Great video. Very entertaining. Great camera angles. Can i just suggest one thing. Get a dead blow hammer or a rubber mallet for removing your cylinder rather than a steel hammer.
At a pinch use a block of wood between the hammer and the thing you are 'persuading'. Also buy some individual sockets to fit things like the rear axle and stuff that you don't have, rather than using a pipe wrench.
The hole in your power valve linkage is for the dowel pin adjustment tool that is usually supplied when you buy the bike new. I still have mine but very easily lost over time in some case. It's just a small dowel rod about an inch and a quarter long.That's to make sure your valve is correctly aligned when ever it's disassembled. Adjustment procedure is in the shop manual.
Hey there i seen your comment that you still have your powervalve alinment tool do you still ha e the manual too if so can you send me a picture of the adjustment procedure i can find a manual anywhere near me
no he didn't, he said so but he did first the rear ones and then the front this whole series is something like "answer to: wtf the previous owner did to your bike"
Looking Good! I have done a rebuild on my 96 yz250, but the thing that set mine apart was that I changed all bolts! I recommend that you should do it aswell!
That part to the power valve that you were referring to is to hold the power valve arm in place while you tighten up the bolt that connects to the power valve. What it does is it prevents the acuator arm from being bent while it is being tightened up. I still have mine for my 05' YZ250. You can use an allen wrench as long as it is the correct size and fits. The torque setting is really low for this bolt. Hope this helps.
Hey dude, too late now but for future reference always make sure the piston circlips opening is straight up or straight down. With the speed the engine is moving at its possible that the clip can compress if installed side ways. This leads to clip jumping out and gouging cylinder, head, piston, and possibly destroying crank. Thought you might want to know! Loved the video, keep it up!!
The Dowel hole you ask about at the end is a stop pin you use to tighten the bolt in the power valve. it's a removable piece that gets lost. It came in the original owners kit.
i was wincing just a little. Almost gave me a coronary till I heard torque wrench. lol I'm NOT dssn! i'm just sharing the 45yrs of what shared to me. the key is to ALWAYS! remain teachable like a sponge. Im still learning stuff and "tricks" from young whipper snappers. The 70's was the golden age of mx. The dacade did more for mx than all others combined. Decade of the "big four" 2x invasion is when everything changed. A decade when a some what mech inclined 7th grader could re-ring 77'cr125 in 5min.....on the grass. no sh't a decade when you rebuild the top end between motos. 2x tech each yr grew by 100th power. giving birth to hi-performance after market industry. Those were the days. i said all that to say this; REMAIN TEACHABLE! Im still learning; even from young whipper snappers.. this is what helped me make easier-faster. When motor is still in the frame i loosen & or remove as much hardware as possible; I use a breaker bar. Use anything to add length on wrench pay attention. Some idiot may have a brother who knows somebody who stripped it. After loosen cylinder bolts; use steel mallet and cloth lightly criss cross tap the cylinder till it breaks the seal. Then i remove the motor. i made my own universal motor mount bench. it spins motor 360° It's portable and i can clamp it to any bench. easy peezy. Love yer vids bra
that set of holes under the power valve is for a dowel or pin to lock up the linkage so you can tighten the nut without damaging the linkage or ruining the powervalve governor under the clutch cover. Nothing missing
Hi great video and great series, one tip I would like to give, that I wish I had of been told long ago, is to never use the palm of your hand to hit anything, It is a number 1 cause for carpal tunnel, I had a lot of issues with my Thumbs being unbearably sore, I later found out it was from my general operations at work, that were not pointed out to me that were dangerous for long term (hand) health, since then I have never hit anything with my hands/palm/wrist at all and now have full movement of both my wrists and thumbs without pain.
