You gotta respect Mike's honesty. About saying how that piston saw some heat and about the crank main bearings were still in when he shaved the cases. Doing shit the way normal people can relate to.
@@MichaelSabo I wish I could bro, I work @ Boeing as a machinist and I used my last week of vacation time for Dune fest this year, i get my next 80hrs October 26th..
Another awesome video! You can learn TIG.....I was raised on MIG/Stick, but learned TIG to compliment my machining hobby (& I love it!). It takes practice, but there's so much more control. Porosity is hard to avoid on oil soaked aluminum castings....but can be removed with burr bits & refilled. Excellent repair!
Anyone that knows anything about welding will not talk smack about that job. It is virtually impossible to get a perfect weld on cast that has been used in a oily environment.
You always do good work!!! You pay attention to small details and take your time on builds which alot of people don't. Thats why your stuff works. You and stupid fast make a good team!! Good luck on the rest of the build.
I think you did a really good job man and as far as reusing the piston, how is that any different than reringing after the compression drops 10%. Ive done the exact same thing reusing parts on motors and never had an issue. Great video Michael Im looking forward to seeing this beast come to life! 👍🏼
@@MichaelSabo Yeah those kind of people have money coming outta their ass. If you looked there were hardly any scuffs on that piston so that tells me it wasnt in there very long. If you wanted to be picky after seeing that you could have used a micrometer and bore gauge
John did a fine job welding up the cases. Same thing happened to my polaris sport 400 before. the piston shattered and jammed down in the crank cases and i still rode it for a long time like that after it broke free at one point from gently tugging on the pull starter I knew it wasnt good when it.jammed the pull starter from moving. didnt move at all. i didnt know what happened at the time. But after it broke free it had zero low or midrange power.only top.end.but it was the weirdest thing.it being a cvt tranny was the only reason i could still ride it im sure. it was not even able to drive over a little stick If it was in front of my tire from a stand still.i had to get a good running start on flat ground so it would get into powerband since that was the only way it would have power still to even move really.you could feel it slowly building up its powerband.like i said it was the weirdest thing. Top end wasnt any different really. They are actually very powerful engines that have to move a heavy machine.And its not a stock sport 400.its slightly modified
those cases are rough , i hope it works out , for the price of crank bearings i think id be putting new ones in just to be safe. had a crank case repaired a while back and the engine vibration alone opened it up pretty quickly but it was a big crack.
@@MichaelSabo No problem! Yea seriously. Love my Milwaukee tools. I've been looking for a dremel lately and didn't know what one to get. Clearly going with Milwaukee now lol.
Super cool stuff...love the try effort to repair case cases. I get it it's budget build but new crank bearings since it's apart is a wash in my mind, but it's #stupid fast quad. Play the risk with that. Also look forward to seeing you guys at the 250 legends tour in Oct. You should come down on Monday to ride all the smooth sand like we do. We'll see how how well that thing compares to my billet dmr bhp lynx 380R.
What's up Chris! We might be there all week so I may see you early on. It wont hold a candle to the 380 I'm sure; it's going to be mostly stock and blue printed as best I can make it.
Yes that can be saved, if I lived next door I'd fix that for you for nothing, just for your youtube video 😂 John did a good job. My job is aluminum most days but all I can say is keep up the practice. Great work 👏
Yeah thats all fine bro. Re use the piston...send it. Case repair is on point...send it. That mashed dowel....don't send it lmao 🤣 u always do good work so your judgement says the bearings r fine then I'm trust ya bro. I mean long term peace of mind is always good. But on a budget....use them if they don't have side to wobble. I've had really good luck pulling apart 2 strokes, replace seals and gaskets. And put the used crank and pistons back in. (Banshee) and a quick hone. Run mint. Tolerances in spec. No leaks. Crank runout in spec. Send it!!!
Haha, sometimes you just gotta send it; being able to talk with some old timers in the building/racing game, you wouldn't believe the things they've run (and won with) just because they didn't have the budget or resources at the time.
@@MichaelSabo yeah for real! And that piston and cylinder look fine, their a matched pair so id deff send it. And if it let's go in a couple years, we'll it got used til it broke and used its full life. Instead of throwing away a piston thats fine!!!
Nice work my dude clean build I sure hope it’s reliable those lt250s and lt500s aren’t know for reliability but it will definitely be a beast my buddy owned 2 at the same time and man you talk about fast af lol scary fast but a lot of down time for repairs Suzuki just didn’t have the reliability of the Honda’s or Yamahas of the day definitely excited to se this fire breathing monster ripping 🤙🏻.
About the left/right mismatch around the exhaust valve cavity, the cases were all just like that. The only area that really should be matched is the crankshaft side of that base gasket passage anyway. Matched to the cylinder and base gasket. Also, wasn't John the one talking about main bearings in the top end teardown video?
Personally if it was my motor I would at least put new crank bearings in. You already have it all apart now would be the time to put them in. For the price of new crank bearings seam's kind of crazy not to put them in. But either way I like the video keep up the good work.
I understand what you're saying but that would be wasted money. Those bearings look to have plenty of life left in them and if I had to guess the top end will go just from normal use before it needs bearings
Great job cleaning up those cases, they were pretty rough! Really hope he has you leak down test it and also it would be awesome if he had the funds to dyno tune it to get the most power, and I'd have them tune it just a hair rich, that way it's reliable and it's safer on the longer/harder pulls. It may cost a hair more, but it'll save a lot in the long run, preventing it from blowing up from running lean and having it done up right the first time :)
Yo Michael need help with a banshee that we’re working on. It’s having hard time to start and if it ever start up it’ll only for a little bit. And its also spitting oil with gas smells like. Lmk man i know you said sometimes some techniques that you are using is not recommended but... it might help us figure it out. Thanks in advance
I was looking into flying. Your comments are turned off, Braap Nation.. Let's get together in Rockingham or elsewhere! Not sure where you are in this little state. I'm north central just under NH. Drop me a social media link so we can chat. I'd even turn my Facebook back on to hook up with riders, maybe..
I am wondering could you rebuild a 1992 Suzuki LT 250 Motor I do know the bottom end is locked up I took it apart to look and put it back together That's why I know it's broken
Ur guarenteed to be able to reuse them dowels with a blind hole puller and can find cheap ones for 50 or so and you can use the whole set for many things like transmission bearings pilot bearings pto bearings list goes on and on!
@@MichaelSabo I'm in NC. How's the riding in PA? Going to RI in October. I talked to Jon and Jeremy at Nelson I really wanted a custom clutch cover made with my design on it similar to yours.

