This is my favorite Chanel to watch bike rebuilds because you always buy projects that a regular person can find on marketplace, and you approach the problem linearly by walking the camera through the steps of diagnosis.
Joe, Just a suggestion. PB Blaster or Kroil Oil or Aero Kroil for penetrating oils. In my 53 years, I've found they work the best. I gave up on WD-40 years ago. And yes, the guy wanted beer money, indeed. At least you can save it and make it run great again, like you always do.
This channel is a big help for me Joe. I just bought an 89 kx125 last week with water pump issue. It’s convenient watching you work on the same bike as me simultaneously.
NASCAR found out about how with synthetic oil in the differential on the cars, the fears would not seat and wear in l. So they would use regular gear oil to seat the gears in by running a few laps, then changing the oil to synthetic.😊
You seat rings properly by doing a good break in He named all the parts in the transmission that could be bad and then he says it might even need a new transmission 😂😂😂
If i had to unload bikes by stepping off the tailgate like that....i think my hips would break and id fall backwards and the bike land on top of me hahaha
Had a kx 85 in the early 90's it ripped for a 125 especialy after new rings were fitted, looked the same as yours, great little bike, i then had a 86 kx 250 after, and that was a propper ripper too, then a 86 cr500 scary beast but loved it, best bike ever, wish i still had it 😭, love your videos Joe, 👍🏻
Do the Taryl Fixes All "heat and quench" trick on that power valve shaft. I had that same exact bike back in the late 80s. That was a fun little bike!! Great find for $400. Great video too. That cylinder would be a perfect example of something where a parts washer would be handy. If I knew where to send them, I'd ship you a ball pene hammer set. Love your channel. Keep em coming!!
Great video! I notice something though. On all your bikes, even newer ones, you check the VIN numbers. If you had a title you could avoid a potentially bad situation with a sketchy guy. Like the guy who wouldn’t let you kick the bike over. He could say, without a title, you stole the bike, and have to give him the bike and he’ll keep your money. The videos have really helped me learn more about my machine!
Very interesting alternative to car mechanics. I once bought a brand new Cagiva ‘Super City’, like the start of that James Bond film but red not camouflaged. It never did change gear properly from new, showing neutral at traffic lights but sneakily still in gear so would embarrassingly stall. It looked the part but I sold it.
Just a quick note today Joe. Remember that WD40 is not a lubricant, but is a solvent. it helps break down grease and oil based substances, but you need a penatrating oil for getting in and losing bolts, along with heat.. Thanks for the content.
Wd40 was made as a water displacement for the inside of rockets. But it IS NOT a lubricant. Its great for dissolving rust and penetrating into bolts and threads, but it not a lubricant. Its a penetrating oil.
@bager1246 im reading the can.....it says "stops squeaks, removes and protects, loosens rusted parts, frees sticky mechanisms, drives out moisture." Thats ALL its says. Maybe YOU should read the can, buddy....
@@steveww07 because he just does partial rebuilds & resells them anyway! hes the same kind of seller he buys these bikes from! Not once in 10 years has he done a actual REAL rebuild! everything is a budget build with parts that wont last a month!
Excellent job, as usual. I always learn something watching your videos. That poor Kawasaki has had a rough life. The owner must have known about most of these problems. You probably could have bought it for $200.
Ideal bike for you to work on. I think you should think about how much changing the silencer and even the piston will add to the value of the bike - it ran quite well as it was and a new ring and light hone and polish of piston will bring up the compression to a reasonable level.
The wear on the piston is indicative of a partial 4-corner seizure from warming up too quickly. That’s what happens when the expansion of metals heat up too fast, and therefor, unevenly. Warming up slowly, gives the heat time to dissipate from hot spots and heat up more evenly overall.
Your channel is a treasure trove of mechanical knowledge and I really just want to say thank you! Channels like yours are teaching me something new all the time and I'm super grateful for that.
Man that bike brings back some of the best times in my life. I had the 86 kx 250 and man did i have fun on that old bike. Thank you for the video. It really brought back some good memories.
hello! I liked this kawasaki. I liked its color and this vintage design! I will be happy to watch the 2nd part with the assembly! The gaps in the intake valve are not a significant malfunction. under pressure, the tabs are pressed against the body
my favourite channel on youtube,a big fan from the uk,up the vintage rebuilds,learning a thing or two also,what a bargain for 400 bucks,i hope its an easyfix
Whenever I have a stuck head, I hit it like you did but ill take recoil rope and stuff it through sparkplug hole and GENTLY turn over engine to help push off the head.. give it a try next time Joe. Sweet video brother
I hope that you clean this one before you put this all together again and maybe give it some black paint .✨ I would say cleaning with a pressure washer before tiering it apart but that is too late now, Maybe next bike.😉
