Thank you for all the support!
Yeah crank seal or somehow a broken case was the only option. Next time try taking the bearing out of the clutch pressure plate. As long as your clutch plates are good with the springs still in place and putting tension on the plates they should hold the basket along with the pennies trick good enough to remove the basket bolt, also the bearing support area helps keep your socket aligned. Another tip because I understand not wanting to tear the bike all the way down is to put the bike on its side and pour some premixed through the main bearing stand the bike back up and rotate the crank to mix up the old oil in the case then tip the bike to the other side dumping it out a few times. Sure it will burn out eventually but may cause your plug to foul early leading you to think theres another problem. As well as that is just to much oil for the rings and cylinder and gear oil that has all sorts of metal and fiber contaminants wearing you top end, crank and main bearing faster.
Sounds a bit lean but it can be the dings on the expansion pipe for some reason on the smaller 2 stroke bikes these small dings definitely restrict it all low idle till the power valve kicks in an just hits power as it should. But none the less another good fix Joe. I’m working on the quad zilla and a blaster at the moment but the dam blaster is being a real pain with the tors and break over ride which I hope after removing will finally fire up
@@978twostrokegarage2 the CR 80 doesn’t have a power valve
This may be off topic but would you like a old air compressor? Is gas powered and I think all it needs is a paint job, I think it would be pretty cool to see you restore it!
just a heads up i almost always put a thin thin coat of RTV sealant as requested in most manuals for most engines around the outside of almost every seal, not to seal anything but to hold the seal in and considering you found one popped out i would have put sealant on it to ensure it won't come out again and also always put a coat of engine oil/2 stroke oil on the inner lip of the seals so it doesn't wear out pre maturly
I'm an MMI grad, 22 yr Air Force vet. I have my own OHV mechanic business that works out of my home shop behind my house and you wouldn't believe some of the rediculous stuff I've had come in. Your doing a good job and I do enjoy watching you work on them. I started off bout like you finding old stuff and fixing it up. Great job man, keep at it!
I’m in school I asked my teacher if I can come to the restroom just to watch your videos😂now there goes 35 minutes of entertainment
Hahaha
And you likely learned more with this video than in class that day.
@@2vintage true
@@27Zangle exactly😂
this guy poops
You inspired me to start getting into mechanics and doing this stuff love the vids🙂
Yoo we do the same thing just subbed!
To the 1%reading this: stay safe, and have a wonderful day! ( My Dream is to become a popular moto vlogger) Thanks! ✌
Best advice I can give is don’t get discouraged and watch others if you learn good by people showing you how to do things I would watch lots of vids on how to do things it really helps you will learn how things work if you take your time lol
@@supermairo1716 thank you
@@Builditathome-Restoration thanks
For your frozen clutch bolt....next time try mixing transmission fluid and acetone (50/50) into a hand spray bottle. I learned this from an old mechanic. I had tried PB Blaster, penetrating oil, heat, and my car tire air impact wrench and still could not get my frozen bolt to loosen. Spray this mixture onto the bolt and allow to soak overnight. If you cannot remove the bolt the next day, spray it again and allow to soak overnight again. It took me several days of application but the bolt finally came loose. The old mechanic said this is how they did it back in the 1940's. Apparently, as the acetone evaporates it "draws" the transmission fluid into the bolt threads and loosens it. Hope this helps. Thanks for the great videos.
The quality of your videos are much higher than much larger channels. I love how you show the reality of working on old machines.
Dude you have all my respect! You have fixed so many bikes..you have taught me so much. I have xr75's,80's,a yz490,sl500,yz250,yz80,sl100..im determined to get em dialed in. Keep it up youre guru status..im 58 still learning the resto motor tricks ha ✊✌
Yes he's come a long way! It pays to watch as many channels as possible on working on bikes, ATVs etc. Take "mechanical classes" @ your nearby Community College if you can too.
this is what happens when owners use impact guns to do bolts up rather than using a torque wrench!!
