BeRAD I LOVE your stuff

[@joshinaround966]

BeRAD you should put a fmf gnarly pipe on the 250

[@petertaylor3424]

rather easy to inspect a 2 stroke via the exhaust port before pulling the whole thing down.

[@LCP1988]

Peter Taylor or a simple compression test will tell the story

[@LCP1988]

And don't mean to be a keyboard warrior but if your just doing a piston change you don't actually have to take the head off, just save you a step and some time

[@BLDH]

Respect for doing a rebuild in a cast

[@joshpodolsky7740]

My brother and I laughed so hard at your Swedish police video! We could just see the awkwardness.

[@dalma8593]

BLDH SQUAD REPRESENT!!

[@BeRADMoto]

So I kinda just did this for fun/boredom. I wanted to see how things looked inside after about 50 hours. Now I know it'll be good for another 150+ with ease. Also, if I have to rebuild it in my van van while traveling, it will be much easier now that I know how to do it all!

[@imdestructive7624]

In your van van?

[@_radical_rider_2226]

BeRAD sick stuff

[@warwiener]

I have old 250 ktm and it has nice habit of dropping piston skirt in the block between 50 to 80 hours did that 3 times whit forget piston so is started to replacing piston every 50 hours it is a lot easier and cheaper switch piston than replace bearings, rod and balance it every time. but even that does not help if you forget to switch jet and go flat out -30c temp got nice hole i my piston and rod is nice and blue about half way down

[@Dalebrah69]

that's no rebuild it's a piston change

[@imdestructive7624]

When you take something apart and put it back together, its called, "Rebuild" It doesnt matter if you replace shit or not.

[@modsquad1670]

Cringing as he takes the c clip out of and doesn't have a rag in the bottom end

[@motofaija]

was sure hes gon drop that clip inside the bottom end :D

[@Factory928AC]

I feelzzz

[@thicok4555]

Smaeeeeeer

[@Rekonmoottorihiomo]

@@motofaija moi

[@chadanderson2486]

Should have been riding instead of taking it apart. I love my YZ's. They will run forever if maintained properly.

[@coleeitel4861]

helpful tip put some rags around the connecting rod so you dont drop anything down the bottom end

[@VroomVroomDana]

Hell yeah man good shit! I am at 70+ on my YZ so I think I will wait it out a little. Maybe like 125-150

[@MadeofSpareParts24]

[@ak47man2002]

[@alexandergammill1366]

Neat Dude! I just acquired and rebuilt a 1999 YZ 250, my first! It's very interesting to see the similarities with my old beater and a newer nice ride! Thanks for sharing!

[@threefiddyone]

You forgot to put your power band on

[@mareksumguy1887]

Yeah i noticed that too.

[@billyliddy5833]

i think i saw him put the yellow powerband in. personally i like the blue powerband as it produces extreme top end power but still has enough low to mid range punch to giddy up when you need it. my mate put on two powerbands but only got an extra 50% more grunt.

[@markheron6612]

billy liddy yeah I like the blue yellow mixed power band go really go with no 2 Stoke oil

[@tanneranderson729]

I think I saw him put the yellow powerband on personally I like the “no powerband” one because it produces no power

[@megawhip1]

why on gods great green earth would you take apart a motor and not replace the top end??? and you cant re use circlips

[@lenny-pm6he]

At least replace the rings

[@marlinrobertson5464]

ALWAYS have a rag covering the crank so that no dust or dirt can get in

[@BeRADMoto]

Marlin Robertson yeah I should have while putting the cylinder on...I think it was alright though.

[@marlinrobertson5464]

Generally it is but with an mx bike some dirt can get down there and splitting cases is not fun lol

[@Tikkikoira]

You are right but usually the rag is for piston circlip not falling in the crank...

[@marlinrobertson5464]

I have seen both happen but often dirt is harder to remove because you cannot pick it up with tweezers or a magnet

[@cameron5454]

+Marlin Robertson I had to learn that the hard way, my brother and his friend we're taking apart my top end to check it, and my brothers friend dropped the circlip down the bottom endXD!

