As soon as it started you could hear the cam chain rattling like crazy. Sounded almost like it had no tensioner. Guess we’ll find out. Another good learning experience.
same thing has just happend to my 2017 kxf 450, cam tensioner failed threw cam chain off, locks up as the piston is hitting valves, new tensioner and cam chain just to be safe, and shes running like a beauty again thank god, i was on a track aswell i shit my pants haha
I couldn't tell if that's what I heard or detonation, it's hard to hear, especially while it's idling to the moon on a brand new engine, then giving it throttle ontop of that. Every video "it sounds good" meanwhile you hear that, or a 2 stroke that's sputtering or detonating, especially when he's riding them and has load on the engine.. He's a good mechanic for sure, good at diagnosing issues, but he doesn't know how to tune a bike, what he's listening for, or what a properly tuned bike sounds like....and he revs the piss out of everything for absolutely no reason at all.
At the end when you started it in the field i literally went like "damn that rebuilt engine might have a slight noise to it" Sounds like its definitely gonna be rebuilt now lol.
You're a genius buying all these minor broke down bikes and fixing them for your channel most of the time people give up on something because they don't know enough to work on them so they sit and or get sold you're very smart to do what you do ...I really enjoy watching your vids
This exact bike I see all over marketplace for 3k+ “just rebuilt, she rips, she just won’t start today” 😂 I can’t wait to see when the head is pulled, love the content 🙌
Must be a lot of people with my skill level. Give me a decent running engine, a spark plug, and tools. Two hours and a sweat soaked floor later, that bike will be scrap metal😂
What a huge bummer. Joe, I have learned many things in my life, but one lesson I have learned in my 65 years, is never to assume anything! I would have torn down the top end on that bad boy, just because someone else said they rebuilt it, doesn't mean they did it right or have your level of competence in rebuilding engines. I have seen some of the stupidest shit in a ledgy rebuilt engine. Things only being halfway installed or put in upside down or backward. Seals not seated Etc. Can't wait to see what the FUBAR is with this one! :) PS: I am thinking the chain guide was not installed right or locked in and the chain came off letting the valves hit the top of the piston, plus when you are in there look at that spark plug-hole threads, I think they may be buggered up and may need a thread chasing. Just a thought.
If someone doesn't have the competence to clean the carbs, he certainly doesn't know how to rebuild an engine. That would be a red flag, but to Joes credit, he checked the timing, the valve clearance was perfect and the timing chain looked very good too,...soooo. I would have probably done the same and blew the engine.
Definitely could here the rattle when started at the garage, but when started at the land it sounded completely horrible it was like a ticking time bomb
Don't think for a second that Joe didn't purposely ride it after hearing it. He's a content creator who's repaired hundreds of engines. He knows what he's doing.
Exactly .... 50k+ views so far ... then it locks up which is another 50k view video ... plus all the hater comments ... its called a business model ...
He did the same stupid shit when his channel just started. It took him a year to not rev cold engines to the moon etc. I think he is somewhat deaf ( He doesn't hear a slipping clutch/engine that mis-fires/engine rattling in frame/valve knocking/jetting slightly of etc). and maybe compulsive disorder (OCD). Watch him closely he never takes a step back and think for 2 seconds.
I have to believe this as well. He just suddenly forgot how to hear a tick, after investigating the same noise countless times before? He creates content. I'm not mad.
I was thinking when you fist started the bike up in the field for the test drive, those valves were noisy as hell . There was a lot of ticking. I guarantee it was something to do with the valves and calm chain. We’ll see you in the next video.
Absolutely! I've been trying to tell him this also. Plus, you don't have to twist and contort the intake boots risking tearing them. Trying to wrestle the carb out instead of removing the subframe is a sign of a hack in my book.
@@stkyfngrszmooth I raced ama motocross for 20 years,I was my own mechanic. Some of the first bikes I owned didn’t even have a removable subframe.

I wouldn’t call him a hack just a little bit green yet,he’s still young and will have plenty of time to learn from his mistakes.

He grabbed it and set it up in the Bridgeport and proceeded to shave the grooves out, and he got to the very last set of grooves and accidentally bumped the handle and snapped the tang(?) right off. Then he stuck me with the $80 replacement bill.

I watched him one time start a bike on fire , he learned from that mistake for sure but I commend him for posting it and not just simply editing out that rookie mistake ,as he could’ve easily have done too in this video. Never rely on someone trying to sell you his bike that his rebuild was done right,especially if you didn’t get to hear it run before you buying it.
