You have tons of young ones watching you. Please do it the correct way. They learning from you. If it was getting fuel to the gas line, putting fuel in same inlet port will do nothing. Put some in the spark plug hole. Then if it starts. You know it’s the carb needing a tear down just because gas goes in the carb means nothing. Keep up the vids
@@jaydensdream714 I actually am serious man . This is standard diagnosing practice. Ignoring the fact it had no compression . We are talking about fuel delivery only . Who in the hell pulls a carb and cleans it if you don’t know fuel delivery is a problem . One minute it takes to pull the plug and put a few drops of fuel in and see if it fires . What the hell does dumping fuel in the in the inlet port if the carb do, knowing the fuel tank was dumping it in there . Not a god damn thing. That’s what . Guys like him have a following of young kids learning what he does . That is the reason I call him on some shit that isn’t proper procedure.
@@jaydensdream714 Thing is I’m sure we can get along great I watched a couple of your videos it’s hard to express your feelings and talk without sounding like an asshole on TH-cam
Jep, 100% overheated! There’s a splitter so the oil pump is connected to the throttle. Worked alot on 2stroke engines with these kind of oil pumps. I suggest to premix the gas with oil so its way more reliable. I’ve seen alot of engine’s seized due this problem.. good luck man! Greets from the netherlands
@@backyardbangers1012 depends, if the engine was locked up when it overheated it could’ve messed up the botten end. Howerver, looking at piston (and rings) and cilinder it looked like it expended just enough to seize. He should check the crankshaft for play. Its oke to have a little play but not to much
@@backyardbangers1012 they may have had that already. Normally a 2 stroke that heated up to much 1 time only messes up the piston (rings) and cilinder. Especially at low rpm
Hey, I used to save the same quad. Mine was called a Kolpin 90. Kolpin was bought out by polaris and then Polaris made the Predator 90 to be a replica of the Kolpin 90. I used to have the same problem as what your having but when I had replaced the top end, I only had put new gaskets since the new piston and rings didn't fit due to me needing to bore it out. It still didn't run after that either. It wanted to but I always needed to keep my finger on the throttle because otherwise, it would die. You should check the reeds as well and see if they're good! I never knew it had rings until I took the carburetor off and found out that there were reeds right behind the carb boot. Hope you get it fixed. Great vid with information.
I've seen a lot of mechanics age prematurely, mostly because of their inability to handle stress. You seem to have a great attitude about any situation you encounter and I have no doubt that you will be successful in the business in any capacity you choose. It looks like one little thing started a chain reaction of destruction in that engine. I wonder if the plastic part that connects the 2 lower cables to the upper throttle cable has snapped, or maybe it had been reassembled incorrectly when the upper cable was replaced. Hoping you get lucky with the crank bearings. They do retain a little lubricating oil after the cylinder has burned through it's last drop. Looks like possibly an easy fix.
I’m definitely following this, I need to rebuild my 90 and I keep getting people telling me that those kits are awful, thanks for testing it for me haha.
So you have to b careful when you delete the oil pump.you really need to re-jet when you do that because the stock jetting is for straight gas.when you mix 2 cycle oil in the gas,it becomes a thicker liquid, and you can only squeeze so much through the already lean stock jetting!! Just a little tip from a 50 plus year old master technician.
Where would they sell those? Mine will run for a few seconds and die but ive cleaned the carb and put a new sparkplug on it still has the same issue and it will only run on ether so i might be mixing the gas wrong please let me know
can you please explain how you got the stator cover off... that part was skipped, i have a 2001 and can't figure out where to start taking plastics off.
I'm sure you know this but you can hold spark plug to any part of the frame it doesn't have to be the engine case as long as case is grounded to frame.
14:10 ur loosing compression true that leak, that squeak noise u hear when cranking is air escaping thrue that gasket. but idk I still gotta watch the rest of the video, just my guess
if that thing ran without any oil from failed oil pump tehn the bottom end is trashed aswell , big end probably has play or it will sonner rather then later
that's just typical maintenance on a Polaris. I did a top end rebuild on my Polaris and it ran great for a while, but now I don't think there is any spark.
Hey get a zoom spout bottle for your gas.get them on Amazon I use them they work great. They come with sewing machine oil in them .I used the oil then use them for gas
Get a eton viper 90 but get the two stroke version with the power band and cut the rev limiter wire of the Cdi box to make it more faster and more power I have one and there tanks
When your turning it over it sounds like the rings are non existent or I have seen quads break a rod and sounds just like that the motor is turning over way to easy

You need a container like Mustie1 has for putting gas in the carb
Oh and ask santa for a camera scope for looking in the plug hole and other areas of interest.....
Yo joe.. this guy has a 2014 Polaris sportsman 400 Ho stop running as well. What should I do??
what hapens to thosebikes is they blow a head gasket and run lean and over heat
do you still have the other 400ex
8:30 if we’re getting gas and fuel😂
🤣🤣🤣🤣🤣😂😂😂
It's getting gas and fuel😂😂

