Ultimate Oil Change Procedure and Tips, KTM / Husqvarna / GASGAS 450 / 500 / 501 EXCF

Great info thanks! I knew I was doing something wrong with my oil changes I need to remove the engine first. Access to bolts appears much easier!

[@TACOMOTOCO]

We pull the motor to change the air filter. Too much effort?🤷🏼‍♀️

Great video. Started running rotella t4 on my 300 ktm after 100 hours. It feels better, shifts cleaner and oil change at 25 hours look cleaner than the motorex, less goo. I’ll continue using it on my new 2023 when I get it. I do trust shell to MA certify, I mean they’re one of the biggest oil companies in the world with a massive engineering dept - if you can’t trust their label we’re screwed.

[@BLSdarrin]

I have bought 3 new bikes over the years, '15 xcw , 18 xc. 22 xc and numerous older bikes, all Rotella T4 , changed often with no problems.

[@coderedcamaro4812]

Mike you are the ultimate in ktm knowledge and how to. Very much appreciated the video as always. I use a magnetic pen to pull out the filter.

[@michealburnett7877]

Mike, I'm going to dub you the "Professor of the 500". You explain in all of your videos so completely. Thanks for all you do!

[@jackbaldwin6177]

Use a 6 point socket and they won't get rounded off, plus you should never apply that kind of force. Listen to Mike, he's giving great advise

[@race8427]

Your right on track with your analysis of oils. Both Shell Rotella and Mobile Delvac are refined to a higher degree than other motor oils due to requests long ago by the trucking industry to manufacture an oil to endure longer oil change intervals. OTR trucks can go well over the 5-7k intervals in cars and light trucks. It possesses a strong film strength and is more resistant to thermal breakdown. I’m not sure a motorcycle clutch would require an oil with strong film strength. Also it may well be money pitched out the door as most riders will change oil at 500-3000 miles. Cheap oil works, it’s less refined and it’s user will experience varnish in time. I used Motul for a bit then switched back to Phillip 66 x/c Aviation 25-w60. I know it expensive and overkill but I figured if it’s good for a radial aircraft engine with all the shearing metal components from run in to end of service life it should be fine for a bike.

[@seatroutadventures9492]

Thank you for displaying the oil bypass ball. I did exactly what you talked about, removed the wrong drainplug. But now I know it is just to put back the ball with the spring and tight the bolt again. 😁

Very interesting information on JASO tested oil. I would imagine JASO charges big money to test oil therefore shell doesn't want to pay it. I know monopolies within the testing industry are extremely prevalent.

[@Nicky_Pin_It]

Another Tip: Buy one of the billet metal Oil Fill caps. Over time those plastic ones get boggered up and can potential cross thread. The billet ones have a better fitment, and can be secured with a wrench. They run about 20$

Great video! The info in all your videos are very helpful. Just picked up a 2024 KTM 500 EXC-F doing the one hour oil change there isn't a screen on the lower drain bolt. Repair and Owners manual have them. However, doesn't look like they are on the parts diagram online at KTMpowersports. Just wondering if you knew if they are supposed to have them, or you could use your influence to find the answer. So far two shops say they haven't been coming with the screens in them.

Thank you , I really value your videos. Also, thank you for the links and the part numbers. I’m running a 2013 KTM 500 EXC. This weekend I was distracted during the oil change and I ended up pulling the oil pump cover off because I mistook it for the oil filter cover.... duh.

[@skinnybricks]

Changed the oil in mine for the first time a week ago. Followed the steps in the Owner's Manual. Does it matter the order in which you remove the plugs? I'd rather much remove the plug under the engine first. I made a huge mess accidentally pulling out one of the side plugs first. I'll be more prepared next time.

[@Danman1972]

On my RFS I would pour oil on the inside of the filter and turn it until the outside was soaked.... then insert it. Works well and the RFS had two filters.

[@getitoffroad4750]

The book for the 21 500excf says 1200cc or 1.3 quarts of oil is the capacity. I found this to be a bit low so the Taco man sight visual on the glass sounds like a good idea at least until you know exactly what you should put in there.

[@Papparratzi]

Good overview, a must watch for new owners of the KTM line. To clarify, Shell does have oils that are indeed MA rated. They are submitted under Red and Yellow co. However, Rotella is not one of those listed. The fact that Shell does have JASO MA rated oils but Rotella isn’t one of those leaves me skeptical about Shells claim that Rotella meets the JASO MA specs.

On the side plug pickup screen, mine was fit tight in the cap. It came out with cap. I did remove it for cleaning. But it snapped back in the cap for installation. It "seemed" to be self aligning and seated well when I tighten the cap. Does this sound correct ? I am tempted to drain oil even though I just changed it so I can inspect the orientation.

