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.

[@billhenry7833]

Thank you captain obvious

[@travischapin886]

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.

[@BoxingLegends2024]

Thats because WD40 is a (water displacer) "WD" lol not penetrating oil

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.

[@laurencehastings7473]

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.

[@ladyjedi3D]

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.

[@scotttaggart71]

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.

[@steveperyer4850]

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.😊

[@scotttaggart71]

Also, synthetic oil will push thru Cork gaskets.@@steveperyer4850

[@user-uu8uk5oo4o]

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 😂😂😂

[@derrickgreen9020]

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.

[@davessparetime83]

Look at when you took the shift spring off. The spring was on backwards. Steering bearings? What about rear shock? Measure the cylinder bore.

[@keyper555]

I seen that too, good observation

[@scottgrahame795]

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.

[@donaldblakley6796]

You do amazing work and you are always calm. I respect your methods:) I have never missed a video

[@JoeTheBlacksmith13]

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.

[@JoeTheBlacksmith13]

Just realized the coolant impeller was trashed. That’ll do it too obviously!

[@BoxingLegends2024]

DONT REV THE PISS OUT OF A COLD 2 stroke! In fact when fresh start up DONT rev it at all! lol

Joe the broken water pump shaft cooked piston ring. Good catch on shift spring! Head gasket failure for sure. Don’t forget headstock bearings.

Ol' Joe loves his dirt bikes. Rear spring shot? Looked a little bouncy. Great video, always a nice day for a ride.

[@2vintage]

Little bouncy haha

[@jetstreek17]

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.

[@bager1246]

read the label .it is

[@chernorizetzhrabar1313]

WD-40 is basically diesel fuel with some additives or without. It's not an oil for sure.

[@memorris2]

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]

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, 👍🏻

[@eddyb6790]

Great video. Don't forget to order (or fix) plastics.

[@bmusic0912]

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!

[@tuscaroradave]

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!!

Thanks Joe

[@user-MotoZhelezki]

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

[@scottmoodysr9449]

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

[@rhiantaylor3446]

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.

[@derbi75]

35:13 That was classic. Spraying penetrant on the bolts AFTER almost breaking them trying to loosen.

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... 😉😉😉

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.
