That's great feedback and pleased you like the Tokyo Offroad Oil Drain Tool. Yes, when I used the oil level screw to set the oil level it made a huge mess over the cases, frame, skid plate, stand and mat. Definitely something I wouldn't want to do for each oil change, not to mention the risk of stripping the case threads.

Thanks for the confirmation regarding your 2020. I wouldn’t expect the 2020/2021 to be any different as the bottom end design hasn’t changed. Always good to confirm through measurement though...

I'm pleased you like the drain tool...

Yes, the oil level screw case thread is quite easily damaged. One of my riding buddies has stripped his. Regarding the oil level setting method, I believe the method I showed in the video is correct, remove the screw and wait until it stops overflowing. If it's not overflowing add more oil...

I always drain the transmission oil with my bike on the side stand, leaning over to the left. The garage floor is level laterally and slopes slightly towards the front of the garage (to allow water to drain). Therefore the engine is tilted to the left (due the side stand) and to the rear (due to the slightly sloping garage floor). I previously tried tipping the bike over to the left further to see how much additional oil would come out, but only a very small amount came out so I don't bother to do that.

Dont butcher it with different bolts everywhere. It'll be like $2 just get the factory one and keep it nice. Also if you're running the stock levers and it fell off when you lost the bolt then youll need the return spring aswel

I use Amsoil and have great clutch feel and smooth shifting. As far as price goes, I don’t understand why people worry about minimal extra cost per oil change in a $10,000 (USD) machine.

No. I think you’ll get slightly more clutch drag when the oil is cold and spend a bit more on oil. Slight weight difference too.

Yes, there will always be some oil left inside when you do your oil changes. When I did the measurement I drained the oil the same way as I always do (on the side stand) so I know how much fresh oil I need to add to bring it up to the correct level, without using the oil level screw.

Serhii Khachko - Assuming you drained the old oil, putting in 800ml should be fine. It does bring the oil level up a little above the oil level check bolt, but many people use 800ml and I haven’t heard of any issues. I think your leak is due to something else. When you changed the countershaft seal did you replace the o-ring and the sprocket washer too? Also check your chain slack is within speck. Too little slack can cause leaks at the counter shaft.

Thanks for your interest. This version of the ODT will fit your 2016 TC250 (oil drain on right side): www.tokyooffroad.com/product/standard-oil-drain-tool-odt-kit/

The 2013 500EXC I had required 1.5L too. On that there was a sight glass on the engine case so you could easily confirm the level was set correctly. There was no oil level bolt check.

@@TokyoOffroad is it 675ml for the 2017 300 carb exc as well?

Yes, but make sure the bike is level. I don't recommend using the oil level check routinely as it's easy to strip out the thread (I know several people who have stripped it). I find it much easier to measure the amount of oil required once (as shown in the video) and just added measured amount each time the oil is changed.

I purchased mine in a local motorcycle parts and accessory shop in Tokyo. Volume is 1000ml

I'm wondering the same thing, I feel that the engines are the same regardless of fuel injection or carb. Have you tried using 675ml with your carbed bike or continued using 800?

I think there are two negatives: 1) You'll get slightly more clutch drag, particularly when the engine is cold; 2) You'll spend more on oil.

No, I don't think it's that bad to have a small amount of extra oil. I personally don't think there is a major issue in adding 800ml, other than a marginal increase in clutch drag and you'd be spending a little more on oil. And as someone else mentioned it would weigh a little more, but 125g this low down on the bike would not be noticeable. My motivation for this exercise was to accurately measure the amount of oil being drained out from when the oil level is set correctly, so I can add the right amount of oil without having to use the messy oil level check bolt method. But as they say, there are many ways to skin a cat, so it's perfectly fine to use the oil level check bolt, just be very careful not to strip the case threads like some others have.

