I admire your patience and logical thinking diagnosing the issues. I used to strip and rebuild UK Mini's in my late teens in the 70's. Never had much money and needed to continually repair to keep on the road to get to and from work.
For $700 its a no lose project ... get like 4 vids out of it, spend a few hundred and sell it for 3 er 4k once the smokin is fixed. Also great op to show people many small probs to look for, aka wrong washers ... takin time to look at schematics of engine systems is golden lesson ...
Always the shafts. Do a lot of those repairs here on those quads, keep them in shop stock with seals, etc. Great job and vid. Impressed with how you've come so far so fast as a mechanic. Dig into everything just builds your overall knowledge, great job!!
Looks like you are crop dusting....lol. You are a master of fixing other people's inept repairs. Some people should NEVER EVER work on mechanicals. Great job!
I have an 02 and watching this was very helpful just to watch if I come into these problems. I thought it was the timing from the begining but you showed it was much more then that! Thanks!
Joe -- This Old Guy Loves All your videos. I have a 77 RM Suzuki to replace the piston which lost one of the tiny pins that holds the rings from turning. Back together engine would start & run gets warm then quits. Never saw that happen before, took me a while to figure out. LOL Here's a tip for All your Readers.... Plastic Oil bottles are designed with the spout at the far end to be poured with the spout Upside not down. This Prevents the Glug Glugging after starting to pour with the majority of the oil at the bottom half of the bottle & allows air to get into the bottle more quickly to prevent a mess. In some cases if the cap hole dia. is large enough like in autos you don't even need a funnel. Prevents a Big Mess. Try It -- You might like It
Good job, great video. I would have avoided someone else's "modifications" but props to you, and Vinny. Seeing your joy riding, the flag is a nice touch, as much fun as a person can have with their clothes on. Keep up the hard work
I'd agree, but it wasn't a literal 'basket case' like ya see sometimes, so ya start to assume the seller did some easy wiring mistake or something if you're lucky. Don't always get lucky though
If you take the top end apart I'll bet you find that the rings are not staggered properly or in upside-down. Anyway, great job on the repairs you did. Thanks again for your time today and enjoy the rest of your weekend.
Yup that's happened to me on an old Briggs on a 70s garden tractor. I never knew some rings were directional - and neither did they guy who was in there before me apparently 😂. Good reason to read the manuals.
that's what I was thinking too, either rings or valve system. Really runs great Joe, you did a superb job! I've never seen a woodruff key shear off like that.
great video Joe, yeah could be valve stem seals, rings not spaced properly, or ring in upside down, interesting to see what the cause is when you tear it down. I love tearing down, and rebuilding heads, lapping valves, it's fun for me lol.
Yeah joe looks like your right I would say valve oil seals as well either that or rings and oil ring as well soon find out 😉look forward to the big reveal other than that still a good buy sounds good feel sorry for the neighbours right enough haha take care mate and all the best to you all 👍👌🔧🔧🔧❤️🏁🏁
Also changing that over to a 700 hopefully thr guy put the right springs and made the right adjustments for the clutch, they are set up differently between the 600 and 700, you may get alot more power and speed out of it changing the clutch to 700 springs
If original owner messed that much already. I’d be pulling apart jug to inspect everything like are ring ends staggered and piston circlips correctly installed
Reminds me of the gazillion marine gearboxes I've worked on. There is no cheating with gearbox seals. Don't care what weekend plans you've got. Put the tools down. Get the right parts. Do it the right way.
as someone who has been doing this stuff for over 20 years i got to say you have the diagnosing skills that many people with even my experience lack. i love this channel, keep up the good work joe
What kind of piston and cylinder kit? eBay chyneisum perhaps?? Let’s see a compression and leakdown test. Heck even a bore scope. It might have a set of those high performance oval piston rings from across the pond.
I sure hope the guy who rebuild this motor in the first place watches this and learned something. Otherwise he should probably NOT work on engines!! Wow.. Hey, at least you know what to do and can fix it. You got it for a fair price too so that's a plus.
That's a mechanical seal. The "STONE" as you call it is ceramic and the other part on spring seal is a carbon. Your not supposed to touch those faces. It will make it Leak prematurely.
i have a 2004 polaris 700 sportsman had it for over 4 years just do oil changes never let me down --- if i remember right they only have valve seals on the intake side -- i wonder what kind of kit he got could it be a china kit if yes thats your problem --- i also seen i guy take a 700 turn it into a 800 --- good luck -- great video like always
Yeah, I agree on the rings. That's a lot of riding for it to not clear up. I've done the same with one of my top end builds and didn't get the rings on correctly. Happens to the best of us. But yeah, new valve seals too.
