$400 Yamaha Yz85 Top end Rebuild...IT RUNS!!!

[@cbrzach6002]

First time I ever seen a rebuild without taking the seat off

[@tejdz1337]

these bikes u can take out the entier engine without taking a single piece of plastic off lol

[@jameshatfield6814]

Wtf is up with people honing plated cylinders??

[@endurogoons2735]

Nice video Highgear!! The only thing I would recommend for next time would be to not let the bike idle to break it it. When you do that. You starve the cylinder of oil so its not the best for two strokes. You're supposed the varie the revs up and down for a while because it allows the cylinder and rings to heat up, expand, then cool back down. This is what breaks in the top end. Not a huge deal but just something to keep in mind for next time. Keep up the videos!

[@Tbands707]

I like the way you explained everything on installing a new top end. Others make it seem so complicated. 👌👍

[@thomashunter2159]

Because it’s not done properly icy t

[@michaelholden8667]

I got a Yamaha yz 85 built too a 112ccsuper mini it's fast ass he'll even got a pro lite piston kit by Wisco with all the goodies has a chm racing head that comes with2 head's one mx head and one school head mine is in gold you can get them in different colors gives you more compression well worth the 400 dollars I have in the heads along it can run on 110 racing gas hope you enjoy your yz there fast as hell

[@braptasticfilms3791]

My yz runs mint and the powerband is so snappy and quick it takes off like a rocket

[@michaelholden8667]

There great bikes I have one myself 2006 yz 85 fast as hell keep the good work up great video looking forward too more of your videos

[@JourdonGulick]

Those things look pretty fresh with the black rims.

[@High.Gear.Garage]

They do bro 🤘🔥

[@durangojohn714]

Thank you sooo much i needed to watch this for my kx80

[@High.Gear.Garage]

No problem man 🤘

[@jacksonshellhaas5891]

You tapped that plastic bag of gaskets and o rings 30 Times.

[@mudpine2535]

jackson shellhaas i was justing thinking that...

[@jacksonshellhaas5891]

mudpine ikr

[@High.Gear.Garage]

I laughed 30 times reading this while I wasn’t editing it I was wtf 😂

[@jacksonshellhaas5891]

Highgear MX yea I was like when is he going to stop...😂

[@matthewcracut7836]

That was Fast not even a week and the piston was delivered and installed good work man

[@rowdysworld22]

Nice man, I’m working on my 03 YZ85 I bought cheap that’s been sitting outside for a while

[@sarahgoldsack5166]

Tbh it doesn’t matter how you ride it in etc my mate done a top end rebuild he started it up ran it for 5 then started ripping it up on it and guess what nothing happens been running like a dream from then hahah from Australia btw

[@trickyclimax3459]

I think you need to add more oil to your mix, that thing doesn’t seem to be smokin’ enough. They call them 2 smokers for a reason ;) 40:1 or 38:1 is usually the best ratio to be mixing at.

[@nickcarter714]

TrickyClimax I run 32:1 in cr 250..

[@TAOMMANN]

Keep working hard brother. You’ll be rich soon.

[@dirt-rippers1018]

after you sell this bike buy a hawk tool kit and put your money into your yz250

[@OhhSooQuiikk]

Piston is on backwards! Arrow on the top should point towards exhaust ports

[@High.Gear.Garage]

Yes I put it on at first I fixed it

[@OhhSooQuiikk]

Oh good!! Didn't want you to blow it up want to see you rip it real bad!

[@baileybarrett2778]

I think you did a great job man 👍 I love these kind of videos and who ever says you did it wrong don’t believe them it even started up first kick that’s rare lol it’s definitely mintttt👌👌👌👌 race it against you 250 since it’s low on compression keep on keepin on brother

[@82notchback]

Correct me if I'm wrong but I'm sure those 2 holes in ur piston is supposed to go on the exhaust side!?

