I noticed that head gasket was copper so you could anneal it to get it pilable again. Heat it with a cooker or gas torch until cherry red then allow it to cool naturally. The copper will be annealed again and good for next use. You can do the same with copper crush washers if they are in good shape. They work harden over time and annealing makes them soft again.

[@davebarrowcliffe1289]

The gouges in the piston and cylinder port aren't disastrous. Two new piston rings and a few new gaskets, this dog is good for another 20 years! 🐶

[@hotrodgavin6543]

It runs so good because it was made when they actually made things last

[@Obamabruh]

This is true but I somehow managed to blow my 84 kx80 🤣

[@Yz4Life]

Haha because it is a little air cooled 2 stroke that makes about 15 horse, not much that can break on it lol

[@eduardsfarmgaming6092]

Same I have a 2006 yz85 rings is bad almost no compression but if you bump start it it runs nice just a little bog

[@shithead]

How many bikes you see on the road from

[@frankcastle7299]

I agree! They don’t make things to last anymore.

[@dekon70]

As old as they are the IT and KDX are awesome trail bikes. Both are absolutely bullet proof as you have shown with the IT.

[@daynasmum529]

KDX was bullet proof, IT was junk

[@timothytopping6099]

I am seriously impressed! I love watching your videos please don't ever stop!

[@emmettvonflue1827]

Try a Yamaha blaster cylinder and piston. With a little modification it could probably work. If you want I can even send you the specs for the stud holes to see if they would line up.

[@comedyash]

What an awesome revival really goes to show how bullet proof these old 2 stroke motors are they were built simple and reliable, hope to see this bike on the channel in the future long live the 2 strokes!

[@peteraitken6494]

Haha unbelievable can’t believe that ran joe kicked it it into submission right enough lol awesome mate hopefully you get some parts to repair it properly great video man 👍🔧🔧🔧👌

[@SeanSR]

That was an amazing video, cant wait to see part 3 with new piston and correct carb/jets. Keep up the awesome work, great free content.

[@kevinAuman1]

I swear that tiny little bent screwdriver is probably your single most used tool ever! Hahahaha I believe it makes an appearance in every single video you've ever made 🤔🤷‍♂️😝🤣

[@tomkruze2749]

My older brother had an IT175. Was a nice bike

[@Hondanissanman]

It puzzles me how some people could put a 2 stroke piston the wrong way?. Arrow on piston always towards exhausted port 👍. Great work and great video 👌.

[@justinthymes5680]

Right on!!!! That was an exciting video! I'm an old dirtbiker from the 80s and really dig your channel. Cant wait for the next one!!!!

[@Changesforever7878]

Done some research and the IT200 shares the same engine parts of the blaster so you should be able to rebuild that bike man I only wish I could find a bike like this

[@timcowger6318]

I think the Blaster 200 is the same engine and parts will swap out also.

[@jax8646]

Revving the thing out and everything, amazing work

[@keithcrampton1438]

THIS GUY KNOWS HOW TO TURN CRAP INTO GOLD HE'S GOT THE MIDAS TOUCH!

[@migliaman]

deserves to be rebored and it'll go again, show it some love man! it wants to go again, they never die these old strokers!

[@thunderroad7289]

We and my buddies used to ride those IT Yamaha bikes back in the 80s . Had a lot of good times riding those bikes

[@Miguel278mx]

yamaha in that age was rock solid parts!!!!

[@alexandermorris2335]

Yamaha in general. Even modern yamaha's are as good or better than honda's, reliability-wise. If only they could fix their suspensions though.....

[@AdrenalineRushMX]

@@alexandermorris2335 what wrong whit the suspensions lol

[@mikehudg2209]

I love it Joe 😀 work with what you have !! Single ring easy install dude !! Awesome little bikes , very reliable, 125 top end will work to if you find one .. very fun and entertaining video 👌👍👌👍

[@kurtyoung6769]

Wow, I cant believe it runs that good. If I were you I would run 20 to 1 oil ratio.

[@MrTaylormadetech]

I cant believe the thing ran and well... seems 80% of the compression comes from the piston itself... i would have thought it would smoke horribly or run with really low power ... but it looked like every other old dirt bike in the Caribbean.

