How to clean a dirt bike engine - 300 Hours WR450 build

Hey guys today we are going to work on our 300 Hours WR450 dirt bike build, we will wash the dirty engine and get it ready for disassembly. My friend Jay Clark from ‪@dirtbiketv1‬ will show us how its done! Remember that your engine would not get this dirty if you wash your bike often. Cheers!

How much water did you find inside it after pressure washing it without the case breather's blocked off ? :)

[@chrisvozza6530]

Very nice. Big difference

[@townsendYXZ]

Nice tips Rado need to do this to my 05 KTM 300 MXC it definitely is in need of it. Now I got a general idea at how to go at it. Thanks keep at it my man

[@dirtniron]

Thanks bro glad you find it helpful

Soaking engine parts in diesel for one night or so will remove everything. Best cleaner out there.

[@dirtniron]

Thanks for the info

I have a yz450f 2005 and since last rebuild she run more than 500 hours just oil and filters change and coolant when I take engine apart looks like new, change piston, connection rod, rod bearings, valve adjustment and she runs perfect again. Ready for more 500 hours.

Damn that's a long time on a proper mx bike. You surely must have lost quite abit of power with 500 engine hours... I had a crf 450r road legal and I had it about 50 hours and it was losing power ( needed a new top end ) not sure how many hours that was on the top end though. I've got KTM exc now less maintenance than full on mx bikes

[@zardportugal]

It is not easy to do, it takes time and patience.
Good job.

[@sirkwisbe]

God bless this man

[@hexhead5732]

Good idea using different cleaner 👍

[@dirtniron]

Thanks 👍

[@MatthewG_208]

I have found the aluminum cleaner to make my engine cases darker than before

[@dirtniron]

scrubbing bubbles takes that off..

[@esingleton6357]

Engine came out nice

[@dirtniron]

Thanks 👍

[@mikeguliz]

Hey Rado i vap blast my cr 500 build with out taking it apart plugged it all up was a little worried but was plugged up well and came out great and no issues

[@dirtniron]

thanks for sharing brother, we will take it apart soon and decide what gets blasted

[@keithtarrier4558]

If you are going with plastics that are not blue, than cercoat in Yamaha blue. For example, black plastics from the tank back, white front fender plastic, around headlight and YAMAHA blue ceracoat.
Then for graphics... mostly blue and black on the white plastics, and white and blue over the black plastics. (and logos in a medium grey that stands out.)

[@dirtniron]

interesting idea, thanks brother!

[@tonybrito1401]

A HEATED PRESSURE WASHER WILL GIVE YOU THE BEST REULTS , I WENT TRHOUGH IT ON MY ENGINE AND HOT WATER GETS EVERYTHING OFF THE BIKE . LESS SCRUBBING , ALSO IF YOU USE A 1000 GRIT OR 1500 GRIT SANDPAPER WILL HELP ALOT ALSO

[@dirtniron]

thanks for sharing!

[@VikiSmx]

Rádo, prosím už skončí s tím tvým kanálem. Když jsem tě začal sledovat... super rady atd. Dnes jsem si koupil další motorku a žena už je celkem nasraná 😂. Původně jsem byl úplný nováček. A teď je mně chodí lidi pro řadu, všechny mám z tvých videí. Takže na jednu stranu moc dékuju na druhou to vypadá na rozvod😂😂😂😂😂

[@dirtniron]

haha, daj jej moj email a daco vymyslime... moto - couple counselling ;) alebo lepsie ked pohovori z mojou polovickou ;)

[@VikiSmx]

@@dirtniron parádní nápad, as usual. 😅🤣

[@josephforcino6399]

What brand scrubbing bubbles did you use ?

[@gasi9613]

Engine already clean.. just dust…

[@298CRE8]

Forreal should see my engines basically have to rebuild every inch once it's been sanded back years of abuse 😅 not one rusty bolt says it all

[@zackk695]

That aluminum cleaner did not work. I wanted to see it look like new after letting the cleaner sit then scrubbing it with a scotch brite pad. Now what really works best is a wire wheel of all shapes and sizes. You will need some very tiny to get into small areas. The big ones that are about 1/2”-1” you use on a drill and the tiny wire wheels you use a dremel tool. The engine then needs to be buffed and polished like you would do a car. This will make the engine look new

Are Yamaha still using magnesium covers, if so probably don’t weld it 😂