[@Georg1606]

even if you've worked on bikes for 20+ years it's impossible not to spill coolant

[@BeRADMoto]

hahahaha truuuueeee

[@vahvahybrid3243]

hardest thing doing rebuild is trying to not spill it everywhere :D

[@btech581]

and here i am, thinking im just a slob..

[@mrdiddlesofficial8724]

Are you adding a stroke? Should give it more power. Did you add a BeRad sticker to the piston before reassembling? That'll add like 5 horsepower, so I've been told...

[@tanneranderson729]

Bruh why you do him dirty like that, this man would actually believe you and do it😂

[@sqhunter65]

I don't know man when I take them apart I always put new rings in they're cheap

[@codyz199]

Instead of takin off that carb boot, I take out the two bottom bolts of the subframe and lift it swing it up. Also you don't have to take off the shrouds you can just undo the bottom bolt from the rad on both sides and just take the whole tank and shrouds off in one piece. Just a suggestion if you're in a time crunch and want to save a little bit of time.

[@harrynichols4707]

I was cringing so hard when he rawdogged that cir clip!! Would have been a fun time splitting the cases hahaha

[@ArrowTrajectory]

Regarding carbon build-up; we add a little (about 1/4 cup) of carb/injector cleaner (or Sea-Foam) to each batch of premix. Keeps the piston & power valve super clean.

[@quirinm.]

Good way to wash the oil of the rotating parts 😂

[@jazmeireo302]

def. one of the better Rebuild videos I've watched. Good detail and editing! 2 strokes look pretty simple compared to the 4 strokes I am used to.

[@SuperKxtreme]

No left over screws? Wish I could do that xD

[@DannyBrown04]

Best way to put the piston and rings in the head is do it before hand but don't put it all the way in and then connect the piston to the rod! saves you from pissing around with a connected piston and squishing the rings in a tight area @7:50

[@BeRADMoto]

Daniel Brown ahhh yes! Next time I'll try that thanks!

[@Shadow0fd3ath24]

Daniel Brown Till it falls out 3 times and you get tired of it lol

[@Georg1606]

you should put a rag down the crankcase so you don't drop your piston clips and other shit down there, because if you do you have a LOT of work to get it out

[@BeRADMoto]

that would have been a good idea! Luckily we did it without dropping anything haha

[@ultimatefriikki]

BeRAD yeah, we took my friends mopeds top end apart yeaes ago, and the clip went down, and then the upper rod bearing fell apart and all the damn bearing pieces fell down too. We had to take the whole thing off and shake it upside down :Dd

[@wymanlovestkd]

Georg1606 I dropped a piece of gasket and a piston clips down the crank it was so much trouble to get out

[@nickchilds3104]

On my WR I dropped the valve shim down the head TWICE! Was able to get it out with a magnet but man was that scary.

[@Georg1606]

it's scary as hell

[@LockStockNBarrel]

Leave your radiator cap on when you take your drain bolt out and you wont have coolant flying everywhere before you can get the bolt out and bucket in place. Once its out and you have your bucket in place crack the rad cap and it'll drain. It's physics!

[@coleeitel4861]

ive rebuilt many dirt bikes over the years a helpful tip is to put some rags or shop towel around the connecting rod so you dont drop anything down into the bottom end! but great job!!!! keep up the videos

[@MichiganManiak]

make sure to check the power valve assembly. They are notorious for those little screws coming loose on the main shaft that operates the power valves.

[@MichiganManiak]

Also check the fuel cutoff solenoid in the carburator. There is a small rubber plug on the end of it that deteriorates and it is super prone to failure.

[@ryanbeers5628]

couldn't of said it better Kendall that was smooth at the end bt BERAD iy yi yi

[@ninobluekens]

1:05 Just taking a shit😂

[@Bassalicious]

I have to say I'm impressed. This is how it's done! Great job considering it was your first time doing it. Although I see you had some help along the way. ;) I really hope you used new cir clips for the wrist pin though. These things really stop being safe when you reuse them.

