gear oil change on 125cc motorbike

[mark214]

hi guys has any1 got some pics or a video of how to do a gear oil change on a hongdou urban dz 125.

i do no my way around a bike but have never done a gear oil change and am just unsure on a chinese bike.
do i need a new oil plug seal or anything like that also whats a good gear oil 2 use on this bike

Is that a 2 or 4 stroke?

The oil change must be the same as any other engine put there. Unscrew plug -> Drain old oil - > Change filter (or clean mesh if there is no filter) -> Screw back plug -> Put oil in -> Check level.

Any 15-40W or better 20-50W WITHOUT additives is OK. Go for the cheaper ones with API SJ or SF. SL usually have lot's of anti-slippage additives that are not good for the clutch. That's if your bike has a clutch at all

It's a 4 stroke. I have done the engine oil change. But never done the gear oil change it's a 125cc manual clutch and gear. I was told there is 2 screws 2 open but where r they?
