How to drain gear oil?

[bunker buster]

So I reach the 3000 km mark. How do I replace the gear oil since the bolt are sideways. Do you guy use compress air to blow out the remaining oil? According to the manual I should not mix gear oil of different brand.

I do not have the bike you have BUT I think most of them are similar: horizontal bolt for fill and a vertical bolt on the bottom for drain. Pull both out and drain preferably after gear box has been warmed up by riding. The drain cup will catch most of the thick gear oil after a few minutes. Put the drain bolt back in then put the required amount of gear oil specified in the fill hole WHICH WILL GENERALLY NOT COME UP TO THE BOLT HOLE. I belabor this since I overfilled mine the first time!

I dont have a manual, so i am not sure of how many ml of gear oil to put in.

GV take's 180 ml of gear oil..  use a syringe to add and you can't miss.   https://www.amsoil.com/shop/by-product/gear-lube/severe-gear-75w-90/

Don't change the gear oil unless you are willing to download the manual which cost nothing.  Guessing introduce a problem where the was no problem to begin with. 

There are  ONLY two reason to change the gear oil:
1. verify the condition - no contamination, some but not an excessive amount of metal shavings.
2. quantity - there is no dipstick and if it is "low" you might have a leak.  In time, if it leaks out the diff will burn up.  Otherwise gear oil does not get dirty or ever wear out in this application. 

Any brand will do.  Don't waste money on synthetic.  I use supertech from walmart.  I have gone from 2600 mi to 20K miles and my scoot runs perfect.  Many owners take stuff apart without the manual or proper knowlege and tools and introduce problems in something that was working perfect.