Looks like it might be time for a new ramp!
This is why you should always disconnect the oil pump and run premix haha
This guy is like a cris fix but for atvs and dirt bikes

is that ramp ok?
Those engines are used on a variety of quads and super sturdy
I love how the starter kept interrupting him
can you please explain how you got the stator cover off... that part was skipped, i have a 2001 and can't figure out where to start taking plastics off.
I think you are right this was caused by the oil pump stop working and caused a major melt down
Have a blessed Friday!
That's ah clean bike you don't see many in that color! Worth alot fixed.
This one is ruff, can’t wait to see the tecate
I'm sure you know this but you can hold spark plug to any part of the frame it doesn't have to be the engine case as long as case is grounded to frame.
I’m 12 years old and watching you and know probably just as much as you about quads. Lol
Probably more..
Like the way he was pulling back and front brake , and says yeah oil pump not working 😂😂😂
the guy was probably river riding and didn’t run an air filter. that’s how the rust and scratches got in there
You mean the kid? That thing wouldn’t have any power hauling a grown man
@@that250exc My kid's 90 has plenty of power, they're faster than you think.
Anything can be saved on this channel
What about air you should start checking the filter and the boot there might be some debree and that can get in the engine.
Awesome, minarelli type engine there's a plethora of parts for them
What website do you use?
70 dollar kit on eBay. I put one on my arctic cat 90 runs great.
I really like working on these ATV's they are a ton of fun to ride. putting on a BBK makes them really move.
every time he says "puwer" or "thradall cable" has me laughing to tears
I would be checking the crank bearings if it was ran dry then heated up, my best bet there scored.
the ramp gets yu every time
Great video. Hopefully mine is running on about step 3 of this video but we shall see.
Come on man....BUY A NEW RAMP!!! Lol.
Annoys me everytime
He is 2 cheap
You should get a Suzuki eiger 400 4x4 I have one and it's amazing
Nice harbor freight ramps
14:10 ur loosing compression true that leak, that squeak noise u hear when cranking is air escaping thrue that gasket. but idk I still gotta watch the rest of the video, just my guess
I love ur vids keep it up bro
Those 90s and 50s Polaris early 2000s are notorious for the stator going bad. Get a Rick's if that's the case
if that thing ran without any oil from failed oil pump tehn the bottom end is trashed aswell , big end probably has play or it will sonner rather then later
Where did you find the rebuilt kit? I can’t find any
I'm excited for the next video hopefully the next video for will be a first start
What did u buy it for?
When? When man are you going to get a new ramp? Lol jk 🤣
Let’s get a go fund me going to get this dude a new ramp😂
for real spends thousands on quads etc but cant spend 200$ on new ranks lol
@@reggiexp69 ain't broke don't fix it
@@bluegrassadventures8227 yeah its better to have some bent one that having none
that's just typical maintenance on a Polaris. I did a top end rebuild on my Polaris and it ran great for a while, but now I don't think there is any spark.
Did you save it?
My sister eton viper 90 quad is 17 years old and it has no problem
Hey vintage just thought I did this couples months ago get a smaller spray bottle and use it to spray in the carb
How
do you remove plastics on stator
side?
AWSOME good for you and what happens with the kx490?
Is it a 2 stroke
Joe buy a decent set of ramps please
Always look forward to the vids man..good stuff👍..Maybe one day you pick up a Bombardier DS650 🤔
Can you get a suzuki king quad or eiger or i have an 03 honda recon es i would love to see you work on one i would learn how to work on my own
Awesome video man
Looking forward to the top speed run on the ATV with a bigger rider. How much do you and Chuck weigh? You should do a comparison.
Can you do a big utility four wheeler pls
the crank will be toast
Should look for a kfx450 thats a nice quad
Was there a follow up of a new top end? Good video
Hey get a zoom spout bottle for your gas.get them on Amazon I use them they work great. They come with sewing machine oil in them .I used the oil then use them for gas
When are the new ramps coming?
You should get another Cr
Shoulda tried gas down the plug hole. Gas might not be getting thru carb. But it’s clearly got problems
get a kfx400 pls
Yes pleaseee
Will somebody buy this guy a new ramp already???
Some engines you Can't just stop using the the oil injection. Some have lines that go to bottom end
You should do a honda trx250ex build
Would you buy my 1985 suzuki 230 shaft
Should maybe take a look and price out some cheap Honda 700xx quads!.not many people even know about them!.
Get a KLX110, DRZ110, CRF110, TTR110 any of the 110 pitbikes
Nah
When you gonna upload on the 400EXs again??
Hey any website that has parts for these? I have 1 and im planning bringing it back bought it for 20$
They pulled the float bowl to high so less gas was going to the carb and did not have enough fuel to go up the hill
there is supposed to be a fan on the flywheel that cools the cylinder. Probably why it overheated
The squeaking noise is air blowing past the head gasket.
Get a eton viper 90 but get the two stroke version with the power band and cut the rev limiter wire of the Cdi box to make it more faster and more power I have one and there tanks
It will not start without a breather I have on would not pop over i got a air filter box and air filter and fired up and ran perfect
They Hydro locked it I think that’s why the head gasket was blown and rust in the cylinder
where’s the dirtbikes 🙁
Next video!
@@2vintage u should post more on dirtbikes
@@2vintage no complaints about this channel tho I love it
Trevør Ackert nah both
Good vid!
Come on man , here's the deal ( Joe Biden) fix that ramp 🔧🔩
Trump 2020
Trump2020

Trump 👍. Biden👎
Joe biden 2020
Been ran with no oil in the fuel no doubt
Yep I'm sick of seeing that ramp go limp every time.
Love your videos i watch them all down for a giveaway SOON ?
THANK YOU
this was for sale for like i think 150 or 200ish yesterday
crank bearings will sound like roller skates
Sounds like a bad head gasket when u are cranking it over
Please get a ltz400 or kfx400
list of things to do
1)fix the bloody ramp
2) buy a breaker bar
3) stop buying tractors
Top end rebuild
bike vid soon?
Where do you live
If there was a hole in the piston there would be zero compression like joe you have no idea what you’re talking about 🤣🤣🤣
I would think it was over heated
check how flat the head is by placing it on a flat sheet of glass.
When your turning it over it sounds like the rings are non existent or I have seen quads break a rod and sounds just like that the motor is turning over way to easy
Ya sounds like it spun a rod or the rod I guess
