26:56 He’s got the chain going underneath the lower chain guide, instead of thru it.

Dude is a pro at gassing the s*** out of it when it’s cold 🥶 ⛽️

hey man i got a non running bike and got it running all my self and i am only 17 years old your videos gave me that motivation ❤

This channel is better than tv. Honestly

I’m not a big fan of motorcycles but I love watching you wrench on them, you make great videos I truly enjoy them your a genius with these engines!!

Might need to move that throttle needle one click down. Seem a big groggy in that mid to high range. But more importantly, CHECK THE FLOAT HEIGHT! Im telling you, you will never get a good tune without checking that first thing! Edit: Also By the sounds of it, it either needs a new plug or the coil contacts needs to be cleaned (Misfired between strokes) I posted a video if any of you want to hear what that may sound like on a 2T (Read Discrpition for detailed info on why). Both are super easy to do. This bike has insane potential. What an absolute steal!

Not many people can do that, you amaze me with every video giving inspiration to others keep up the great work we love it

I'm fairly certain the chain needs to be routed through the rear chain guard, not underneath it.

Need to put the chain through the rear chain guide

Definitely some serious out-of-order editing going on. First, clutch goes on with the primary gear missing, and I’m laughing lol, then next clip clutch hat is on, and low and behold the primary gear is on haha.

Great video. But i don't understand why you do all that and not taking the time to clean everything properly.

personally i would have changed the crank seals while it was apart. also, you left some old gasket remnants between the case halves. its a waste of time doing jobs like this if youre not going to do the fundamental things

I like the variety of machines you work on because you aren't afraid to tear into something new and work through it.

I follow a variety of channels, but yours is one of the most anticipated. Enjoy your content. Keep up the good work and thanks for the quick updates.

Chain needs to go through the rear chain guide.

I don't ride dirt bikes but I've always wanted to. I'm a fan of the old 2 strokes. I love the sound, smell, and the smoke. They seem very peppy at high rpm too. Nice work on the rebuild of everything.

Great job on the diagnosis and the rebuild. I loved riding those CR’s back in the day. My last dirt bike was an 89’ CR250, rode the hell out of it until it was stolen in the mid 90’s. Never got it back. Decided to pull the plug on dirt bikes. After seeing and hearing you rip that little 125 around a bit brought back a few memories. Should be a nice bike once you get it dialed in. Great job on the video!

You've given me so much confidence in rebuilding my son's bike.. been dreaming of riding with him for a long time now unfortunately these new bikes and even an old bike that runs are just way too expensive so I have to buy bikes that don't run and try to make them run.. thank you for your videos sir..

Your excellent at what you do ! Wow, incredible work Joe !!!

Something you may consider, I spray down my exhaust pipes with black barbecue grill hi temp paint. Cheap and effective! Great job as always!

I was wondering when you were going to put the main gear on and then poof. It was on without taking the clutch basket back off👍 satisfaction of bringing something back alive is a drug. Stay high my friend 😊

Love these vids and watch them constantly. I have to mention I dont get some of the procedures in this way. When I get a bike to work on the FIRST THING I do every time is drain the gas tank to bone dry and clean the carb(s). Usually I put a filter inline but if this isnt done you are really shooting yourself in the foot since crud in the tank will just keep clogging the carb no matter how many times you clean it. I would not even try to start a bike til I did these simple things. Keep up these vids as they are hugely entertaining and for a wrench like me very relaxing and peaceful to watch. Oh yeah maybel consider wearing a little gear when you ride so my 9yr old son doesnt have to keep telling me "he should be wearing gear" and to keep the next gen of dirtbikers safe.

Good job Joe , i always enjoy your videos , a recommendation would be always take your trailer with you when you are alone on your land so you do not risk hurting yourself unloading any bike out of the back of your beautiful truck. just a thought

So good to watch it helps me learn more about bikes and how to fix them

Nicely done, bike does not look to bad for being a 93'. I like the aftermarket plastics kit on there too.

The chain is under the rear chain guard. Not sure you have noticed.

Love the sound of the 2 stroke. Nice job fixing it up. Love Honda CR s

I’m pretty new to watching your videos, but man I love these. Super informative. I hope to one day have the knowledge on 2 strokes that you do.

I enjoy watching you troubleshoot. Don't sweat the negativity. It says much more about them than it does you. I enjoy your content very much.

