Awesome vid rado i think its great that J and brad are such talented mechanics willing to teach you everything u need to know when it comes to your bikes I love it man keep it up
Currently stripping my 13 rmz450 down to send out to this guy. Saw him all over your page and had to give him a shout when she finally quit on me after 200 + hours of supermoto riding.
i used external Rode shotgun (micro) but it might not be all the way in.. I noticed late.. so I am not really sure if it was built in camera mic or my external. I am using same STM lense as with t5i, it is sharper now and autofocus works much better too.
man this Mechanic is a beast. can tell he's old school for sure he doesn't even use those tusk tool for anything. Man I'm impressed thanks for the video
Great job Rado! The RMZ engine looks really good with low wear for 120+ hours.... That diesel engine oil you use seems to do a excellent job! regardless these guys did a great job on your motor! should pull very strong!!
Rado your very fortunate to have jay as a friend he is a legend....that motors value just went up about 2k because brad built it at jay clarks house.....brad was right at home doing this.....you can tell he knows a thing or two about a thing or two.....while us amateurs study manuals ...brad is who we one day aspire to be....
@@dirtniron thats awesome of you to say..looking forward to the 450 vids keep up the great work...i been watching since you first got the old warehouse...take care man
These time lapse vids are really awesome! So many ch can be learned in a short period of time! You dudes brighten my day every time I watch Dirt and Iron! Stay Moto Vated!!! Do y’all sell t shirts? lol! Thanks again!
Yes, and shout to Dirt Bike TV as well! I want to be you guys when I grow up! Though I’m 51 so I guess I’m already grown up, lol! I still want to be like you guys when I grow up though :)
Are there no torque specifications for most of these bolts? Awesome video. I've got an opportunity at a really cheap '07 RMZ450 with a seized motor. I've never rebuilt a 4 stroke, but I'm motivated to try.
I am currently doing this exact engine and kit. This video serves as a great reference. Would love to pick that guys brain building it. Clearly not his first rodeo. Hahahaha
Awesome build! I have 2013 rmz 250 and I want to remove the judder spring from the stock clutch, but its not clear to me how should i do it. Should I remove the judder spring, judder spring washer and the smaller friction plate and add a normal friction plate?
Where is he based out of? I’m in Fresno and after seeing his work I would like to use his service. Someone who actually knows what he’s doing and seemingly cares about the build. Awesome
How much would the labor on something like this cost? Parts estimate? Also, can you expect a power increase from the new piston (same compression? mass?)? Would this be a got time to do any polishing/head work?
I used stock compression piston, no porting or polishing, still it should run better than before, the engine was little tired, specially the clutch and I am also getting hotcams and full fmf system, I am expecting some power gains for sure
well since so many people are asking about the cylinder hone we did the hone is called a Brush Hone It's perfect for deburring and deglazing engine cylinder walls its made just for Nikasil cylinders ....
Hey Brad quick question, whats your opinion on the idea thst this type of hone ruins the thin niksil coating? About to put my first top end on my 19 250 xc with 100 hours, cross hatching should be fine, would you recommend honing anyway to ensure proper ring seating?
@@davidjo997 ya if you have hone thats made for nikasil if not you can use green scotch bright pad and contact cleaner ..you want to get the carbon build up and deglazing the cylinder that will for sure help with new ring seating
Is it needed to use a hone for the cylinder when changing piston on a Sxf or other nicasiled cylinder? Or are there something else you can use that you have in your house?
Dirt N Iron thx Will do, did check a bit but not all way! Guess I was one of those lazy ones on the internet today! Haha. Great video and thx again for answering 👌
Chicken Mac i have a 2015 yz250f with 316hrs. I’ve only put one top end in and replaced all valves w/ adjustments. I ride and race enduro, still going strong
it was still in decent shape, it would run longer for sure. Clutch was in worst shape but the top and bottom could do more. But since I am doing this build on the channel, it was a good time to go thru everything
Rmz 25O most likely the-same procedure only difference is the sizes? I wanted to buy 2nd hand rmz250 2014 model Id like to rebuild its engine same way you did. My poin it i want to know your exact kit for that haha
@@dirtniron I only said that because I am currently in the middle of rebuilding my 09 RMZ450’s engine right now and cleaning the Carbon off the Piston, Head & Valves are the last thing I need to do before I can put it all back together 🤞🏻
That is sick and wish raptor 250 if you guys can try work out on Yamaha raptor 250 that be awesome to see next time if someone asked you if can rebuild some of 2 wheelers/quad that be nice to help out to look after the engines
Wow! such a skilled confident mechanic
thank you

