Have you had a good or bad experience with aftermarket top end kits? Let us know about your experience in the comments below! Thank you for watching my video, you guys ROCK! 👊👊👊
Michael Sabo I hope you reply but will a lighter weight forged piston make less torque than a cast? It seems plausible to me since it would be less rostering weight but it would rev faster and easier
Made in Taiwan parts are usually ok to good in quality. Made in China parts are usually utter junk to ok in quality. Don't confuse the two - there is a difference.
I bought one of those holzforma knock off Husqvarna 372xp chainsaws from china. Also purchased the big bore top end for 16$, and the quality is surprisingly high.
Dude, I could literally see where the crosshatch stopped lower into the cylinder where the piston rings don't run down that far when you tilted the cylinder at 3:39
I got a cheap kit lol. Ran just fine, had tons more power, and had really good compression. Rode it for about three days then sat for about two days. Went to start it up and it was smokin harder than a freight train! Piston skirts wore down and chipped off and shaved the cylinder
It's just hard to trust off brand parts these days. I myself don't take chances because I've been burned by that issue before. I realize there's probably nothing wrong with them it's just preference.
Hey! I'm not the only one who knows the trick on making the cylinder head flat again with sandpaper. I have done that many many times. I've had people tell my I'm stupid for that and so on. I Would get rid of those Wire Nuts and Solder then Heat shrink the wire back together.
I enjoyed watching this video!… It was pretty good ..and I have a parallel twin ..and I’ve done this stuff before but it’s still nice to watch someone else do it LOL
Hello there! Great work on this video and repair! Is it possible for you to share a link for that top end kit you bought? I've been looking and so far I can't find one with that elbow on the cylinder housing. I would appreciate the help, thank you!
Unless you are going to run 150hp shot of nos you don't need a forged piston Also forged pistons wear out the cylinder walls quicker especially the nikasil coated ones Thicker pistons side walls means that it will expand more due to more material so you will have to run looser tolerances.
If your working on vintage Japanese bikes look for the ebay seller cruzinimage. Pistons are well priced, very close to matched on multi-cylinder sets, and very good tolerances.
Dont take it out for more then a test ride. Not an all day deal... You need to sell not fix it again. AWESOME job. I could have got a 2009 nice condition KFX450r for 600 bucks.. I passed because the case was taken out from a chain. Bike ran great however the JB weld he did was leaking pretty bad. New engine cases are expensive and who knows what ill find in a 10 year old race quad. I didnt make sense to me to buy it and have to completely rebuild the whole engine even if it was 600 bucks.
Do you have an update on the cylinder? I’m thinking about buying this kit and I am lil nervous about it. I will be using the piston that comes with it. Just gonna be a cruiser so not gonna be dogging it and making a mud machine out of if. Think it will be ok?
I would never put any cheap Chinese made junk inside my big dollar engine... Good way to cost yourself several thousand dollars because you want to cheap out on a major engine component to save a couple bucks..
Never use a 3m rolock disc to clean gasket surfaces they will cause high and low spots on surfaces from removing metal . seen heads and blocks have to be milled because of it.
LOL , The oem is like 5x weaker facts based its a forged piston factory is not best is what works and what they can get alot of cheap or they would make no profit take a ever take a rockwell hardness test to a oem piston ??? I have no even close to any forged aftermarket .
Pay the extra little money for the better internals now so later you don't have to spend a lot of money on a new engine after the cheap parts explode on your 3rd lap around your house.
nice video keep up the good work mike 10/10 content. i had a question about Chinese parts for stuff y can you find a ton of china top ends for blasters 400ex's banshees yz's ect but for some odd reason nun at all for lt250r's i have 2 that im building right now one a trick quad and one a ''beater'' but their are no parts from china at all you can not find a cheep top end kit cylinder pistons head the hole 9 like you can for a ton of other stuff i was just wondering y that is my first guess was age but that's not the case at all lt's are old just as blasters shees ect then i was thinking it was a brand thing that yamaha and honda were the only brands that you can find cheep china top ends for but no you can find the same cheep rebuilds for rm's ltz's and ltr's but y not the lt250r. if you mike or anyone can give me a answer on y this is or a place that sells legacy year lt parts (1985 and 1986) i would love the imput anyway keep up the good work love all the vids and i cant wait to see what 2 smoke 250 you pick next to do a build on trx250r or lt250r (ps the correct answer is lt250r duuuu ) ( and yes i know you have had one and know a lot about em and for you it might be a bit ''stale'' but for the people at home watching you might connect / interest more seeing as thier are way way more people that own lts and not trx's due to rarity and cost to up keep just some food for thought i my self would be happy with any one of the 2 ) have a good day -king0fversaibackinaction ;]
use china block yes but check it bore n throw piston n pin in garbage waffel mark forged othere one is cast be fine in a old 350 chevy stocker or a stationary engine but high flow japan atv or even polarasis never use china piston pins or bearings,,i got silicon gasket maker in a cheap gasket kit it was crap more clay in it than blinder brittle lol funny stuff
You almost need to run two toys side by side. One with cheap parts and one with known quality parts and just see what happens. I personally have only put quality parts on my toys. Can't afford the oops if it comes apart right away.
I bought a cheap top end kit for my blaster just to see what would happen because people gave it a good review. I tried it and the first start up would of course not stay started but it would never stay started. I took it apart and the piston rings were seized to the piston and the piston clips were melted to the piston. Dont buy cheap stuff
I've heard of people cold seizing their new pistons or just locking them up because they overlook these much needed holes fir 2-strokes with exhaust bridges. Cast pistons don't need them just the forged pistons expand more but I'm sure you know that.
You don't have a $25 digital scale....?!?! At some point in the past weisco was a new company producing low quality parts BUT they learned how to create better quality parts and developed a brand. So did the Japanese..and so will the Chinese.. If I knew that I created low quality parts and at some point in the future I would improve, I wouldn't put my name anywhere on the box.
You should definitely get rid of the house wiring b*******... soon as I saw that I was very disappointed. Up until that point it was good video. House wiring and Automotive wiring never work together ever.