Sounded more crispy immediately after the new jets. My son and I love your videos!

Does anyone else hear the grit / sand dirt when he assembles things. I’ve learned a lot about how to diagnose small engines and repair them. But O does he have a lot to learn about cleanliness and how to use the right tools the right way.

Important to note: Whenever using gasket maker or sealant on the reed cage,cases or head it must be a gasoline resistant product. Otherwise the fuel will cause it to break down, create an air leak then seize the engine. No fun. Great video. Thanks.

Miss mine. Bought it brand new and was the last race bike I owned. Nice to see one resurrected.

I like that grey permatex in the stubby can that's pressurized, makes great gaskets. Seal super tight too.

There's things I see this guy do that I dont agree with in many videos. I dont get on here pointing it out looking for attention. We all have our own way of doing things that will NEVER make everyone 100% happy. I turn wrenches a lot and work on a lot of 4 wheelers and dirtbikes . Im sure if I uploaded videos here , many folks would call me out on things. This guy has the confidence to do the work, record , edit and upload. Every single person that I've seen shit talk in the comment section , dont even have any videos uploaded let alone any dirtbike content.

There is a plastic piece that goes on the swing arm to keep the chain from rubbing. Also one on the bottom of the swing arm. I have a 1998 CR125 also.

That's the right set-up on that Kehan carburetor. like that it's off of A snowmobile engine. So it's going to be A totally different carburetor set-up than the stock factory style of one. So you're wrong on the jetting sizes for that carburetor though. Just saying those original jets belong in that carburetor for sure. I know cause the plastic piece inside of it those are inside of snowmobile carburetor's and jet ski carburetor's to. Jus like dirt bikes one also the only difference is the jetting sizes for sure. I went to A vocational school for small engines trust me it's 👍 right bro. Clean them out put them back inside and then try it out. I highly recommend cleaning out that entire carburetor first due to the water issues as we'll then retry it out.

Pipe is broke off in the silencer.weld it on were it comes in.

You gotta love the powerband when it kicks in. 2 Strokes!

Amassing job thanks for all your hard work, I learn so much from your vids

You might want to revisit that chain routing, Joe...

Check the float hight first, especially as it was flooding into the pipe, you need proper float hight, before you can jet and needle it properly, great buy man, nice bike, 👍🏻

Aviation sealant is better than tube UltraBlack , plus it has a brush on the cap for application . I used it on VW engines in the 80's and since it worked well, i use it for any seal job or gasket adhesive. Very thin surface height, solvent resistant, fuel and oil resistant. It has never dried in the plastic can either.

I had the same problem on my brothers rm85, just raise up the needle position and it should be good. It's always something small I noticed lol

The tube in the silencer is broken off. You should weld it back on to the pipe/cap going in. 🤘🤘

A super fast and easy way to remove gaskets is with a brass wire brush. I use it on my my grinder but drills work also.

Good Job Joe...can't kill those Honda's 🏁🏆

Ultra slick is hard to beat good stuff and the maxima assembley grease is good too and i love it has a real head gasket instead of o rings

What a shame, that bike has Black plastic's.. 93's had that almost pink plastic, one of the best looking CR's in my opinion!! Thanks for bringing it back to life!! A friend of mine had a 93' that had the same problem, I think it was the Stater and or flywheel???

Some 2 strokes have gaskets, others do not. I still have a large collection of 2 stroke motocross bikes without case gaskets. They each used their manufacturer's proprietary sealant. I've found a better sealant from an automobile manufacturer and have used it on all of them.

Those carpenter hammers sure come in handy. Wy invest in a ball peen hammer when a carpenter hammer is already near by!

Hi joe I’m lan from northern lreland love your videos have learnt heaps watching them love seeing vinny keep up the gud work