love when you mentioned it’s not your budget. first thing i thought was “if it was mike’s budget it would be a full big bore zilla build”. 😂

Hell yeah mike! Another great video! It’s nice to see a zuki in the shop.. we have had 500s in the past and I still have my 250. Keep at it!
Thank you man! I'm excited for the 500!
Killed it again!!! There’s just something that’s so satisfying watching build videos like this…. One day I’ll get to ride with y’all.
Thank you Joey; come out to the Legends tour and Rip with us!

Very true man!
Top quality video Mike!! I see you choose the easiest quad out there to be your first case repair! 😄😄😄😄
Can't wait to see her rippin!
You both did a great job on that case repair I’m impressed 👍
Thank you Robert!
Yeah dude…that surfacing just had to be done honestly. I think it was worth the time. Great video Mike 🙌🏻
Thank you Jon!
If you put each case half in kerosene any aluminum material will float to the top, works great for flushing bearings.
Thank you for this info man!
Man i wish you were my personal friend, i could use a guy like you to diagnose my bikes!!
Absolutely love your channel man, never disappoints!
Man I hope you go into detail when making the bike you're really the only one that can help lots of people built their bike I know I need it 👍🏽
Thank you for saying that man; I will be doing an engine build video in depth!
You always do good work!!! You pay attention to small details and take your time on builds which alot of people don't. Thats why your stuff works. You and stupid fast make a good team!! Good luck on the rest of the build.
Thank you for the kind words Greg!
Awesome work as always mike!! I can’t wait to see the build on this monster!!
Damn that was some really good repairs. At i think it was. Keep up the goid work Mike
Thank you Pedro!
Keep killing it man love the videos!🤘
I think you did a awesome job, you make it look easy but I know this stuff isn't easy at all! Good job looking forward to your next video