[@rigguyjt]

Also making sure clips are either in 12 o clock or six o clock position so they don't compress and pop out with centrifugal force.

[@blazbencic5453]

Love the video!! Nice work "mechanic".

[@xboxdude7647]

I may be wrong but I was always taught that putting used rings back into a cylinder was asking for trouble. Enjoyed watching the video, way to go with a cast

[@alessandrocasadei147]

if i can give you 2 simple tips and tricks, when you're removing pistonseeger put something in the hole of the engine, if seeger fall in there its finished, when you wash your exhaust use gas, non water ;) i hope you appreciate it sorry foto the english i' m an italian boy!

[@KruznwithKMAN]

At that point you might as well thrown a new piston and rings in it?

[@aros007z]

Nice!

[@mitsu554]

The same piston and rings?

[@eamh2002]

Nice, its been running rich but thats a good thing :) When the carbon is baked on the piston and brown its more towards lean. Some people dont know that rich tends to make the piston crown cleaner and lean mixture bakes everything on it :p

[@camshaft1840]

When I got my cast off from when I broke my wrist October 1st. I had half the grip strength. and prolly 30% less bicep strength. Have fun...

[@Izreal3345]

Damn dude that went pretty smooth I wish my jobs can go like that when I have to do work on my bike lol

[@IdkIdk-nk2gv]

Love seeing you work on it

[@minimonkey969]

u just earned yourself a like for that clip on the toilet

[@motomax13]

Nice buddy. Preventative maintenance is key

[@__Leon__]

yoooooooooooo i like your video's man

[@46offroadrider]

Predictive is better, but preventative is better than nothing at least. And it's always good for peace of mind to check her out on the inside.

[@meganfitzgerald651]

Nice video, best thing about two strokes is they're super easy to rebuild!

[@Keemo577]

Are you from the midwest? Looks like midwest scenery and makes me miss it.

[@Timzy7]

Did you reuse your head gaskets and base gasket? I've heard they'll still be ok if you put them in the freezer over night, curious Thanks!

[@shadetreesurgeon]

Whaaaat no big bore kit? ;)

[@kingmatthews5436]

Nice you take really good care of your stuff

[@thecyclemedic8424]

Always use OEM pistons in your Yamahas. They are best. Also doing a new piston and rings at 50 hours is good insurance that the bike will not blow a top end. It's cheap insurance . Cool video

[@chadanderson2486]

50 hours!!!! What a waste of time and money. And then reuse the most important thing!!! New circlips!!!! Dumb. My YZ's have been bulletproof for 20 years. I can hear when they need a top end and it ain't that often.

[@NOTHERN_SINGLETRAK]

Hey.. what do you use for pre mix ? what ratio are you mixing at ? looks super clean in that top end

[@rc7175]

Just a hint!! put a rag around your rod and bottom end when pulling circlips out of the piston. If one of them fall into the bottom end you will be spending big dollars to split the engine to recover the clip. A simple solution!

[@pierrat1]

Did you put a new piston in or just clean the little carbon build up that was on there?

[@michaelthomas788]

FYI running to Rich plug should be Brown ish red if jets are correct

[@carrothead8462]

Rooki move no rag in the bottom end while taking wrist pin out and with plyers like that

[@nemanjadraca4012]

I remember my first 2 stroke I rebuilt I took the Trany apart not know how it all went back with the washers and forks that was a pain.

[@ryy597]

what stuff did you use to get the carbon off the head? tou used a toothbrush with something?

[@melonwizard2040]

so, if i start with motorcycles, is this like a thing I'm gonna have to learn? cause this looks difficult

[@chrisGilbert25]

Melon Wizard lol I thought my self how to rebuild a bike when I was 12 it's easy just watch you tube

[@melonwizard2040]

gee thanks, unfortuanately, not all of us have the time or talent to just "self teach" building stuff like that

[@stevenpoirier8676]

What gas and oil ratio do you use? I use 32:1 and my spark plug buried out after only 3 rides.

