This guy is awesome never seen a motor put together so fast
Lets see him rebuild a 450 4t engine that fast ahaha
here you go :) th-cam.com/video/r3Cm6ew7PDs/w-d-xo.html
@@JakePT2k He does! I think he has been doing this a while. He also does motors for Jay Clark at Dirt bike TV as well. I wouldn't hesitate to mail that dude a motor and a box of parts!
You know Brad knows what he's doing when he uses a 2x4 wood block to rest his engines on...
haha, thats right!
Just something so satisfying about watching a master technician work their magic. Killer job as always brad engine looks amazing.
thanks, glad you like it brother!
Love it brother! “Dirt n iron has posted a new video” has gotta be my favourite notification!!
thanks brother, appreciate it!
Always an absolute joy to watch an experienced hand rebuild .. great vid
Glad you enjoyed it! thanks
Este es el video que estaba esperando!!! Gracias. Saludos desde Colombia Dirt and Iron
that was an absolute pleasure to watch. the engine looks fantastic.
Damn Brett has it down! Look at him go. 🙌🏁 Great video... proper lighting and in Focus - one of the best I've seen.
@All Time Productions hah! Funny. Ok got it straight now 😂
What accent? 😂
The engine looks awesome.
Wainting for the next chapter.
thanks bro, hopefully soon!
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.
Anyone who says I don't need a torque wrench, RUN AWAY.
Quality work requires experience and following procedures.
he does use it, not on everything tho. Brad has tons of experience
Why is this so satisfying to watch I’ve watch this vid 2 times now in the same hour 😂
glad you like it Kevin! feel free to watch as many times as you want ;)
this guy knows what exactly what he is doing, he is an artist
Brad knows his stuff, thanks man!
This engine looks amazing! Honored to be your bolts of choice on it!
Thanks again!
That was very cool. I couldn’t stop watching! Vapor blast, Cerakote, and Spec Bolts made it look good, too!
Glad you enjoyed it! thanks Aaron
What a handsome engine 😎 Like I said before, these full engine disassembles \ rebuilds are fascinating to watch. Thx Brad for the show 👍
Glad you enjoyed it
This needs a Grammy nomination.
haha, glad you like it ;)
Really satisfying content, cheers guys!
Glad you enjoyed it!
Awesome, he sure knows what he's doing 😎👍
Thanks Ian 👍 he sure does!
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
thanks Quinn, lets see what we can do
Them engines are so simple, well all 2 stroke are but KTM is a pleasure to work on imo.
Great video. Amazing work.
Glad you enjoyed it! thanks
Love the builds keep it up bro 👍
Glad you like them! thanks Jayce!
Awesome build gentleman!
thanks Michael!
always enyoing watching a video like this
glad you like it Martin!
Thanks for sharing. Great job done.
Thanks for watching!
The engine looks great
thanks, glad you like it!
Looks amazing man
thanks Dan!
Very nice video and engine Rado!! Let me know when you get it fired up!
Thanks! Will do!
A huge thanks to Brad for sharing his amazing craftsmanship which will provide someone several hours of enjoyment and exhilarating fun!
thanks Kimo!
Awesome awesome awesome!!!
Thank you! Cheers!
You sir, are an artist!! You clearly have a passion for what you do! Wonderful job!
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 😀
Nice and clean jod my friend👌👊✊💨
came out awesome rado ....
thanks Brad :)
Nvr seen a center casket like that bad ass man
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.... )
thanks for sharing Danny! I think these bikes will hold their own compared to 2017+ personally I don't really suffer from the vibrations on the older KTMs, they still quite balanced compared to some other older 2 strokes
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
That’s to set the correct squish distance between the cylinder head and the piston. You can play around with gasket thickness here to make your compression higher or lower but I believe KTM uses 2 gaskets from the factory it is just hard to tell because they are usually stuck together when you disassemble it.
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.
What lubricants and sealants do you recommend when assembling motor
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.
glad you like it. No need for that I think.
Nice video! I was expecting the most difficult part, when he puts the rings, but you cut it!!
Glad you liked it! it was very quick and I did not have good shot of it.. sorry
The best part for me was the wood engine stand. I'm making one for the next motor
cool!