[@harryburford6629]

well done mate, whats the banging in the back ground is jade building stuff? good vid and a surprise..

[@JohnnieBravo1]

Hey Joe; at least the gouge in the piston, and gouge in the cylinder are on opposite sides now ;-) BTW, check out Dale Sweger's youtube channel. He does all sorts of fun stuff on old 2-cycles, especially Yammy's. He has videos on modding cylinders, increasing port sizes with die grinders and stuff that may apply to your bike there. (he might even have a cylinder like that laying around). Awesome stuff you got there.

[@jimmymckay73]

I just found Dales channel last night. Subscribed immediately.

[@TWLML420]

Back in high school I had a 1979 IT 175. She freaking ripped!

[@michaelmays9292]

I bought a 1984 CR60 and the dude that I bought it off of didn't get one of the C clips in good enough and it fell out ,he said he want about 30 feet and it locked up . I tore it apart cleaned it up got the rings unstuck ,put it back together and got 155 pounds of compression, that was after I bought a running engine off ebay for 168 bucks

[@Matt_Holcomb]

Dude this made me smile. I got a dt175 actually how I found your channel. But the cylinder and piston were scored too crap. The lower ring was stuck I filed the ring land and got it free put it together and it ran wouldn't idle n drilled the intermediate and it idles now lol m gonna get a top end kit on Amazon n I'll be back lol

[@dg8676]

You have an amazing gift my friend. I just bought a 90 Honda xr250r it’s getting work done please send your blessings to my bike🙏🏾

[@davesplace1307]

Very educational on this one joe! I love it. Would like to see you take it out to the property and give her a proper full send. See how long itll really last

[@brianstractorshed2759]

Pretty awesome you got it running, any updates on it? I bought one complete in but in pieces and look forward to making some noise with it!

[@ianelliott425]

Wiseco should have a piston kit and i believe the jug is boreable up to .080. The jug should clean up with that. They sell sizes in increments of 0.010 usually. The bike looks identical to my 1982 IT175J. You should bore it out and woods race it.

[@callmecardo916]

Pretty cool how you got that bike to run the way you did, I dig your land and trails keep ripping👍🏼👍🏼

[@sulliandtylergarage1745]

This video is sick, its a perfect change of content to destruction but the same category as you normally make, and i bet even after all that put a new plug it in and maybe some rings and it'll still run again 😂 love the vids keep up the good work! Edit: if you ever do wanna try and restore it i think the early yamaha blaster cylinders will work with it because i think there the same size

[@Bri-tg6xr]

Pulling a Soichiro Honda by making your own pistons, awesome work!

[@karl6823]

Damn i can’t believe it runs, nice joe!! When you rev it up damn it sounds like a blaster!!!

[@Korobase]

Hello from Portugal!! Been learning a lot from your videos, great channel :) can you share what is the accessory attached to the electric drill you use to smooth the inside of the cylinder? thanks in advance.

[@melfletcher2315]

That's very interesting, I'm surprised that it ran reasonably well. What are the old XL Honda in the background, with no motor, and the XR Honda I think it is? It would be great to see your collection please mate

[@rcsendandblast1579]

One Ring Working WOW. That’s amazing to say the least 🤘😎

[@mrsandman5679]

You should give it a new piston and rings and new gasket kit. Jet it decent and get the right slide for the carb and that bike Will actualy run better than you think. You should clean up the plastics abit to and allso do a topspeed run on it. If you drive it with piston and cylinder like that i would mix abit more oil with gas just to be on safe side!

[@johnbest4320]

These are great bikes so well made and a ton of fun when these were made they took pride in making things last

[@murrayminimotors1674]

Great content!! Do you think a Yamaha Blaster top end would work!! Or maybe just a sleeve from a blaster??

[@mrhzk35404]

I just posted this. Ha ha. Looks like they are interchangeable.

[@staygold902]

Similar but different stroke I believe

[@troyroberts7514]

I was going to say the same thing I own a blaster 200 and that wall looks the same

[@stoneyoutdoors8819]

thats amazing, didnt think it would even start like that, makes me wonder why i rebuild over little things now lol

[@edjacobson8480]

You don't shy away from a difficult job. Much appreciated.

