“I don’t know man shits looking like chocolate “ mike cracks me up every video
Literally bringing the engine back from the dead while spending the least amount of money you can. You are probably the coolest mx/atv youtuber out there right now.
I love the 125's I own a 83 with a full engine rebuild I paid 1200 for I'm doing a frame off restoration this winter to bring the rest of the back to original

Nice, I have a 81 YZ 465 that's currently a basket-case project. Sadly it's one of those things I keep talking about and haven't started yet. I have too many things that all need fixing at once. The YZ is going to take some time, I want to do it right and it's going to be painted a similar color choice as Mike's 125. But I'm wanting to do it in more of a late 80's early 90's theme. Almost like a KX 500. :)
I always get happy about stickers also cerakote the very top of the dome give that new piston a long life
Did a yz125 big bore kit a few months ago and I had too port the bottom cases to clear the piston skirt it would hit at the lowest stroke and the power valve would get stuck ,so definitely Polish that rough finish
Raptor 250 with that motor! Ultimate pit quad!
Glad to see you working on the yz125 again 😃👍
I'm excited to see this underway!
Killer, I imagine the fun factor will be off the charts when your all done.
Right on Mike. I'm glad your finishing up on the YZ..Congrats on 70k
That engine case looks mint! :)
Hell yea brother!! She’s gonna be sweet looking 👍🏼👍🏼
Nice vid Mike. I'm not a bike guy but I loved my pos 96 yz125. Pretty excited for this build. Keep it up. 🤘
You video is my Bible for my Zilla build
If you don’t like that color combo on the clutch covers, I would strip it and go burnt bronze Cerakote and whatever the gray is. The colors Niemela uses.
It's going to look great. I like the dark "chocolate" color. The gold I would have gone a bit brighter. I'm thinking like Honda gold, but metallic. Doesn't really matter, it's going to look badass.
Awesome work man! I can still remember how excited I was when I first unboxed my 434cc Athena kit for my Suzuki ltz400! They make great products! Great choice!👌
Not a super dirtbike guy anymore but I had an 01 yz back in the day. Just glad to have another sabo engine build on thr chopping block haha.

Thank you as always bro!
144s are awesome! Excited to see how this one comes together!
Hot Rods is 50/50. Sometimes they're great and other times the rod snaps at the piston and takes out the entire engine. Had one that lasted hundreds of hours on a big bore trx450r and still running. And another that lasted 20 hours. Always weld the crank
Wrench rabbit is who does it all in one with transmission bearings i always go with them soon ill have my channel bumping maybe one day we'll get to do a build together
Looks good I like the colors reminds me of a Reese Penutbutter cup looks good
🤩🤩 like to see new parts like that
Hell yeah this is what I’ve been waiting for. Would be cool to see you build an air cooled two stroke.
These build videos you do Mike are the shit, keep doing them!! 🤙🤙🤙
Clean work bro!!!!
Of you got the space get a vapor blaster the sheen of three case will be more uniform with each other.
Looking forward to this build 🤙🏽
Colors look sick bikes going to be a sick azz bike !! I can't wait to see you build Jon's zilla
Motor looks great 👍
Nice work man real attention to detail love the content!
bout to be a beast🔥🔥
Love your vids man !!!
Finally I've been awaiting this
I love build series . Keep it up and were gonna be at 100k subs soon
I hope you make a compilation video of the crazy voices you use to express the comments of all the complainers and whiners. It would be very funny.
FYI Athena and Wossner are actually made in the same factory in Germany, at least that's how it is for Europe.
Awesome vid and edits and filming and motor
gonna be cleannnnn
Athena has always done that rough finish at least my experience i always smooth em
You deserve more subs
My 144 kit Had a A piston not B. strange but bad ass build man.
Oooooo I see the Polaris outlaw owners manual - did I miss that one!?! Very interested in the outlaw 525 and considered buying one, ended up going with a yfz450 after seeing the parts availability for a outlaw…
Think I need you to clean my cases lol
paint looks mint man i like it not chocolate if u ask me haha
I have a 1983 CR250 if you're interested DG pipe custom billet silencer bike is immaculate
Just finished rebuilding my buddys rm 80 for him
Dude for as long as I have been riding and wrenching on bikes quads I have never seen a cylinder look like that. I would call then about that most definitely. Looks like the took it out of the mold and packed it on the spot. Never seen that shit before. Well I know where I'm not but a cylinder. Lol
I think you should smooth the cylinder out and coat it.
try purple powers aluminum brite. works way better then napa
It would be cool to send the cylinder to extrude hone
Don't worry about the purple head the tank on YZ's will cover it. Noone will see it lol
Dilute Muratic acid to about 1/2 a cup and the rest water. Makes aluminum look brand new. Saves a lot of time!!!!!
Noti gang big W
Hey man! I’ve been wondering if you know how to lower/ (maybe?) bag a four wheeler. I want to make a drifter but I also want to lower it a bit,
With all these mad colors , maybe turn into a super moto . Stupid fast John and u can race at the go kart track. ......
Oh and hey I just dropped 1900 on a yfz450 stroker kit from BP and tried to use your code over the phone. He said he would. But then didn't. And gave me some number of "oh the price is actually going up on that kit so we charged u what it shows online" says I still "technically got the %10" but I wanted to lyk b.c. If its supposed to help u out or your sponsorship then thats kinda b.s. 1900 a big purchase u brought them lol and now the pistons on back border i guess. I tried for u bro, love all your builds man!!!