Well that sounded like a timing chain the second it fired up in my opinion and surprised you couldn’t hear it bro but sorry that it locked up hope it’s an easy fix, look forward to the next video keep up the good content 👍🏼
I would bet money it’s the Cam chain. I’ve heard stories about those things dropping chains!! Personally I steer clear of anything 4 stroke if you don’t know the history of the the competency of the rebuilder! Obviously the guy wasn’t too freaking bright if he missed a pilot jet, and I plugged breather or fuel line! That’s the first stuff to check! The simple stuff! Great video!
Most TH-camrs wouldn't of shown that at the end of rebuild don't worry you will rebuild it better than before hopefully 😊 gonna be a great build for sure keep your chin up brother 🖤
@benmitcham62 yeah i wish my yamaha would gave me a sign like tick or hard to start it just ran like bat out hell until it went boom and one valve ruined my whole motor
I'm always nervous when the previous owner rebuilt it. Bought a cbr250r cheap, non running, that the PO rebuilt. I found clutch springs missing, bolts not torqued down. Glad it never started or it would have blown up for sure. I got it all sorted and it was a great bike.
When will he stop believing the seller. How many bikes and quads has he been told are fresh rebuilds and turned out to be hammered shit. He's to trusting. To much metal in the oil to be a fresh rebuild. It had a glitter cloud in it and some pieces. It wasn't knocking tho. I was thinking crank /connecting rod bearing again.
@@waffalobill I was shocked when the spark plug was really tight, and then he couldnt get the compression tester to go in. At that point I would have stopped and taken the engine apart.
@@chriswedgwood9673I'm always leery about the ones that say just rebuilt it, can't get it to start. I would go over everything they did. I would never jump on a bike and not check the axle nuts, triple tree etc. stuff that will kill you if they left it loose. The guy probably half assed the rebuild or didn't even do one. Bet the bottom end hasn't been done either.
Personally, whenever a customer would tell me they did "this" or "that" to their bike and proceed to tell me they're a dentist by trade, I double-check everything they said they did. Plus, it's easy to spot the phonies just by asking them a few mechanical questions and listening to their answers. When they start making no sense, it's full tear-down time.
@@stkyfngrszmoothshould have took a couple driveway test laps before loading it up. The glitter cloud in the oil said there was issues. You could see metal flakes. He seen them. I would have checked them with a magnet. Anyone who drops the serious coin in a bike to rebuild the top and bottom end but not do the water pump seals? Coolant ran right thru it. He gave him the seal so he knew it was pooched. He actually tryed to start and run a fresh rebuild with no coolant? Think Joe got took again. Can usually see new gaskets. I can't see them. He didn't check the cases before buying it? He's got shafted like that before. But maybe he did look. That looks was for us. Not sure. It's hard to tell on the video. The sound isn't the same as standing there. It always sounds noisy. Can't tell by sound on our end. Real curious. But I think he got took again.
Joe, If he couldn't get it running after a rebuild, I would take it all apart and do it again right. He screwed something up. If he didn't know how to clean the carb, you can bet the rebuild is bad. In the end, it quit.
seller said it wouldnt start so what does he do . Takes it out of the truck and kicks it over 100 times. If it was that easy dont you think the seller couldve did that lol
Yeah the sound from 49:00 - 49:50 was not good. Probably very hard to hear outside with the loud exhaust. However through the audio picked up from the camera you could hear a mechanical clanking. Interesting to see what failed.
I was biting my tongue before you ever took it to the land and when you did, the way it is was running. No way, I would have packed it back up to tear the engine down. it's fixing to get a rebuild now and I'll enjoy watching you do it, hehe
And that is the story on every 4 stroke around my area. Best to stay clear of them unless you have an endless supply of money. They where junk new and still junk now.
I gotta hand it to you, Joe. You never seem to get angry. I'd be pissed if I put in that much work only to have a bike grenade in the first fifty feet. At least now, when you sell it, you can claim that virtually everything is brand new engine-wise.
@nikhayes3396 thats what i was talking about didn't see him check timing but i was doing other stuff while listening. Just ment it sounded like a timing chain hoping teeth
@@jamesclark4 gotcha. when it locked up? I don’t think he checked the tensioner assembly but he did check the timing chain tension obviously, as its right there when you have the head cover off. lets be honest though, someone tells you they rebuilt a bike and since it wont run, and you open up the carb and notice right away its not squirting fuel, clean it, and it starts, makes some odd sounds and locks up the engine 10 ft into your first ride, it could be anything.
