- I take the 2003 Trailblazer 250cc with the cheapest top end kit installed on it and give it a test ride. I go as hard as I can, and try to really break it in to see if the kit can hold up. Will the cheapest top end piston and cylinder kit hold up? #Polaris, #Test, #Cheapest,

Well if you ran KLOTZ 2 stroke oil then you'd know if it was getting any by the exhaust smell because I had one of these and it was like brand new and they don't smoke at all really but it was getting proper oil mixture 🤷♂️
I also spent the few bucks and had my clutch rebuilt and wow did that make a huge difference lol it would creep forward at idle and could actually lift the front end after she got rebuilt and it didn't cost me barely anything!
17:35 the piston rings expanded like a balloon .006 ring gap was not enough n seized against the cylinder wall...lucky it didn't break the piston...File the ring gap
I had a 2006ish that I got brand new, I must have had 800+ hours on the top end without ever doing maintenance. I’m now a Maintenance freak, but seriously, that Fourwheeler would
Not die. It was either wide open throttle or full brake application 24/7 too! Unreal
Ive rebuilt several top ends with niche parts and none of them have blown. One of them being my personal atv with over 2000miles on a rebuild i did 4 years ago
Alot has to do with the way u build it and break in too i just did a niche kit and it sounds nice still have to break it in thou
Do u trust the self oiling injection...or do u mix the oil an fuel ur self...
@@shawnlibby675 I have a trail blazer 250 and a sport 400 and surprisingly the self oil injection works great on both
I had a 1997 trailblazer 250 I believe it was and it went 53mph with me. Flat ground that was the fastest I ever gotten it. Suppose to been all stock just tuned the carb
Congrats on the 200k subs joe almost there 👍
Great video made my day a lot better ❤️
I also love that you do top speed runs Bro, Thank you for that!
Very good video as always!
Nearly 200k subscribers 🤟🏻 your killing it Joe..
Waiting all morning for this
Can you make a shop tour video? I'd love to see what tools you use and recommend. I wish you would take more machines apart paint them up and make them look as good as this. I love all the builds and good job
That’s probably the cleanest trailblazer 250 I’ve seen. The one I had was in really rough shape and it didn’t run, ended up trading it for a 2001 cr80. You should try a trail boss 250. Almost the same thing but I think the trail boss was a little bit more torquey. I had one and it was a nice little bike. Not sure of the year though I don’t think I ever looked it up.
I think it was a 1996, not too sure. But rumor has it the trail boss is supposed to go around 54-55.
I just bought a trial blazer 250 watched your rebuild on the top end an the testing made me even more excited then I am seeing how esay it can be I gotta fix my electric start an some time been sitting for a while
Good info iv heard a lot different stuff about these kits good to know
I did a rebuild on a 97 rm125 with a 27$ namura piston kit. Works great so far.
Nice! I have a 1996 rm125. Love those bikes!
I dit a namura top end kit on my 98 rm250
I find with the cheaper kits just run them in good and there fine
Namura in my Blaster. Namura are actually very good pistons.
@@tibrin7696 im kinda shocked they work so good for the price point
Great job joe runs great cracking build mate. 🔧🔧🔧👍👌
Awesome vid and edits and filming and bikes
Can’t lie, to me it sounds very lean right off the trailer. I knew this was gonna be a fun video 😂
Awesome video brother very helpful
Awesome video man
Another Great Video, The Niche Topend Survived!!
Good job !! Hello from Sydney Australia! We still under lockdown here .
Haha thanks to you guys we in Newcastle are now in lockdown haha
Heck yea Joe Joe keep buildin them ringa ding dingers bub
Always use premix for a couple of tanks on a fresh topend
He did
@@rustrenegade8191 he said at the start of the video that he didn’t for the first two start ups
@@dhan7072 so Wuts your point
@@dhan7072 with an oil injector so you don’t have to mix it
@@toxicplague6278 no he means use pre mix with the oil injector. Because you want the extra lubrications since the rings are fresh and tight and also they have to wear and mate to the cylinder for a good seal.
Love the vids
I used an Amazon top end kit with jug for my blaster and I beat the hell out of it for months before the bottom end locked up cause the bearings were bad and I got the blaster for free so I didn’t care. I can’t complain about the cheap stuff if you break it in right it seems to be pretty decent
So trailblazers and Polaris 250 are bout same in speed to blasters , 200 yfm ,any 2 stroke 80cc , crf 150f ?
