Tearing My 100hp Banshee Engine Apart... (WHAT HAPPENED?)

[@joeypooschke7914]

521 for sure!!…John’s 521 vs sabo’s 4mill quad wars??? I see this in the future..

[@johntodd4740]

521 build would be insane would love to see that up against mikes 250r and your quadzilla once it’s done

[@jimmykingjr2692]

Lovin how john does this teardown! Using tools that he already has..nothing special..just like 98% of us would..no fancy,expensive tools..just the basics.

[@matthewm3965]

That's super cool how the banshee case splits apart dude

[@treeassassin]

Buyer for that front end raises hand! (If you are selling). Loving quad wars. I just want to see this rocking that one wheel action you pulled on Mike's... Liked, shared keeping that algorithm going.

[@gollxy3457]

The banshee videos are lit

[@wtscheel1]

Leave the clutch pack in before you remove the center clutch nut. Press the pack with left thumb, impact gun in the right.

[@Zalagar619]

I personally want to build mine into a 421 Serval. If it was me I'd keep the 472 and build it back to good running condition, then make 100% that it's dialed in correctly and running the correct mixture to keep it cool. Maybe even have it dyno tuned to where it has all the awesome power, but a hair on the rich side for prolonged life :) I personally could never use the full power of a 521 where I ride, or even a 472 for that matter. They are fun and all but the bigger you go, the harder it will be to keep it cool and your gonna have to extend the swingarm even further to keep the front end down. That's just my 2 cents, but do whatever feels right for you and your application. Keep it up man!

[@Punny1234]

Great video that was clear and concise, it was very much a tutorial for me.

[@logansnyder7701]

Great Job John. Can't wait. The Quality of Videos are Top Notch. 👍👍

[@williamheidbrink2411]

Little advice drill small holes in your clutch basket so the fluid gets to your plates better

[@minnowlaketuning]

521 brotha let's go haha. Sucks you need to re nick but then maybe this will be a good reason to go with the 521. I'm sure there you could sell that block anyways needing the 1 cylinder re nicked, they arnt too cheap so someone may buy it an re nick it. Nice progress keep at er

[@quadbrothers5801]

i always thought one pipe had more smoke then the other in the quad wars series.

[@andrewstahl6916]

watching you pull apart this engine really makes you realize how simple some of these old 2 stroke motors really are. This engine was basically used by something from yamaha from I think 1973-2012 (yamaha rd350 - banshee's final year in production) The engine that they brought over from the street bike to the banshee is basically the same exact thing, which is why I said that.

[@StupidFastJohn]

Yessir, the history is my favorite part! The power and amazingness is second 😉👊

[@andrewstahl6916]

@@AmateurHourProdu I dont think you would be able to, I know the engines are basically the exact same from the (rd/rz/yfz) 350, maybe you could but I wouldnt know, and I dont know if theres anybody out there that has tried

[@StupidFastJohn]

Its been done before and some of the aftermarket cheetah setups have a powervalve as well

[@andrewstahl6916]

@@StupidFastJohn you learn something new everyday! I never even knew that they did that with the cheetah's

Definitely a 521 love the vids man going riding tomorrow

[@StupidFastJohn]

Tear it up!!!

[@royhenson3379]

This is Outstanding work.. Amazing video. You really edited everything perfect..

[@mitchq280]

Power is great but definitely have to get that banshee to handle better some shocks and arms would do wonders

[@keithparady2594]

Good stuff man

[@THEDUKELOVER]

could you cut the exhaust ports out maybe port and polish job should help get that hot exhaust out faster

[@willbianco8931]

Yeah man so happy to see love for the banshees dude riding Mike's probably got the itch to run her again do thankful for the update be well my friend

John you just love those prison sandals lol

[@ericfix0521]

I found this channel through Mike Sabo but honestly, i like yours a small bit more. His is sweet and you guys are both awesome but im a stupid fast guy when it comes down to it

[@rubenechezabal6397]

521 all the way... more cc = more power!

[@zackparker952]

Put that 521 on there big dog

[@ttatvoffroad2632]

How many times would Mike Sabo in this video have said thats what she said?

[@StupidFastJohn]

🤣😭

[@DavidJohnson-ri2on]

I made my own clutch tool. I welded a busted screw driver to an old steel plate.

[@StupidFastJohn]

Thats a good one! 👊

[@zackparker952]

A whole new fresh build

[@outinthebackyard7579]

521 would make a fun quad warz series but I definitely get it if you want to fix what you have.

[@dennisbrooks186]

Deff 521, sucks u wouldn't be able to use that supercub cylinder for the 521 anyways. Have to get 10mm/72mm cylinder setup for proper deck height and port timing. But jump on h.q. on f.b. and there's always someone that has a setup ready to go. Find a machinist to trench your cases and u deff want the cases port matched and bored. Would be a sick build. I run a 521 so id love to see a 521 build video!!!