I currently have this bike and it was cool to see it being worked on. tension on the chain was low, those tensioners on the side of the cylinder head can be a pain to deal with cause they are auto tensioning. I bet the last guys put it on wrong. The weird thing is the valve train is really loud on these bikes and it sounds like they're rattling apart at full throttle. Also, id recommend putting actual trans oil in it 80/85W, it works a bit better. Should be fun to watch a rebuild on the bike though!
When I watch Joe struggle to get the plug loose, it always reminds of a day at the motocross races when the guy next to me was using a cheater pipe on his ratchet to tighten his plug. He came so close to pulling all the threads out that when he cranked it and was driving to the gate, it blew the plug out. I never would have thought you could over do it that much. I laughed so hard.
Classic “I lost the receipts” build. Sounded like the cam chain went on a trip, whether the tensioner was ill adjusted or the cam sprocket wasn’t tightened correctly. Even if they did have it running, without a load you may not notice it. The good thing is if you roached the head there’s tons of good used parts available for them, they make good budget “thrash” bikes for woods racing when it’s muddy or need some practice.
Some people clean their parts before disassembling or during repair en before assembly.😅 Would love to see you do this too, you know, and take your work up a notch. I love your videos and you are great at fault-finding but with the execution of the repairs, with all the dirt and grime still on the parts you get the chance of sand or dirt falling in the bottom end or when installing a dirty cylinder head get dirt in the cylinder. Please don't be offended this is not my intention.❤
You guys need to relax… this isn’t a “perfect restoration” video its a “let me fix this enough to sell it so i can make my money back” video. The bike is damn near 20 years old, its not a brand new lambo.
@@grumpygamer1982 WTF are you talking about??? 10 min with a pressure washer before you begin working on it and a couple of minutes cleaning the parts in your hands with a degreaser before putting it all back together. That is not your so-called “perfect restoration” video. That is "do a clean job", You have the parts in your hands, so you may as well clean them, if not for specific to want clean parts do it for handling,it is a lot more pleasant to handle parts without oil and dirt stick on your fingers and hands. So no one is talking about restoration or PERFECTION it is just repairing. Cleaning parts is not a restoration.
I am new to watching your videos but I really enjoy them and I watch this one on the 250 and I couldn’t help but notice when you first got this thing charting that no smoke came out of the rear tailpipe it all the other ones they’re two stroke engines so so I mean you know you have to have the gas oil mix and they all puffs and smoke out all two strokes do it. It’s normal for a two stroke and that one puffed out no smoke. It ran clean like it was a four stroke I think that’s your problem that it didn’t have oil in there and that’s why the thingburned up or seized up within the first couple of minutes of driving it
Oh 2vintage working on a bike similar to mine (2009 carb crf250r), can't wait for the rebuild video. Keep up the good work Joe you are the oasis in the desert of youtube diy mechanics. Cheers from Greece europe!
Not sure if you know this Joe but on the older Hondas, engine oil and transmission fluid are separated in the engine unlike all the other bikes that share 1 oil through the whole motor.
Did you just blast the debris in the clogged line back into the carb? The violence taking the spark plug out is hard to watch too but I can see your skills are coming up, admire your honesty when it goes wrong at the end.
Hey bro awesome video, i am an owner of this bike, and there is a trick to make it start, give it 4-5 gentle kiks to gain compresion, and then kik it hard with the throttle open at like 5% if it doesnt start, repeat process
I am surprised you don't have a lift table... I used to ride bikes 40 years ago, I still love to watch your videos even though I will never ride again... except my electric bike....
Why aren't you using a small chair or the central stand of the bike to stand on it with your left leg when kicking the bike over? You will be sitting on a higher point and you will have a lot more leverage kicking it over, a lot more pedal travel with a higher impulse and you don't put so much tension on your right leg. What if it kicks back and your thigh is bent over to the back? if you are over the bike standing upright, you might have a chance saving that knee. Btw cool content you have and super patience. Awesome. keep up the great work. enjoying watching you.
Every Honda unicam I’ve ever owned has started like that. Not sure if you did it off camera, but don’t forget to re time the accelerator pump shot. You want it to just barely clear the slide when you blip it
I could hear Chain noise setting there Idling ..And when you took off it got real loud. The Chain noise.. Wonder if the chain was rubbing on something or Tensioner wasnt working right .