Rotating*
Steven Broski no lighter stuff just moves faster. What you’re talking about is compression.

Nice job once again! Love to see a video of you ripping it around.
"Pistons always look cool, man" Could not agree more! Amen!
The cheap cast piston could be bore matched to the cheap cylinder. Shiny isn’t always better lol.

I’ve used cheap pistons on all my quads! The 2006 Blaster I paid 70$ for piston and jug, and that was 5 years ago. My son rides it pretty hard too

It only takes once to get a faulty part.
Rigguy yeah I understand 👍🏾 happy wheeling
@@dorianjames9798 you too
of course we want to see you ripping it up just make sure it has fuel 😂😂 great job keep them coming 👍👍👍👍
Love theses kind of vids on utility atvs and sxs racing atvs have never been my thing just figured I'd let you know I'm all for this content!

Cant wait for the next video. I really enjoy them

Wow I love how you actually used a torque wrench on everything
That random “say no to drugs” sign 😂 Great video!🤙
Yeah😂😂
Mike Sabo did the gasket kit hold up
The oil rings groove oil holes look nicely spaces and such too, also this knockoff looked heavier built (thicker) than the old knockoff..
I honestly enjoy watching your videos
@13:11 I think you should get a digital scale as you seem to be a bit confused on how to read an analog gauge.
Unless you are going to run 150hp shot of nos you don't need a forged piston
Also forged pistons wear out the cylinder walls quicker especially the nikasil coated ones
Thicker pistons side walls means that it will expand more due to more material so you will have to run looser tolerances.
So u r saying he shouldve stuck with the chinese piston, i dont understand what causes that excessive wear on the cylinder walls tho
If your working on vintage Japanese bikes look for the ebay seller cruzinimage. Pistons are well priced, very close to matched on multi-cylinder sets, and very good tolerances.
Great video i love to see the stuff ive never done before you can learn a lot 💯🔥🔥🔥

Also the cheap piston is poured aluminum and the Wiseco piston is pressed aluminum so it's much denser aluminum all around
i like how you weighed the pistons... thumbsup!
I would never put any cheap Chinese made junk inside my big dollar engine... Good way to cost yourself several thousand dollars because you want to cheap out on a major engine component to save a couple bucks..
I agree , but its not a couple of bucks.. the difference is a significant amount
@@chriscs9080 until the cost of engine repairs out weighs any savings by using junk parts.
Never use a 3m rolock disc to clean gasket surfaces they will cause high and low spots on surfaces from removing metal . seen heads and blocks have to be milled because of it.
i bought a brand new cylinder from Yamaha for my 04 yz250.. glad i cleaned it... pretty sure they mention that in the manual tho.
really wont bad... but... it dont take much to wear out some rings....
take the stator cover off the other side to turn and time
Awesome video 💪💪💪
Only thing better than Wiseco is OEM
LOL , The oem is like 5x weaker facts based its a forged piston factory is not best is what works and what they can get alot of cheap or they would make no profit take a ever take a rockwell hardness test to a oem piston ??? I have no even close to any forged aftermarket .
Great video. Darn near spit my coffee out at the Zebra head. Lol
Hey anyone ever heard of namura piston kits? Think they good for a banshee?
Do you have a link for these kits
keep up the good work bro!
Love your videos bro!!
Great content, man!
Nice job. I’m building a banshee I will send you pictures on Instagram when it’s finished
Pay the extra little money for the better internals now so later you don't have to spend a lot of money on a new engine after the cheap parts explode on your 3rd lap around your house.
Mike where do you get your services manuals from?