[@connerfleury7]

You are correct. Alot of things that made me cringe watching this. He better sell this bike fast cause that top end is not long to this world

[@High.Gear.Garage]

Yeah the arrow points to the exhaust side I had it backwards at first but i flipped it around

[@82notchback]

Highgear MX I've never rebuilt one and I know that those 2 holes go on the exhaust side. Buy a owner's manual to help yourself out boss. Save time and money

[@thomashunter2159]

Honestly feel sorry for who buys the bike next... didn’t measure bore diameter for piston and rings didn’t check piston ring gap🙄 few others could be list as well...hmm I guess you gotta learn but geez don’t do it dodgy

[@thomashunter2159]

Oh to add to it the break in period 🤦🏽‍♀️

[@highgear2685]

I can tell you've gained knowledge since the last build!

[@manuelquinonez6505]

Did you check air filter to see if it was dirty?

[@mrstk8985]

my yz85 justs top running the other day i went to store to fill up after i filled up and mixed the gas the bike started idleing high then died

[@johniewok]

I think you should keep this one 🗣 make it a big a wheel and let it rip

[@landonpiper9072]

Vids are awesome we should ride one of these days

[@Mxgarage33]

Anyone else notice he put the piston on backwards 😂

[@Mtb92740]

I was just about to say that, I was looking to see if anyone saw

[@High.Gear.Garage]

She’s mint

[@sy.busy_8613]

When you honed the cylinder did you have to put a bigger piston or did you put a stock bore piston

[@jeremyf9074]

I was hoping that he would loose the circlips in the grass.

[@tommybiggers8496]

Damn grass.

[@mikecal516]

How hard is it to do a top end rebuild? I think my yz85 is low on compression and it will be my first time doing it. What was your compression on your old piston

[@ACP336]

How do I know what kind of piston to get? And where do I get it from?

[@freerfixedit]

watching you put the head down on cement gasket side down hurt a little lol

[@ryderpowell1361]

Yo were my heart at?

[@ryderpowell1361]

Were do u live?

[@michaelholden8667]

Were did you buy your top end kit for your yz 85 complete top end Wisco piston kit doomed style with more compression with gaskets complete could you please tell me the company too order it from I would appreciate it Mike holden out of North Carolina said that

[@roostmx]

That 8 bro 🤭 i didnt know bro. Remind me

[@games4realepictiger345]

What u just did would take my dad about6 years

[@thomashunter2159]

He probably does it properly unlike old mate

[@speedokoterefinishnetwork4937]

Good video

[@bhunt6199]

Hello, my yz85 is leaking transmission oil out of the little breather hole under the water pump. Do you know what would cause this? thank you

[@blazbencic5453]

Why dont you ever have like a wooden or metal plate under the bike....you should put all the parts on it and prevent to loose them or get them dirty

[@jeremyf9074]

Nah, just throw everything down on the ground right? *facepalm*

[@blazbencic5453]

Snék i always have a metal plate, so i dont get my floot dirty and i dont loose the parts, or get them dirty

[@dirtbikemaster8057]

I just rebuild the top end in my 85 only took 1 hour

[@motorbikeryda883]

Bike runs nice man

[@High.Gear.Garage]

Thanks man really appreciate it

[@Hasangurbiyikli]

I have a 2002 yz 85 but i use for trainning my normal bike yz125

[@nolanryan1075]

You cant hone the cylinder like that you need to get a ball flex hone its not as much stress on the nikaseal cylinder

[@dangerdylan5005]

No one listen to this guy flat or ball you should never hone a plated cylinder. Wtf is wrong w yall

[@ericmurrell723]

Wouldnt the head be warped not scored?

[@JTRAMMZ]

Great Videos 🔥🔥

[@dirt-rippers1018]

go with vertex

[@troybursey8774]

Thing runs mint🔥👍🏼

[@extraclan_._4187]

Do u still have this bike and or u trying to sale it

[@simply_instrumental]

Is that a Big Wheel 85?