That's why when people tell me I just did a total rebuild, I questioned there skills , cus if I don't build it or it's done by a reputable shop I don't trust anyone
Even at the shop when you said "sounds good now" i was like no it doesnt. Thing sounded like it was going to blow up at the shop already. Then you could definitely hear it while out in the field. That cylinder is probably done. Bent rod, carnage, etc
I used to unload bikes like that until my boot got caught on way down and I fell and bike landed on me. I was off for a day or so then I bought a SxS. I also bought an aluminum trailer, ever since I have never put anything in the back of my truck. My aluminum trailer has a gate and it’s easy as heck to load lawn mowers, bikes, quads, SxS, everything. I should have got a trailer years ago. Even if I go to the dump or compost lot, it goes on the trailer.
What had me was soon as you were checking it over a New build low on oil of all things I think in the future if someone says it’s freshly rebuilt it’s worth just tearing it apart and start over you can’t guess what did or didn’t right
Will be good to see what it was. It happened to me when I refreshed my 93 CR125 (in 93). I used a Wiseco piston and did not mic it. It was oversized, so when the engine heated up under load it locked up. Frustrating, but that should always be checked, just like the ring gap. Absolutely not saying it was your fault, but it does happen that new parts get shipped out of spec. Same exact noise/ reaction by the way.
The bike sounded like a ticking time bomb with the valve knock... You checked what I thought might make those terrible sounds, but those sounds are never good and need investigated ASAP especially after a rebuild. This wasn't your fault and it is killing me wondering what gave way inside the motor Joe! Maybe some Chinesium parts were used by the previous owner in the rebuild? I love your videos and keep up the good work! You have came a long way over the years buddy!
A little helpful advice when you hear a motor rattling like that thing was shut it off. I can hear that thing rattling as soon as you started it up I know you could hear it lol you live you learn
I left the fuel petcock open over the winter and when I went to start my '04 CRF450R it wouldn't. It would start for a few seconds if I pulled the hot start (adds air) so I knew it was the carb. Cleaned and rebuilt the carb and no joy. Took it to the dealer and that was a shit-show. It was there for over eight months. I finally bought a new carb and that fixed it.
I've always been of the opinion, Joe, that if I'm going through and doing a bottom and top end complete rebuild, I'm changing the water pump seals, probably putting a new impeller in there anyway, but man to have done ALL that work and skipped a couple seals? Nah.. no way that's definitely a 'while you're in there' to do.
I love when you work on more of the modern bikes,ATV’S I like the classic ones too just not as much. But All the content is Awesome Love the channel keep the awesome content coming
When it first started off there was a weird sound I felt it was some plastic rattling but when it blew up I think it must be the timing chain tension was loose
You're paying your dues Joe. Someday you'll not be so trusting of the knuckle heads you buy these bikes from. I understand though, at the rate that you move bikes through, it's a gamble. At least you instantly have content for a future video!! If the previous owner couldn't figure out the carb, chances are the engine that he supposedly fully rebuilt is suspect. By the time you're in you're in your 50's, you'll know better than to trust anyone but yourself. Thanks for all the content you put out. It's very entertaining and often has me reeling with emotion!! 😂
the money he makes form your tube is great,he pays nothing in the end for these bikes,so dont feel to bad for him.do you see his house he bought for you tube vids?
If you take 1000 people that state "I just rebuilt it" 999 of them had no idea what they were doing... Signed, a 30 year bike tech. I was worried when you started it but was hoping it was the radiator or exhaust shield loose or something like that rattling. You just can't trust the general public when they say the overhauled anything...
When you check the cam chain it was fine but the tensioners are known to be fine when you check them by hand but under force they decompress when they fail causing loose chain causing catastrophic events. A manual cam chain tensioner will cure this the oem ones are known to fail shoot i think it happened in 02 on crf450r during championship
On those 05-09 crf250-450s you’ve gotta find tdc everytime and the decomposition mechanism blows the spark out on start up you’ve gotta adjust it. Upallnight on yt has a video on it. I just had a 2005 with that same issue. You don’t need the hot start either mine was deleted
I am for sure he can tell that the engine wasn't running right , he just went ahead and made the video anyway, he don't care about the engine blowing up, he'll rebuild it, I enjoy watching the videos , And I'm sure everyone else does also,
That's the valves gone. Timing chain rattling before you send it in the field. Strange you did not notice. Cross fingers for the new top-end... i would have checked the quality of the rebuild. If he used crap, you would be f****d anyway. Can't wait for the next video uploaded😊
Love your videos Joe, curious as to why sometimes you don't kick the bike over or check fluids at the owners home ? Keep the videos coming ! I do learn from you ! Thanks john

I'm always nervous when the previous owner rebuilt it. Bought a cbr250r cheap, non running, that the PO rebuilt. I found clutch springs missing, bolts not torqued down. Glad it never started or it would have blown up for sure. I got it all sorted and it was a great bike.
