warranty through Morgan and Wacker and its now paid for itself and some.....good luck with it Ababa......let us know how you go.

    Don't know much about posting a you tube video on here but if you go onto youtube and look up Doc Harley oil transfer there's an interesting 11 minute video I reckon on this very subject?