I love your videos!! Very entertaining and informative, great job 👍👊👌
I like the idea of putting 2 hours earlier but I know this took way longer to fix than 2 hours lol. Good job man
I need to do crank seals on a chainsaw of mine.. I know it's the seals, because I've literally gone though everything else imaginable.. Even replacing the top end.. It lacks power and is unresponsive to any carburetor tuning.. Awesome job on the Cr.. I've ridden one (same year) back in the day.. She screamed!! I've really seen you progress in the years that I've been watching you.. My son exposed me to your vids.. Good job dude!! I've got a garage full of bikes myself.. About a dozen!
love this channel! you fix all the bikes me and my friends used to ride back in the 80's here in Canada. My brother had a kdx175 that I learned on when I was 9. My buddy had a cr80 and he would smoke me on my XL100. When we got older, he got a CR125 and I got a YZ250, so I then smoked him...lol sadly he passed away from an OD a few years ago. I just got a KX450F this year, didn't ride it as much as I wanted to, for sure next spring though.
Thank goodness you explored this option. I had the same exact thing happen to a 1996 model cr80 that I owned. Seems to be a common problem.
Yeah I think so. The seal really isn't held in by much...
I watch you videos regularly man! Big fan
It was had to tell from the video but the crank seal is only supposed to tap in until it's flush with the edge of the case. If you tap it in all the way it will burn that bearing up from lack of lubrication
I caught that too......I go a mil or 2 under flush......looks like he hammered it right up against bearing
Awesome fix. Powerful little bike.
I just wanted to let you know I found your channel a couple weeks ago and really enjoyed it I have been binge watching it like crazy and I also watch all commercials, do not fast forward through none of them but I have tell you about this one I’m watching a video from about 3 years ago and they just gave me a 46 minute commercial and yes I watched it so I sure hope you are going to make some extra money with my help lol
You the goatttttt who tought you about atvs i want to learn as well.. your videos teach me alot to
Love the videos keep up the good work your videos are so fun to see
new subscriber man. I love your content. I miss being on my old 98 cr250. I want to get my kids on the dirt and im poor so this on the cheap stuff is cool to see.
I had the same problem with the center clutch bolt some idiot tightened too tight. I had a buddy weld a bolt to it and back it out. Good video man.
Great video dude. I subscribed. Get that Yammy 200 runnin'...yeah!
Love the intro keep up this amazing work you’ve helped me learn so much I just rebuilt my 1992 Kawasaki kx80 big wheel.
It’s cool you’re putting the time in on the bike otherwise it would have been rusting away yet.
I would try jet change.play with air screw an jet needle.richen the needle going down one notch on needle.then go to air screw.for sure change the main jet .125 is pretty small.maybe 130 or 135???. Nice project.love the little 2 strokes!
Thing rips ..I'm actually looking for a bike about that size for my grandson ...but very well done fixing it and sounds good
Amazing how that crank seal affects it so much . That pulled up the wheels nice doggy!
Same thing happened on my bike lol good job finding the problem, keep up the good content
Rob metcalf was the first to guess that it was the crank seals in the first video. Nice bike! Cool video content and thanks for sharing!
We get that same addiction feeling you get your videos are awesome got to watch the whole video 👏!
Your videos are awesome I've learned so much...tks keep em coming man
good job man love your content !
You stirred my blood, I have to get a 2 stroke again,thanks for posting !
Early this time 👍 great vid do a day riding with friends or something like that
Awesome trouble shooting bro ! Spot on!
Nice videos mate. I like pulling the old bikes apart and getting them running again also.
Love you videos man
There's a tool for holding that clutch to take bolt out. Seems to work well. It bolts into the small bolt holes. On😊e more needed tool you should add bud!!
Probably should put the float position back where it was
Haha you're absolutely right
I haven’t even seen the series yet and found this in my recommended. As soon as the video started and he showed the oil in the exhaust I thought “Bad crank seals” and man is replacing them a sob. Did them on my KX80 and oh my god it took 3 pairs of them until I got it because one pair was too big and wouldn’t seal and the other pairs kept rolling over themselves when I tried pressing the crank in.