When you first started it up, you could hear timing chain slapping around. This would also be the reason for hard starting and needing to pump fuel.
your patience is second none with these bikes and people you acquire these machines from, you're a rare breed this day and age I salute you !!!
Note to Future self:... when seller claims to have rebuilt the top end, Buyers protocol: double check timing chain tension!
When will he stop believing the seller. How many bikes and quads has he been told are fresh rebuilds and turned out to be hammered shit. He's to trusting. To much metal in the oil to be a fresh rebuild. It had a glitter cloud in it and some pieces. It wasn't knocking tho. I was thinking crank /connecting rod bearing again.
@@waffalobill I was shocked when the spark plug was really tight, and then he couldnt get the compression tester to go in. At that point I would have stopped and taken the engine apart.
@@chriswedgwood9673I'm always leery about the ones that say just rebuilt it, can't get it to start. I would go over everything they did. I would never jump on a bike and not check the axle nuts, triple tree etc. stuff that will kill you if they left it loose. The guy probably half assed the rebuild or didn't even do one. Bet the bottom end hasn't been done either.
Personally, whenever a customer would tell me they did "this" or "that" to their bike and proceed to tell me they're a dentist by trade, I double-check everything they said they did. Plus, it's easy to spot the phonies just by asking them a few mechanical questions and listening to their answers. When they start making no sense, it's full tear-down time.
@@stkyfngrszmoothshould have took a couple driveway test laps before loading it up. The glitter cloud in the oil said there was issues. You could see metal flakes. He seen them. I would have checked them with a magnet. Anyone who drops the serious coin in a bike to rebuild the top and bottom end but not do the water pump seals? Coolant ran right thru it. He gave him the seal so he knew it was pooched. He actually tryed to start and run a fresh rebuild with no coolant? Think Joe got took again. Can usually see new gaskets. I can't see them. He didn't check the cases before buying it? He's got shafted like that before. But maybe he did look. That looks was for us. Not sure. It's hard to tell on the video. The sound isn't the same as standing there. It always sounds noisy. Can't tell by sound on our end. Real curious. But I think he got took again.
When it was running on the land, it sounded like a bag of nuts and bolts. I was surprised you decided to take it out.
You could hear the chain while it was running. Probably loose and skipped when you rode it.
yep thats exactly what i was thinking
Didn't you hear it rattling like hell when it was idling on the stand?
hes tone deaf
He heard it, "hmm...sounds like a bunch more videos for the algorithm" 😂
Joe, If he couldn't get it running after a rebuild, I would take it all apart and do it again right. He screwed something up. If he didn't know how to clean the carb, you can bet the rebuild is bad. In the end, it quit.
yea the rebuild lol
sounded like a diesel KLR
seller said it wouldnt start so what does he do . Takes it out of the truck and kicks it over 100 times. If it was that easy dont you think the seller couldve did that lol
Sorry about your luck but at least we'll have a good teardown to watch!
You could tell from the sound that something was wrong when you started it.
Yeah the sound from 49:00 - 49:50 was not good. Probably very hard to hear outside with the loud exhaust. However through the audio picked up from the camera you could hear a mechanical clanking. Interesting to see what failed.
It sounds like worn piston rings or some other part of the engine vibrates and makes similar sound as worn rings.
First thing I thought when you explained it had been rebuilt but wouldn't run was I would want to check ring gaps, piston and bore size etc.
It always amazes me how they dont just replace everything on the carb
Wow... bummer... Looking forward to seeing what the problem is... Great videos... Thank you...
Dude you can hear the timing chain slapping around everywhere when it was idling and when you took off. You should know better my goodness 😃
lmfao im glad other people notice this shit
Truth😂
The smiling face at the end? Are you stupid or something?
You mean rattling on the guides? If the cam was “all over the place” the bike wouldn’t idle or take off… you’re stupid
It’s ok though. He was the only one that could fix this bike. Remember, nobody could fix it.
Why would you run it with it sounding like it was going to grenade any second 😂
Ya heard that mad tick while he was still in the garage🤦♂️ cringed when he went to ride it😅 we all make mistakes I guess.🤷♂️ love the content!
If I'm the "Hired Shoe" - WHY NOT? It's not MY motor.
how many times you buy a bike and was told it has a new rebuild LOL
I'd rather buy a basket case than a just rebuilt but won't start bike. Most these guys can't fix a weed wacker.
