YZ85 Bottom end Rebuild

- Today we're rebuilding the bottom end on my 2002 Yz85, This was my first splitting cases on a dirtbike so I was kind of hesitant on doing so, but everything went perfect and if you did enjoy this video please give it a like and consider subscribing.
To all those who feel need to tell me how I don't know how rebuild motors. I get it the "techniques" used in this video are all wrong but hey I was 12-13 these were filmed 3-5 years ago depending on the video (uploaded a year or two ago) I can assure you that no motor after this (besides the other two motor rebuilds on the the channel) was built like this. I just glad I was motivated to try this because here I am years later I've seen over a thousand customers and have flipped a 1-2 hundred bikes and happy I did it. This motor ran for years same as the other motor rebuilds until I sold it so I guess I got lucky.
Love that you did this shit, fuck the haters.
Hamfisting "rebuilds" and then selling them off before they blow up is a great business plan. There's a sucker born every minute!
Bro ur like me bro like I rebuilt my dirt bike I hit it with the hammer but I hit the out side of bearing people are stupid keep it up it won’t damage it
Hope it works out im bout to rebuild one!!
My 1st rebuild wasn't much smoother but hey I was 10 and it was a 1974 yamaha gt80. That motor ran fine the 2 years I had it after. Long as it goes together right the process doesn't mean shit
Best video ever! “If it starts , that’s cos I’m a master mechanic” 😂. Great video from a young fella 👍
What the fuck is he doing to the crank bearings?!
WTF thats amazing😂
Bro i didn't hammer on the inner race!!
@@TheCompound1325
Please just look at 10:05 to 10:10 thats brutal😂
@@hinterhoftuning324 Dude I was there and I know what it looked like but trust me you don't know what actually happened. I know I did it wrong but I can't go back so.....
Edit: I thought it was a different of the video and I know I'm retarded for doing that.
Rebuild one now on Murray mini motor!
how do you take the clutch off without a special tool?
Holy shit dude, what are you doing with that hammer!!!
Chill bro! I know you're not supposed to use a hammer but i did hammer on the outside edge regardless it wouldn't cause any problems problems anyway.
Kicking ass brother keep up the good work
Hey I was working on my yz85 2009 engine and I have 4 tiny treaded black thing it not a bolt but I have no clue where it goes can you help?
I don't quite know what you're talking about if you could describe it be better if I can help you.
Moto Repair i found out they go on the extra weight for the fly wheel
When I try to take the primary gear off the nut is off but the gear won’t pull off do you know why it won’t ?
Get a gear puller on there. Should come right off some guys put Loctite to hold their gears in place
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
Unless you're doing lots of wheelies or there's too much oil in the transmission it shouldn't leak but there's also the unlikely case that you're having the crankcase leak high pressure into the transmission.
mississippi proud thank you, yah I thought that was the problem, I just ordered them because I took is apart and one of them was mangled
That weep hole is there so when coolant and or oil leak out you know it's time to replace the seals and bearing for the water pump
How to know if crank is seized?
The bike won't kick/turn over
@@TheCompound1325 how would you know its not the piston
@@L3thal69 there's really no way to know until you open up the motor you can start by just taking the head off and see if there's any piston damage
you done fucked up son
Pays 200 dollars first thing he shows is (stickers ) how did u get the bearings out
I used the case splitter to push the bearings out
How long did it take you
I was gonna rebuild mine but paying it get it put in
@@randomreviews563 I think around 4-5 hours
hi just a question... is there a washer that goes on the end of the kickstarter shaft, just where shaft sits into the case @ 5.50
No
how much to do my 85.?
200 + cost of parts. refer to my pinned comment at the top of the comment section because I know this video is riddled with mistakes.
Hey man can you link a crank puller that’ll work on mine it’s a yz80 2001 and a cheap on thanks!!! From amazon
Time to buy new a bearing......
Yo I know bro you supposed to use a socket but the best thing I had was a hammer working around the outside of the bearing I'm not dumb enough to mash on the very middle of the bearing.
Moto Repair nah ur supposed to heat up the cases in a bbq or something and freeze the bearings overnight in the freezer and the bearings will literally drop right in
@@Clouderrr Exactly what I did my dude
Moto Repair bro u hammered them in lol
@@ClouderrrYeah I know but it ran perfect I understand that did it wrong but it worked so 🤷 it doesn't matter now
Hey bro would you know the torque spec of the boss but on top of the clutch basket. This would really help thank you
Title should read 'how not to install main bearings'
Great idea!! I'll keep that in mind for the next video title😊
Lmao wow
Do you know the exact specs on that engine? I'm about to break open mine to replace the kick start but its a yz80. Not really sure there is much difference besides less hammer.
Lmao you see him hit brarings with hammer and you ask him does he know engine specs lmao too funny bro
Bigger hammer an more heat
He loves that hammer
When he hit the Bering with the metal hammer 😬
Hahaha
If he it’s the sides I mean I do it with a flat wood brick it don’t damage jt
never push bearings from the inside.. press on the outer part
Man really should have zoomed in on that part cause i guarantee I didn't touch the middle.
@10:07 IS WHY I NEVER BUY A FRESH REBUILT never hammer inner race
Gosh dang just because i didn't use a socket doesn't mean i hammered on the inner race!!
Sorry I'm not getting on your case but when I saw this I had a reaction like when you hit a rock with a lawn mower it looked bad from my eyes. Rock on bud but I still dont trust any one with a 2k motor I'm buying
Bro you literally set the screwdriver in the middle race and hammered it lol
Solo falta la practica de eliminar el martillo...saludos
Should have lubricated the bearings
I oiled every bearing during reassembly.
The bearings you installed were installed incorrectly. You are supposed to hit the outer part of the bearing with a socket not the inside.
I'm highly aware that you're not supposed to be hammering on the inner race and I know it looks like I'm hammering on the inside race but I was actually working my way around the outside race
thats also incorrect,no hammering is required at all,stick bearings in the freezer over night then heat up the crankcase where the bearing fits using mapp gas or similiar then the bearing drops in,same with crank in freezer then heat centre of bearing just a little,crank drops straight in too -repeat
It would not cost a 10 spot to have a shop press them in
Wtf! Who told you to smash away on bearings like that!?
Bloody he’ll all wrong
Poor lil engine. 🤦🏻♂️
Yeah it blew up not even 10mins after the rebuild. I have no idea what the hell I'm doing 🤦🤦 such an idiot. I should be working in bikes any more.
Don't run it so hard dead after rebuild
I let it warm up for a few minutes and that's a good enough break in for me but to each their own.
hahahaha
how do you take the clutch off without a special tool?