[@RideWithTheWolf]

It seems like you would at least put new rings since you had it apart. Save the old rings for something else?

[@hondaguy425able]

Did you have to remove the power valve to remove the cylinder head?

[@dv8214]

hey any reason why you take the farings off the tank? I usually just undo it at the rad. I'm lazy lol

[@moshpitcircles6345]

Stuff a rag around the piston before removing the circlip.

[@daVidFonda]

Nice vid. But, I would put a cloth underneath the piston when getting the axle from the piston out and back on. Just to prevent getting the little ring falling into the engine.

[@colemadden7704]

TIP!!! when you take cylinder off and your taking piston off put rags in the bottom end incase you drop a clip in it or something

[@wymanlovestkd]

Do u know that coolant tastes good

[@rayosteen4339]

That looked really good for 50 hours. What oil and ratio do u run?

[@Mathiascsc]

Who's the man helping you?

[@MegaWolfman76]

I did a new top end on my 89 cr250r had it bored and sleeved and it is alot easier to rebuild it with the motor out

[@GarageMob]

"What can you hurt just taking things apart?" *Instantly remembers story about BeRad taking his first bike apart*

[@ODST993]

hopefully you didn't mess up the c clip for the piston.

[@ctk166x2]

now usually you're not supposed to ride it on the first heat cycle...I usually heat cycle it about three times before I even ride it you have to seat the rings and let the bike get adjusted

[@Belicose777]

Pretty risky pulling that clip off without placing something in the opening to the crankcase to catch it. Good job. With my lack I'd drop it and have to split my cases.

[@snowrider4495]

Did you say oil filter or air filter?

[@braddirago4774]

Hey Brad... What fuel tank do you have fitted to you bike. I'm looking for one for my YZ250X. That one doesn't look to ugly at the fill, I don't like the way some of them stick up. Cheers from OZ

[@justforlaughs8988]

you should be putting in evens waterless coolant look in to it man it's the best stuff out there!

[@junkyardhemi]

How'd you get that jet ski up there?

[@WujoCaZa]

Oh man,that yz needs a little bit jetting.And also put a rag in the cranckcase when are you pulling out the piston clips.You dont want to drop that in to cranckcase :D

[@davidnnn96]

how many hours/miles at the time of this "rebuild"?

[@EnduroEverlasting]

Good video! YZ250X is awesome!

[@RelentlessCo]

I wanna rebuild my 125 by myself. I'm just so confused about the power valve . Like what to do once I'm there .

[@szczepanski99]

2 strokes have oil filters? 0:04

[@squirtsomedirt3161]

Luke Szczepanski i think he said "an oiled filter" (air)

[@simtak6620]

Nice video , I do mine right now on my yz250x 2019 , what is the brand of your premix oil on the back ground and your mix ratio thanks !!:)

[@spencer1244]

You forgot to stuff the crankcase with rags! If anything like that clip shoots off in there you will have to split the cases!

[@maxwellyt9745]

your rebuilding a brand new bike?

[@wernersunkel]

Good job bro. i recently did the top end on my yz125. 👍👍

[@RelentlessCo]

Werner Sunkel hey man my yz125 needs a rebuild , what did you do once you got to the power valve ? Only part I'm confused about

[@brian62793]

Was still expecting him to pop a wheelie at the end there.

[@Keijo676]

How long you can drive with a piston in this bike?

[@skproductions59]

Do you think it's really worth it to have a two stroke to have to rebuild it every so much, is it really that much better than a 4 stroke. I'm really split between buying a yz250x and a yz250fx. I have started on a ttr-125 and loved it but when I rode a 2 stroke it was absolutely amazing but I have never ridden a 250 4 stroke, I'm only 15 and really don't want to worry about jetting the carb or rebuilding the engine, do any of you guys think it's really worth it to buy a 2 stroke or should I just get a 4 stroke.