Hey man awesome videos I am so stoked to see the finished product I am doing a build myself on the YZ125 and it's the 2001 year I'm not going as intense and in detail as you because I don't know as much but if it's not too much trouble you should show how you put everything together if possible I know that might be a lot of work but it could be really informative to a lot of us that don't want to waste a lot of money taking it to a shop for something that could be a simple process it's just I don't know how to actually do it step-by-step and correctly but keep up the good videos man these are probably the most fun and informative to watch that I've seen on all of RUclips
u do great work.... what u should also do to double check ur work is to go to the web site of the brand of bike that ur working on, & they should have all the blue prints to the bikes lay out to see what peace fits were and how it goes on ect. thats just a sugjestion for future refrance
I use a site called Bike Bandit and they sell OEM parts. But is shows diagrams and parts numbers so you can probably find that little rod you were looking for.
That gap on the valve linkage at the end of the video is just meant to be there to disassemble the valve. You're supposed to put a pin inside the hole to hold the linkage in position when you unscrew the bolt, on my 06 it was pretty tight and i had to use it. Did you clean the whole valve system finally? make sure to tighten the bolts and screws enough, otherwise they will tend to get loose after a few hours, i had to put some threadlock on mine.
Okay sweet! Thank you so much. And yeah i got everything really tight. i will need to see how it does after a while and if not then i will add some thread locker
Yea threadlock is a must, my 05 screw went lose making a mess out of my power valve and breaking it, cost me 250 bucks for something that could have been easily prevented.
dud i am knolage about bikes but i do work on alot of car engines and one thing you can do to get the oil off your motor is that you can use engine clearner and just leave the parts you want to clean in there overe night and it does a great job
I don't think ur missing anything where your power valve is hooked up because on my bike it's a groove that you put something in it so that when you tighten the bolt it doesn't damage the power valve.
Great video, but quick tip, NEVER use a metal hammer to loose the jug.. use a rubber mallet.. hell even using a piece of cut 2×4 would be better, but use a mallet, $5 at harbor freight and will save you a lot of grief.. u almost have to be tryna damage the cylinder yo ro damage with a mallet. Not tryna be a jerk, just letting you know for future builds 💪🏾
To be honest I really love my 70° Husabergs but very time I see a video from a tow stroke top end rebuild I understand why some people love two strokes...
I don't know if you did it or not but when you put the cylinder over the piston you want to put some premix oil over the piston coat it with premix oil.
Good video just one thing I picked up when you where taking of the cylinder use a plastic or rubber mallet to lower the risk of cracking the cylinder I've cracked mine oops
As much as I enjoy these videos, they give me anxiety lol. You really need to clean parts better before fitting new parts. You also definitely need to invest in proper tools, namely a torque wrench to start. I get it, you're not an expert (neither am I) but my OCD is blowing up over here watching this video haha. After all that, you're videos are entertaining, and aside from the anxiety part, I really enjoy them ;)
@@garyleopard8823 never wash a dirtbike with a pressure wash, you're supposed to regresse every bearing on a bike after short period of time, something like 10h, if water gets in there, it will rust and malfunction
hey buddy loved the video just wanted to know what year was the motor you were working on the video as i have purchased a Yz250 and have no VIN number on the bike it has been grinded off by the previous owner.. could you please tell me the year as my engine has the same series as yours but i am unable to trace the actual year of my motor..thanks
Nice vid, I have a question, where did you buy your piston and your crankcase for the clutch and the ignition ? (sorry for my bad english, i'm french) Great point of view, nice quality, nice camera, continue like that, it's perfect !!
Good video mechanical skills are a little rough with regards to removing the cylinder head and the drive sprocket, to make life easier remove the sprocket nut while the engine is in the frame and chain still on.. other than that great video. Enjoy the end product 😊
Must be nice having a the right size ratchet for every bolt
Great video. Very entertaining. Great camera angles. Can i just suggest one thing. Get a dead blow hammer or a rubber mallet for removing your cylinder rather than a steel hammer.

People remember don’t hit your engine with a hammer use a rubber mallet if you use a hammer it’s going to be more work and more money
the boy next door I almost cried when he did that
l like this one
Use a rubber mallet..
Or a block of wood pound at it
You can warp or break a cylinder
no he didn't, he said so but he did first the rear ones and then the front
this whole series is something like "answer to: wtf the previous owner did to your bike"
300$ on covers and graps.. but hey better cheap out on torque wrenches, socket sets and tools
Or use your man hands
that hole in the powervalve is for putting a pin to stop the valve actuator from moving when tightening the bolt to spec
Looking Good! I have done a rebuild on my 96 yz250, but the thing that set mine apart was that I changed all bolts! I recommend that you should do it aswell!