Im going with the theory that the oil drain screw is the minimum amount of oil.....125cc of oil is 8 table spoons no big deal spread over the width of the engind. Can somone point me to the referance in the manual that says 800cc on a rebuild, cause I sure cant find it either in the owners manual or the service manual. the only number is 800

Yes, they should all be the same

Needed to do an oil change just after this came out. Sure enough, my '18 TE250 took 660 to start coming out the level hole.

Thanks. Yes, in general people seem to prefer the new intro video. But I know there are probably one, or two die hard fans of the old intro out there ;-) I use Motorex Top Speed 15W50 oil for the transmission.

I don't have any problem with the old intro, it's just seems people wants something fresh and because mankind doesn't have too much patience anymore these days... \= PS - It seems like you have some mind reading power, since almost every time I have a doubt or question about something related to my bike, few days later you have a detailed video on it haha.

I've been meaning to make a new intro for a while. Then someone's critical comment about 2 weeks ago and also achieving 10k subscribers to the channel, pushed me over the edge and inspired me to make a new one. I outsourced the intro logo animation to my son as he boasted that he could make a much better intro than me. He was right and did a good job... I can't read your mind, but I do work on my own bikes and some of my riding buddies' bikes, so run into the same, or similar issues and challenges as you and others. And certainly if something isn't clear in the service manual putting together a video to clarify can be very useful I feel...

Your son has some skills :) I think the music at the end of the intro should last another second so the fade-out effect can me more refined and without a sudden stop (just my opinion)

Nir Hason Agreed. Will update it for the next video...

What bike do you have? Unless you have a good reason not to my recommendation would be to use the oil specified in your owners manual. For late model KTM 2-strokes 15W50 oil is specified and Motorex TopSpeed 15W50 is stated as the recommended oil.

@@TokyoOffroad husqvarna TE250 2015 with 76hrs on it

@@TokyoOffroad at the moment am running it on Silkolene Light Gearbox Oil

The Enduro Rider - I use the oil specified in the manual (Motorex Top Speed 15W/50. Not sure what you mean by effects. If you’re referring to the effect of oil volume, the main one is increased clutch drag with higher volume, especially when the oil is cold.

Typically 2-strokes don't burn transmission oil (unless the crankshaft seals go) so the oil level stays very constant and it not necessary to monitor the level between changes. 4-strokes can burn oil during use and as such the level will go down over time and a window is useful for monitoring that.

Tokyo Offroad well I guess it’s something for there design team to figure out. I have a vintage 2 stroke with a window and on the filler cap says.700 ml on it. If a 27 year old design has it why not a new fuel injector bike design skip out.

“Oil check BOLT” not hold

I don't think using 800ml of oil in the transmission is a big issue. The only negative points I can think of are you'll get slightly more clutch drag (particularly when cold) and spend more on oil. But going forward I will be using 675ml for each oil change as it seems to be the optimal amount based on my measurement.

Tokyo Offroad I agree, I will do the same, I don’t even have an hour on the bike yet.. gonna do the change at the 5hr interval like the owners manual says... I’m waiting for the oil drain tube that I ordered from Slavens Racing to keep it clean

Yup, oil changes are cheap, quick and easy (especially with a Tokyo Offroad Oil Drain Tool ;-) ) on these bikes and if you do it regularly the transmission will last a long, long time...

Tokyo Offroad haha 675 is the magic number... just did my oil change for the first time, and out of curiosity I pulled the oil check bolt, and I poured in 600ml at first, and then 25ml intervals and shortly the third one it started to seep out!!! 675ml it is... also I let it drain very well, even added more lean then what the kick stand offers...

W in the oil (ie 80w) does not stand for weight,

Paul Jerse , right, it the cold weather viscosity. When I say a heavier weight oil I mean like a 20w-50. I don't like the 0w-20 oils like my Toyota requires. But I think 80w might be a bit much. Sometimes I use strait 30.

