How to rebuild KTM 2 stroke engine - KTM 300 XC build 

This guy is awesome never seen a motor put together so fast

You know Brad knows what he's doing when he uses a 2x4 wood block to rest his engines on...

Just something so satisfying about watching a master technician work their magic. Killer job as always brad engine looks amazing.

Love it brother! “Dirt n iron has posted a new video” has gotta be my favourite notification!!

Always an absolute joy to watch an experienced hand rebuild .. great vid

that was an absolute pleasure to watch. the engine looks fantastic.

Why is this so satisfying to watch I’ve watch this vid 2 times now in the same hour 😂

That was very cool. I couldn’t stop watching! Vapor blast, Cerakote, and Spec Bolts made it look good, too!

Brad is so quick great job would like to see a video on setting power valve and z dimension on 300 ktm 2010 up model

Este es el video que estaba esperando!!! Gracias. Saludos desde Colombia Dirt and Iron

Damn Brett has it down! Look at him go. 🙌🏁 Great video... proper lighting and in Focus - one of the best I've seen.

This engine looks amazing! Honored to be your bolts of choice on it!

What a handsome engine 😎 Like I said before, these full engine disassembles \ rebuilds are fascinating to watch. Thx Brad for the show 👍

The engine looks awesome. Wainting for the next chapter.

this guy knows what exactly what he is doing, he is an artist

Awesome, he sure knows what he's doing 😎👍

Them engines are so simple, well all 2 stroke are but KTM is a pleasure to work on imo.

So for anyone watching this video as a reference: The dot on the Kickstarter ratchet gear is supposed to be offset with the marking on the shaft by one spline. They are not supposed to be lined up.

Nice and clean jod my friend👌👊✊💨

Really satisfying content, cheers guys!

Soy de Guayaquil ecuador la verdad que deberían dar cursos de mecanica de moto ustedes están a otro nivel. Parece que fueran de la nasa. Sus herramientas son bacanes. Sigan adelante bendiciones. Si tienes una moto vieja me la podrías regalar 😀

You sir, are an artist!! You clearly have a passion for what you do! Wonderful job!

Anyone who says I don't need a torque wrench, RUN AWAY. Quality work requires experience and following procedures.

This needs a Grammy nomination.

Great video. Amazing work.

Very nice video and engine Rado!! Let me know when you get it fired up!

Love the builds keep it up bro 👍

Awesome build gentleman!

Thanks for sharing. Great job done.

Mine is a 13 and the clutch set up is the new style with the Bellville single spring washer and the dampers in the hub. I don't think Hinson makes a basket for the 13. Will need one in the future for sure. The stock ones KTM must gold plate them. Basket is not cheap at all! Wish there was a billet replacement. I replaced my clutch and the internal dampers around 120 hrs or so.. This is the build I was waiting for. I have a 13 300xc currently. Debating on trying to move to the new frame and counter balance and pass this one along or throw some money at it (suspension, chassis bearings, and plastics and graphics.... etc.... )

Looks amazing man

Nice video! I was expecting the most difficult part, when he puts the rings, but you cut it!!

What lubricants and sealants do you recommend when assembling motor

hello where do you get the spare parts of the engine and the gears

This was excellent to watch as usual. Does Brad mention the need for, or have you seen him do a leakdown test on his builds? I’m guessing his build have zero air loss but just wondering.

Great video awesome build. Dude has lots of experience with those engines. But I'm really curious about the reasoning of the double gasket under the jug? I've never seen that

always enyoing watching a video like this

Where is your shop located? I’m in Keller TX and have a 98 300 MXC that needs going through.

Do you guys know the orientation of the cylinder studs ? Is the shorter side inside the engine case or facing the cylinder ?

The engine looks great

Good video with expert engine builder, but I did not see or hear anything about the rubber O-Ring that goes on the crank shaft, the rocky mountain ATV video in the same subject does show this, I just thought it was strange that it had an O-Ring on the clutch side of the crank; so I wanted to hear more about this part.

A huge thanks to Brad for sharing his amazing craftsmanship which will provide someone several hours of enjoyment and exhilarating fun!

Great video!! - What is the purpose of "pinging" those screws in the clutch basket installation? Extra protection from things coming loose over and above the red loctite?

Does anyone know will a rebuild kit for the 2004-2005 work on a 2000?

Nvr seen a center casket like that bad ass man

The best part for me was the wood engine stand. I'm making one for the next motor

Good job

Beautiful motor I’m a Yamaha guy but that’s a solid motor

This is awesome guys and great job. Another good tip is for the exhaust manifold as I see it’s spooging. The seals aren’t sealing anymore from vibration wear. Go to McMaster.com and get the next sized viton O-Ring it works like a charm, no need for messy RTV silicone. Same deal with the sprocket, the seal always leaks behind the front sprocket. If you can wiggle the front sprocket once the clip is on that means you’re gonna leak or it’s already leaking. Get the next sized o-ring and it will go away. Both of these o-ring tricks are permanent fixes and not a temporary resolution. ⭐️⭐️⭐️⭐️⭐️ to your vid. 😘👌

came out awesome rado ....