Blaster528 No.
Completely agree
Hey, goatman. Why don't you elaborate on why you disagree...
I bought a kx 125 the next day I rode it for about 10 min and the clip snapped saddest day of my life I have no clue as what to do with the bike
was looking in the comments for it to be said
The Dowel hole you ask about at the end is a stop pin you use to tighten the bolt in the power valve. it's a removable piece that gets lost. It came in the original owners kit.
9:55 it's just a place to put a pin or whatever you want if you want to stop the power valve from working. I've got a similar thing on my dt125

It’s nice to see someone who knows how to work on engines do stuff like this. Usually people in video do it wrong
The hole in the power valve is so you can stick a pick in it to hold the arm it’s for breaking loose a stubborn power valve link.
Hi great video and great series, one tip I would like to give, that I wish I had of been told long ago, is to never use the palm of your hand to hit anything, It is a number 1 cause for carpal tunnel, I had a lot of issues with my Thumbs being unbearably sore, I later found out it was from my general operations at work, that were not pointed out to me that were dangerous for long term (hand) health, since then I have never hit anything with my hands/palm/wrist at all and now have full movement of both my wrists and thumbs without pain.
When he hit the first bolt it sounded like the beat at the start of Shotta Flow 1
The little hole ob the linkage is an indicator it show where the valve needs to be when its opened at least on my bike
That place where you thought there was a dowel in the power valve area is a hole to use an Allen to hold that linkage still to remove the bolt easier
The intro alone worth the thumb up!!
really good video, i can see you're genuinely putting in a lot of effort with editing and positioning cameras, i'll be waiting on the next video!
Hey man awesome videos I am so stoked to see the finished product I am doing a build myself on the YZ125 and it's the 2001 year I'm not going as intense and in detail as you because I don't know as much but if it's not too much trouble you should show how you put everything together if possible I know that might be a lot of work but it could be really informative to a lot of us that don't want to waste a lot of money taking it to a shop for something that could be a simple process it's just I don't know how to actually do it step-by-step and correctly but keep up the good videos man these are probably the most fun and informative to watch that I've seen on all of RUclips

The hole is for a dowel just for installation it’s so the power valve doesn’t move wail torquing the bolt down then you remove it
I only watched this series and just started this video, I subbed because the memes are steamy dank
Where u say the dowel goes.. its where you stick something in that holds the area where the bolt for the power valve goes.
I watched you move the rod up and down hahahaha bottom end if clapped
I use a site called Bike Bandit and they sell OEM parts. But is shows diagrams and parts numbers so you can probably find that little rod you were looking for.
The little notch in the powervalvesystem is just for adjusting the valve.
Nice build! Waiting for pt4!

I was flinching with every hit of that lump hammer
Dope video man, can't wait till you finish your project!
dud i am knolage about bikes but i do work on alot of car engines and one thing you can do to get the oil off your motor is that you can use engine clearner and just leave the parts you want to clean in there overe night and it does a great job
The Engine looks like a different engine it's so clean 👌👌🏅
I was honestly waiting for the hammer action to crack that cast aluminum. Plastic dead blow buddy. Great video though. Kept me entertained.
Battery powered impact is your best friend for disassembly. Be careful assembling with an impact though :p easy to over tighten and break easily
I loved the video so far and I really want you to keep on going on RUclips
I don't think ur missing anything where your power valve is hooked up because on my bike it's a groove that you put something in it so that when you tighten the bolt it doesn't damage the power valve.
lifter arm? haha i had to poke fun. connecting rod.
You should get the boyesen supercooler to match the covers.
Great vid man, loving the Skyrim shout out. lol
You got me subscribed when the Skyrim theme came 😂
you should replace all the bolts and nuts, so that the appearance of the engine looks cleaner and looks new
I like the fact that your not a professional with 20k tools in his shop and a 30k crew filming, great content
You need a rubber mallet and a impact electric or air would help you out a lot I think
Very good video ,entertaining and helpful good job
The rod has down to up movement GL seizing up.