[@LockStockNBarrel]

Two strokes are much less maintenance than four strokes. And a hell of a lot easier to do maintenance on as well. The misconception about two stroke and four stroke maintenance comes from people who are too lazy to do maintenance and just claim that four strokes require less, and their four stroke bikes are destined to kaboom after a certain amount of hours. It just lasts longer on no maintenance than a two stroke does. When you don't do maintenance on your two stroke you just loose power, forcing you to replace your piston / rings. Of course a smoker will kaboom if you let the piston slap around in there long enough too, but it'll be damn near un-ridable before then.

[@skproductions59]

Enduro NE thanks this really changed my mind

[@chrisGilbert25]

SeanKyle I would get a 125 or if you want a Ktm 150 they are plenty of power for a teen going with a 250 2 stroke is a lot of bike for a 15 year old coming from a trail bike

[@skproductions59]

I understand where your coming from but i'm a bigger kid for 15 i'm 5 foot 10 around 210 pounds, ive ridden many 2 stroke 250's and have really enjoyed the power on the bike the only thing is i have never ridden a 250 4 stroke so i don't even know how 4 stroke 250 feels like. Every person on a 250 2 stroke tells me to just get the 250 because i am aroud the size of almost a full grown man ad i will just grow out of a 125.

[@crashcross9965]

I know how it feels to not be able to ride I've just got my second surgery yesterday and I have to wait for another 3 weeks before I go back out 😥😥

[@JoshRips]

How did you make a yz250 street legal and how do I do it in NC

[@BeRADMoto]

it is street legal...i'll make a video on it

[@mino7122]

Who Cares it definitely can't be Street legal

[@nakkisampyla4460]

yes it can wtf

[@Fishifyed]

research

[@canadianunicorn8637]

I'm wondering what kind of camera you use when taking photos while your riding?

[@imlurkinass8925]

do u think a 250cc is to big for a 14 year old im 5"9 150lbs?

[@erniegdt]

im LuRKiNaSS listen kid, no one on the internet will be able to tell you if it's right for you. You got to go out and test ride one. If it's your first bike it's a definite no but if you have experience it just might be. A 250 two stroke can be a lot for some people so just test ride one.

[@imlurkinass8925]

erniegdt i have experience with fourwheelers like alot ... i have some experience with a 175cc dirtbike but i just don't know if im ready for a 250

[@rihs335]

so may haurs you get on bike ?

[@tanneranderson729]

Just cringing how they never put 2 stroke oil on the piston or cylinder when re installing😬

[@chadrides914]

Yeh me too. It’s like franks. I put that shit on everything.

[@aaronlong6975]

you put a piston in with rings always on a 2 stroke

[@johnhewitt1096]

No need to pull that motor apart with those low hours.

[@jpwrangler1]

I agree I like 30-50 hours for top ends on, you Can never do to much maintenance. I’ve always done my bike/truck maintenance early. I recently got rid of my 250 2 stroke and got a 13 Rmz 450 1 owner a buddy bought it new, he did amateur racing. The bike is great for a race bike but I ride 80%% trails. Had a fresh top and bottom end rebuild a $1000 full titanium fmf exhaust and a lot of other good parts. I can’t wait to sell it and get back on a 2 stroke.I wanted to give the 4 stroke thing a try and my biggest complains is no e start 4 strokes need e start and first gear is to tall for trail riding also overheats trail riding and I’ve put on over size radiators, silicone hoses running engine ice and a 1.8 radiator cap the only thing left to do is a boysen water pump and the last thing I wanna do is put a fan kit on It, I was raised on 2 strokes and just prefer them for the riding I do my 2 strokes overheated maybe 5 times if that in 20+ years and multiple bikes. Then when it comes time for a top end kit I can build a 2 stroke for $200 but let my 450 blow and first I’ve never built a 4 stroke race bike and second the parts are double or more. I’m just a 2 stroke guy, I need to come off the cash and get what i want, a ktm 300 like the factory guys rode in strait rhythm 👍