If you've got an engine with a hydraulic cam chain tensioner, oil choice can have an impact on startup and idle noise levels. Clutch and shifting too. I agree though, oil choice has very little impact on the lifespan of engine components.

[@Big_Yum]

Great video! Just one question, so I just did my first oil change on my bike and I didn't presoak the oil filter, could this cause any damage to the bike? I rode it for probably 5 minutes after changing the oil to get it all to circulate

[@TACOMOTOCO]

no worries, but next time you'd be wise to pre soak or half fill the chamber.

[@Big_Yum]

@@TACOMOTOCO Thank you for the reply! definitely will do that next time.

[@Big_Yum]

@@TACOMOTOCO Also just one more question, my manual for my 2021 exc says to fill 1.2L and I can't find the 1.6 number anywhere, will this number vary from 450-500cc bikes? I currently just have 1.2L in mine right now

[@BAYAREAMX]

Absolutely no need to pre soak an oil filter. The entire engine is coated with oil internally and as long as there is oil in the sump when you start it you’re good. Don’t make it more complicated then it needs to be.

[@TACOMOTOCO]

@@Big_Yum note that we don’t fill our bikes to a specified ‘beaker measured’ amount. Rather we use the sight glass method

[@anthonycurtiskeller3082]

I see you have your water pump cover off. What’s your opinion on the boysen supercooler water pump upgrade for a 500 EXC-f?

[@John_Doe_6996]

I installed the super cooler on my crf250R, which used to overheat from slow rides or idling, dropped my temps significantly, no longer losing coolant. Also used in conjunction with a new radiator cap, and some engine ice coolant. It’s probably worth the money if your bike runs hot or is overheating in some situations.

[@MackB2023]

Oil filter change use the tip on side technique.. moe beta ;)

[@bearbeau13]

Overkill with saturating the oil filter. Plenty of oil on the moving parts. The internals are faaaar from dry and you run 0.0 risk on startup before that filter starts circulating oil. Just a heads up, been dropping dry filters in hundreds of ktm 4 strokes over 30 years(primarily race bikes) and ive never had an issue. Ever...

[@farmer3242]

If you put a oil bolt in you should tighten it straight away because you may forget and leave it a bit loose and it may fall out, also a bit of new oil on threads of bolts is a good idea, not dry threads, IMHO, awesome helpful video, thanks

[@dirtrider9268]

One aircraft mechanic commented on another video how dry and wet torque specs are different, by as much as 40% for aircraft engine torque settings.

[@usa45v26]

Any reason why you pull the engine screen last?

[@uncletom1971]

What could happen if you filled oil up to the top of the window, like at the top of the red circle (not top of the complete window)? On other bikes there are two indicator lines on that window; one for the lowest volume, and another near the top of the window for the max volume to fill. On my KTM that red circle corresponds about that same proportions within the inspection window. I think you're OK filling oil to the top of that red circle in the window. Am I wrong?

[@dirtrider9268]

The Manual says middle. The level varies greatly on the RFS KTM, from cold to full hot levels in the glass. It was a shock to me till i realzed it. The new doesn't vary as much.

[@uncletom1971]

@@dirtrider9268 So, the middle is in reality the maximum and the minimum at the same time. There is no tolerance?

[@dirtrider9268]

@@uncletom1971 I don't see the new motors varying. So maybe middle is the "ideal". Should you siphon oil out if over that, I would if its always at the top but I want my engine to have ideal wear, conditions, etc. I wish I was smarter on this but I'm not engine builder.

[@ktmredbull100]

Wow that's a lot of metal coming out of that engine in only a couple of hours. Based on this test of oil coming out of new motorcycles it would be a good idea to change the oil as soon as you get the bike i.e. The factory oil is often contaminated with metal: kzbin.info/www/bejne/b3ikhqJumrqLm7c I do a regular oil analysis on my bike and oil drop test to measure wear. To reduce circulating particles I use a magnetic sump plug and a foam air filter. The magnetic sump plug also provides an indication of how much wear is occurring. The wear in my road/trail air cooled bikes is a fraction of that found in this trail bike despite 6,000 km oil changes. Ouch!!! :-)

[@voide4233]

Don't think you should be following the recommended oil from a person who is using an old Japanese bike that is De-Tuned for reliability. 500cc engines that are newly designed put out 50-70 hp and require more maintenance compared to 1990s designed 250cc that puts out 20 hp or 650cc that puts out 40 hp they can't be compared maintenance wise.
