Which Piston Should You Be Using In Your Dirt Bike ? Lets Look At Forged Pistons Vs. Cast Pistons !

[@Bean-or1mv]

just put a forged wossner piston in my 2011 kxf 250 and i couldn't be happier with it, first time running wossner and will definitely run them from now on.

[@Greg4bmx]

yo any update on the cerakoted piston you did a while back?

[@Henrik.Yngvesson]

Forged aluminium expands more so that's why you need a little longer warm up as the cylinders are cast and also warms up slower than the piston. Don't know if it also happens on 4 strokes but on 2 strokes you can get cold seize if you run hard without warming up.

I learn a lot more from your videos than I do most other dirt bike related channels on KZbin. The way you explain things is very clear- which is genuinely appreciated. Because the content is both informative and interesting, it always makes for good viewing. Looking forward to the next video.

[@cer7cer7]

@LUNDMX.. Hey there. What did I win? I didn't realize there was a prize...?

[@A2Hobbies]

what ever happen to that 2 stroke piston you cerakoted?????

[@frankscalzo5250]

Waiting for another 2 stroke build, come on Lund. 4 strokes 🥱

[@jcobra09]

When doing a frame up rebuild on my 2007 RM 250, I went with a Wiseco YZ 250 GP piston (same one RC4 ran). My OEM cast piston still looked really good for its age. Just wanted everything fresh and to last. I heat cycled/broke it in as per Wiseco’s instructions to a T.

[@Dodds_Dirtbikes]

We need a two stroke version of this video also! Ive heard all different takes on cast vs forged for 2 strokes

[@chihuahuaverde425]

Good call.

[@Pumpkineater19]

I’ve got 100+ hours on my forged weisco piston on my 85

[@travisingraham7116]

Thx i did learn. I generally go OEM, BUTT i think my next rebuild im gonna try forged

[@carperrolls1399]

The same go for 2 stroke pistons?

[@JR-ut1yx]

For my yz125 it's oem.

[@ainnotv3241]

Love ur channel bro!! Blessings 🙏🏿

[@billhardaway6222]

Awesome Clint. Thanks for the infor.🏁💯🏍️👍

[@inton2llc347]

very good insight! I just placed an order for a Wossner, my yz450 has 72 hours on it and I can tell the piston isn't healthy! thanks for the info!

[@timothysaylor6835]

What do u think of namura pistons

[@Digitaltiger123]

Had a friend who did 50,000km on original piston on a 04,only rings and pin changed every 4-5k and not always,a forged will never last that much

[@shotgunbrown2821]

Wheres Adam at this year kenny took his ride lol

[@Dissentient01]

It is not hard to explain. My '06 crf450r rips stands in 5th at will. My fuelie kxf? Not so much.

[@krudlumpstv7854]

Bro I can’t even get through a whole video of yours with ought looking for bikes for sale on Facebook 😂🔥

[@andyjonson9760]

Wössner makes really high quality stuff.

[@bryanmoorhead4615]

Kinda bummed that waossner doesn't make a wrist pin bering to complete the top end rebuild kit. Unless I missed it on their website.

[@OtisFlint]

This is exactly why the best pistons are now 3d printed. You can't mill the most efficient bridge box designs. We've got 3d printed pistons running 1400hp in 6cyl applications and no problems, while 10% lighter than forged.

[@Hanky_Bannist8r]

I have a noob question. Regardless of brand, in a hypothetical case of failure wouldn't a forged Piston damage a cylinder far worse than a cast ? I may be rebuilding my Cr250 soon.

[@Daniel456324]

No, you would experience scoring of the cylinder walls if you didn't properly warm the bike up prior to riding. With a cast, you just start up and go, but with forged it expands more rapidly.

[@DIRTBIKEFAB]

Just another good topic you could touch point on is 2 stroke cast/forged pistons with steel sleeve cylinders vs nikasil cylinder. But for be it’s forged wisco. Just my flavor of pizza.

[@dirtsquadatv2714]

If you heat up those crushed washers with a torch then set them in a piece of steel they'll bounce back to there shape.

[@theexisting1514]

Bike came out clean!!

[@loadtoad714]

Mad respect for throwing Liver King lol. Roid rage!!!!

[@davevaughn7057]

Do you change the cylinder when you put a new piston or do you check the cylinder first to make sure it’s not egg shaped

[@chihuahuaverde425]

Thanks Wossner!

[@philthy63612345]

Boring 4 stroke problems! Haha joking. Love to heard your thoughts on pistons for 2 smokers

[@mikelawrence4041]

I thought my screen was dirty but it was dirt on your lens

[@ryanphillips3916]

Buy a heater!! 😂😂😂

[@typ2vw159]

Pissed~On I mean wistco never …stock if you are not a pro. An LA Sleeve.

[@dirttricksusa7857]

hell yea!!

[@justinlacasse7141]

You said "piston" right on the first attempt in French.

[@augieh6146]

Around 6:07 Man I must be a spoiled new age kid. I mean it when I say I don’t like carbed 4 strokes. I really do not like them at all. I’m spoiled, and not important that I know of hopefully not too many get offended lol.

[@hachtenduro7824]

Injected has more potential than a carb can ever have. - but the potential is often not fully used by the manufacturer, as very many signals from the sensors have to be computed and inputs for ignition and injection have to be generated in precise manner. Here lies the beauty of carbs. They have a certain behaviour that is hard to mimic by an injection system. And that is a nice feature, it makes the motorcycle feel like a living organism rather than a computer on wheels. This may not increase your laptime, but can contribute to the joy of riding.

[@augieh6146]

@@hachtenduro7824 hmmmmmm. Would that mean you can get more out of an engine with a perfectly tuned carb? Rather than efi. Or efi can be made better? Maybe carb tuning is easier than efi tuning??

[@dirtboy896]

Forged wiseco pistons run like poopoo. Always had better luck with OEM and Vertex.

[@travismccloskey9733]

"No purchase necessary" Just buy parts, simple. Lol

[@jonnoMoto]

The problems with cast pistons are what you state, user error. They get used way past where they should, slapping about in the bore, and guess what, they shatter. Big surprise. Personally I'm happy with cast. When I was slower I'd change at 150hrs, but now I won't go past 50hrs. I've had engine failures but never a piston failure. I do have one forged but it's because it was the only type for a bigbore hi comp setup.

[@augieh6146]

Just no numura lol

[@dennismillus4581]

Cast arecway more reliable.

[@surfrbrian]

Freaking Frenchies!

[@woodballfreak]

First comment let's go 😂

[@BandManCover]

The OEM Honda Rods are Forged. All the pistons you shown are all forged pistons, including the OEM Honda Pistons. None of the pistons you shown were cast.

[@motozz8258]

10hrs aha thats a joke surely , insulting your viewers