I just saw your older comment mentioning this; sorry about the code mishap man but I really appreciate you wanting to support regardless; hopefully by now that kit is installed and it was at least worth it 🤘
I got the same year same top end bike it screams.
👍👍👍
Mike, Hello, How did you get the clutch shaft out of the clutch cover? Please Help!!!!
Yaaaas
Is their anyway yous still have the cylinder head I've been looking everywhere for one just can't find one, for my 1998 yz125 would love to buy it off you.
Wiseco and hot rods are the same company now, and they have not alleviated the issues, rods on both of those cranks need pulled apart, checked for tolerances and then re trued, dealing with several of their cranks that have locked up with less than 5 hours

Definitely don't recommend them in a modded engine. I have tons of bad ones here and their crank bearings are even worse. I have video where I talk about oem, hotrods, weisco cranks and show the difference
If you weld that crank you’re gonna have a helluva time truing it because it’s guaranteed to get tweaked, I don’t think a YZ125 makes enough power for it to matter.
Take your scotch bright wheel to the cylinder
How far can you file those fingers down on the clutch basket
Bro hb we change her name to the "grapefruit ape" 👊
Looks like chocolate and peanut butter
happy to see this , colour scheme is 🤮 but hey i’m old prefer the white /red yzs. it’s your bike though so don’t take it personally
Mike can you & john do Bike Warz..

Bro they can't even ride quads and bikes take more skill.
Better off getting rid of that drill battery, if it’s swelling, it’ll blow and they set on fire, you’ll burn your garage down 🥴
Those power valves will only work in the Big Bore cylinder it's the same if you have a cylinder overboard and replated you have to have the power valves cut to match the cylinders are garbage Athena makes garbage they make good gaskets that's about it
Not to sure about that head. I wouldn't let a part leave my shop that raw and shitty looking. Cool change gonna be cool little bike👍
Idk about welding the crank you might throw it outta balance…… I wouldnt feel comfortable doing that. Jmo
Mike please do it red and white , or yellow and black , like vintage yamahas , oh that green man 🤮🤮
👏🏽👏🏽👏🏽💯🤣👍🏽🙏🏽🙏🏽
Last
Polish the cylinder bro
Second
Those Athena kits are garbage their cast Pistons do yourself a favor throw that in the garbage and buy a wiseco piston make sure you chamfer the ports really good as it wasn't done good out of the box
That kit ends up being a 154
That kit is actually worse condition than the one I got the one I got wasn't so coarse and porous like that
First
chemicals will make rubber swell like that. like brake cleaner and stuff
Hotrods crank bearings are Chinese junk. Cranks not far behind but better than weisco. I would recommend not useing the crank bearings and get koyo or ntn for it, 40$ on eBay. Goodluck 🔧🔧
I stopped watching when you started making videos with that disgusting pos trucker I never liked that guy. I like your new content I’m glad I checked back in.