I thought I was trippin. I saw that too
Great video, but quick tip, NEVER use a metal hammer to loose the jug.. use a rubber mallet.. hell even using a piece of cut 2×4 would be better, but use a mallet, $5 at harbor freight and will save you a lot of grief.. u almost have to be tryna damage the cylinder yo ro damage with a mallet. Not tryna be a jerk, just letting you know for future builds 💪🏾
Keep up the good work. You should do a series on a Yamaha Banshee 👌🏻
Hey, how did you shine up the cylinder? The metal looks amazing !!
How do you keep track of screws nuts and bolts and know where to put them back
You are missing the screw for the power valve assembly. Good luck
To be honest I really love my 70° Husabergs but very time I see a video from a tow stroke top end rebuild I understand why some people love two strokes...
Man your videos are so fire keep it up your channel will blow
I don't know if you did it or not but when you put the cylinder over the piston you want to put some premix oil over the piston coat it with premix oil.
you deserve more subs because these are gold
Make sure to change the spark plug
Air hammer works good on getting the cly off lol
What did you use when you cleaned the outside of your motor, did you just sandblast the whole thing?
Yes metal pin fell out was in on the strip down on power valve
It’s a crime that you don’t have more subs
i think it'd be a good idea to clean all the gunk from the engine before reassembling it
So you spent almost 200 on black boyesen side coveres that wont do anything but look good. Why didnt you powdercoat the old ones?
Can’t wait for part 4 😀
The bikes engine looks amazing 👍
Lifter arm? You mean a wiseco connecting rod?
Great video man you did so well
Thank you for the video , what year model bike is this ?
Keep up the good work man grate series
I just wanted to say... you have to measure the thickness of the base gasket so you can get the correct deck height / x dimensions
96 YZ250.. what a beast
Good video just one thing I picked up when you where taking of the cylinder use a plastic or rubber mallet to lower the risk of cracking the cylinder I've cracked mine oops
Hell yes dude, loving your videos. When is part 4 coming?
Makes it seem soooo simple
use a torque wrench on the cylinder and head nuts
lol rookie move hitting that jug with a hammer.
xhxr6tmods how would you get the cylinder off besides a hammer or dead blow, considering it's stuck
rubber mallet
a rubber mallet 100%
Rubber mallet. Or if it's not covered in RTV silicone like his sometimes you can just slightly wiggle it loose
xhxr6tmods this guy is right. Use the rubber mallet not the dam hammer on especially a cylinder!
Hry men... Where did you buy the black mitor caps? Thanks
This guy should have more subs😮
Good vid, i hate when people put gasket maker on everything!
Might be wrong but it looked like quite a bit of play on that big end bearing.
Yes your'e wrong.
mike James ok. Thanks.

Colin Trevor he used a torque wrench... just didn't say show it in the video
Pressure washing bearings and seals is never a good idea either
@@IanCoomer why not ?? Can it cause problems like.
@@garyleopard8823 never wash a dirtbike with a pressure wash, you're supposed to regresse every bearing on a bike after short period of time, something like 10h, if water gets in there, it will rust and malfunction
This is interesting... and also very helpfull thx
Next time , put the piston on the cylinder first, then put on the cylinder to the engine . Its much more easier that way
Where did you learn how to do all of this work
Did you paint the aluminum or just clean it up ?
Brutal makeover
Whatch you video you dropped the dowel wen you took of the cover....
Love this series
hey buddy loved the video just wanted to know what year was the motor you were working on the video as i have purchased a Yz250 and have no VIN number on the bike it has been grinded off by the previous owner.. could you please tell me the year as my engine has the same series as yours but i am unable to trace the actual year of my motor..thanks
Bro, you can tell by the powervalve
only 19k subs? u deserve more!
why did you not use a breaker bar?
U didnt oil in the Piston and cylinder?
Dude are you a 9gager?
Great video👌 with those boyesen covers the engine looks so professional🔥