Gotta say i like that RM85 you had..was an 06 or 07 I think.. somewhere around this timeframe. Keep up the good work Joe! Try to find more RMs. How much to do an "expert" top end job on my RM85?
Love the sound if those small bore 2 strikes, cr 80 top o list!!
Good job finding the problem now get that carb and boot fixed 👍
Awesome video man
I don’t think there’s a bike you can’t fix I’ve been watching you for a while and your great at anything with a motor even electric hands down
I wish I lived close to you. I would purchase one of your bikes for sure. I had many dirt bikes. I started with a Honda XR-75. I purchased it from a friend of mine. He used it for dirt bike racing. Once he upgraded bikes, he sold me his. And it had plenty of power. I really enjoyed riding it. As i grew up, I upgraded models. Now I have none. Had to sell all to pay for medical bills after Cancer surgery. Now I have no money to buy one. I would Love to have another one. Like a 125 model.
Another killer video bro.. part 4 top speed test . .?
The video you made when you bought the bike i said crank seal but i thought at first it was the stator side. I even said how it would burn oil if it was the clutch side!! I had an 1985 cr 250 like yours that needed the crank seal on the clutch side but it ran good still but was burning the oil out of the trans!!
those were great little bikes ..i've often said if the 125 or 250 worked as good as the 80, cc to hp they would be so strong that they would be un drive able ...i'm not sure but it could be bogging and stalling due to air jet ..my 250 had chock that would turn in and out ...and that was how you set the idle air ..80's i don't remember i've had a few but none of them idled as soon as they started they were wide open till we put them away ..
Hm, Pumpkins!!! LOL - Nice work, glad you got er' running. You da man, stay safe and have fun!
My cr 80 did this to my crank shaft seal popped out and I bought a new one and it runs great.
🔥🔥I luv them 85s🔥🔥
Love your videos just found them ty
why does this guy haven’t reached 300 k. u know what to do boys
You often get a chemical reaction between metal and aluminum (oxidation). Sometimes soaking in Iodine releases this oxidation.
Sometimes when those brake pedal bolts come out hard is because there's a small cotter pin on the back side you can barely see but alot of people just crank them out and don't even realize it.
Oh yea new video loving it
You can fix that dent in the pipe pretty easy by making you a rubber plug for each end and naturally an air Chuck on one end put about 25 psi in it and heat that area of the dent with a torch and it will push it right out thats how Paul Turner racing used to do mine
You’re supposed to do seals flush with the case not bottomed out
Was just going to mention that......good catch
Looked like it didn’t matter
Made that exactly same mistake myself and the seal wore out quite quickly because bearing was rubbing into it. Had to change the bearing also because some rubber had entered into the bearing making it roll badly. Learned my lesson for sure :D Another thing in that video is that im quite sure 8.8 bolt is too soft for engine use, atleast in the powertrain. 10.9 or 12.9 is more likely be used because they dont stretch so easily.
Knowledge is Power
Watching you tear apart an engine is some how soothing like watching Bob Ross paint.
After this one I recommend you get that High Torque Milwaukee impact. Will save you when other impacts can't.
Yeah I might have to
Had the same issue with stuck bolts, i was using an 18v snap on impact, borrowed a 24v milwaulkee and the bolts come right out
I have one bought it on ebay used worth every penny. It will crack those bolts loose. Milwaukee battery powered will get the job done.
Or be a man an get a breaker bar. Yall weak af
@@corey123adams No way to hold it from spining is the issue here bud
Theres a tool to hold clutch for nut removal. Glad i got a couple. Not worth damaging the housing or gears.
You probably could if gotten it off with a air powered half inch impact or a decent breaker bar
In the future, use a bit of red loc tite when u put in the seal and that won’t happen again. Just around the outer rim, then push it in
I love my lil 87 kx 80 i have its prolly one of the most best running bikes ive ever had
Good deal and a somewhat easy fix.When trying to match a bolt,take the old one and find a nut that will go on it then you know the pitch and size
I’m thinking it wouldn’t hurt to replace the reed petals as well. I’m betting there as stiff as that old seal.
cracked intake boot can be repaired with shoe goo.. works like a charm!
