Yamaha MT-03 660cc: how to change oil + oil filter

[@jobvangils120]

Zelfs in 2024, met mijn pas gekochte mt03 deze handleiding nog kunnen volgen. Bedankt voor de video!!

[@Noke28]

Just changed my oil 2 days ago thanks to your video. No leakage and I also used the Procycle Oil Thanks!

[@MotoSnax]

Great! Glad my video helped.

[@MisterstereoOso]

Just bought a 2006 MT 03, thanks for this great video to get me started on my spannering journey 😊🇬🇧👍

[@tristank1993]

Net in het bezit van een MT-03 als eerste motor. Dit gaat goed van pas komen, thanks voor de video!

[@MotoSnax]

+Tristan Kerseboom Graag gedaan. Veel plezier met je MT-03!

[@miniheckler]

Hi thanks for the video, great stuff. I had changed my oil prior to watching your video and only drained the plug underneath the bike, not the side one for the gear box, nor did I release the oil pressure... I also noticed that trying to squeeze 3 litres of oil in just made it overflow, but I suppose if I had not drained the gear box that would account for a further litre or so? Thanks again. I'll go and do it properly this time! Ally.

[@MotoSnax]

Thanks for watching. If you follow all the steps 3 liters would fit. Don't forget to start the bike and use the throttle 5-6 times after adding 2 liters of fuel. You don't release oil pressure, you want the air to get out. If there is too much oil in the engine it will send it towards the air filter housing. The oil filter part does not contain that much oil.

[@miniheckler]

@@MotoSnax Hi. Thanks for getting back to me. Hopefully get to it tomorrow. Thanks again. 👍

[@NinoCotonato]

Thank You!!! As you know, the oil caps have the oring? mine not and lose oil

[@MotoSnax]

It probably has one. I sold my MT-03 about 10 years ago, so I cannot check. But it would not surprise me if it has an o-ring. The Yamaha dealership can help you with it.

[@chris_auernhammer]

Yep i put too much oil in it when I did my first oil change with the mt... :D I was like maaaan the manual is wrong the oil level isn‘t even close to the correct level... 150 km after that i noticed some oil leaking out of the top screw 😬 Then I removed some oil again. At least it‘s not that big of a deal if u put too much in a dry sump engine but nontheless good that u mention it and prevent some people from making the same mistake as me! :)

[@MotoSnax]

When I purchased the bike at a dealership (not Yamaha, but a Kawasaki dealership) I specifically told them how to chainge the oil. Guess what, they did not listen. The oil was pushed towards the airfilter box. That was a big mess inside the box. Had to clean that up and take about half a liter of oil out of the reservoir. The mechanic probably never had experience with dry sump engines and was too lazy to read the manual.

[@peteguru9741]

Super. Amazing guide. Thanks !!!

[@benascereska6968]

Hello, Internet says to add 2.4liter in video it says to add 3liters. When I added 2.4liters and let the bike run for few mins it shows low on oil. Should I add 600ml more? Thank you for your answer in advance

[@MotoSnax]

I don't know why the internet says 2.4 liters. It is 3.0 liters without filter change. My info is straight from the manual itself. I also checked it for the 321cc version but then it is 1.8 liters. For the XT660X is it 2.5 liters without oil filter. Still no 2.4 liters... so I don't know who mentioned it, but that is wrong. It is 3 liters like in the video.

[@thespecialone2263]

Lovely video. Thanks mate!

[@frosticky]

Bedankt voor de video! Weet je toevallig de diameter van de o-ring die je vervangt op 2:21? Ik kan nergens op het internet de afmeting vinden :(

[@MotoSnax]

Graag gedaan! De maat weet ik niet, artikelnummer moet 9321064X0100 zijn. Zoek op Google even op 'Yamaha O-RING 9321064X0100' en dan zie je diverse webshops. Ze kosten zo rond de 3,50-4,00 eur.

[@frosticky]

@@MotoSnaxJe bent een held! Bedankt !!

[@Noke28]

Hey! I want to change the oil and oil filter on my Mt 03 in the next few days. I forgot to order the copper rings for the drain bolts and also I didnt order any rubber rings. I wouldn't want to spend an extra 5 Euro for shipping on Louis to get them. Do you think I can do this Oil cahnge without replaying any Copper Rings or Rubber bands? the last oil change was 5 months ago at a Yamaha Dealer. Kind regards

[@MotoSnax]

Best is to replace both but if they have been replaced about 5 months ago you can give it a shot. Worst thing that can happen is that you will have minor oil leakage. Just check it a few times after changing if it is dripping oil. It it does not leak you are OK. Not everyone replaces them each oil change but if you want the perfect oil change you will need to change the washer too. :)

[@Noke28]

@@MotoSnax thanks a bunch! I'll try my luck! When I'll change the oil next season, I'll be proper and replace everything!