Do you guys know the orientation of the cylinder studs ? Is the shorter side inside the engine case or facing the cylinder ?
Beautiful motor I’m a Yamaha guy but that’s a solid motor
thanks Michael, glad you think so!
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. 😘👌
Getting ready to replace my counter shaft seal o ring this week. Do you know the dimensions and/or part number four the bigger o ring?
great tips, thanks a lot. I believe allballs kit comes with thicker oring for the countershaft seal
I have this problem with my 2015 ktm 150sx... which size o ring should I get?
Awesome
thanks man!
Good job
Thanks
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?
Thanks Dan, yes thats the purpose, just to be safe
Where is your shop located? I’m in Keller TX and have a 98 300 MXC that needs going through.
Are the hotrods bottom end kits good or should I just go with a oem crank, I’ve heard mixed reviews on hotrod cranks
they are good, I had no bad experience.. oem is great too :)
hello where do you get the spare parts of the engine and the gears
Does anyone know will a rebuild kit for the 2004-2005 work on a 2000?
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
hey Matt, thanks a lot for a great feedback and tips, I will look into that water pump mod. I got new starter from allballs, works pretty good now
Doing a 2012 300xc as well and went with the Hinson Basket. I noticed Tusk sells a Competition clutch kit with heavy duty springs for this model and year. You guys think OEM is a better product than the Tusk offering?
@@danhansen4855 hey Dan.. I really just like the feel of the stock clutch feel ..I have ridden bikes with other clutch packs and I like the stock set up the best.. Hinson basket is a fine choice..I do like the cover also much better than stock ..it’s thicker than stock and stronger and looks awesome! As far as the tusk clutch pack it’s ok but the Ktm can handle lots of abuse it’s great and fitment of plates is butter smooth..the best thing always is the basket when plates wear and the basket gets notches in it your plate don’t slide back and forth very well.. most people overlook that when doing the clutch rebuild..they file the notches down .. it just makes a temporary fix but creating slop and the plates hammer the basket more when on the gas and when on the brakes.. I do hope some information helped bud and enjoy your build.. that bike is a monster !
@@matthewkrisowaty7053 Really appreciate the feedback Matthew, OEM clutch it is!
QUAL NOME DA TINTA Q PINTARAM O MOTOR::
😍
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
I’m wondering the same thing, I’m rebuilding my yz and I’m pretty sure I’m going to go oem but the hotrods bottom end kit it cheaper than the oem crank itself, so it’s a little tempting. I’ve heard People say it’s a dice roll with hotrods cranks, especially wisco.
@@aaroncrain2343 ,
I spoke with a 2 stroke specialist ( who shall not be named lol) and asked this question ,answer I basically got was this :
OEM crank rebuilt with OEM crank pin /rod kit or with a prox crank pin/ rod kit ,best bang for buck with the best parts which is what I thought the answer would be .
I will get my crank rebuilt or buy a new OEM crank hope this helps
CheersDerek.
I had no bad experience with Hotrod, Brad also doesnt have anything bad to say.. their rods are made in USA
@@dirtniron thanks Rado , I don’t like to badmouth anybody,s product there is always that guy who does a bad install or poor maintenance and blames the product, I will stick with the OEM crank possibly using a Pro X rod and pin always had good run with OEM ,cheers Derek
@@dnrg62 I actually just ordered a pro x complete crankshaft for my yz, it’s completely made in Japan and said said to be a rebranded oem crankshaft for aftermarket price.
You made that look to easy. I may have gotten the nerve to do one myself from your video. Thanks
Go for it! Brad makes it looks easy :)
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.
How you cleaned your engine box so nice ?
hydroblasting
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!
thanks for the tip Eric!
Donde puedo comprar equipo de esa motos.
Im after a cdi for a 250 ktm 2001. Any ideas where I can get them from
used ebay or new OEM from RMATVMC
Sir The hinson cover in engine it is customize? How much if I order?
Check the price online there’s plenty of websites that are selling it here in USA
where can i buy the electric ignition kit of a ktm 250 xc-w 2009 online
i got new starter from all balls racing
This guy is to engine building that John Goodman is to acting.
Hi, nice and interesting video.
Like how much does this cost when there is no sponsoring?