Are the hotrods bottom end kits good or should I just go with a oem crank, I’ve heard mixed reviews on hotrod cranks

Awesome awesome awesome!!!

How you cleaned your engine box so nice ?

Sir The hinson cover in engine it is customize? How much if I order?

Donde puedo comprar equipo de esa motos.

Im after a cdi for a 250 ktm 2001. Any ideas where I can get them from

QUAL NOME DA TINTA Q PINTARAM O MOTOR::

where can i buy the electric ignition kit of a ktm 250 xc-w 2009 online

Hey buddy.. I am loving the way your build is going motor came out amazing..we did about the same things with our motors.. oh it’s Matt .. I had emailed your pics of my 2012 300xc build.. I did the same piston.. great choice.. I also did the ktm clutch plates in a rekluse basket with the z.start pro clutch.. I like that clutch better than the newer designs cause it still functions like a regular clutch.. you could bump start it also if ever needed.. but also worked as an auto if wanted.. and did the rekluse cover cause it gives you some more oil capacity..and it’s a beefy cover.. my buddy did your Hinson on his 250 it’s also very sweet.. glad you did the V force 4.. they performed great on my build.. did you up grade the starter motor with the newer bigger one cause the 2012 motor is weaker and has issues..it’s worth every penny to change it out ! Man brad really did a great job I watched his work and we do the same things. I did the silicone in the same areas and all lol .. he is a good engine guy !!! I like the head you got... slavens has a nice one also and you can get different interchangeable combustion domes for it really trick.. oh one other thing with that motor.. the place is water pump impeller..they warp with heat.. Ktm has a sweet high flow one.. it has larger blades it also aluminum..it moves fluid faster.. works a lot better for hotter conditions..can change out easy enough later.. but I do recommend doing so ... well my friend it’s coming along awesome..oh and love all new bolts also.. hahahahha makes a difference! Man your gonna love her so much when your done she will be a monster ..ok man waiting on the next video. Be well

You made that look to easy. I may have gotten the nerve to do one myself from your video. Thanks

Awesome

OK...we don't know the thickness of the base gaskets and the rationale behind that choice. Also, didn't see you set the "Z" dimension or the verify the "X" dimension. I know...being a technician AND a narrator is not easy. Excellent rundown on putting her back together.

You can use the newer version inner clutch cover gasket and it's way better and won't leak. That old style inner clutch gasket will leak on you!

Great vid as always Rado ,I have always used OEM cranks how good are the aftermarket cranks in terms of reliability /longevity as opposed to rebuilding the original crank with a OEM crank pin kit ? Cheersd

Hey rado i have tried for over a year to get in touch with brad is there any way you can pass the message or tell me what his process is to get work done?

Is that the plastic water pump?

what does it mean when you torque the it down and the trans become hard to spin

What is the song

I`m not an expert and i think that he`s very qualified and professional, but what about use of the torque wrench?

Hi, nice and interesting video. Like how much does this cost when there is no sponsoring?

Why double gaskets on bottom cylinder because of squish measurement??

Do you want make a video of a ktm sx 125 2 takt

Locktide on the piston rings?

What color is the cerakote?

What is the price

No balancer??

Buy a Avenger220 cruise and make videos on that

Trying to learn and do some stuff at the same time, but this intense loud music is not helping

😍

Hey Brad got polish flag on his cap ;)

C est moi ou il fait zéro serrage au couple ?🤨

No cross pattern

Those cases went together like butter wtf

that wooden box has seen allot of rebuild motors.

How much one set......

great video ,wish u would explain more and use less music

Sweet 300 stroker is gonna rip

Nice video

This guy is to engine building that John Goodman is to acting.

Since when does a thicker base gasket give you more stroke?🥴

You forgot the crank o ring.

Yeah I don't care how many engines you build per day, if you can't spare a few more minutes to get a torque wrench to properly torque your bolts down and instead just do it by feel because it's "faster", then you're not touching my engine. Don't get too confident in your skills, that's when mistakes happen. Take your time, make sure it's done right.

Lol! No sir the head does not change the stroke!! The head changes the squish which in turn changes compression which in turn changes the fuel used race or pump. Which I turn changes your bikes power either low end or top end! But the stroke remains the same based on the length of the rod! 😂 I think the language barrier caused confusion an md he used the wrong term possibly

You think that China crank is better than new oem lol.

Step 1...sell the bike to someone who’s just as willing to buy overpriced dirt bikes as you are...step 2 ...take that money from the sale of 1 KTM and buy 2 YZ 250s 😂👍

Getting famous off of comments day 245, so I can live the dream, live every day like it’s your last🤙🚀🚀

มึงจะรีบไปไหนประกอบเครื่องใจเย็นๆก็ได้ไม่ต้องรีบสาด

To the greenhorns this guy appears a master tech ... To the actual master tech this guy IS a greenhorn and would NEVER be allowed to touch an engine. He is a perfect example of the thousands of yahoo's that are being rubber stamped through the MMI system.

Music is ruining what could be a great video, hear the guy talk, then music ruins it. Come on man, you could've done better

Yeah because real professional mechanics dont use a torque wrench because "they assemble a lot of engines every day and it takes a lot longer" sure man