Tunning / Jetting ( GAS - Oil ) Mix along with Air Screw and Needle settings are a matter to be addressed both Separately and Together. Part of Checking to see where things need to be. Pro - Circuit and FMF differ from stock. LIKE the Changing of the Air Filter element. Are YOU running 87, 89, 91, 93 Octane ??? What type of 2 Stroke oil are you using? The Spark Plug could also need to be changed for the heat range. Hot - Cold - Stock - Etc. WHAT YOU NEED TO DO ??? One thing at a time. Get the Exact Jets ( PRO - Circuit ) recommends. Water in the gas or Poor Float bowl settings will cause different issues to be resolved. CHECK ( Double - Check ) Then Check it all again. a two minute test run will NOT Conclude or Exclude a single item. The Actual Running temp of the engine VERSUS Cold Start or Over heating will effect a lot in the tunning process. Mechanics and Tuners Rely on Actual FACTS Not Fiction. The Seat of YOUR pants or What it sounds like can vary greatly by location , altitude, and time of day with the Air quality being the ( Constantly ) Changing factor. Cold air - Warm Air - etc. Today you di d Part of the puzzle. YET, ( IF ) the GOAL is to get it ( RIGHT ) there is More work to be done. Start with the basics. Empty all the fuel out of the tank and the carb as well. GET Fresh Gas and watch the MIX as close as possible to be where it should be In the Middle of the range Not high or low. Verify the proper main jet, Pilot then set the idle screw and Needle accordingly. Warm up the bike without Driving it for at least a few moments. Then Shut it DOWN Wait about 15 to 20 minutes. Then do it again. After TWO cycles now let it warm up by itself. Sitting / Resting. See if the idle increases or if it starts to stumble all on its own. Shut it down and let it completely cool off. (IF) You followed what was Stated for the UPGRADES and have everything set PER the Manufacturer Specs. Consider what you did with the sprockets both front and rear. How a Bike takes off from a stop versus its running to top speed total will greatly vary by the Ratio being used. Its NOT important what came stock as it is what CURRENTLY is being used. To many front teeth versus Not enough back teeth. The BIKE will preform Different if each one of this steps is Out of Whack. TUNNING is a Combination of both Sitting and driving. This is a Used bike. The Previous owner could have switched out each item and made it work against the upgrade. See it all the time. I got a Del on this so I switched out that. No Worries it will all come out in the end ( WRONG Wrong WORNG ) Now before you go BLOWING off all that has been said ) REMEBER what it was and was NOT doing when you first got it . Each things builds on from the last. its like math. 1+1 = 2 ( YET ) 1 x 1 = 1 . IF ONE THIJNG is OFF / Wrong then you keep trying to fix something else ( IT WILL NOT be what it should be when you are not dealing with the WHOLE problem. Rule of Thumb. Adjust / change ( ONE ) thing at a time. before adding or taking away from where you are now. Look at what came on it stock. The Teeth Count Front and d rear. The Carb size and also the proper jets for the upgrades. Some Products will say. Tuning / jetting will be effected by adding these After market products. Ech step effects the next. Go through stock settings. IS what you are now trying to change the proper way the NEW products recommend ??? from what ( I ) can see on the internet. The previous owner did Little to Fix the problem yet added a lot more issues then what ( HE) started with. Ignore this Advice. YOU WILL ONLY BE ADDIGN MORE PROBLEMS GOING FORWARD as before....

The bike definitely sounds good. I definitely think it would look better with new plastics maybe even a new pipe and new grips. Other than that the bike looks good and sounds good but definitely think I could use new plastics maybe a new pipe and maybe some new grips. I love watching all your videos. Keep the awesome content coming.

Hiya Joel your lucky chain ain’t come off and locked up on you chain not running through chain guide hope you read this cheers 👍

you are the best Mechanic joe buddy wonderful video bro it's very educational I have learn allot ever since I start watching your video I have a 1998 Suzuki 350dr I will begin my project very soon all I need is some new parts

Man, I wish you had a vapor blasting cabinet to clean those parts like new before assembly. Great work By the way. Scott in Southern Oregon

this channel has to be some of the best content on youtube

Hey just a heads up on the chain routing. Route it through the chain stay you have it underneath. I love your videos keep doing what you do

Looks like you had an awesome time testing lol, heard the giggles.👍😂

The nut that holds basket sounds like there was sand in the threads? Or something gritty😮 great video joe

Sounds alot better after that jet change think ur right a little tweak on the needle and that bike is gonna be sweet . Anonther thing that may affect it is i don't know how much the repacking of the exhaust affects the recommended jets aswell worth a look into it

Oh yeah and as stated elsewhere the chain is on the wrong side of the rear guide. Love these vids man

On the mid-90's Honda 125's turning the choke knob till it idles leans out the pilot circuit. Back it down till it just dies from idle. No idle. Install a 1368 needle 2nd clip down. Much better bottom end.

