 Hey guys, today I'm going to show you how to do a simple transmission oil change on a gas gas EC300 from 2011. One of the best things that the two strokes have is the best and quickest and simplest maintenance that you have to do on these bikes. Since the bike doesn't have many moving parts, you don't have many things to worry about. And one of the only things that you have to do is regularly check and change the transmission oil. And it's actually a really simple step to do it as well. The only thing you'll need is a six allen key, somewhere to put the oil that you use well, and in my case, an 80-90 oil. This is completely dependable on the type of use that you give to the bike. In my case, I use it a lot on hardened roads, so I use the clutch a lot. And it's a good thing to use the highest capacity oil because in hardened roads, the clutch tends to heat up really fast. So if you use the highest capacity oil, it will keep the gears and the clutch a lot well preserved. Then if you would use a 10-50 oil, for example. But if you ride straight away, classic in the room, no problem whatsoever using that kind of oil. It only depends on the type of use that you give to the bike. Before doing this oil change, you should run the bike for about five minutes just to make the oil a bit more flowy. So it's easier and quicker to do the oil change. The first step, remove this bolt and then remove the train bolt. What they have on their train bolt is a magnetic tip. And this is really good because you can have a small glimpse of the shape of your transmission just by doing an oil change. Because you can see how much little pieces of metal gets stuck on the magnetic tip. As you can see, in my case you can see some really small bits. It's normal to have some small bits. Obviously that if you see some big chunks of metal, you should definitely open it and see the shape of it. To make sure you remove all the oil, clean the bike on one side and the other just to make sure that you remove everything. Clean the train bolt when you don't see any oil coming out anymore. Tighten the train bolt again in this place and tighten it well. It's really important so you don't have any more leaks. Last step, put in 900mm of oil. I strongly recommend you use a funnel because it's really inaccessible to put the oil just through the bottle. It's pretty much impossible without making a huge mess. So a small funnel and you have a thing to sort out. Before starting the bike, you should always turn the kicks a few times so the oil gets spread out evenly on the whole transmission. And only then you can actually start the bike. That's all. Hope you liked it. Subscribe and anything. Comments below and I'll answer you whenever I can.