[@BMBradyy]

No hate but the money you spend on used bikes you could have afforded a brand new one

[@austintaylor2251]

DirtbikeBoyz buys to flip i do the same thing buy a cheap bike make a good profit

[@BMBradyy]

I feel like I get more outta my bike than a used one I used to have an 07 yz now I have a 16 rm that was a leftover and is about 4 months old I feel like it is worth the purchase compared to buying a used bike and having lots of problems

[@BOSS-jx8uq]

DirtbikeBoyz he buys used bikes for a good price and then sells it for more than he paid for, ofc he can buy a new bike but thats not the point. U wanna make profit, he already has his own private bikes that he doesnt sell

[@High.Gear.Garage]

Right!!!

[@shanedecourcey1223]

That’s the worst thing ye can do when breaking in a engine never let them idle that why the blow up quicker your ment to drive them slowly and go through the gears for about two three tanks then ye can’t start letting it out into power band

[@zacklataille342]

Nice man

[@Giant2020creepin]

Good job #Happy4thbraap

[@Fe3rnn]

Link for the kit?

[@SoLaRpLeXis03]

Good bike 2t i got a 2001 rm 80

[@ethanieldelatorre242]

Your piston is backwards just wanted to say it will run but Not for long

[@High.Gear.Garage]

I switched it before I put it back together thanks tho

[@cameronduckworth150]

How much would you sell it for

[@austinbirchall3857]

Does it have coolent

[@games4realepictiger345]

Austin Birchall yes

[@austinbirchall3857]

Hey highgear mx just wanted to let you know I love the channel I’ve been watching since the rm85 well that being said just good luck your channel will be very big if you keep it up 👍🏻

[@kyletaylor8619]

Austin Birchall better yet it has water hose water in it 😂🤣

[@highgear2685]

No coolant. Could radiator be leaking?

[@joshmx7161]

The yz85 is the easiest bike to rebuild ever. I can put a whole new topend in one of those in like 10 minutes.

[@High.Gear.Garage]

2stroke are easy I could’ve too but me having to set the camera every 5 min is hard and takes all day

[@joshmx7161]

yea

[@jadeniverson2800]

Maybe check before you ride

[@dylanlowlow9621]

What year ur bike bro

[@dirtbike434]

100mph thats the worlds fastest yz85

[@connerhooper2083]

Can’t believe you dropped that poor piston

[@zacklataille342]

Please put vertex in yz250

[@braptasticfilms3791]

Don’t get me wrong tho you did good for your second time I seems like a lot a first but after your first time it is easy and I wanna see it run because I wanna see if it’s anywhere close to being as fast as my Yz85

[@zacharyjoiner6089]

👌

[@kaycirothel]

What tires are those

[@rpmjunky2795]

Why rebuild this pile instead of yz250??

[@atvlifefam2424]

Blaster528 why be a bitch

[@rpmjunky2795]

ryan truth 1 It was a simple question. Have a snickers, u get hostile when your hungry

[@trickyclimax3459]

Blaster528 you’re*

[@dirt-rippers1018]

that's what I'm saying

[@rpmjunky2795]

TrickyClimax Ty grammar nazi

[@jonnyweston504]

Is it roght dere ?

[@mx_diederick8092]

Looks clean too👍

[@High.Gear.Garage]

Thanks man insane little bike

[@mx_diederick8092]

Highgear MX i said that because i got an yz 85 small wheel and i also got the bigger wheel one

[@mx_diederick8092]

Highgear MX and they look less clean that bike now i want black wheels too 😩

[@drewdog8346]

fucking great video

[@karenmook2073]

How much do u won’t for it

[@cobymorgan5314]

I think you put the piston on the wrong way

[@dirtbiker6624]

There’s a bottle of antifreeze in front of the bike

[@lmohr4630]

Time for new camera

[@High.Gear.Garage]

Why is that my camera is brand new and is good quality

[@DirtbikeNb]

Idle for 20 minutes? What the fuuuuuckkkkk???

