    Oil consumption on my Honda Dominator

    Hello there folks! Great forum you've got here.



    Newbie here, Joško from Croatia and i have a question about my 1998. rd 08 Dommie.

    Recently i've changed the oil after the 3000 km interval and it really struck me to find that i've only draind 0.9l of oil from it.

    Can anyone tell me what's the normal oil consumption for this bike?

    The bike has about 72000 km on it. And im using Motul 5100 15w50

    Thanks in advance!!

    Which drain bolt did you use? there are two. One in the down tube between the headers just before it splits into the bottom double cradle.
    and one on the LHS of the engine just behind the gearchange lever.
    These engines will tend to use a lot of oil if run at high speeds >100kph for long periods of time.

    The longer I hang around the more use I become

    Here is the frame drain and then the bottom mesh filter position. I am about to do a post about this mesh filter in a moment. I have only checked the mesh twice since owning the bike.





    Here is the engine drain plug

    Yes i've drained both of them.

    The bike is my daily commuter. And i make a minimum of 50 km daily (just going to work and back),and yes, my traveling speed is about 100 or 110 km/h everyday. Could this be the reason for that kind of oil consumption?

    Could be a number of things, Valve stem oil seals, easy enough fix. Worn rings not so cheap/easy.

    More to the point, do you not check the oil level every ride?
    Leaving it until there's only 0.9l left, you were very lucky you didn't trash the engine.
    At the sort of mileage on your engine you can expect some oil consumption. It will be a combination of stem seals and ring wear. The ring wear will burn oil but also allow a little blow-by which may well be pumping oil out of the crankcases.
    If the bike starts easily, runs well, ticks over when hot and doesn't smoke then just keep running it - but for Pete's sake check your oil level - every ride!

    I dont quite understand this. What do you mean by saying "Ticks over when hot"? You mean "if it runs well when hot?" Or something else?
    Thx

    Tick over is another way of saying idling.
    Ticking over = Idling.

    Aha, i see,thanks. Btw, could you tell me how much slack shoud be on the drivechain? I've changed it yesterday,and i've adjusted the chain tension while the bike was on a central stand,so that it was adjusted to around 35mm of slack. But driving it seems like it's loose a little bit because when i'm riding it and when i twist or release the throttle i can feel the drive chan punching a little and it seems like it's pulled up above the 35mm..