Great job as always, i would let you work on anything!!! Very meticulous and you care that its done right!!!

there’s all this praise in the comments and nobody noticed he put the chain under the guide 🤣 yall must be amazing at working on your bikes

I have to say I have ZERO interest in bikes but I love your methodical approach to repair and diagnoses

Loving your content , if only the dude carried out and tested the gears with the socket like you did before putting back together you would of saved a ton of labour , on the flip side content is content. Keep up the great work. Greetings from the uk 🇬🇧

Great video as usual ! did notice you put the clutch on BEFORE the engine gear !!! been there done that myself ! lol

Bump to 165, good gas, good to go!! Great little bike, awesome video Joe!!

Check the bottom chain guide bud, otherwise good work, always lookin forward to ur next project, been watchin ur vids for years keep up the good work joe, cheers bud

I saw James Condon using a small razor scraper with a handle worked a treat to scrape gaskets

I know there’s the super scraper but some type of wheel on a drill will work

That chain need to go through the guide on the swing arm mate… great build

Also for small fixes like those hair line scratches near the front studs look into UV epoxy? Bonds to meatal real good!

100% the needle. I had same exact problem on my 97 cr125, changed needle position one click higher and ran like a champ

Joe assembly lube as extra additives and to much sticky stuff. Itll burn and melt away and then you'll be left with a sticky substance. What is better than assembly lube is STP oil stabilizer it's not as thick but does a great job. What's even better is lucas oil stabilizer its thicker and does not melt away like assembly lube

what I’ve learned is there are a lot of crap builders out here his work speaks for itself great work

AWESOME BIKE I'm learning so much just got a Honda 125 and a yamaha f450

Joe, I would love to see you get your hands on a Yamaha tw200. I think it would be right up your alley

that bike was crusty dusty and you fixed it keep up the great work

pro tip to any 2stroke head is hand true the head on thick granite or glass it`s amazing mod start with 320 and go to 1000 don`t go past any profiles

165 main, lower needle it should clean up that mid range, 162 main may be thin on the top. You may also want to read up on mikuni and khien carbs in your spare time as the carb circuits that control low,mid,top are very different in respect to when one circuit changes to another . Best of luck🙂

Idk if you know this old school trick if you use grease for the gasket like a carb gasket, in this case reeds. For example, if you ever had to change them, that gasket would be intact. Thats how I do my carbs for my car. I lather the gasket up. Allow it to sit for a minute or five, then put it on. I put grease on the front and back of the gasket, then place the carb on. I have removed my carb from my car more times than I can count. That gasket has always survived and looked like new.

25:26 To shorten down a chain you'd screw the adjuster bolts all the way in, move the rear wheel up and then lengthen/shorten/cut the chain. This way, the more the adjuster bolts are out, the more your chain is worn, indicating when you should replace it. That's what we motorcycle mechanics do. Also im not quite sure if you noticed but you didnt run the chain through the chain guide there (at the rear sprocket). For the jetting, i'd also say it's the needle position, try moving that clip 1 position up, that should definitely help, I'd recommend you take out the carb, disassemble it, clean it and put it back together, that way no specs of dirt are messing with the jetting, don't forget to check float height too! Without float height jetting is gonna be a nightmare!

love the videos! look forward to the day you pick up another 500cc

Amazing work once again man always seem to amaze me lol

take the tank, rear fender, front fender and put them back to white. leave the shrouds and side plates and seat black then youll have a cool storm trooper look to it.

despite the chain being on under the chain carrier nice work!

Damn bro u are a master mechanic that is alot of work u did hats off💯👍👌

If you put grease on those case gaskets, they won't stick if you ever need to take them off again. With the sprocket bolts, if you hold the allen head and tighten the nut on the back side, you won't ever strip the allen bolts out. Just the opposite of what you did.

I hope someday you will learn the Magic of a set brass wire wheels!! Great Buy!! wish I would have found it!🥴🤑

Sounds good Joe!! Tons of power...

the chain is outside the swingarm guide after replacement. not good.

A co worker of mine had a hand held RPM gauge . Yes the needle position check .

Brilliant channel always enjoy your videos 🇬🇧

bro you need to put the chain through the chain gard like it needs to be love the rebuild and lets bring back 2strokes

For removing gaskets you should try some of those less or non abrasive wheels for a drill or grinder you can find one that works idk what they are there made from some rubber or compound but there’s a way with no razor blades

Another one saved. Good job young man.

Was there ever a doubt,,Nice job as usual