[@just_in_time5518]

I bought a RM125 that had a piston that looked like that when i tore it down. And it still ran! lol

[@StupidFastJohn]

2 strokes are amazing machines bro 👊

[@wtscheel1]

Pto side crank seal was installed backwards.

[@reggiexp69]

i love how easy banshee are... to fix. but also very easy to break LOL

[@keithstone4476]

What do I want to see? Trike wars, 250r's, 350x's, 200x's, tecate's, tri-z's. Would also like to see hybrid builds such as a banshee engine in a trx450r (just the first idea that came to mind)

[@hepworth1086]

Yes go the 521. I have a 421 and no one has done the 521 in Australia so would love to watch it before I do the setup in mine

[@StupidFastJohn]

I know a guy in germany who did 👊

[@hepworth1086]

@@StupidFastJohn I will have to have a look. It's really expensive to do the banshee here. I have spent 25k restoring mine and building the 421. That's with me doing all the work so I'm a little scared to spend the money without knowing 100% it's what I want. You and sabo show all the details in builds and results and I trust you both so a 521 build video would be awesome. Plus who doesn't love 2 stroke content 😊

[@lukecombs5242]

Please change the mucus color on the frame bro lol it doesn’t work with the boring blue for me badass banshee though I loved the early to mid 90s purple and yellow banshee I think they made two different color schemes like 94-95 correct me if I wrong those were my favorite color schemes for the banshees. But I’m excited to see where this build is going 🤙🏻🤙🏻

[@victorgirouard1543]

Ouch crappy deal what can you do live and learn. Maybe try to run it alittel extra rich next time. Plugs are cheaper then pistons atleast. Good to see you doing all the wrenching yourself. Keep up the good work man in will be even meaner after this rebuild for sure!

[@vexygg7622]

Raptor 350 vs warrior 350?

[@respinosa2314]

mini quads for the next quad warz

[@ethanprice1252]

The 472 was an animal...but now it’s time to see what the 521 can do

[@goldenwheeledbanshee9160]

You build it the way you want it John. I'm sure you'll put some power, in it. U, need a reliable and fast Banshee.

[@StupidFastJohn]

Barry, words of a wise man as always brother! Thanks 👊🙌

[@lt-z-quadnation6644]

Are you gunna do some one wheeled wheelies on it when you get her running just like Mike’s bike? I think the viewers loved the first one for sure. I will say you certainly didn’t run out of talent that day.😉😃

[@jonnyretro2235]

What is your squish on that motor John?

[@StupidFastJohn]

.050"

[@quadvloggs6876]

Idk how much a banshee cylinder is or if there separate or come in pairs but to re nickasil a cylinder here in Canada is like 300 bucks should be cheaper in the US but im not sure on pricing I didnt think 300 was to bad as like my cr125 cylinder brand new in the box is like 450 bucks

[@StupidFastJohn]

Wow, over 600 to nikasil both last time with "welding" each side 👊 maybe cheaper elsewhere though! And it will def need to be welded this time 😅😅😅

[@johnwright6262]

For quad wars raptor 660 vs 700 I wanna see it

[@15nicojr]

Hell ya 521 for sure

[@kellypoje284]

John we’re should I buy parts for my 86 lt 250r

[@StupidFastJohn]

Depends what your looking for? Oem i use rocky mountain for new, ebay for used. Aftermarket many companies, bp racing, drw performance, and rocky mountain too. Those are my quick go to's! 👊🤙🙌

[@moparman44069]

This is why you leak test your 2stroke motors and youheat cycle them and tune your carbs instead of throw it in and go

[@StupidFastJohn]

This is why you watch the whole series to see the work performed prior to this one video rather then assuming in your own head nothing was done 🤷‍♂️🤦‍♂️

[@wtscheel1]

Right side piston has detonation around the entire piston

[@billymazure258]

I contacted Arthur windford at biggles offroad he can make you a titanium idling gear that will withstanf a more than stock.

nice

[@chuckfrisoli1170]

It would be cheaper to get that cylinder fixed then getting a new one. Take it to powerseal, their prices seem pretty reasonable.

[@reggiexp69]

not in france. i can buy used ones with piston at 64mm or 64.5mm (or something) for 500-600€ while redoing it cost anywhere between 200 a 300€ a cylinder...

a 521 would be cool

I can't believe you took a crowbar to that. Never guys. Silicone or not use a deadbolt hammer so you don't destroy something.

Deadblow? Its really not as bad as it seems. Ive got years of finessing under my belt lol

@@StupidFastJohn you may. The guy who watches then and then decides to tear his apart may not. Pry bars of any kind on cast is a nogo

Get rid of that lockup clutch you will always have metal in your oil also run red line shockproof oil transmission fluid type f isn't good enough

[@williamheidbrink2411]

Could of been an air leak because that would make it run lean fast and hurt your motor

[@StupidFastJohn]

True that, plugs are black and one of the ceramics actually is gone inside the tip and the gap closed. All symptoms of detonation and too much heat. This motor was leak down tested but also the stator side crank bearing is bad too!