That was really impressive to watch someone who so obviously knows what they're doing...he could do it blindfolded! WOW!!!
Awesome video and a great mechanic! Thank you for sharing!

Thanks Aaron, yea they are great! Jay has been great friend since the day we first met.
Thanks for this video guys, great job all-round! Watching Brad at work is time well spent for sure, he knows his stuff.
he sure does! more videos with him coming soon
@@dirtniron does he have a business to allow people to send engine to him for rebuild?
Rebuilding my Aprilia sx 50 engine right now and gotta say that four strokes look like hell compared to 2 strokes
yea, couple more bolts on 4stroke ;)
moped gang
I have an aprilia sx 50 as well
Plus a 50cc engine is a bit more simple then a 125 because 50cc doesn't have power valves
Or you’re just dumb
This video was sick, I know both Jay and Brad and they not only build awesome bikes, but they are great people too.
agree 100%
Loved this video, really interesting as someone who is wanting to learn more about the 4 stroke engine! The guy who did it is so talented! Cheers guys
Glad you enjoyed it!
Beautiful engine. Very good job🤩🤩
Professional Work :) Very Nice !
These videos make me have so much respect for my mechanic... without him I’d be SOL... great job man!
glad you like it Jaiven, Brad knows his stuff!
Love the video. Really enjoyed ! A yz450 is coming soon to me
I just got a 2013 rmz250 Sunday I love the bike rips and is easy to get comfortable on
Cool man, congrats!

Cool bro, glad it helps ;)
This guy is a pro! great video! detailed where it should be.
Thanks for sharing with us Rado :)
thanks Nir! I got new dslr, did you notice the quality was little better? I got canon 80d now
@@dirtniron I didn't really, the quality is awesome though.
The thing that really gives a better quality is the lens ;)
What mic was used?
i used external Rode shotgun (micro) but it might not be all the way in.. I noticed late.. so I am not really sure if it was built in camera mic or my external.

Very informative.
Amazing, can you guys come to the east coast to my garage next?
And put on some gloves!!! Lol