Your almost at 200k!!
As a diehard Honda man . My first quad when I was 12 was a 91 trail boss 250. One of the best I’ve ever owned
I know a diehard Honda guy and he says these things were meant to ride and hard to kill. I recently just got my first quad and it's a 98 trail boss, an old guy had it then the kid I got it from. The kid I guess tried drifting it with the chain way to loose and it smacked a hole in the gear case when it broke so we are having to fix that before i get to ride this thing. Already did the seal because it sat for awhile. Ol boy told me to apparently it's got a new top end no idea what brand but it's only got 8 hours on it. I'm beyond excited!
We got it for 100 bucks and the only rusty parts are the battery tray and all of the exhaust.
Run it hard!!!! That's a nice quad man . Fix it right.
Check engine mounts I thought I seen it move when you were working on the rebuild
I had a 95 UGLY!!!! White and sea green. I beat it up constantly. Never quit on me.
what part of wisconsin you at? come up to the yoop and hit some trails!
I like the scenery out there. Be safe my Friend :)
Upper midwest is BEAUTIFUL
@@Davido50 Im in the mid-midwest lol Missouri but was born in Iowa, miss the north!
@@j-beatsimaginationstudio1987 Absolutely 💯 👌 im back an love it! Never leave again.
I like that grey/silver color for sure. All I see are Red,Blue, and white ones out here in AZ.
Who maintains those trails? I see that ATV route sign when you pull into the field.
Wisconsin has lots good trails 👣 👍
I just put a niche top end on my Polaris xplorer 400 which is pretty much the same thing. I have found that the ring gap is too tight, which is why on the top speed run it is seizing up . Same thing happens to me and I am just trying to break it in before I do the full speed runs . Either way the hubs are leaking and I can't ..polaris sucks the more I work on them I find I spend too much time working on them .
Polaris are fun but yes, it seems when one thing goes it’s a non stop repair item. One thing after another.
Love the vids keep up the good work
Thank you!
It's a nice looking machine, but it sounds like an old snowmobile... probably because it's set up just like one... But it's still cool... Thanks for the video.
It is ! Not a bad thing tho.
Might need a bottom motor mount or something under the seat my cousin has a a trail boss and his motor mount is bad on the bottom and raddles a lot
I had a 250 Trailboss when i was a kid. yours sounds like its not revving out as much.. too bad there wasnt a tac on it.
Wow that really held up well
I always blank off the oil pump on theys 2stroke quads an use pre mix all the time puts my mind 2 rest
What app do you use to track speed? I have dozens of quads, bikes, and carts that I've wanted to try, but would like a reliable accurate app. Also always love the content bro🤙
Good job
Should get the plastic cover for the right side down by the foot break
hello,
The part about bleeding the oil pump needed to be explained better.
Beautiful landscape there, very green.
It's a cool bike, but the cost of parts here in Portugal is insanely expensive.
hug from Portugal.
I also put a niche piston on one for a buddy and it ran like a bat out of hell
Sounds went from legendary 2stroke sound to something that sounds like a grinding rattle.
Do they make this kit for the 330 4-stroke?
What websites do you look at the most when looking for quads/dirt bikes?
i like how upper midwesterns put a lot of emphasis on the Os like the canadians.
My first atv was a 2000 trailblazer 250
That stall could be air in the lines, I had a friend who had a polaris trailblazer and it did the same thing
Kind of recognize the registration stickers and road signs. You in WI? What part? Im an enduro bike guy but just got into older, lighter small bore atv's and having a good time during winter on them here. Sheet metal screws for studs!
lmfao love the intro oh ohh thats not good lol
What part of Wisconsin are you from? I’m from around the fox valley.
The best notification when you post
Let's get it
i will agree with others and say it sounds like its running lean, this could be why you are running faster than spec. the idle doesnt sound quite right.
nice beginner quads for sure. we had one when i was young like 10-12, really loved riding it. dad sold it unfortunately
you should try and track down a yamaha tri-z 3wheeler, i bet it would beat the tecate 3
Tecates where the fastest in a straight line atc had by far the best suspension I love my triZ but It doesn’t keep up with my 86R or my buddys 86 t3
@@cadenoquinn6154 I have a t3 and it’s stroked to a 300😂 bad decisions
Try to find a first gen can-am outlander
My yamaha dt 50 has a 37e 90cc kit on it and the only thing i did i ported it and honed the cilinder the bike is a rocketship
Making a small prediction before I watch the complete video the rings may give you an issue. And I hope the head stays torqued down the piston should last for a while but hey good luck with it let’s watch and see what happens
Runs like a Polaris …. Nice
Whoever thought that a bright yellow washing basket looking thing would look good on that machine was dead wrong
Wonder if it’s like the. Polaris jet skis…….Fuji imvac motors! It does sound a touch lean though
The MacPherson struts are cool :p
My buddy had one of these when we were kids. That thing road like a Cadillac in the trails so the struts must be pretty good.
