I just picked up a 1990 moto4 Champ 100cc (a step dwn from the breeze) It needed alot of attention. Broken snap rings on the transmission, clogged oil strainer & as if that wouldn't stop it dead, a peace of the threads where the spark plug screws in broke & fell into the combustion chamber. Cleaned it all up without replacing a thing except the snap rings & whadda you know- It works!!! Don't know for how long but it works.. My first ever complete engine tear down..🤪🤔. Couldn't have did it without you Mann.. keep em comin....

Tip from Ike at Cars and Cameras. If I Philips head strips out, take a saw, and cut a deep groove in the middle of the head so it turns into a flat head

You over revved you engine and floated the intake valve because it’s bigger it’s easier to float and bang it bent

9:16 that's what she said

it jumped timing by at least one or more teeth, you need a new timing chain and i would replace the entire head with a good used one and just relap the valves in the new head because honestly its cheaper, also check the chain guides because if they'er grooved it will allow the chain the remain loose even with the tentioner. the base gasket is blown beacuse when it jumped timing it pressurized the crankcase, so you will need a new one of those as well. i should add that im a 30yr seasoned tech. hope this helps bud.

I’m having a lot of the same problems. Your explanation didn’t go unnoticed thank you so much. Hardly anyone knows anything about this old ass super simple quad

do valve seals also cause the bent valve couldve stretched it and im sure it could use them. also be easy taking those rocker arms out after you set up the puller cause you can very easily damage the case or even press them in too far and they can get in the way of those long head/cylinder bolts when you try to put it back together

Migs you a fool man 🤣🤣🤣 @ 1:08 keep doin what you doin bro 💯

U can always get stripped Phillips or any other bolts by using a flat head or chisel and hit the head make a groove and then hit it on an angle to loosen it works most of the time the shock helps alot i also heat the bolts if they wont come out without stripping and impact screwdrivers help alot also

Those are JIS screws(japan industrial standard) they are not philips screws you need the right tool !

Just picked up the same Yamaha breeze, and for some reason the bolts to the air box lid are missing. Any idea What the bolt dimensions are? Can’t seem to find replacements online

Lets go miggs.

It was your intake valve that's bent not the exhaust

Lol. I did the EXACT same thing with the timing chain took off all the bolts and was wondering why it was still stuck. Felt rly dumb after but that’s how u learn

Migg's man not to b e mean because I've done it myself sometimes but watching your knuckles hit the bench Tickled like crazy...

Hey Migs you should do a full rebuild on your klx 125 😁

When u don’t have a compression tester put your thumb over the spark plug hole and turn it over and if your thumb gets blown out of it then u have good compression if it doesn’t then u might need new gasket or retighten your rockers

That breeze seems to be running good in your previous videos. When you pinned it did did have some sort of review limiter to prevent over revving or do breezes don't have review limiters installed on them?

Migs I know you said a few videos ago you were getting bigger bikes well if you want to get a quality bike for $2000 get a ssr 150 or get a used 250 but keep up the videos😎

I was watching you try to wiggle the head off and just thinking mate its a over head cam engine, mabey get rid of the timing chain but you got it sorted

Make sure u put new gaskets on when your putting it back together

Hi love you man

You may be able to find another good head on eBay for about the same cost as new valves. In my experience when a valve bends it's possible the valve seat could be damaged as well as the valve gid, so I would suggest finding a good head.

I have the same type if quad when i try to start it there is a loud rattle noise and doesn't start i think it might be the timing chain but im not sure please help

My xr 200 smoked like a paper mill but still had all the power just did a full top end rebuild

Go to 10:12 and put on 0.25 speed

@motomigs if you think it is blown up and you oil cap doesnt have a magnet on the plug the take a magnet and run it across the bottom of the pan and bring it to the hole and if you get shavings then its blown

Just order a piston kit anyway at it probably needs a gasket if theres oil leaking at the bottom of the cylinder

What explains the rattle mine does the same thing

Change the oil and get a compression tester and fix the exhaust your running it really lean.

Omg it’s so dirty!

You should take apart the bottom end and check it just in case, something in there could have broke and made the exhaust thing bend

I have the same four wheeler and it might be the fuze

He should break stuff more often

Since its a yamaha those are JIS screws, an american philips head will just eat the JIS screws. You can buy a JIS screwdriver set on ebay and amazon for like 25 bucks

Hello,I'm trying to pull off my timing chain sprocket. It keeps spinning. How do I keep it from spinning?

I’m assuming you have to remove the lower engine cover that you can also crank the motor with and hold it while you torque the other one. Did you happen to figure this out? I’m debating spending the $13 for the service manual.

I believe those are air cooled it's not smart to just let them run at idle without moving. They can over heat

well oil is leaking from where cylinder meets bottom end, that would mean bad gasket, which could be why it was idling and running weird, an air leak

Thanks, I was trying to think of what that tool was called this morning. Totally unrelated, just a nice coincidence lol

It's an air cooled engine if you run it and not ride will cause the engine to over heat and your exhaust valve looked pretty warped could have been previous owner just to be safe get a whole new head and valves your overhead cam and sprocket should be fine to reuse

Am I the only one that would have checked the valves prior to removing the head?

Old fashioned compression test.... Put your thumb flat against the hole and turn the engine over a time or two.. it should blow your thumb or finger away from the hole.. if not.. no compression

Not exactly as the title implies..BLOWN UP!? That was a small clunk and rolling stop at best!

The exhaust thought

with the spark plug put sandpaper strip and rub it everywhere and try it again

In Vietnam heloo

the bigger valve is the intake

Just jb weld it lol

Bending a valve and blowing up a bike aren’t the same a blow up is the piston ands jug assembly lmao

mega ripp

My moneys on the timming chain

I'm having the exact same problem but I can't find anybody with a video showing how to put the timing chain in cuz mine's broke yours is broke I'm sure

Gaskets. That’s what went

Cool 🚲💨💨💨

That will be a breaze to fix

that bike cant over rev because yamaha has a limiter built right in to cdi box, people need to know what they are talking about before they just start shooting off at the keyboard, valve float only occurs when you have either a weak valve spring or have somehow modified the bike to bypass the limiter, which i highly doubt has been done to that bike, and this is yamaha not china junk.

My mower runs rich all the time n hasnt blown up yet and i have it idle higher than stock idle because i got thick grass

So he reved it to high and floated the valves so they touched and bent

Why did he call the cam gear a cam 😂😂😂

ur intake valve is bent not your exhaust, remember that exhause valves are always smaller. just for the future

Oh dear😔

But WHY.. Did the valve bend, Check the teeth on the stator side of the motor the one that drives the cam you could have stripped something there that's probably why you bent a valve

Man I blew up my Grizzly 700 twice! damnit.

why rev it did u not see this coming??? hep if my wheeler is doing that just fucking rev it tell she blows man lol might fix it also did u make that shed or buy it?? just wondering

I can't believe you bent a exhaust valve doing that. I'm guessing you route to your motor a little bit too much next time don't do that kid and one more thing if you keep busting your knuckles on the bench like that you will have crazy man hands in no time.

Apparently you've never done this before neither have I not on this model anyway and I'm thinking you're going to find it your timing chain is broken because it's on there mine was on there but it was broken but it was still on there but it had zero compression

Who noticed 5:04

You need to get an exhaust

It’d be cool if you swapped in like a yz85 engine or some sort of 2 stroke engine to make this thing haul! Also sub to my channel!

Buy a yamaha blaster

How can’t you tell which is the intake and which is the exhaust? It’s very obvious if you have any clue what your doing.

The exhaust valve is bent not the intake

Did you seriously call that gear the cam?