The full rebuild kit for most bikes is around $800-1000 and probably $200 in tools. Then all the new parts like clutch and reeds are probably another $500+ easily. The expensive part is the labor. Probably 10-20 hours go into a full rebuild with cleaning and everything.
@@keshmo12 round about 1500$ dfor parts only ? Thanks for the quick answer 👍🏽
@@scratchop6863 yeah depending on what bike. A honda cr125 full rebuild kit is only $350 so you could do one of those pretty nice for $1000.
@@keshmo12 thats cheap with all gaskets and bearings 350$?
Depends, wrench rabbit kit is bellow $1000.. that should give you everything you need to rebuild the engine. Then it depends if you need new clutch and other things..
I`m not an expert and i think that he`s very qualified and professional, but what about use of the torque wrench?
we used it where needed.. Brad has it dialed in
what does it mean when you torque the it down and the trans become hard to spin
doesnt sound right.. something is not ok I guess
@@dirtniron i figured it out i had a gear in the trans flipped and somehow it caused fitment issues
that wooden box has seen allot of rebuild motors.
What is the song
Nice video
Thanks Jadon!
Why double gaskets on bottom cylinder because of squish measurement??
yes, the head was done for that gasket thickness
Locktide on the piston rings?
Its oil
its not locktide 🙂... assembly lube
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?
he is very busy these days. did you try to massage him on IG?
What color is the cerakote?
midnight bronze
@@dirtniron thank you awesome color choice! Can’t wait to see it done!
Is that the plastic water pump?
i think so
Those cases went together like butter wtf
yea, it was pretty easy
Do you want make a video of a ktm sx 125 2 takt
i have some riding videos with 125sx
Hey Brad got polish flag on his cap ;)
haha, really?
@@dirtniron Really really :D
Don't listen to ma bich he's a geographic numb skull. Brad's camo cap has an outline of the Lone Star state.
@@sethfoster4535 for sure
Buy a Avenger220 cruise and make videos on that
what is that ?
@@dirtniron its a cruiser bike of bajaj
great video
,wish u would explain more and use less music
Sweet 300 stroker is gonna rip
hope so!!
Trying to learn and do some stuff at the same time, but this intense loud music is not helping
sorry bro.. tune it down
No cross pattern
No balancer??
nope.. older model
What is the price
not for sale
How much one set......
how much one set of speed reaches how many km / h
?
@@dirtniron 180-250km/h
Since when does a thicker base gasket give you more stroke?🥴
😂no it doesnt, i dont know why i said that. It’s changing the port timing and gives better power.
C est moi ou il fait zéro serrage au couple ?🤨
You forgot the crank o ring.
?
no we didn't i had put it in... no worries
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.
You have an issue with no torque wrench but not the impact driver for installing bolts? Hahaha
@@sniper617 Who said I don't have a problem with that?
you know what they say: "judge the tree by its fruit"
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
The thickness of the base gasket changes the port timing, the head compensate for the difference so the compression is the same- this is my case. You are right, i am learning always. By stroke i meant to get more volume in the cylinder since there is thicker base gasket, but later I learned that the gasket changes the porting and the head is cut accordingly to compensate for the thickness. Hope that makes sense
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 😂👍
:)
You think that China crank is better than new oem lol.
hotrods are good products, rods are actually made in the USA.. but I get your point. I never had bad experience using hotrods
Ya they are ok but ive put over 1100 hours on a stock ktm 2 stroke crank and a hot rods crank won't go that long.
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.
i am a Greenhorn ? that's like the funniest crap i have heard...and didnt go to no MMI that place is a joke ......well keep up the good key board warrior fight..
Getting famous off of comments day 245, so I can live the dream, live every day like it’s your last🤙🚀🚀
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
music covers areas where I speed up the video, Brad was not talking during that time, whenever he was talking you guys can hear it. Nobody wants to watch 2h video of tightening the bolts and nuts.. I found this format to make the most sense.. but of course there are guys with different opinion. thanks for sharing
มึงจะรีบไปไหนประกอบเครื่องใจเย็นๆก็ได้ไม่ต้องรีบสาด
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
he uses torque wrench.. not for everything tho
In the real world it's absolutely done like this. I know first hand. Torque wrenches are used for critical components. Everything else is by the feel of a skilled trades man. This guy is a pro.