[@yamit465]

Check for air-leaks with WD40 - brake-cleaner works too, but it's too harsh on rubber and paint.

[@robertdavis4184]

Could you take the cylinder to a machine shop to see if the cylinder can have a sleeve it to save it. If so then call wiseco piston for a over sized bore. Just in thought. Then rejet the carburetor..

[@garageassembled4701]

You passed that off to a unsuspecting 16 year old with a $1000 bucks didn’t you! Anyways it was running and you got your 1 ring video! Good job reviving a old friend!

[@smallmiraclesgarage622]

advanced sleeves is a great company and fast turn around. only company i use to have my cylinders resleeved.

[@billmarty8526]

Snowmobile season is coming!

[@jimtitt3571]

Loads of race bikes only have one ring, 125 and 200SX KTM's for example. We ran the 465/490 Yamahas with only the top ring only until Wiseco brought out a single Dykes ring piston and then Yamaha made one. The only downside is you need to change them more often but on a race bike it doesn't matter.

[@JC-db4ih]

I love this type of vid budget build thing ripped!

[@christopherk111]

great job well done,,very inspiring ,,greetings fron australia

[@Clearanceman2]

I haven't seen most of the video yet but I wonder if you could use a YZ cylinder and piston. Maybe slightly different CC but if the cylinder fit and the piston fit the cylinder it might work. You could probably take that cylinder and piston to someone who was good at TIG welding and they might be able to fix them.

[@paulroberson5094]

Those old dirt bikes are Kick-Ass

[@steinaroskarsson2307]

IT are solid bikes

[@JoshuaEagle1080]

Great video Bro, as usual! Keep up the good work!

[@onthecheap1292]

Hey man..You need to prefer parts for a Yamaha blaster- atv ..Same cylinder/head/piston /rings/gasket kit all identical

[@18wheeler77]

I don’t get why they don’t make piston rings that wrap around like twice around, kinda like a very short spring. Wouldn’t that be like the equivalent of having two rings? Wouldn’t the compression be way better? Wouldn’t it create a better seal?

[@mikebruce3198]

Are you restoring these bikes or just trying to roach them together ?

[@306GokartsCustomBuilds]

Awesome work..i have same bike probably in same condition..whats the inlet on the intake boots for?

[@toxicwaste3120]

That's insane 🤣 good job brother

[@lucasalbis2260]

You can sleeve the cylinder if you want, probably would run around $350 in the states idk I’m Canadian

[@b_wilk98]

I had a 1982 Yamaha IT250. I rode it for months with no issues except for the Carburetor Intake Manifold. It was cracked, and had been "repaired" with Gasket Maker which was causing a massive air leak, and I was unable to tune the Carburetor properly. I finally found a company on Ebay that made replica Manifolds for $120. I eventually traded it for a clapped out 2010 Yamaha TTR-230 after I realized parts were hard to find/expensive for these old bikes. The boy I traded it to was riding it, and it blew up on him the next day. I honestly didn't think it'd ever blow up. I question if he didn't mix the gas properly, and leaned the top end out too much as these old bikes require a very rich mixture (20:1).

[@b_wilk98]

IVE GOT SOMETHING SPECUL 4 YUO HOSS!!!! 🖕🖕

[@capeRCouple]

i agree with other commenters,bore the engine and port it,you will have a good engine again.I had this done to a couple bikes in my time and they worked amazing.This would be a powerhouse bored out,my old stock it200 was fast .find a machinist locally and bore that thing before you totally destroy it,they are getting harder to find these bikes.

[@simonlines9618]

Joe u have the patience of a saint u have that never say die attitude witch u need with two strokes 😅 two strokes wind me up -- top video

[@johnbest4320]

Mate tinker with it and source out the parts if you look about and ask it is a bike worth having in your collection these bikes are fun

[@jeffserene9954]

Gosh, too bad I didn't see this sooner. I have a perfect cylinder for an 85 IT 200. Along with a spare, complete! runner motor.

[@Hanky_Bannist8r]

Those old machines are tougher than a $3 steak. It's pretty cool that you got it to run with a bum top end.

