Thanks for watching:)
First time I ever seen a rebuild without taking the seat off
these bikes u can take out the entier engine without taking a single piece of plastic off lol
Wtf is up with people honing plated cylinders??
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!
I like the way you explained everything on installing a new top end. Others make it seem so complicated. 👌👍
Because it’s not done properly icy t
Thank you sooo much i needed to watch this for my kx80
No problem man 🤘
You tapped that plastic bag of gaskets and o rings 30 Times.
jackson shellhaas i was justing thinking that...
mudpine ikr
I laughed 30 times reading this while I wasn’t editing it I was wtf 😂
Highgear MX yea I was like when is he going to stop...😂
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
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
Those things look pretty fresh with the black rims.
They do bro 🤘🔥
Anyone else notice he put the piston on backwards 😂
I was just about to say that, I was looking to see if anyone saw
She’s mint
My yz runs mint and the powerband is so snappy and quick it takes off like a rocket
That was Fast not even a week and the piston was delivered and installed good work man
Nice man, I’m working on my 03 YZ85 I bought cheap that’s been sitting outside for a while
Keep working hard brother. You’ll be rich soon.
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
Yo were my heart at?
Were do u live?
Piston is on backwards! Arrow on the top should point towards exhaust ports
Yes I put it on at first I fixed it
Oh good!! Didn't want you to blow it up want to see you rip it real bad!
What u just did would take my dad about6 years
He probably does it properly unlike old mate
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
after you sell this bike buy a hawk tool kit and put your money into your yz250
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.
TrickyClimax I run 32:1 in cr 250..
Correct me if I'm wrong but I'm sure those 2 holes in ur piston is supposed to go on the exhaust side!?
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
Yeah the arrow points to the exhaust side I had it backwards at first but i flipped it around
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
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
Oh to add to it the break in period 🤦🏽♀️
Good video
Vids are awesome we should ride one of these days
I can tell you've gained knowledge since the last build!
That 8 bro 🤭 i didnt know bro. Remind me
I was hoping that he would loose the circlips in the grass.
Damn grass.
I think you should keep this one 🗣 make it a big a wheel and let it rip
No hate but the money you spend on used bikes you could have afforded a brand new one
DirtbikeBoyz buys to flip i do the same thing buy a cheap bike make a good profit
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
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
Right!!!
Great Videos 🔥🔥
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
How do I know what kind of piston to get? And where do I get it from?
Bike runs nice man
Thanks man really appreciate it
You cant hone the cylinder like that you need to get a ball flex hone its not as much stress on the nikaseal cylinder
No one listen to this guy flat or ball you should never hone a plated cylinder. Wtf is wrong w yall
go with vertex
Did you check air filter to see if it was dirty?
watching you put the head down on cement gasket side down hurt a little lol
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
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
Nah, just throw everything down on the ground right? *facepalm*
Snék i always have a metal plate, so i dont get my floot dirty and i dont loose the parts, or get them dirty
Nice man
Maybe check before you ride
When you honed the cylinder did you have to put a bigger piston or did you put a stock bore piston
Your piston is backwards just wanted to say it will run but Not for long
I switched it before I put it back together thanks tho
Good job #Happy4thbraap
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
Why rebuild this pile instead of yz250??
Blaster528 why be a bitch
ryan truth 1 It was a simple question. Have a snickers, u get hostile when your hungry
Blaster528 you’re*
that's what I'm saying
TrickyClimax Ty grammar nazi
👌
Good video but please don’t talk
100mph thats the worlds fastest yz85
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
Thing runs mint🔥👍🏼
The yz85 is the easiest bike to rebuild ever. I can put a whole new topend in one of those in like 10 minutes.
2stroke are easy I could’ve too but me having to set the camera every 5 min is hard and takes all day
yea
No coolant. Could radiator be leaking?
I have a 2002 yz 85 but i use for trainning my normal bike yz125
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
fucking great video
Good bike 2t i got a 2001 rm 80
I just rebuild the top end in my 85 only took 1 hour
Can’t believe you dropped that poor piston
Ya you no it’s the truth
Does it have coolent
Austin Birchall yes
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 👍🏻
Austin Birchall better yet it has water hose water in it 😂🤣
Idle for 20 minutes? What the fuuuuuckkkkk???
Thats how I break it in you can’t just hop on and start ripping
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
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
Exactly what your meant to do not let idle for 20 mins good way to cook ya head lol
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
Looks clean too👍
Thanks man insane little bike
Highgear MX i said that because i got an yz 85 small wheel and i also got the bigger wheel one
Highgear MX and they look less clean that bike now i want black wheels too 😩
How much would you sell it for
He put the pressure wrong in backwards
Wouldnt the head be warped not scored?
Link for the kit?
Please put vertex in yz250
Time for new camera
Why is that my camera is brand new and is good quality
There’s a bottle of antifreeze in front of the bike
it's called a wrist pin!
🤘
I think you put the piston on the wrong way
Do u still have this bike and or u trying to sale it
But good job
Is that a Big Wheel 85?
That’s what happend to me
You have the piston on the wrong way
The piston is on backwards
I put it on backwards at first but I changed it
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
Second
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.
What tires are those
What year ur bike bro
How much do u won’t for it
Why does he keep honing nikasil coated cylinders, talk about fucking a cylinder lol.
Is it roght dere ?
It’s blue lol
Yo
This dudes workshop it sketchy he puts the cylinder head on the concrete sketch
There isn’t a really a break in on a top end
EdgeWaterFishing yes there is. The ring has to seat properly in the cylinder otherwise it will seize the ring.
Honing a nickel plated cylinder is 👎 bad
Wheres all the white smoke ? Somthing is fucked up here ... u done fuked somthing up on ur bike boy
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
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 😂
Highgear MX what the fuck does cuss mean you yanky fuck
You sure you didn’t snort a line you jumpy
Idle for 20 mintues☠😂😂😂😂😂
I don’t get what so funny a break in is a break in don’t matter how you do it
Highgear MX twostokes r not meant to idle .run the heat cycles .however u want but i wouldnt .do heat cycles at a idle
That’s you bro there’s not just one way to do everything like you people think everyone has there ways
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
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.
That thing is fucking rigged
Why can't I find these deals in PA?
The Ghost of the Flying Dutchman where in pa are u
brian gbody Northampton county
Get a 1980 Honda cr80
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
Yeah maybe so maybe I do need to get a good job so I can have a yz85 as nice as yours
Highgear MX and what kind of oil do you run and what mixture
I didnt finish high school
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