Great video. It's challenging and I bet frustrating finding and fixing other people mistakes. You have to be very skilled and knowledgeable to take on these projects. Thanks
Ok for the smoke. Check the spark plug, does it have oil residue on it? Pull the exhaust and look into the head, you can look up the exhaust ports and see the stems of the valves. If the exhaust valve seals are bad you will see the oil seeping down. It’s not real easy to look at the intake valve seals and oil leaking because the fuel coming from the carb washes the oil off. If the spark plug looks oil fowled. It’s ether intake valve seals or oil scraper rings. If the spark plug looks good it’s exhaust valve seals. I’d say it’s not the piston rings. Because you have such high compression, I’d bet more on valve seals.
May not of replaced the valve guide seals or the rings are in the wrong order. I commented before you talked about the seals. Great vid thought. Keep up the good work.
I'm with you I can't stand loud exhaust. People seem to forget that if you have somebody riding behind you they gotta listen to that droning can drive u nuts. Gust don't see the point unless you're making some real horsepower but that's a whole different thing all in itself.
Put some Citronella oil in it, and you can use it to keep the Mosquito's away?! 😂 Considering how bad the water fix was, he probably flopped the rings or didn't torque the topend correctly, check the oil again for milkyness...🤔
Tear down all the way to rings...hopefully he didnt gouge the tub wall...with the mistakes found already there is sure to be more than one more in the top end
A more appropriate title should be "Seller made a series of huge mistakes on this $700 4X4 ATV" given the broken key, timing off, crappy silicone job rather than replace gasket/seal, not using Loctite on valve threads...wow...I'd never want to bring my 4wheeler to that guy for "repairs".
It's not "smoking" per say.. but it definitely has a very good mosquito repellent exhaust system installed... now THAT is worth the money.. lol.. runs great, though.. CHEERS!!
Your a good mekanik lol anyhow i have a similar 05 700 polaris and reverse quit do you have any ideas i can try before i pay someone to work on it i know its a stretch bit I figured what the hell i would thro it out there!!
Can't wait to see what surprises you find when you take the head off It's probably the valve seals but I still think you're gonna find a few more Issues besides that.
I think you made a HUGE mistake by putting in 10w40 conventional oil in the crankcase. It calls for 5w50 full synthetic oil. These engines aren't an old Honda or Suzuki where older oils are prevalent. When an engine calls for full synthetic, you use it. Whether that helps the smoking or not, you don't wanna "smoke your engine"!! For a cheaper alternative to Polaris oil, use Mobil 1 0w40 full synthetic.
I admire your patience and logical thinking diagnosing the issues. I used to strip and rebuild UK Mini's in my late teens in the 70's. Never had much money and needed to continually repair to keep on the road to get to and from work.

Dude. You absolutely made my day when you said check these bad boys out concerning the flags. I haven't heard check these bad boys out for years .
Looks like you are crop dusting....lol. You are a master of fixing other people's inept repairs. Some people should NEVER EVER work on mechanicals. Great job!
I have an 02 and watching this was very helpful just to watch if I come into these problems. I thought it was the timing from the begining but you showed it was much more then that! Thanks!
I think just seeing the way the valves were loose, I would have completely rebuilt the motor.❤
stfu i rebuilt it correct

Yup that's happened to me on an old Briggs on a 70s garden tractor. I never knew some rings were directional - and neither did they guy who was in there before me apparently 😂. Good reason to read the manuals.
Second ring upside down, messy engine building.
that's what I was thinking too, either rings or valve system. Really runs great Joe, you did a superb job! I've never seen a woodruff key shear off like that.
Love this small series
Was interesting he read up on things about that pump washer. Wish I had that skill.
A 4 stroke that identifies as being a 2 stroke 😂😂
Is a transsmoker
Somebody had to say it lol
Someone actually called that a rebuild. YIKES. Good job on our part.
Looks like the valve seats are bad or the rings not being seated
Valve seals I bet
Definitely seal valves.
Or both
Well you brought it back to life. Hope you find the issue of it smoking. Can't wait to see what ya find. Thanks for sharing.
great video Joe, yeah could be valve stem seals, rings not spaced properly, or ring in upside down, interesting to see what the cause is when you tear it down. I love tearing down, and rebuilding heads, lapping valves, it's fun for me lol.