[@caroule9137]

Wonderful ! Thanks for sharing ! I'm doing mine this week-end

[@MotoSnax]

No problem. As for the MT-03 it is a little bit different than normal, I decided to film it. Always useful.

[@TriggerBrky]

Is castrol 10w/40 is suitable for my mt-03 660

[@MotoSnax]

If it is Castrol for motorcycles, yes. If it is for cars, no. Castrol POWER RS 4T 10W-40 would be the one that works.

[@mptful]

Hi there - This is a really helpful video. thanks! Can you tell me what is the size of copper washers on the drain bolts?

[@MotoSnax]

I ordered them at a German webshop, orderd size 14x18x1,5. You have two drain bolts, so you'll need two. :) Otherwise just order them at your local Yamaha dealership.

[@soetowidjojodonovan9540]

Heel leerrijk danke voor de video Heb nog een vraag ik heb 3.1l gevuld maar de dipstick wijst nog steeds weinig. Heb ik iets gemist

[@MotoSnax]

Nee, een dry sump peilen is gewoon erg lastig. Je moet 'm eigenlijk eerst een kwartier lang rechtop zetten en laten draaien (of een stuk rijden) en dan moet je peilen. In de handleiding staat hoe het moet. Wat ik altijd deed was kijken of er olie op de stok zat en zo ja, dan vond ik het best. Ik koop nooit meer dry sump, ik wil direct via een kijkglas zien wat de status is.

[@ekagilberto]

Hi there, thx for sharing this video, So for the total oil that you add was 3 ltr? 2ltr first then start up then add another 1 / 1.1ltr? Sorry, just want to clear up my confusion after watched the video. Thx in advance

[@MotoSnax]

Yep at 3:37 first add 2 liters. Close oil cap, start engine, rev 5-6 times. Shut down engine, open oil cap, add 1 liter. In total 3 liters. Because it is a dry sump system you need to do this in two parts.

[@ekagilberto]

Thank’s , by the way how long ( mileage )for the bike each time changing the oil and oil filter? Cheers !

[@MotoSnax]

10.000 kilometers.

[@alessandro8968]

HI! Thank you for your great video, where can i find the copper washers for the drain bolts? Thank you :)

[@MotoSnax]

The Yamaha dealership? I think I bought them at Louis Motorrad, which is a German webshop.

[@Piomeks]

PERFECT thank you i'm gonna change my oil :)

[@MotoSnax]

No problem, glad I could help.

[@vinsanity8285]

Great video! Very helpful. But how often do you have to change oil on the mt03?

[@MotoSnax]

+Vincent Lundh Thanks. Every 10.000km (6250 miles) or at least once each year. Which ever comes first. Usually I do it before I store the bike for the winter (I don't make 10.000km per year on the MT-03 because I ride on many bikes).

[@jonebm]

I've had my MT-03 for two years, but I've only ridden 4000km. Therefore, I have not changed oil nor filter. It is my first bike, so I am accordingly noobish. I realize now that I should get right out there and change them both, which I will (thanks for helpful vid). But what are the downsides of NOT changing oil (and filter) every year, even if you do not ride very much? Thank you in advance.

[@MotoSnax]

Oil will get dirty even if the filter will filter out most dirt, it will clog at some point, letting dirty oil pass the filter. Also additives to oil will wear out so it won't lubricate as it should. Next to that oil is hygroscopic, so it will 'attract' water/moisture, so water will also be in the oil, giving less lubrication. No worries yet in your case, but after two years it would be nice to swap the oil and filter.

[@jonebm]

Thank you! :D

[@iLwSZ]

Any clue on the sizes of the gaskets for the oil filter and the washers?

[@MotoSnax]

I purchased the o-rings for the oil filter at the Yamaha dealership, did not measure the size. For the washers the same.. sorry.

[@iLwSZ]

@@MotoSnax Yea that's fine, I just don't have that option, that's the thing, I was more curious about the oil gaskets

[@MotoSnax]

Can't you contact one and let them ship by mail? I've sold my MT-03 years ago...

[@iLwSZ]

@@MotoSnax I think I've found the right copper washers, but no hope on the o-rings anywhere

Maybe this helps with part numbers in your search: large o-ring www.cmsnl.com/yamaha-mt03-2007-5yk4-europe-1f5yk-351f1_model45640/o-ring_9321064x01/ red o-ring www.cmsnl.com/yamaha-mt03-2007-5yk4-europe-1f5yk-351f1_model45640/o-ring_9321007x01/ Not 100% sure about the big o-ring though......

[@dvdmcd]

I stoped to put 3.0L on my MT 03 660. Nowadays I put only 2.8 L. The oil on the balance and the excess of oil on the air-filter never more appeared. I think that the Yamaha make a mistake to recommend 3.0 or 3.1 L for this bike. For the XT 660R, with the same motor, the recommendation is 2.6L.