I was biting my tongue before you ever took it to the land and when you did, the way it is was running. No way, I would have packed it back up to tear the engine down. it's fixing to get a rebuild now and I'll enjoy watching you do it, hehe
When you started it at the land, it didn't sound too good..I wasn't sure if it was sound on phone..guess not....
And that is the story on every 4 stroke around my area. Best to stay clear of them unless you have an endless supply of money. They where junk new and still junk now.
I gotta hand it to you, Joe. You never seem to get angry. I'd be pissed if I put in that much work only to have a bike grenade in the first fifty feet. At least now, when you sell it, you can claim that virtually everything is brand new engine-wise.
I guess if the same guy that couldn’t fix a basic carb issue rebuilt it…. I guess… i can’t wait to see what you find.
Probably timing was off or timing chain was lose because it sounded like the timing chain issue
@@jamesclark4 Well: the only problem with that is he checked the timing and the timing chain tension etc. etc.
@@jamesclark4 you maybe hadn’t watched the whole video when responding. the engine locks up at the end too.
@nikhayes3396 thats what i was talking about didn't see him check timing but i was doing other stuff while listening. Just ment it sounded like a timing chain hoping teeth
@@jamesclark4 gotcha. when it locked up? I don’t think he checked the tensioner assembly but he did check the timing chain tension obviously, as its right there when you have the head cover off. lets be honest though, someone tells you they rebuilt a bike and since it wont run, and you open up the carb and notice right away its not squirting fuel, clean it, and it starts, makes some odd sounds and locks up the engine 10 ft into your first ride, it could be anything.
You need to interview these sellers when you purchase these. It would tell so much more of the story😂😂
All the sellers are like the first episode of house M.D, "everybody lies"
I changed my viewing expectation to comedy, works much better for me. 👍
It’s all comedy on this channel, joes a fool. It’s rebuilt cause the previous owners said it is ,lol
What’s the boot for , you are such a baby boy
Your brain is loose
You can absolutely block it off not necessary
Water pump seal is shot
It looks like you need a hug from mom that always helps
😊 you could here that timing chain saw doing it's work, long before it locked FFS!
I currently have this bike and it was cool to see it being worked on. tension on the chain was low, those tensioners on the side of the cylinder head can be a pain to deal with cause they are auto tensioning. I bet the last guys put it on wrong. The weird thing is the valve train is really loud on these bikes and it sounds like they're rattling apart at full throttle. Also, id recommend putting actual trans oil in it 80/85W, it works a bit better. Should be fun to watch a rebuild on the bike though!
Wait, wait…when you first started it I was yelling at my screen saying, “it will blow up in 2 seconds”😉
Wrap teflon
tape around your compression tester, it may help some what tighten in the threads.
When I watch Joe struggle to get the plug loose, it always reminds of a day at the motocross races when the guy next to me was using a cheater pipe on his ratchet to tighten his plug. He came so close to pulling all the threads out that when he cranked it and was driving to the gate, it blew the plug out. I never would have thought you could over do it that much. I laughed so hard.
Need a T-shirt with hmmmm on it under a torn apart bike or ATV. Lol love your videos please keep them coming!!!
Bummer🙁 Man, I was really rooting for you. Looking forward to what the heck happened. Vinny didn’t do his inspection 😁
Classic “I lost the receipts” build. Sounded like the cam chain went on a trip, whether the tensioner was ill adjusted or the cam sprocket wasn’t tightened correctly. Even if they did have it running, without a load you may not notice it. The good thing is if you roached the head there’s tons of good used parts available for them, they make good budget “thrash” bikes for woods racing when it’s muddy or need some practice.
Ha! 😆😂 I thought it sounded like a bucket of bolts rattling when you were kicking it over!! 😮😅
Should have checked the oil filter for bottom end metal. The ticking sound was your warning. Anyway, like your content. Keep em coming.
Some people clean their parts before disassembling or during repair en before assembly.😅
Would love to see you do this too, you know, and take your work up a notch.
I love your videos and you are great at fault-finding but with the execution of the repairs, with all the dirt and grime still on the parts you get the chance of sand or dirt falling in the bottom end or when installing a dirty cylinder head get dirt in the cylinder.
Please don't be offended this is not my intention.❤
You guys need to relax… this isn’t a “perfect restoration” video its a “let me fix this enough to sell it so i can make my money back” video. The bike is damn near 20 years old, its not a brand new lambo.
@@grumpygamer1982 WTF are you talking about???
10 min with a pressure washer before you begin working on it and a couple of minutes cleaning the parts in your hands with a degreaser before putting it all back together.