There's really no problem re-using a good piston, there are just some people that will nitpick lol

I am very impressed with how those cases turned out.good job man. Alot of guts to repair a case like that hahahah
Thank you Evan 👊
Great video Mike, absolutely stunning transformation on some parts that most people would've just scrapped.
U guys are doing great keep up the amazing work cant wait to see thia thing ripping the dunes!!!!
as always man love the motor builds. keep all the content coming.
Cool stuff man! I’ve got the same tig welder. Welding cast aluminum is extremely difficult. Most people would trash those cases major props dude!
Thank you bro! Hope all is well; I see you posted up some more videos 👊
saw the post on instagram last night was waiting for this one‼️🤟🏻🔥

I agree man
Cases look great Mike. Cant wait to see this one running. Also did not know Milwaukee made a dremel.. so i'm definitely buying that!
They also make a right-angle die-grinder similar to the air powered one he's using in the video, and a soldering iron. :)
Thank you Cody; dude pretty much all of Milwaukee tools are game changers!
@@Slane583 Okay i'm slacking clearly haha. I didn't know about the right angle grinder either. Love to try their soldering iron though.

SaaaaaaBooooooo! Love watching you do engine work.
Keep up the great content.
Make sure the wire brush isn't carbon steel when welding aluminum. BIG difference in popping impurities.
That's a very good point, thank you
You can put jb weld in the air pockets to reinforce it
I actually thought about doing this but the area is thick enough that I think it will be okay
Sabo build’s quality 🤙🏽
Thanks for the link too the porting tool I been wanting one for a wile
No problem man; it's actually a really solid tool

Great modification for the ball joint. I’m going to look at doing that on my raptor!
Another great relatable video!
What do you use for sand paper when you surface the cases and heads? Haven’t found a link in any engine build videos.
Arn't you worried that all that grinding will get in your bearings? EDIT: Ah you mentione it at the end!
About the left/right mismatch around the exhaust valve cavity, the cases were all just like that. The only area that really should be matched is the crankshaft side of that base gasket passage anyway. Matched to the cylinder and base gasket.
Also, wasn't John the one talking about main bearings in the top end teardown video?
I need help choosing some extended a arms and suspension for a 2004 yfm350.
Mike, What are you using for a surface plate to hone case halves?

Nice work man! She’s no 250r but i still love too see the progress on this old dog
Idk what it is but I love working on small engines. I love this stuff.
You need to hit up Dr. Q to get that fixed correctly. He's the master of everything Suzuki LT especially the mighty Zillas.
Talk about 250r legends tour I’d love to go but I’m real far away. Btw keep er up mike 👌🏻
I will be at the legends tour again this year. hope to see you there.
See you there man!
Were should I buy parts for my 86 lt250r
what do you need I have 2 parts bikes.
I have a list of companies I trust in the video description. For used parts, "The R Shop" has a ton of parts; you can find them on ebay.
But very good info and honest videos.the cases turned pretty good for the shape they were in
the YZ is lookin good man
Hey sabo your kinda close to me I have a stock bore banshee and mean yfz thatll be great addition to your quad wars🙏🏼
John bought a cool head but not a new piston… you know those things just explode when they get real old right?
The piston? I don't think it's got many hours on it at all
Good work bro glad he is paying you 700 a hour to counter that welding price lol
Lmao 😂 Thank you Dave
Nice work!
Oh man, going to run that brand new dome with a used piston? 😱 Fingers crossed!
Good job, what’s that black material over your table top
Good work👍🏻👍🏻
Sick vid ;)🇺🇸🇺🇸
Great job 👍
Looks good man