[@MotoSnax]

2.8 L is fine too. There is no mistake in the manual. The XT660 has got the oil reservoir inside the frame. the MT-03 has a separate oil tank in front of the engine. That is why the XT needs 2.6L.

[@AnEngineerInEurope]

Any experience on what oil the mt likes/ dont like? I'm not sure if i should buy 5w40, 10w40 or 10w50.

[@MotoSnax]

Yamaha recommends 10w40 oil, but it probably also depends on where you live. I bought a cheap brand motorcycle oil and it worked well with it. This engine isn't that demanding like supersport bikes with a lot of power.

[@fotografnamotorce6786]

Thank you so much! I was looking for a video exactly like this one! But I still need to ask you for help, if I don't buy those rings from a local yamaha store, how can I know the size of those rings? It's not even written in a manual. :(

[@MotoSnax]

Do you mean the oil rings or the washers? I don't know the size of the oil rings, why don't you order them at your local Yamaha store?

[@ikidoksandokuz1595]

Does the oil have to be a 4t-oil? Or if is 10w40 (gasoline engine) oil OK?

[@MotoSnax]

Make sure it is motorcycle oil, for four stroke motorcycle engines. Car oil is different. I would only use car oil if the oil level of the engine is so low that you'd wreck it if you didn't add anything to it to lubricate. But then I'd replace it as soon as possible for motorcycle oil.

[@gbner9991]

hello what is the tire in the video?

[@MotoSnax]

Michelin Pilot Road 4.

[@gbner9991]

@@MotoSnax thank you i bought a mt 03 and it has theses tires. i hope i get to ride it soon. are they good?

I liked the tires, also good on wet roads.

[@jacopochiefjaco123]

Hi! when do you purchase the new o-rings and coppers?

[@MotoSnax]

+wjung coppers each oil change, o-rings can wait a little longer. If they start leaking you know what to do. :)

[@jacopochiefjaco123]

Thank you very much :) Meanwhile I asked my mechanic and he answered the same. Thanks again!

[@ikidoksandokuz1595]

Hey, what does those o-rings and copper washers cost in the Yamaha store?

[@MotoSnax]

Price will differ per country and per dealer, but it will be not much money.

[@RodrigooMMartins]

why did you replace the original washers with copper ones ?

[@MotoSnax]

As a precaution. If it gets too old or worn, it can cause oil leakage. They cost nearly nothing, so I always replace them when changing oil.

[@dwano10]

Vraagje hoe groot zijn allle o ringetjes die je vervangt en hoe heten ze ?

[@MotoSnax]

Ik heb de MT-03 al even niet meer. Beste kan je gewoon naar een Yamaha-dealer gaan en vragen om beide o-ringen. Hij kan ze leveren voor een paar euro. De gewone ringetjes ('washers') voor de bouten, kan de Yamaha-dealer je ook zo leveren.

[@reeto8514]

Good video thanks

[@MotoSnax]

[@robvantilburg5420]

Zeer handig deze video!

[@MotoSnax]

+Rob van Tilburg Altijd handig en niet moeilijk om zelf te doen. Nu alleen nog zien hoe de goedkopere Procycle olie het gaat doen, maar op Motor-Forum zijn ze er positief over en de MT-03 is geen pk-monster.

[@Hurryupoldbird]

Thanks mate for great video

[@lukasanonym7621]

Thanks! What oil did you use? :)

[@MotoSnax]

Procycle. It is a private label brand from Louis Motorrad. As the engine is not that powerful I wanted to try that. It is not a racing machine needing the most expensive oils in the world.

[@MotoSnax]

Ah that is nice! Procycle oil will do as the MT-03 is not a high powered engine. I never had any problems with the bike after replacing the oil with Procycle oil. But I would not know if I would use it in a Yamaha YZF-R1. But that might even be no problem. Brands sometimes have higher prices to make you think it is a good product. Maybe Procycle oil is produced by Castrol or Motul or who knows.

This is not a MT 03

[@MotoSnax]

Well, what is is then? :) In the mean time, after releasing this video, Yamaha also made a new MT-03, the full name is 'MT-03 ABS', a 321cc twin cylinder bike. This is the 660cc one. Yamaha should have never named it MT-03. They should have named it MT-321, as the 660cc is way cooler than the 321cc version.

[@marmol469]

@@MotoSnax I have a MT03 321cc and I said this is not like mine Now I understand I was looking information about oil change Thank you

[@MotoSnax]

Oil change for the MT-03 ABS (321cc) is easier than an oil change for the 660cc. Hope someone else has a video for the 321cc version for you. I will update my title so it won't be confused with the 321cc in the future.