[@High.Gear.Garage]

Thats how I break it in you can’t just hop on and start ripping

[@High.Gear.Garage]

Yeah that’s what I usually do after i let it idle just to be extra safe you know cause if I just installed the piston and I get on it and ride the c-clips or anything could fall out or anything and it would make it x10 worse if I was riding it and that happen so i just take the extra steps to be sure

[@DirtbikeNb]

Na man it can overheat bc the radiators have no airflow. You'd need to put a large fan in front of the bike to be safe. But I let my bikes idle for like 5 min with some small revs. Turn off let cool. Then ride it for 10-15 min no power and just cruise, let cool down then ride and slowly start going higher in the revs

[@thomashunter2159]

Exactly what your meant to do not let idle for 20 mins good way to cook ya head lol

[@dirtbikemaster8057]

Dirtbike N00b 69 I was thinking the thing because wen you let it idle for a long time the oil dose not burn probably and starts to clog up the head+no air flow into the radiators which can make it over head he might as well run no coolent

[@thomashunter2159]

Good video but please don’t talk

[@wesleyrabun6237]

Ya you no it’s the truth

[@kaigreenwood4033]

He put the pressure wrong in backwards

[@juliusgomez3432]

You have the piston on the wrong way

[@NTRGFX]

Why does he keep honing nikasil coated cylinders, talk about fucking a cylinder lol.

[@Rock-yi9cp]

The piston is on backwards

[@High.Gear.Garage]

I put it on backwards at first but I changed it

[@joeorourke4242]

you need to have some better camera skills, not hating, I just know your videos would be more enjoyable and informative if you pointed at what you are talking about.

[@its_just_me7057]

it's called a wrist pin!

[@High.Gear.Garage]

🤘

[@blantonroberson2972]

But good job

[@blantonroberson2972]

There isn’t a really a break in on a top end

[@trickyclimax3459]

EdgeWaterFishing yes there is. The ring has to seat properly in the cylinder otherwise it will seize the ring.

[@Spinnahemi345]

Yo

[@isaijimenez4109]

This dudes workshop it sketchy he puts the cylinder head on the concrete sketch

[@santanastarr1265]

Idle for 20 mintues☠😂😂😂😂😂

[@High.Gear.Garage]

I don’t get what so funny a break in is a break in don’t matter how you do it

[@santanastarr1265]

Highgear MX twostokes r not meant to idle .run the heat cycles .however u want but i wouldnt .do heat cycles at a idle

[@High.Gear.Garage]

That’s you bro there’s not just one way to do everything like you people think everyone has there ways

[@santanastarr1265]

Highgear MX w.e u say kids own a bike for for a year or two now they know everything .wut it looks like to me .. goodluck peace

[@ktm_braapbraap9719]

Why do we amateur riders worry so much about break inns on fresh rebuilds ,when pros ride at 100% open throttle on a fresh rebuild almost every race . Oh yeah they ain't gotta pay for there parts like we do . So yeah break that thing inn.

[@brandenochoa2793]

That’s what happend to me

[@jongglerdaring8260]

Wheres all the white smoke ? Somthing is fucked up here ... u done fuked somthing up on ur bike boy

[@farmjobtv4398]

Fucking lucky to be worth 400 bucks and why the fuck would you spend money on an old 85 it's not a pitbike and your way to big for it, what's the point

[@High.Gear.Garage]

It’s called making money which I can tell you know nothing about and why you gotta cuss every other word chill out mate sorry my videos make you so mad quit watching them then if you’re ass if gonna get hurt everytime 😂

[@farmjobtv4398]

Highgear MX what the fuck does cuss mean you yanky fuck

[@badboycards5334]

Honing a nickel plated cylinder is 👎 bad

[@isaijimenez4109]

That thing is fucking rigged

[@games4realepictiger345]

Get a 1980 Honda cr80

[@braptasticfilms3791]

Lol dude calm down like you said don’t waste your time on us and I would try to rebuild and make a video but I have built many motors and have a job at a dirt bike shop so I don’t think I need to grow up lol maybe you should grow up and get a good job and make some good money instead of this you tube thing

[@High.Gear.Garage]

Yeah maybe so maybe I do need to get a good job so I can have a yz85 as nice as yours

[@braptasticfilms3791]

Highgear MX and what kind of oil do you run and what mixture

[@braptasticfilms3791]

I didnt finish high school

[@braptasticfilms3791]

And the kids that haven’t built motor or anything can keep your mouth shut like y’all backyard “mechanic” probably don’t even use a torque wrench
