Oil change today

So, since I'm going to be putting my Tenere away for the winter soon, I began to change the oil.
Usually the engine is warmed up as normally I do oil changes with a warm crankcase.
However; today, I chose to change the oil with a completely cold engine. I removed the forward oil drain plug and observed very little oil drain, perhaps only a half litre (quart). I put the drain plug in and tightened it sufficiently as tomorrow morning with my garage door open, I will let the bike run for about 3 to 4 minutes, shut down and try to drain the oil. I haven't removed the rear drain plug yet.
What am I missing? Or does the cold oil collect somewhere in the engine where it will not drain?
I rode the bike yesterday and when I got home I put the bike on the centre stand and had a look at the oil level and it was full.

Super Teneres have a dry sump oiling system. There are 2 drain plugs. You found the crankcase drain and there is another one for the sump behind it towards the back of the bike. That's where the rest of the oil is.

Ah, as I recall when doing previous oil changes a considerable amount of oil came out of the forward drain.
The engine is still cold, so I will remove the rear drain plug and see what comes out.
Thanks for assistance magic.

Magic beat me to it.

Being a 'dry' sump system, the oil pump actually does 2 jobs. The second job is to scavenge the crankcase of oil and push it to the tank.
The forward drain plug is to dump what remaining oil that has not been scavenged, and the rear plug is the oil tank.
Depending on conditions, there could be more or less oil that comes out of the forward plug.
Or, you used a lot of oil :eek:

Here's a picture.

Just did mine the other day. Pulled the front drain plug, and then the back. Like you, only a small amount came out of the front. The rest came out of the back; and it was a lot.

Edit: there's also some oil in the filter, if you're going to change it too.

If you run the engine till the fan comes on and then immediately pull the front drain, you get a lot more. I just did this today.

Its all the same, since it would have just drained from the other plug anyway.

Remember there is like 4.2L of oil but you only drain 3.4l per change.

I finished my oil change this evening.
I drained the oil from the rear drain plug and yes, that is where the majority of the oil comes from.
In addition, I changed the oil filter along with the "pumpkin" fluid.
Just need to give her a good wash and off to the storage shed until late March or likely April barring any suitable riding days. I'm always hopeful for a day or two of riding in the winter season. Provided the roads are clear of ice and snow and a temperature of 6C or 40F or higher I will ride.
Thanks to those who were kind enough to chime in with advice about my question about the oil change.
I'm using Motul 5100 semi syn 10W40.

With the bike level on the centre stand, I pour just shy of 4 litres into the bike.
Tomorrow morning I will open the garage door and let the bike run for 3 or 4 minutes.
Shut it down and wait maybe 10 minutes and then have a look at the site glass. I'll likely have to add additional oil as the oil filter will fill up.

Yup, gravity always wins.
Although it's best to change your oil on a warm engine, one can also do it on a cold engine provided you are patient and give the oil adequate time to fully drain.

4 liters is too much. It is written everywhere .... 3.1 liters without changing filter, 3.4 liters, also changing the filter ...... and 4.2 liters for assembly

First time when I saw the Yamaha manual recommend every other change. It's still $15 bucks so it might make the difference. They take the super safe route. So getting another filter even at $7.50 might matter. Also after taking a few automotive classes the instructor pointed out they best thing you can do for your vehicle is change the oil more then what manufacturer recommends.

Hi to all!
What is the advantages of 'dry' sump system ?
I have heard that some engines do have this system, but will appreciate if someone can explain the advantages/benefits of the system.
Regards.

I'm using Motul 5100 semi syn 10W40.

Don’t Yamaha recommend fully synthetic? It’s all I would use, especially on a keeper

Fully or semi are fine as long as they meet the required specifications. I’ve used Yamalube Semi Synthetic from when I got the bike at 3k miles, to the current 35k miles.

I’m very likely to go over to fully synthetic after I’ve used my last lot of semi. I’m only doing this out of curiosity really though, want to see if it smooths out the gear changes or feels/sounds any different. Nowt wrong with what I’m currently using, just want to see if there’s a difference.

Basically, the main function of the dry sump in the S10 is to be able to place the engine as low as possible (to lower the center of gravity), without reducing the free space to the ground. Some motorcycles use their own chassis as the oil sump.
Other uses are more related to race cars, where you want the engine to be as “close to the ground as possible”, and due to inertia, in turns or acceleration, it is necessary to avoid it (oil movement) ... and it is better to have it in a reservoir separate from the engine.
