Seller Said This 250cc Dirt Bike Shut Off While Riding So I Got It CHEAP 

Me to🇦🇺👍

My thoughts as well.. straight gas ⛽️ then boom… then the realization, “forgot the oil” so before returning blown up, oil was added as well as the “I don’t know what happened”

That's what I thought too.

Time to call LA Sleeve 😬

The fuel didn't look mixed when he tested the petcock.

Ditto, straight gas been run for a period .

each of those fancy green lines added 10 HP

Dont they lol... I thought the same thing. Brought back the 70s for me mate lol

Yes, those definitely need to be replaced with coolant resistant hoses.

They are legit Kawasaki Green lines.

Less oil = More fuel = Rich / less oil would create a lubrication problem, not a lean condition; I think Joe is right on, was running way too high air to fuel (lean) created a lot of heat and grenaded the piston. My guess is an air leak down stream from the carb.

@@user-mx6ce6vv9f Nope, it's lack of oil in the mix. Yea she was running a bit lean(plug) but not enough to cause that damage. It's pure friction damage. AND he said the locked up in mid jump, amateur rider with no throttle control over reved it. typical ricky racer over reving and constant throttle blipping

@@mazdarx7887 Your both wrong he checked the fuel it was colored so it had oil. both jets, air screw, and needle were rich especially the needle so an air leak is a bit unlikely the cause.

@@PurpleMonkeyWaffle It had oil, but how much. By looking at a fuel mix tell me how you can tell the difference between 30/1, 40/1, or 50/1. If you had the fuel and oil that was used, mixed them at varying mixtures, you may see the difference. Barring an evaporative or IR test you don't know what was in it when the piston failed. But the key is in the needle bearings. They take a while to wear out like that, not just a minute or so of overheating. We used to race 2 smokers in the 70's and seen many types of failures, The head shows lean and not enough oil. Pistons grenade like that from overreving, too small for the bore and lack of oil. Now on the other hand, there may have been enough oil in the fuel by not mixed to a homogeneous state(most people put the fuel and oil in a tank and shake it for a few seconds. We always put 1/4 fuel in tank, added required oil for the mix, shook for about a minute, the added another 1/4 fuel shook repeated till all fuel was in. The oil will separate if not mixed very well. It will look like a lean burn on piston, and plug, but the bearings tell a different story. Then the over reving, now-a-days you don't see it so much with rev limiters. Watch a good rider jump vs a ricky racer. Ricky racers usually wind em out in a jump can even hear the limiter kick in , but not good or pro riders

@@mazdarx7887 I would lean more towards the fuel mixture being the issue. That bike was meant to be revved in the higher RPM's compared to the bikes of the 70's. Your 100% right that there is no way of knowing what the fuel mixture is. These days, alot of the 2-stroke oils being sold (atleast quality oil) is the same color as the fuel so it is very possible this was just some person that had no idea that oil needed to be mixed with the fuel and they just threw straight pump gas in the bike.

Have you ever run Maxima oils? cant tell its mixed lol

because the cylinder was roached? or because you figured he would?

I was about to type the same thing.. Good call mate.

Not needed if you are just flipping it for profit.

@@Poppinwheeeeellllllieeeeezso your a scumbag

It is needed if you don’t want to get a reputation for flipping shit. Common sense

You'd think these jobs would be hard enough without taking off everything everyone already knows isn't the problem.

Wonderful isnt it? Kids got some skills, thats for sure. Has helped me a Lo9t already, been watching him since he had like 20k subs. I always learn Something from is videos, worst case its same thing but Drills the problem solving steps in for good and others a Whole new can o worms :) Cheers.

Yes you dont save 15 dollar on that bearing if you change piston.

Hahaha

Where'd you get it bud😮😅😊 0:26 ​@@2vintage

I wonder

That !?! or it was running without coolant lol. Who knows 🤔💯

@@just4kicks950 no I seen the coolant be drain there was coolant in it

@@MusicSensations1971 I seen Joe draining the clean coolant in the vid. Doesn't mean there was coolant when it blew. Maybe the person who did the build forgot. Seen a few come threw Honda service that lost coolant or someone working on forgot to add coolant, to do that kind of damage from heat ♨️ . Just a theory anything can happen, it's 2strokes life lol

Lmao he sells a lot of the bikes on the channel and buys more to further the content. You really think he’s just fixing these and keeping them? 😂 he has a couple of older videos of what he’s actually kept. Mostly rare or vintage stuff

"Looks Perfect !!" I'd buy some of his merch, as well. Hoodies.

Lol...

Hopefully he listen to you but doubtful he will.

Comon man this is joe dirt channel no way he gonna fix it right

He wont listen lol

He's in Wisconsin where millennium tech is.. he knows 🙄.

@@thyreaper650 let him spend 600 instead of 300

Yes I always warm my yz125 2003 an run 25.1 gas mix

Pretty close my area they still bring 2200-2500

@@TroySmith-cz5jy oh, well. I guess we don't count 🤷 the money from half a million RU-vid subscribers watching his channel because he does the tough repairs. Sounds like yall have it all figured out.

They're $2500 in good condition. This bikes had a rough life. It'd be $2k running where i live.

@@JoeTheBlacksmith13 Yes, I had a good experience with using one but I replaced both the Jets and the needle.

A vapor hone would be nice too

Ultrasonic bath cleaner is perfect for carbs....

@@harrybosch5720 He has one.

A Handy motorcycle-atv lift table. Get off the floor

​@@harrybosch5720 He has one

More oil means less gas through the jet that makes a lean mixture

The previous Joe rebuilt it! 😂

Did the same with a vespa was ringing its neck for ages hope u get it sorted 👍