Nice!! Definitely gotta rip it
use china block yes but check it bore n throw piston n pin in garbage waffel mark forged othere one is cast be fine in a old 350 chevy stocker or a stationary engine but high flow japan atv or even polarasis never use china piston pins or bearings,,i got silicon gasket maker in a cheap gasket kit it was crap more clay in it than blinder brittle lol funny stuff
U should resit the valves for better seal meant
When you buy new for the most part you get what you pay for quality
HF oil filter is a good quality filter.
Have any TV networks hit you up on starting a show? Seriously Mike keep up the good work brother!
You almost need to run two toys side by side. One with cheap parts and one with known quality parts and just see what happens. I personally have only put quality parts on my toys. Can't afford the oops if it comes apart right away.
take the timing flywhel cover off, lots easier than than belt cover
That'd be lighter reciprocating, not rotating mass lol. Honest mistake. Thanks for the video, i love these comparisons.
U can check scales using a nickel they way 5 grams
Looks like a standard sportsman air filter 7082101 instead of 7081308
To get a flat surface to lap to try using a piece of glass to put the sandpaper on. Most glass is relatively flat.
Great video
Thank you for watching man!
Definitely take it out for a rip!
Where did you locate the service manual?
continuously variable transmission (CVT)
Wiseco now has a sticker on the boxes and if the seal is cut it's been tampered with and may have a different part.
It would be cool
I bought a cheap top end kit for my blaster just to see what would happen because people gave it a good review. I tried it and the first start up would of course not stay started but it would never stay started. I took it apart and the piston rings were seized to the piston and the piston clips were melted to the piston. Dont buy cheap stuff
Wiseco hands down! No other pistons out there comes close to there product.
The only quad i likes was the Zilla.
I jumped when you popped up with the mask
It's the internet there's always going to be haters
Shit I've been making my own gaskets sense I was 15 from a roll ive never never had any problems but to each there own just not the top one
How many hours were on it before you rebuilt it?
I just like the forged Wiseco pistons so much more. I'm staying away from cast pistons.
I put a wiseco piston in my IT250. I had to drill two oil holes to cool the exhaust bridge.
I've heard of people cold seizing their new pistons or just locking them up because they overlook these much needed holes fir 2-strokes with exhaust bridges. Cast pistons don't need them just the forged pistons expand more but I'm sure you know that.
Notice how there is no steel sleeve in the jug it's all aluminum. There is no steel insert sleeve.
did this ranger have alot of hours on it?
Optimus quality, say no to drugs...
Jcc is a Taiwanese casting company. Appears to be a legit company.
Only difference between the gaskets your using is the price Polaris gasket are made in Japan so that's the only difference .
So is the cheap one ok
I also use mobile 1 European car formula
wiseco is forged, other is cast
Wiseco piston is wayyyy stronger.
Need a new video on the dirt bike please
It's coming soon; the YZ450F project got put in hold for the Ranger because it's so big and couldn't be moved out of the way
@@MichaelSabo thank u for the reply and I still like what u doing to the ranger!
@@krimzyg971 no problem dude, thank you for watching man 👊
You don't have a $25 digital scale....?!?!

I’ve raced dirt bikes my whole life, I found out if you going to replace something. Go ahead and spend the extra money.
You should take it for a ride
Sold I'm buying me some cheap Chinese pistons
you know hes a metalhead when you said mega grey
Take it for a ride
Hey can i get another MS sticker from you again please? Have a different quad now..02 Honda Trx 400 ...ill post some pics to Instagram soon
Take it out 4 a ride
Lose the wire nuts and do it right.
Rip it mike
You should definitely get rid of the house wiring b*******... soon as I saw that I was very disappointed. Up until that point it was good video. House wiring and Automotive wiring never work together ever.
You should keep it
Weisco isnt the best either buy pro x, vertex or oem which is practically what pro x is
You should take it out for a rip before you get sell it
😂😂😂😂😂😂😂😂
Rip it then sell it
Taiwan machining is superior to Chinese.