Hey Rado the video came out very good ...this is Brad the one that did the motor...lol
but that was awesome
Hey Brad, good to see you here and glad you like the video! you did great job, thanks again!
Hello Brad! Awesome video, do you rebuild engines for the public? I am at about 120hrs on my 2016 450X and am looking to have it rebuilt.
@@stacksmasher yes sir ..
just DM me and ill give you info
thyx
@@brad5664 Looks like your account does not allow DM ; (
I'm also interested in a engine rebuild
Excelent jobs
@ 19:00 That's Rado singing. Pretty good!
Haha, i wish ;)
@@dirtniron what is the name of the song???
handy manny ahh hammer i din see a case splitter used this man is a legends
Love 4 strokes yep
Noice, noice, weddy noice :-D
If i tried to rebuild this, there would be a box of bolts and bearings left over, and it would not run🤣
Great job👍❤
Thanks 👍
😮😮wow nice
Wish i could do that sucks was looking frord to ridening. I keep you up to date
Nice👍
❤Awesome😍
Incredible 4 stroke rebuild, everytime you ride one
every other time as long as you do your oil changes often ;)
What would cause coolant to come out of the over flo when it warms up?
hey can you say me which tool i need for the flywheel from the ignition m24x1,5 or m28x1.5 Greets from Germany
Brad a fuc'n LEGEND !!!!
Good electric torque wrench 😳
Tighten those casing bolts opposite to each other
How much would the labor on something like this cost? Parts estimate? Also, can you expect a power increase from the new piston (same compression? mass?)? Would this be a got time to do any polishing/head work?
I used stock compression piston, no porting or polishing, still it should run better than before, the engine was little tired, specially the clutch and I am also getting hotcams and full fmf system, I am expecting some power gains for sure
Jay, looking good
:) he is staying in the shape, riding like 4 days a week, i wish I can ride that much
Love the video great bunch of information for noobs like me wondering what a rough price for all the required parts cost you in the end
Glad it was helpful! I went all out so its was little more expensive but i guess you can rebuild it around $1500
well since so many people are asking about the cylinder hone we did the hone is called a Brush Hone It's perfect for deburring and deglazing engine cylinder walls
its made just for Nikasil cylinders ....
Hey Brad quick question, whats your opinion on the idea thst this type of hone ruins the thin niksil coating? About to put my first top end on my 19 250 xc with 100 hours, cross hatching should be fine, would you recommend honing anyway to ensure proper ring seating?
@@davidjo997 ya if you have hone thats made for nikasil if not you can use green scotch bright pad and contact cleaner ..you want to get the carbon build up and deglazing the cylinder that will for sure help with new ring seating
Very awesome video, can you do a rm250 engine?
He has gold hands !
I was rebuilding my engine today slapped the top piece where those arms go up and down but it won’t turn over unless it’s off
Quick question for you. How many hours do you go before replacing crank on a 450?
Thanks in advance 🙏🙂
hmm.. i did mine on 120h, but it would be able to stay for more.. maybe 150-200.. depends.. but its better to do it before the damage happens
You don't check run-out on that hot rods crank out of the box?
Did u skim the head and cylinder block before installing it back?
No, buff and clean
Is it needed to use a hone for the cylinder when changing piston on a Sxf or other nicasiled cylinder? Or are there something else you can use that you have in your house?
check other comments, Brad (the mechanic) explains what he did... its not really a honing
Dirt N Iron thx Will do, did check a bit but not all way! Guess I was one of those lazy ones on the internet today! Haha. Great video and thx again for answering 👌
♥
What's the name of that last song? Good video just did my 2012 rmz 450. Thank you
sorry, dont remember
RMZ 250 FOREVER
i just got one too!
What was that part at 6.00 thank you

I hope you reply whats the best brand top end kit for a 18 yz450 or should i go oem
Vertex is good, thats what i always use
@@dirtniron thanks
I can't help but think 120 hours requiring a full top and bottom rebuild is crazy. I'd be doing one every 3 months.
Chicken Mac i have a 2015 yz250f with 316hrs. I’ve only put one top end in and replaced all valves w/ adjustments. I ride and race enduro, still going strong
@@victorcordova8338 yeah that's more like what I'd expect👍
it was still in decent shape, it would run longer for sure. Clutch was in worst shape but the top and bottom could do more. But since I am doing this build on the channel, it was a good time to go thru everything
@@dirtniron fair enough makes sense.
Here in brazil we put these 450 pistons on national motorcycles.generating around 55 hp.surpassing those imported on the tracks
cool!
Lovely from Tanzania 🇹🇿 would you help me to get some parts like block and Piston kit
do you guys have a shop I can send an engine to?
get in touch with @parapros in Instagram, thats Brad who did this engine
Everyone who was wondering the song name, it's Love and Fame by Consinity
Why don't 4-strokes have a small-end bearing?
How can I get in touch with brad? I have a 2015 RMZ 450 I want to get rebuilt.
What songs did you use at the end I can't find them .
sorry man, I dont remember, cant you do the search to find out ?

should be very similar
Hi could you please tell me what song that is at the end of the video
here you go th-cam.com/video/dBSFE-cNPVU/w-d-xo.html
How do you keep track of the bolts and screws

Did he check the ring end Gap or did I miss that. maybe lap the valves in or a valve job
yes is did check ring gap it was fast i didnt even see it ...and never lap in ti valves you would ruin them ..
Its case bye.little spriot. Can you weld