Hey that's a sweet bike!! Easy fix with the shifter spring in wrong. You will the top end sorted out, and muffler for it and the other odds and ends. Like you said for about $300 or so. And have a pretty fast Kawasaki. Love it!!!
It’s been said that…. No new vehicle can leave the factory until your dog has given it the seal of approval, it can be then stamped with a “VIN” number 🤣🤣
You have this 4stroke habbit of taking 2t heads off for no reason and it shouldn't be advised as good practice. If you have a leaky head or you need to clean it up from proken ring fragments, OK, otherwise why break a good seal for no reason what so ever? You do this over and over again, in so many bikes and I'can't remember one that it was necessary. Just take the cyl off with the head in tact.
New at your channel, it appears to me that bike riders are no different than those that drive cars. Put the key in it and face forward..put gas in with no pm at all. I had a BSA 650 rocket 3 that really ran great until i layed it down and busted my leg and side cover...i was a rider for a short time. Decided that bikes were not for me. I am anxious to see you get the BSA 500 back running again. Good channel.
Watched virtually all your videos and been a biker (in UK) for 56 years however, if you jet washed the bikes before starting to repair them you wouldn’t need to wear gloves 😂 Great Bike BTW 👌
Sorry to say it but intake manifold is 150$ in usa and 300$ if you live in europe. 1986-1987 were rare and parts are rare to. Good luck with it. I got a 86 aswell that i am restoring. It is probably worth to put the money in to yours if you get good deals. For a good running one that looks okay you get 800-1250$ and in nice condition 1500-2200$
I knew that intake was not gonna be as cheap as he thought. I imagine someone has remade them by now? We used Alumilite epoxies and made some for Honda ATC's, even epoxied new magnets in the old KXT Tecate flywheels. That was a problem back in 84/85.
Well not bad Joe. I probably say that water pump went out a while ago and it overheated a bunch of times the way them bolts and power valves rusted out. Put some heat on that power shaft and tap it with a punch. I get it out and get the rust off all that and replace them seals. You need a vapor blaster to help you revive them parts for you without tearing them up. But all in all you gonna make out one way or another with it... 😉😉😉
This right here!!!! This was tested against the popular ones I.E. WD40, Kroil, PB Blaster etc. (P.B. and Kroil are top tier) but ATF/Acetone mix bested them all!!
what do you do with these bikes when you're done? flip them? have you thought about doing partial restorations so you can present a better finished product? probably not what you intended starting this channel but its definitely something I'd pay to see
hes been doing this for 10+ years already he fixes them to "bare minimum" and sells them he has absolutely NO intent in doing even "partial" restorations! just budget buys & budget builds
no wonder why he makes it look so easy. seems like he's picking up a bike every couple days. I'm just selfish and would like to see a polished bike without having to do any of the work😁
Motion pro makes a awesome piston pin remover w/lots of varieties of size vsffdpin out through the is pins to screw on so it will slide the piston. I have the knock off brown or bronze colored one and it’s awesome
My OCD noticed that the drive chain split link retaining clip has been fitted backwards at 27m11s in. You might want to change that round so the open end points away from the direction of chain travel..
I really wonder what Joe does with the fluids he drains out of vehicles. Since it appears he just mixes the coolant and oil in the same pan it doesn't seem like they could be recycled normally. I find that to be a bit of a bummer.
Yes, this is how u should buy thing's. Not with intent of getting it no matter what the seller is selling for or the Bullsh*t story they say "Just need's carb cleaned". Because you are teaching not only how to rebuild stuff but how to get stuff at reasonable price with repair cost in mind. Not to just blindly, pay full wholesale price and have way to much into something. You have to alway's remember your running a *Business. And follower's New at buying and repairing are watching and following "Your Format" you have 423k subscriber's and other's just watching.That's why I have been tough on u in past, I alway's see the whole picture/angle
Man brother your going to have to check these bikes out better before you ride them....yikes you was riding that thing......lol😂....nevertheless nice find......👍🏽🔥❤️💯 You win some you lose some it always feels good on days when you win!!
I really enjoy your content bro and I have learned a lot from you. I make sure I watch every minute of your videos and purposely click on ads. Please don’t ever stop making content 😁
This is where a parts washer would be so handy - just dump the entire top end in and let it do its thing, and it would save so much time cleaning things up. And boy, does that thing need cleaning up.
You would be surprised what just replacing the ring would do to make that run really good, but a new piston comes with rings anyways but people in a tight budget can easily get away with just a ring replacement for like 40 bucks.
If the impeller wasn't working while it was running that would cause the piston to partially sieze causing the damage and causing the rings to wear also
I learned some stuff about a 2-stroke in Thai video. I want to get into one but I’ll have to know how they work. Not familiar with power valves and reads.

