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

Wtf is up with people honing plated cylinders??

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

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

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

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

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

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

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

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

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!

Great Videos 🔥🔥

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

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

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

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

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

Vids are awesome we should ride one of these days

Bike runs nice man

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

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

Wouldnt the head be warped not scored?

Nice man

Good video

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

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

Link for the kit?

Those things look pretty fresh with the black rims.

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

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

What tires are those

How much would you sell it for

That 8 bro 🤭 i didnt know bro. Remind me

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

How much do u won’t for it

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

Is it roght dere ?

What year ur bike bro

Is that a Big Wheel 85?

Good bike 2t i got a 2001 rm 80

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.

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

Good job #Happy4thbraap

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

Anyone else notice he put the piston on backwards 😂

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

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

Thing runs mint🔥👍🏼

Please put vertex in yz250

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

Yo were my heart at?

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

What u just did would take my dad about6 years

go with vertex

But good job

fucking great video

👌

Does it have coolent

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

Ya you no it’s the truth

Maybe check before you ride

Looks clean too👍

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

Yo

No coolant. Could radiator be leaking?

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

Can’t believe you dropped that poor piston

It’s blue lol

Second

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

I think you put the piston on the wrong way

Time for new camera

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

Why rebuild this pile instead of yz250??

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

That’s what happend to me

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

100mph thats the worlds fastest yz85

Idle for 20 minutes? What the fuuuuuckkkkk???

You have the piston on the wrong way

The piston is on backwards

Good video but please don’t talk

He put the pressure wrong in backwards

Why can't I find these deals in PA?

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

it's called a wrist pin!

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

You sure you didn’t snort a line you jumpy

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.

Idle for 20 mintues☠😂😂😂😂😂

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

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

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

Get a 1980 Honda cr80

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

Honing a nickel plated cylinder is 👎 bad

That thing is fucking rigged

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

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
