Quick, extremely informative, you explain things in the most simplest form, if somebody can't figure out how to change your oil after watching this video they need to stop writing motorcycles and maybe get a a trike bicycle or something, maybe a two-seater bicycle..... Because you are duuuuuuuuuuumb. 😅 Great job dude, you got a new subscriber 👍👍 Take care, ~Jonny5🥁

3 years later, still a good help! Thanks!

[@ShutdownStranger]

I appreciate the comment about the thick/thin ends of the long screen. Pretty hard to notice there is a difference by eye otherwise.

[@lustmaster770]

Excellent video, I just bought one of these bikes and wanted to do an oil change, I saw the twin filters had no idea about the screens. Thank you

[@SamsungJPrime-dm8gp]

sir u need to fill the oil filter with helf of oil . when u reaplace to new filter. this is even writh on service manual. the reason when u start the bike there is few second until the filter oil is fill and the bike upper enigne dont get oil .. this will not destroy your engine if u didnt do it. but i think for the long run. this will be effect. btw i have exc 525 2004.

[@Dansyoung]

No it won’t. There’s a second or two maximum to build up the oil pressure, residual oil inside the engine will take care of it.

[@tbd6403]

@@Dansyoung He said it wont destroy your engine. I can say from experience, on my 450 that it definitely effects the amount of oil i have to put in. I have done it both ways and if the filters go in dry you need to add more than the factory recommended 1.1 L(whatever it is)

[@92clintonr]

You need to tip the bike on its side, fill both oil filter cavities half way before installing new oil filter.

[@jayinla228]

crazy how you just made 3 videos and dipped out. This one is great and it wouldve been nice to see more content

[@grantdickerson7749]

He did not change the oil correctly. You need to lay the bike on its side to refill the oil filters otherwise you will scar your cam.

[@jayinla228]

@Grant Dickerson you're right. You are supposed to lay it on its side for this.

[@Bok2022st]

Thanks for showing the differences in the filters the size differences between the rear and the front I've seen many videos and they do not show the difference but it is obvious when you take them out but it isn't obvious before you order great video

[@jayinla228]

Great vid, have you made a how to vid for checking valves on RFS?

[@user-zb8tw5kj1z]

Hello, I’m trying to locate the tool that you use in your video to remove and reinstall the side oil screen. It’s very tough to put the screen back in without the tool. I’ve checked Amazon and the dealership and no one can seem to locate the tool. Per your video, it’s shaped like a T. Any idea where to find this?

[@rrandydduke]

Thank you bud 👍🥃

[@2012Crysis]

Somebody knows dimensions of the oring from the short screen? I cant find and my oring is broken

[@mrjacko13ify]

hello my friend I've recently brought a 2006 525 exc I've gone to do a oil change and noticed there is the main oil drain plug on the bottom of the engine at the back and only 1 oil screen drain plug on the left side by the gear lever but not any other drain holes for the little oil screen, I thought the 525 exc had 2 oil screens 1 long and 1 short is this normal on 525 exc,s or do they all have a long and short oil screen, thank you my friend....

[@martinc4251]

Hello I have been searching the whole internet 😞I have a 525 EXC from 2004 in Europe and I want to mount supermoto wheels. However I have no idea what size to buy, especially the axles... is it 20mm rear 20mm front??

[@ghermanalin3353]

hello ,what battery do you use on the ktm 525? do you have an automatic decompressor?

[@totiwars8333]

Little tip here: ( this is mentioned in the manual too ) the oil should almost reach the top of the sight glass because than it is on the maximum so if it falls over or especially in a wheely it gets the oil better, u have a little longer change Intervall and Zou don't have to worry about the burning of the oil so in 20 hours it defenetly won't go ounder minnimum

[@bouncinnn450]

no!!! to much oil destroys the oil pump!!

[@dustincookson5479]

How are you liking yours so far? I just got one a few days ago... I have to fix the hydraulic clutch slave before I can go riding though

[@jonny555ive]

​@@dustincookson5479 I bought mine at the end of winter (2024) 2005 KTM 525 EXC, it had 2600 miles on it..... That's it, I had to buy a new chain oil change and the back tires got about 40% on it. I upgraded my tank to a 6.6 gallon desert tank and put a couple of more adventure mods on it, And dude let me tell you, this bike is fire..... FIRE. It rrrrrrrrripps. I couldn't be more happier. PLENTY of power and I thought maybe with the bigger tank on it the center of gravity was going to get messed up but it only made it better. And I can ride all day and still make it back home on 1 tank. I don't think I've ever had a better bike than this, and I've had lots of bikes....... I see your comments from 3 years ago, do you still have yours ? What do/did you think of it ? I am anxious to hear back from you. Take care, ~Jonny5🥁

all my plugs are stripped except the Allen one, what do I do?

[@toughereaglegaming939]

[@user-sn4zp2ny5e]

Turn the bike upside down and drain through filler port

[@s2k_jb]

Old video but tip the bike on its side when changing the filters!

[@etherform6620]

the manual instructions call for placing the bike on its side, filling the oil filter housing half way with engine oil as well as filing oil filter with oil and placing into filter box.... did you follow this step?

[@kslats916]

You are exactly right. This step is very important for getting oil into the engine more quickly upon restart. The other thing it does it not spill oil all over the side of the engine. If you're careful you won't even spill a drop. Another thing that's worth mentioning is that the internal hex in the stock bottom screen cap is prone to stripping. If it does, it can be removed with a stubby easy out. After that you should install the newer designed cap that has an internal Torx and 13mm external hex.

[@PlantedTankPT]

I have the 450 2007 manual and it doesn't say that. But I've seen people do that on older bikes than rfs

[@moto_leprechaun]

how would you do this on a quad?

[@vxlgsi]

@@moto_leprechaun soak the filter in oil before fitting or tip quad on its side

[@tristatetuners]

@@PlantedTankPT I have a 2007 450 owners manual in front of me right now and in the 4th step on page 50 it certainly does say "put the motorcycle on its side and fill the oil filter housings about halfway with engine oil. fill oil filter with il, place the long oil filter in front and short oil filter in back of the filter box."

[@grantdickerson7749]

It would be interesting to know how many hours he got out of this bike changing the oil incorrectly. Normally it's around a hundred hours after this oil change at a maximum before the cam will snap in half.

[@Evil_Morty2000]

What was incorrect?Not filling the filter cavities with oil?

[@grantdickerson7749]

@@Evil_Morty2000 You have to lay them on their side to refill the oil filter housing And install the oil filter caps as so there are no air bubbles.

[@graemesydney38]

[@vxlgsi]

The hex key sump screens tended to be very soft and round off so they swapped to a torx type so lots of people swap to the torx just to be safe.