What year model is it?
I'm rebuilding my 250 with the same kit. Its been 2 years since you posted this vid, did that quad ever fail?
I bought a gold xring chain from that same company.niche.has not stretched at all..60 dollars .it's on a kx450f.
17:02 ATV ROute???? where is this magical place lol?
Does it have a bad motor mount? That could be the noise you’re hearing. In the first video when you were taking the spark plug out I thought I saw the motor rock back & forth.
i noticed a lot of movement as well when he was working on it
@@maxtheroofer8004 definitely can’t be good for the clutch & belt either
I had noticed the excessive movement n just figured that bracket he removed to get better access was a motor mount n passed it off. But that was ALOT of movement so might be a good idea to give that engine a good shake, hell go around it with a pry bar even
The turning off in the start of the video was a heat seize, it must have just been quick so the piston rings, piston and cylinder all survived.
Sounds like its idling a little high?
Minimum ring clearance in this motor is 9 thousandths according to service manual 6 is way to tight
Definitely sounds lean, that choppy return to idle on deceleration.
you got a one year update for us or what my g?
I rebuilt a Suzuki lt80 with a niche too end, does the same thing at top end for a while, just like it chokes out, than will fire right back up…
Ring end gap too tight
Buy a scrambler 500 I have one it's so fun
Do y’all know why a Yamaha grizzly would lock up over knight idk what happened to it it was free the day before
So it was running day before? Maybe hydro-lock. Carb overflow into cylinder. Does the carb leak?
@@kernelbadness it wasn’t running but u could pull the rip cord then the next day went to see if it would start but it wasn’t moving
Yeah I did 56-58 mph on mine with original piston and all original parts... not sure where you read 45mph lol
I have had good success with the NICHE cylinders they have proven to be high quality. But I would never use a NICHE piston witch commonly are the reason for failure.
I predict that if you removed the cylinder you would find a scored piston. It's running lean!!!!!!
Hope it last forever 🤘🏻
Driving mine till it blows up so I can put my 488 fan cooled snowmobile engine on it
Can tell by that idle that it's running lean
I have a question, why does he always have 250s or fixes 250 quads. Is there something special about 250s?
as an owner of alot of older polaris they will almost never blow up unless you install a wrist pin incorectly... happend to me
How do u put a wrist pin in wrong?
I would have let it keep going far as top speed test,u let up at 51mph..I would have keep it pegged and see what top max speed was!..And niche is really good equipment from a user..Nice job on upper rebuild thou.
that sounds like the cvt clutch is going bad
I put a 32 dollar top end on a Suzuki lt80 and rode that thing hard and 2 owners later it still runs
I find that with new top ends you really have to take it easy the first few rides
Clean little machine
check your plug.. could be running lean...
Thing sounds like an snowmobile
I would never rely on oil injection, I would bypass that system and premix my gas.
Mine would go 65 mph with sprocket change
That thing is super slow haha never drove one of those before so not sure if its normal haha
Good afternoon good sir 😎
You mean morning
Nope, afternoon here in the uk 😂👍🏼
@@robquattro5419 oh lol 😂 I live in Minnesota
hey 2vintage, this is 1oldguy who was just wondering if you are a mechanic by trade. Either way your channel is cool.
Also another thing to keep in mind he said he premixed the fuel in oil which means he leaned out his fuel air mixture because he does not have the proper Jets to run pre-mixed fuel through the carburetor if you don't understand when you mix two stroke oil in your fuel and you are running an injector the jetting is set for straight gas not mixed meaning it needs more mixed gas then raw fuel when it is injected hence causing a lean condition which will burn out your top end in 20 minutes way to go there smart guy
That thing sounds like a hamster wheel🙃
Hi.. just wondering if you were interested in trading that trail blazer for a 1988 Suzuki 185 runs great looks really nice to. It would be for my girlfriend I think she would like the Automatic.. we can add some cash too. So what do you think ?