The clutch nut/bolt is always pretty tight. I use a pneumatic impact wrench and it does the job. A small battery powered impact doesn't quite have enough torque.
To the 1%reading this: stay safe, and have a wonderful day! ( My Dream is to become a popular moto vlogger) Thanks! ✌
Put a socket over the shaft 2 seat the seal
Those 80’s were so run to ride back. In the days had so much balls
Yoo 2vintage I knew exactly what the problem was same thing happened to me it was popped out like that
I have the same marks on my 80 cr clutch don’t worry about it
Running lean from the filter on the fuel line.
A fuel filter cannot cause an engine to run lean . What it could do, is cause fuel starvation if filter is too small or becomes blocked .👍
@@jritchiejritchie2687 it filters the 2 stroke oil out of the gas........never use a fuel filter
Clutch basket wasted
Joe: I've seen worse, SEND IT!!!!!!
Awesome 👏 I wish you could work on my stuff!
Good bike man!
The same seal did that on my 2001 cr80 . I replaced them all . With the tusk kit .
That seal should be flush with the engine case and not pushed till it bottoms out because it will be blocking the passage for the fuel mixture to go though there will be 2 either side leading to the outside of the crank bearings so you will probably find that bearing will eventually give out
This is the stuff that makes me laugh that he does 🤦🏻, but getting better at some things.
THANK YOU SIR , MY ONLY QUESTION HAS BEEN ANSWERED BY YOUR COMMENT .
Why not put an OEM BOLT back in that clutch basket. And did you replace that case gasket or piece it back together.
Wasssssssuupppp 2vintage
Watching from Perth Western Australia 🇭🇲👍
U got my package
@@pyrexiabeats2313 what I don't get you
@@RagdollRacingInc just a joke since I ordered something from eBay and its now waiting in Perth Australia
Cool where you from mate
He helped me with the problem on my kx80 I took the pipe off and it started pouring oil so I went and bought the bearing kit for down there and now my bike starts up 1st or 2nd kick every time
Nice video bro this thing will rip
i love your videos
Clutch plates are toast
It is a lot more effective to use spray to find a air leak. Brake clean starting fluid carb cleaner all work.
The bike in my profile picture a bicycle with a 2 stroke 100 cc it has a 51 mm piston witch is a true 100 cc but it had a bad crank seal too I got it for only 100 bucks and now I got it fixed and boy she’s a beast
Next time your working on a clutch like that just put the bolts with the springs on back in without the plate with the bearing and put it in first and then put the hammer in the tire. That’s how you save the bolt and save your clutch from getting shavings in it. Just a little tip.
ThankYou I have a1995rt 180 and there like TH-cam video anywhere and you just save because it have the same problem as the cr 80
Those center clutch nut don't have a big torque spec, at least on the Yamahas I've worked on. BUT I could be wrong on this model. I just mean to say you shouldn't have had to fight it off the last guy overtightened
Pack that exhaust and thing will pull even harder. And that air leak fix should really wake that thing up
I had the same problem with my '97 R80, but for whatever reason, it doesn't want to run most of the time now. I've cleaned and adjusted the carb several times and messed with the air screw. And when it does decide to run, the throttle only responds with bogging. Even with that seal out of place before, the throttle responded properly.
UPDATE: Replaced the crank shaft seal and borrowed a carb from another CR80, it runs great, except the rear shock is clapped.
Could need a engine rebuild or more likely theres a fuel issue
@@theonewhoknows2 I updated my comment just now.
You the man good for you.
Turn the air screw in a little bit and see how it runs
I've never seen that happen to a crank seal, easy fix i guess!
the older cr’s look killer
I need to do my crank seal on my 03 cr85 who ever did last rebuild dint take time to do it all the right way lol used a cylinder with a chunk missin out the sleeve and seal in wonky home made dowl pins out of can of coke but ive almost done it all now just seal left to do today if weathers ok