😂😂😂😂
😂
Thank you captain obvious
I havent seen this style before
@ 4:28 The piston is scored because someone doesn't do a proper warmup before revving it to the moon!
and no water pump
Is his name Joe ?😂😂😂😂
I've learned lots , starting to guess correctly about things ...tks Joe
Joe, Just a suggestion. PB Blaster or Kroil Oil or Aero Kroil for penetrating oils. In my 53 years, I've found they work the best. I gave up on WD-40 years ago. And yes, the guy wanted beer money, indeed. At least you can save it and make it run great again, like you always do.
Thats because WD40 is a (water displacer) "WD" lol not penetrating oil
Guy wanted beer money instead of xwifes bike. Good deal
Lol
🍺👍
Buy the YZ80 in Marshall, wi....it just needs a carb clean and spark plug! 😂
This video is now Sponsored by WD40!!!😎👊🏻
Thanks for the laugh. 👍
Made up for the lack of kicking in this video with heaps of no load revving. Good man
He will never learn
@@ctbale1he's too OCD and overload revving is childish
Oh yes I remember now he does not know how to shift a motorcycle it's really hilarious it's actually sad on the poor motorcycles he buys

@@ctbale1 Hundreds of people been telling him and he still does it, thats kinda insane.
This channel is a big help for me Joe. I just bought an 89 kx125 last week with water pump issue. It’s convenient watching you work on the same bike as me simultaneously.
That's an old style piston for sure and well overdue for replacement. Amazing what a bit of TLC con do! Look forward to the 2nd part.
I just learned, synthetic motor oil, works so good that it will not allow piston rings to seat properly, during brake-in. I like your videos.
NASCAR found out about how with synthetic oil in the differential on the cars, the fears would not seat and wear in l. So they would use regular gear oil to seat the gears in by running a few laps, then changing the oil to synthetic.😊
Also, synthetic oil will push thru Cork gaskets.@@steveperyer4850
You seat rings properly by doing a good break in
He named all the parts in the transmission that could be bad and then he says it might even need a new transmission 😂😂😂
I am always amazed on how easily you get the bikes down from your truck. Your legs are super strong.
If i had to unload bikes by stepping off the tailgate like that....i think my hips would break and id fall backwards and the bike land on top of me hahaha

I remembered my first 2 stroke KX rebuild. I found out the hard way that the power valve shaft nut was reverse threaded 😅
😂 what does that mean???
Ol' Joe loves his dirt bikes. Rear spring shot? Looked a little bouncy. Great video, always a nice day for a ride.

Joe the broken water pump shaft cooked piston ring. Good catch on shift spring! Head gasket failure for sure. Don’t forget headstock bearings.
no revving the piss out of it when its cold seized it
Good substance, good price. This one looks like it's going to be an allround winner. When you consider the age of the bike she's in great shape.
35:13 That was classic. Spraying penetrant on the bolts AFTER almost breaking them trying to loosen.
? spraying before you break em loose you have to wait, he was spraying after so the threads would make removal easier.
I like the carpenters hammer, where's the ball peen and brass punch bro!!??
@@dc6233you dudes are weird, watch the video or not 🤫 🤐

Look at when you took the shift spring off. The spring was on backwards. Steering bearings? What about rear shock? Measure the cylinder bore.
I seen that too, good observation

DONT REV THE PISS OUT OF A COLD 2 stroke! In fact when fresh start up DONT rev it at all! lol
You do amazing work and you are always calm. I respect your methods:) I have never missed a video

Vinny tells you check that trailer Tire
This was one of my recent likes…this was a job to see: I found it so interesting all the different corrosion issues and yet it still ran.
I like that zip tie on the fuel filter 😂
After overheating and seeing how hard it was to get the piston out I would check to make sure the cylinder is still round.
Over heating by the previous owner or by this nitwit knowingly riding it around and cold revving the shit out of it with no coolant
Love the sound of the 2 stroke. Brings me back to the old air cooled days.
Love your channel...I watch it on the big screen in the living room.

This bike seems hobbled by not enough travel on the suspension. And no power. Plus not shifting.
Hey Joe, Don't forget the headset bearings... also, that rear shock looks like it's riding pretty low.
My ‘78 DT Yamaha 250 had a ring that broke in 2 pieces because it was so thin opposite of the gap. Quick hone and new ring and it ran great.
A concoction of 50% Acetone and 50% Automatic Transmission Fluid makes a pretty good rusted hardware loostener. I've used it quite a bit.

When you work on these older two strokes do you repack the silencers??
does that piston not have a locator pin to stop ring from spinning
Great bike Joe., can't wait to see this one get fixed man