[@kernelbadness]

Dude send the cylinder out to get worked. The right shop will supply everything you need.

[@powerbomb400]

You should be able to get a new sleeve for the cylinder. Suzuki at one time used a single ring in the RM's. Had to be rebuilt like every 10 or 20 running hours. I thought the Blaster motor was same as the IT motor.

[@crazycarl6922]

I had the same bike and was planning on buy this one

[@tonyshepherd406]

You can fix anything-recreational !

[@robsmith1752]

Reminds me of the Yamaha blaster engine awesome content always

[@jayjudd6518]

Ho Lee Chit you can’t stop a 2 stroke. Fun rebuild.

[@craigmorgan4676]

It's gonna b a good 1 Joe,gl brother,looks like u gonna need it!😫🤔😱😱🦵🙏🙏🤔

[@laxfan1238]

i hope theres another part 3 coming out soon. add another ring and maybe some decals

[@judithtreurnich5744]

I agree with you, try the plug

[@calebcarinci2428]

Those old Yamahas will run in any condition

[@larrywarner9314]

Quick tip use a torch or a heat gun on stuck piston rings

[@Crosshatch1212]

They things go for crazy prices in uk .

[@DJswope73]

Ready for this one🤙

[@ingoegal1405]

Kann das sein das du die Schwimmerkammerentlüftung verschlossen hast? Maybe you should`nt have closed that hole from the carb ;-) I love your videos , awsome bikes

[@dereksmith8864]

If you can find parts do you plan on restoring it or getting rid of it those are a cool piece of history

[@lbdrummer3]

That's pretty crazy. Maybe take a dremil to the port and open it up a little bit to get rid of the chipped area. Put a new piston and rings in it and send it!

[@jmendo2546]

Blaster is based on the it200 use the blaster cylinder they real cheap on ebay. ***** I say it every time and u never listen or try, use heat and piston ring pops out ring I use a torch but oven might work as aluminum expands and contracts at differant rate

[@shartne]

Use copper head gasket spray by permitex on the head gasket.

[@nathanpeever6701]

I bet a cylinder and piston for a blaster would work for an it200

[@DeveroyB]

Joe you should always leave the airbox off so that you can choke it with you hand ✋️ when your hand gets wet with fuel you know its getting fuel

[@MDHenry4]

What cool beast

[@SmallTownShenanigans]

My 93 rm125 does the same exact thing where the clutch slips and won’t grab bogs out when you go on the throttle more then 1/4-1/2, and revs itself out. It’s inconsistent and when it’s there it’s very noticeable and barely rideable(have to hit the killswitch so my bike doesn’t blow itself up😂). Took my clutches out they r shot, gonna replace and hopefully that fixes the issue

[@shrugger1]

I definitely learned something. Only buy stuff with available parts. lol

[@chadbrown6444]

Wonder if a blaster cylinder will fit it

[@robinbrowne5419]

Cool video 👍 I bet on 120 compression. I changed my mind to 135. Oh geez. I was right the first time. Cheers :-)

[@tomerdook79]

hello, please help: i have stock Honda crm50 . i usually ride one day at waek for 1 hour . i want to put a big bore kit (70cc) the question is if the stock crank will not damage?

[@_helix0150]

try "pole position high speed 2t" oil on your air cooled two strokes

[@peteweisenbach5642]

send it to Powerseal USA in Pottstown PA they can replate/coat that cylinder good as new

[@brucesizemore739]

I believe that motor was the basis for the blaster motor. See it a blaster cylinder will bolt up.

[@triggeredmonkey3439]

An old trick to unstick a ring is to boil the piston in oil on the stove. Not boiling like water of course but get the oil as hot as possible usually the ring will just pop out on its own if not you may need to pick at it as soon as you pull it out of the oil. This trick has never failed me. Why not send a cylinder and have it sleeved?

[@barnsley1066]

Yamaha IT175/200 or a Suzuki PE175 are my most favourite bikes of the 1980's.

[@chefbobbysponge3833]

One ring to rule them all!😂😂

[@ronaldrecord3011]

See if you can get a sleave at stock bore for that and have the cylinder board and have the sleave pressed into it
