Trying To Break The CHEAPEST Top End Piston and Cylinder Kit Installed On a Quad. Will It Hold Up?

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 🤷‍♂️

[@kevinAuman1]

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!

[@aspenyukon6845]

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

[@jeffsmith7247]

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

[@Smallenginetech56]

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

[@rexs8058]

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

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

[@Cwmarlowe]

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

[@theredneckgarage1493]

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.

[@theredneckgarage1493]

I think it was a 1996, not too sure. But rumor has it the trail boss is supposed to go around 54-55.

[@larrywarner9314]

[@worldrage619]

@@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.

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

[@mikemeunier846]

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

[@stephenmcdermott1218]

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!

[@stephenmcdermott1218]

We got it for 100 bucks and the only rusty parts are the battery tray and all of the exhaust.

[@maxtheroofer8004]

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

[@cadenoquinn6154]

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

[@ronlagasssvolgs6126]

[@inductionsymphonytrd]

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 .

[@Erix7810]

Polaris are fun but yes, it seems when one thing goes it’s a non stop repair item. One thing after another.

[@joelbullock61]

I had a 95 UGLY!!!! White and sea green. I beat it up constantly. Never quit on me.

[@MintMonte87ACSS312]

Can’t lie, to me it sounds very lean right off the trailer. I knew this was gonna be a fun video 😂

[@JoshX9]

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

[@glenwhitacre2754]

Check engine mounts I thought I seen it move when you were working on the rebuild

[@briancrull8678]

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

[@briancrull8678]

Runs like a Polaris …. Nice

[@jonnyonwheels]

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.

[@maxtheroofer8004]

i noticed a lot of movement as well when he was working on it

[@jonnyonwheels]

@@maxtheroofer8004 definitely can’t be good for the clutch & belt either

[@benmiller5015]

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

[@jnkfishing9274]

Minimum ring clearance in this motor is 9 thousandths according to service manual 6 is way to tight

[@michaelthomas788]

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