3/4 of a quart is equal to 710ml which is very close to the 675ml I measured. I use Motorex Top Speed 15W50 which is the recommended oil for these bikes. I've never had any clutch slippage issue and get good life out of the plates. How long have you been riding? I'm hoping I'll be able to continue off-road riding for a long, long time. So much fun...

Tokyo Offroad , I've been riding 48 years now. I'm 56 and ride a 200 and 350 exc. We ride the absolute hardest terrain out here on the Ramapo mountains of NY, all rock and steep inclines. Our bike get nothing but abuse and we ride at least twice a week without fail unless the snow is too deep. My friends I ride with are all about the same age, some of them are fading fast but a couple of us are die hards. Keep up the riding, watch the videos. How old are you, what do you ride? Where?

I'll be 53 next month and have been riding off-road motorcycles for just over 40 years. I currently have a 2017 250 EXC modified with a Keihin PWK 38mm Air Striker + STIC metering block and a 2019 250 EXC TPI. I ride in the mountains in Japan every weekend, year round, with a group of buddies. I'm positive that riding keeps you young, especially the mind. Wish you many more years of riding...

Robson Enduro - Yes, that’s correct. The issue is that it’s time consuming doing it that way every time and also creates a lot of mess. The bike needs to be perfectly level for it to be accurate. Also the oil check bolt size is small (M6) and torque spec relatively high at 10Nm. It’s quite easy to strip the case thread when installing the bolt and I know several people who have stripped the threads. As such I prefer to measure out the oil and not use the oil level check bolt.

I made another video for my 2021 300 TPI which takes a little more oil (I measured 720ml) than the 2017~19 models as the engine is rotated a little forward in the frame. The 2020 is the same as the 2021 regarding oil volume: kzfaq.info/get/bejne/m76lotmCrNLGiX0.html

I think you mean 0.8L or 800 milliliters.

chris marshall - That’s interesting, although I haven’t seen any change, or had any issues running 675ml of gear box oil in my bikes.

Tokyo Offroad I didn’t think it would have caused an issue but the oil Was burnt to a crisp. Was stinking. We were riding tight woods and river beds. A lot of clutch slipping but nothing we don’t normally do.

It sounds like something is wrong. Are you sure your clutch isn’t slipping. Or maybe something got stuck in your chain, sprocket. Setting the oil level using the oil level bolt is a common method and results in the same volume of oil. I’m sure the oil volume isn’t causing the issue you’re seeing.

Tokyo Offroad everything seems fine. It was perfect the week before. Only thing new was less oil. I will see how it fairs next outing with the only easier added. And go from there. I also fitted some v force 4 reeds but that couldn’t have caused any related issue. Bike runs a lot crisper down low now.

@@chrismarshall4814 I want to second your initial statement! I also used 675 ml in my previous oil change and had problems with the clutch. I dropped the oil after the ride and it was all burned and smelly (as clutch residue smelly). We ride really hard trails, where the clutch gets abused a lot, but I never experienced any clutch related problems until now. My understanding is that extra ml of oil up until 800 ml will protect the clutch from overheating in severe conditions. I never had this problem before, we ride the same trails, the only thing new was the 675ml of oil, too little in my opinion. I put 800 ml immediately afterwards and I returned the next weekend to do the same uphills. The problem disappeared.

The oil dump is the same method I use every time when I drain the oil. I install the oil drain tool and with the bike on the side stand drain the oil. What came out was 675ml. If I put 675ml of fresh oil back in the bike the level will be at the level of the level check bolt. If I put 800ml in it will be above the level of the oil level check bolt.

Regarding the color of the oil, this was the second oil change from new. I'm expecting future oil changes will be much clearer.

whats ur thoughts of how i get every last drop , by taking thr plug out and gently by hand engage the kicker

That is true. Although I'd always err on the side caution and ensure that the transmission and clutch longevity is not impacted, rather than trying to save weight low in the bike.

just carry 125cc less water.....

@@billdrisc217 And my "less oil" idea sounded bad...