That is not your so-called “perfect restoration” video. That is "do a clean job",
You have the parts in your hands, so you may as well clean them,
if not for specific to want clean parts do it for handling,it is a lot more pleasant to handle parts without oil and dirt stick on your fingers and hands.
So no one is talking about restoration or PERFECTION it is just repairing.
Cleaning parts is not a restoration.
@@jacksat2252quit your bitching go clean your parts then
@@jacksat2252 i agree, also more enjoyable to watch
I am new to watching your videos but I really enjoy them and I watch this one on the 250 and I couldn’t help but notice when you first got this thing charting that no smoke came out of the rear tailpipe it all the other ones they’re two stroke engines so so I mean you know you have to have the gas oil mix and they all puffs and smoke out all two strokes do it. It’s normal for a two stroke and that one puffed out no smoke. It ran clean like it was a four stroke I think that’s your problem that it didn’t have oil in there and that’s why the thingburned up or seized up within the first couple of minutes of driving it
Oh 2vintage working on a bike similar to mine (2009 carb crf250r), can't wait for the rebuild video. Keep up the good work Joe you are the oasis in the desert of youtube diy mechanics. Cheers from Greece europe!
Not sure if you know this Joe but on the older Hondas, engine oil and transmission fluid are separated in the engine unlike all the other bikes that share 1 oil through the whole motor.
Did you just blast the debris in the clogged line back into the carb? The violence taking the spark plug out is hard to watch too but I can see your skills are coming up, admire your honesty when it goes wrong at the end.
Hey bro awesome video, i am an owner of this bike, and there is a trick to make it start, give it 4-5 gentle kiks to gain compresion, and then kik it hard with the throttle open at like 5% if it doesnt start, repeat process
I am surprised you don't have a lift table... I used to ride bikes 40 years ago, I still love to watch your videos even though I will never ride again... except my electric bike....
Why aren't you using a small chair or the central stand of the bike to stand on it with your left leg when kicking the bike over? You will be sitting on a higher point and you will have a lot more leverage kicking it over, a lot more pedal travel with a higher impulse and you don't put so much tension on your right leg. What if it kicks back and your thigh is bent over to the back? if you are over the bike standing upright, you might have a chance saving that knee. Btw cool content you have and super patience. Awesome. keep up the great work. enjoying watching you.
Every Honda unicam I’ve ever owned has started like that. Not sure if you did it off camera, but don’t forget to re time the accelerator pump shot. You want it to just barely clear the slide when you blip it
It really started making noise before you left for the ride. Hope it's not too bad. I can't wait to see.
I could hear Chain noise setting there Idling ..And when you took off it got real loud. The Chain noise.. Wonder if the chain was rubbing on something or Tensioner wasnt working right .
That's why when people tell me I just did a total rebuild, I questioned there skills , cus if I don't build it or it's done by a reputable shop I don't trust anyone
Even at the shop when you said "sounds good now" i was like no it doesnt. Thing sounded like it was going to blow up at the shop already. Then you could definitely hear it while out in the field. That cylinder is probably done. Bent rod, carnage, etc
fun tip you can use the coil to grab the spark plug once you have it loose
Just one time, for science…….touch the spark plug tester 🤣
I think I heard your cam chain clinking before you took off.
I used to unload bikes like that until my boot got caught on way down and I fell and bike landed on me. I was off for a day or so then I bought a SxS. I also bought an aluminum trailer, ever since I have never put anything in the back of my truck. My aluminum trailer has a gate and it’s easy as heck to load lawn mowers, bikes, quads, SxS, everything. I should have got a trailer years ago. Even if I go to the dump or compost lot, it goes on the trailer.
What had me was soon as you were checking it over a New build low on oil of all things
I think in the future if someone says it’s freshly rebuilt it’s worth just tearing it apart and start over you can’t guess what did or didn’t right
I can check the valves, timing, cam chain pretty fast on my 2-stroke!
Me 1 minute after the bike started:
"Hold up, wait a minute... something ain't right"
Lol
Will be good to see what it was. It happened to me when I refreshed my 93 CR125 (in 93). I used a Wiseco piston and did not mic it. It was oversized, so when the engine heated up under load it locked up. Frustrating, but that should always be checked, just like the ring gap. Absolutely not saying it was your fault, but it does happen that new parts get shipped out of spec. Same exact noise/ reaction by the way.
