    i would have expected some engine oil consumption with a continuously loaded engine rather than trans oil.i would imagine for oil loss in a small trans due to heat it would have to get damm hot, and possibly leading to component failure due to break down of the oil at that heat and probably expect some oil mist from the trans breather.does the oil smell cooked or change color ?.

    Kia Ora.
    The oil breather is dry and I have put in 1-200ml over when heading on long trips but still no sign of oil.
    As to the colour of the Trans oil I change it frequently, usually to confirm volume and or because theirs a new oil to try, however.
    The oil will be dirty, but there always seems to be colour.... but don't forget that I'm always adding oil so I don't think it gets a chance to loose it color.  Put it this way, I kept the quart bottle that I extracted to reuse if caught in a bind, it was looking that good.
    No burnt oder that I have smelt.

    It's hard labour that show the oil loss, short easy rides there is no significant loss.

    You sure youre not overfilling the gearbox?  You say you change the oil regularly, what is the least amount that you have saw run out of it? I had an oil leak one time and only a dribble came out, has that happened to you?

    The dipstick in my gearbox can be hard to read cos its that plastic chrome stuff and you have to be extra vigilant to get an accurate reading.
    How do you check the dipstick? Screw in or just touch the thread on the gearbox? I just touch it on the gearbox.
    I dont know how old you are but my eyes arent as good as they used to be. Maybe get somebody with good eyes to have a look.
    Oil doesnt just boil away unless its red hot and then it stinks. Who fitted the side car? They didnt bolt it directly to the gearbox?

    Interesting question around Volume, it hard to get a figure from Harley, but as I understand it a Quart, just under a liter is required.
    When I test after adding a quart, I get a full reading, and yes my eyes are getting past their used by date, but I have been diligent in checking the oil in the same manner and with good light etc you can always recheck to be sure what the eyes are telling you is real.

    You say that you don't thread the dip stick in to check.
    I do, and I reckon if I didn't I would be using near 2 liters to register as full.

    I have said earlier that I have over filled it, perhaps by as much as 200ml, still no blow by from the breather.

    And no the sidecar is not connected to the gear box in any way.

    When you drain it how much oil comes out?

    usually less than a Quart.

    That sounds  about  right. 
    Its supposed to take around  750 mls to fill. If you're  getting  roughly that back out I would suggest that you don't have a problem. 
    The mutt looks guilty of something but maybe he didn't drink the gear oil after all.

    sorry I can't help with your leaky g/box but I know where to get the Redline shockproof Heavy gear oil from, BNT auto spares sells it here in NZ it's good stuff and its bright red which may help to detect a leak