You are great. I don't know where you are located, but I sure learn alot watching you fix there machines. Thank You
Yeah joe looks like your right I would say valve oil seals as well either that or rings and oil ring as well soon find out 😉look forward to the big reveal other than that still a good buy sounds good feel sorry for the neighbours right enough haha take care mate and all the best to you all 👍👌🔧🔧🔧❤️🏁🏁
Valve stem seals were what I was thinking, when I saw the smoke. Looking forward to the next Video !
Best of Luck, and hard work. I am sure you can fix this. Do it.
As long as the previous owner did not split the case you should be okay. Especially with all your awesome skills. 😎 👍
I get concrete mixing trays at Menards for catch pans. Works great for keeping the messes down.
Love your positive attitude. ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️
Also changing that over to a 700 hopefully thr guy put the right springs and made the right adjustments for the clutch, they are set up differently between the 600 and 700, you may get alot more power and speed out of it changing the clutch to 700 springs
If original owner messed that much already. I’d be pulling apart jug to inspect everything like are ring ends staggered and piston circlips correctly installed
I don't know how fast you were going but it didn't seem like it was going very fast..that thing should go 65 to 70 MPH.
Reminds me of the gazillion marine gearboxes I've worked on. There is no cheating with gearbox seals. Don't care what weekend plans you've got. Put the tools down. Get the right parts. Do it the right way.
I can smell the oil burning here in Michigan through my phone.
Check the valve guides and replace the seals
I've seen people use zip ties on the backside when your plastic welding it gives you a little bit of plastic to work with you just melted all together
as someone who has been doing this stuff for over 20 years i got to say you have the diagnosing skills that many people with even my experience lack. i love this channel, keep up the good work joe
Watching you ride is like watching a Camarata video.
I enjoy watching your show you do very well at it
great video , i would diffantly change the exhaust to stock or less noisy
Hey Joe.was wondering how you decided those washers were wrong? Cheers
You forgot to change the oil filter when you did that 600 twin?
JOE You Looked Like MOSQUITO CONTROL CAME EARLIER TODAY TO YOUR PROPERTY LOL😂
It's the rings or valve seals
What kind of piston and cylinder kit? eBay chyneisum perhaps?? Let’s see a compression and leakdown test. Heck even a bore scope. It might have a set of those high performance oval piston rings from across the pond.
I sure hope the guy who rebuild this motor in the first place watches this and learned something. Otherwise he should probably NOT work on engines!! Wow.. Hey, at least you know what to do and can fix it. You got it for a fair price too so that's a plus.
It runs very good and compression was excellent, I’m leaning towards valve seals
Great video. I love watching these videos 👍.
Love your channel mate, I couldn't turn a wrench to save my life.
For a Young Man, your technique is definitely Ol Skool. Keep up the good work!!
Another pile of Polaris junk!
If it was rings they would of seated relatively quick. Seeing the work at water pump is all you need to know.
backyard mechanics!!! they need to watch you before they cobble something up!!!
That's a mechanical seal. The "STONE" as you call it is ceramic and the other part on spring seal is a carbon. Your not supposed to touch those faces. It will make it Leak prematurely.
i have a 2004 polaris 700 sportsman had it for over 4 years just do oil changes never let me down --- if i remember right they only have valve seals on the intake side -- i wonder what kind of kit he got could it be a china kit if yes thats your problem --- i also seen i guy take a 700 turn it into a 800 --- good luck -- great video like always
Good job Joe, it reminds me of something stone cold would ride
Lol,this water pump seal looks good let's permatex it lol, a dumb way to not (fix) it,good thing Joe is smarter than that guy was
The previous owner did a hack job!
Bad valve guide seals usually let out a big puff after idling a while or after being parked and then restarted. A constant roar of smoke, rings.
You do great work i think a atv motorcycle lift would make things better ex motorcycle mechanic here
Yeah, I agree on the rings. That's a lot of riding for it to not clear up. I've done the same with one of my top end builds and didn't get the rings on correctly. Happens to the best of us. But yeah, new valve seals too.
good progress, i love watching ur videos and eating a burger or something lol
You should lubricate the faces of the "mechanical" water pump seal. 😮
The guy who rebuilt this thing was so bad with motors, everything he did was wrong
Great video. It's challenging and I bet frustrating finding and fixing other people mistakes. You have to be very skilled and knowledgeable to take on these projects. Thanks
new piston rings needed...at least
I hate to burst your bubble but the smoke is getting worse.