Joe is ready for summer, the shorts and t-shirt have come out
The bike sounded like a ticking time bomb with the valve knock... You checked what I thought might make those terrible sounds, but those sounds are never good and need investigated ASAP especially after a rebuild. This wasn't your fault and it is killing me wondering what gave way inside the motor Joe! Maybe some Chinesium parts were used by the previous owner in the rebuild? I love your videos and keep up the good work! You have came a long way over the years buddy!
Joe uses chinesium parts all the time?
Love that u fix all the bikes that guys dont have a clue whats wrong u f.....king rock bro been a sub for three years
A little helpful advice when you hear a motor rattling like that thing was shut it off. I can hear that thing rattling as soon as you started it up I know you could hear it lol you live you learn
Wasn’t expecting the bike to lock up at the end. 😅. Looking forward to the next video for this bike. Cheers joe
The FIRST start i heard a strange noise and was waiting for that... yikes. KNEW it.
I left the fuel petcock open over the winter and when I went to start my '04 CRF450R it wouldn't. It would start for a few seconds if I pulled the hot start (adds air) so I knew it was the carb. Cleaned and rebuilt the carb and no joy. Took it to the dealer and that was a shit-show. It was there for over eight months. I finally bought a new carb and that fixed it.
Bummer on the misfortunate situation, but I'm eager to see what you find out. Every setback is a learning opportunity.
Everyone should have this guys cool tempered nature.. cool heads ..
I've always been of the opinion, Joe, that if I'm going through and doing a bottom and top end complete rebuild, I'm changing the water pump seals, probably putting a new impeller in there anyway, but man to have done ALL that work and skipped a couple seals? Nah.. no way that's definitely a 'while you're in there' to do.
Nobody could fix it 😂🤣😂😂
Only 1 person tried to after being rebuilt then old joey boy blows her up 😂🤣😂🤣😂
lol,so true,his channel is becoming a joke!!!
I love when you work on more of the modern bikes,ATV’S I like the classic ones too just not as much. But All the content is Awesome Love the channel keep the awesome content coming
sounded like the piston hit the valves. Curious to see what you find out.
When it first started off there was a weird sound I felt it was some plastic rattling but when it blew up I think it must be the timing chain tension was loose
You're paying your dues Joe. Someday you'll not be so trusting of the knuckle heads you buy these bikes from. I understand though, at the rate that you move bikes through, it's a gamble. At least you instantly have content for a future video!! If the previous owner couldn't figure out the carb, chances are the engine that he supposedly fully rebuilt is suspect. By the time you're in you're in your 50's, you'll know better than to trust anyone but yourself.
Thanks for all the content you put out. It's very entertaining and often has me reeling with emotion!! 😂
He is truly an eternal optimist thus far in his life. Time will test him.
the money he makes form your tube is great,he pays nothing in the end for these bikes,so dont feel to bad for him.do you see his house he bought for you tube vids?
If you take 1000 people that state "I just rebuilt it" 999 of them had no idea what they were doing... Signed, a 30 year bike tech. I was worried when you started it but was hoping it was the radiator or exhaust shield loose or something like that rattling. You just can't trust the general public when they say the overhauled anything...
41:50 radiator is loose. Sounded like a rattle somewhere when you first fired it up. Great diagnostic skills bud!
When you check the cam chain it was fine but the tensioners are known to be fine when you check them by hand but under force they decompress when they fail causing loose chain causing catastrophic events. A manual cam chain tensioner will cure this the oem ones are known to fail shoot i think it happened in 02 on crf450r during championship
Anxious to see what is wrong and where the problem is. I’m betting whoever did the last rebuild made a mistake.
Oh no!!! I was rooting for you, then kabooie! I know you will get her fixed. Can’t wait to see what it is.
Fresh rebuild and the water pump seal was leaking...😮❤
On those 05-09 crf250-450s you’ve gotta find tdc everytime and the decomposition mechanism blows the spark out on start up you’ve gotta adjust it. Upallnight on yt has a video on it. I just had a 2005 with that same issue. You don’t need the hot start either mine was deleted
I am for sure he can tell that the engine wasn't running right , he just went ahead and made the video anyway, he don't care about the engine blowing up, he'll rebuild it, I enjoy watching the videos , And I'm sure everyone else does also,
That's the valves gone. Timing chain rattling before you send it in the field. Strange you did not notice. Cross fingers for the new top-end... i would have checked the quality of the rebuild. If he used crap, you would be f****d anyway. Can't wait for the next video uploaded😊
Love your videos Joe, curious as to why sometimes you don't kick the bike over or check fluids at the owners home ? Keep the videos coming ! I do learn from you ! Thanks john
Joe bout got lit up with that spark tester!
