    Re: M8 oil migration from transmission to primary

    If it’s not enough to have oil migration my m8 has now decided to give me oil blowback from my air filter.
    Reminiscent of what happens if you’re engine oil has been overfilled.
    It’s done 3500 miles and was serviced by dealership at 1000 miles. I don’t know if mechanic put too much oil in
    and has decided to level out through the breather tube but it’s going to go back to them for them to sort out and supply me with a brand new screamin eagle free flo filter.
    Lets hope it’s nothing serious and was just overfilled...
    I luv HD

Anyways on Sunday I was packing up to leave and he comes up to me and thanks me for alerting him...he had checked his transmission oil level and it was not showing any on the dipstick! He has had the bike 2 months and told me he was going back to his suppling dealer this week...hope you work something out buddy...

    Anyone who has an M8 with hydraulic clutch (therefore NOT Softails) PLEASE CHECK YOUR TRANSMISSION OIL LEVEL
    TomG received this email from the guy I mentioned. He had 60-70% of his tranny oil migrate!

    “This is really to say thank you to a guy i met at the international rally i believe he goes by the name of ulysses on here took my bike back to cheltenham hd they have drained the oil from both primary and tranny not much left in there 60 to 70% migrated they have refilled both to correct level told to come back after 1000 miles have told the manager that if it happens again which i am sure it will if they cant 100% fix it they can have the bike back. any way again thank you .will let you know of any developments

    Regards

    Alan Smith”

    Therefore THERE IS STILL NO FIX.

    Stick with a good old twin cam.
    All problems are ironed out now.
    And cheaper than a shovel too.

    On return home from the International (181 miles) I thought its time to check the oil level on the gearbox on my 2017 Street glide Special . And yep no oil on the Dipstick. Bollox try again and no it wasn't lying. Phone call to HD Leeds and i added 350 millilitres of oil to bring it up to the top level mark.
    Last weekend run to the Farmyard followed by trip to Leeds for the 5000 mile service and stage one.
    The dealer put more oil in , and when the primary was opened it poured out.
    Apparently there is now a fix and the new part is on order and as soon as it arrives i have to return to get it fitted.

    Fingers crossed we will have this problem solved.

    How do Glen I thought it was happening to my CVO street Glide ive covered 700 miles since my shock horror no oil on the dip stick moment and since then the oil level aint moved and I give the CVO plenty of right hand every day on the way to work so fingers crossed still but keep us informed on the part for the up grade to hopefully cure this fault

    If this is the ‘Transmission Oil Deflector Kit 36300028’ (a plastic cap) then there is a lot of evidence on various forums that it does NOT work. I started a seperate thread in this M8 section on it. My dealership installed it without my permission to my bike and I have refused to collect the bike unless they guarantee it works...they cannot.

    There’s certainly a lot of TC’s for sale out there, at good prices too...

    But c’mon, the Evo is the one to have!