Never let corrosion get on your shaft.
Good luck keeping it off lol
I try not to but you never know how many shafts have been in there before yours.
What else did the guy hack when he rebuilt it? Cropduster.
I like to run my hurt oil burners at wide open throttle until they fix themselves too.
Valve seals thanks much 😢😅
Ok for the smoke.
Check the spark plug, does it have oil residue on it?
Pull the exhaust and look into the head, you can look up the exhaust ports and see the stems of the valves. If the exhaust valve seals are bad you will see the oil seeping down.
It’s not real easy to look at the intake valve seals and oil leaking because the fuel coming from the carb washes the oil off.
If the spark plug looks oil fowled. It’s ether intake valve seals or oil scraper rings. If the spark plug looks good it’s exhaust valve seals.
I’d say it’s not the piston rings. Because you have such high compression, I’d bet more on valve seals.
Makes me miss my old 800 Sportsman...Great video yet again!!!!your crushing it.
Happy 4th of July!👍🇺🇸🇺🇸🇺🇸🇺🇸
could be valve seal or maybe ring gap if they are all the same side he make few mistake so i guess he could have done that too haha nice video joe !!!
May not of replaced the valve guide seals or the rings are in the wrong order. I commented before you talked about the seals. Great vid thought. Keep up the good work.
Great job, always a teaching moment with engine rebuild.
It's obvious the guy did not know what he was doing.
Maybe 1 more oil change will sort smoke or valves seals mate 🤔
Joe Sherlock, nice detective work.
Just finished watching your videos on the mini boat. New sub, nice work.
I would loose that exhaust first thing.
I'm with you I can't stand loud exhaust. People seem to forget that if you have somebody riding behind you they gotta listen to that droning can drive u nuts. Gust don't see the point unless you're making some real horsepower but that's a whole different thing all in itself.
Sounds like a 700cc weedeater.
I wonder if when the guy put the rings in he didn't stagger them correctly knowing how he did everything else I could just imagine...
Put some Citronella oil in it, and you can use it to keep the Mosquito's away?! 😂 Considering how bad the water fix was, he probably flopped the rings or didn't torque the topend correctly, check the oil again for milkyness...🤔
Great job, good video, tearing into an engine is always a learning opportunity.
Tear down all the way to rings...hopefully he didnt gouge the tub wall...with the mistakes found already there is sure to be more than one more in the top end
The way it's smoking looks like those old 2 strokes with way to rich of oil to gas mix
Thing sounds like a chainsaw lol
Probably that aftermarket exhaust it don’t look like it’s anything nice appears to be homeade kinda lol
you never know what your going to find when you buy something someone said they rebuilt, but after all you fixed, looks like you got a good deal
Like your videos dude.
Love your videos buddy. Very informative
And he disappeared in a puff of smoke,like a magician
Seeing the rest of this guy’s “work” I would have gone back through the piston install.
It just identifies as a 2 stroke lol
Underrated Comment!
😂
😛😛😛😛😛❤❤❤❤🦾🦾🦴👍👍👍👍👍👍👍
I would seriously question the rest of the sellers work on that machine after what you showed.
Couldn't agree more... But I certainly don't question your skills at being able to swing any future issues for the price you paid.
A more appropriate title should be "Seller made a series of huge mistakes on this $700 4X4 ATV" given the broken key, timing off, crappy silicone job rather than replace gasket/seal, not using Loctite on valve threads...wow...I'd never want to bring my 4wheeler to that guy for "repairs".
Do you have the full videos of your rebuilds? And if so where can I find them?
I had a Honda 400ex that was rebuilt with the same smoking issues. Took it apart and they had all the gaps lined up 😂
It's not "smoking" per say.. but it definitely has a very good mosquito repellent exhaust system installed... now THAT is worth the money.. lol.. runs great, though.. CHEERS!!
Your a good mekanik lol anyhow i have a similar 05 700 polaris and reverse quit do you have any ideas i can try before i pay someone to work on it i know its a stretch bit I figured what the hell i would thro it out there!!
Can't wait to see what surprises you find when you take the head off It's probably the valve seals but I still think you're gonna find a few more Issues besides that.
You're videos are great...sometimes I think I'm watching Steve from Blues Clues in 1997...LOL!
I think you made a HUGE mistake by putting in 10w40 conventional oil in the crankcase. It calls for 5w50 full synthetic oil.
