Stroker Kits Explained

[@jamesgravel7755]

Been building engines for 30 years and nothing in this video was nonsense. If you guys need to watch this video a couple times. Do it and learn the proper procedure because this is all true for any engine. It’s nice to see the small engine game is getting so big They make it so easy to grab the right parts now with very little guess work.

[@krudlumpstv7854]

I’ve learned so much from these engine building videos that you’ve been making over the years and it makes the minibike hobby so much more enjoyable to know all the information you share 👍👍

[@bbaaspencer1]

I’m an automotive mechanic and Been watching RBG since he started his first video. I learned some pretty good tips from him. He upped his game by getting a dyno! You can see the horsepower gains when he does an upgrade.

[@Bull3tBikes]

I was recently given a 1996 Dodge Viper go kart to restore, it was a dealership promotion from when my late uncle bought his Viper back in the day, i plan on replacing the brakes & tires first then the anemic nearly 30 year old Honda GX100 engine with a brand new 196 with a 204 stroker kit, intake, exhaust, springs and mild cam.

[@shotbyzaystudio]

this video is underrated you give all the info in short time, straight to the point.

[@ianellithorpe5918]

Absolutely packed full of lots of valuable information. God bless RBG!

[@RedBeardsGarage]

Thank you for watching!

[@ianellithorpe5918]

Thank you for what you do and more importantly who you represent!

[@RealDGoodwin]

This video is the most informative for folks that want to get serious about their engine builds, Red Beard keep up the good work sir. God Bless!

[@Greybuiltracing]

Great info ! Ec is pretty much on top of their game . Their website is full of info ! They have pages and pages of how to and specs . I’m using their 236 stroker kit and it rips !! I think I’m gonna do a video on it pretty soon and send it .

[@kartnerds]

The level of this video is wow. Dudes got a subject and stays in the direction. Ez to follow along, and the illustrations and edits makenstuff like the connecting rod measurements almost feel tangible. Excellent video. Thanks for the effort.

[@irepairofpc31familykartrac51]

Good job of explaining all this. The graphs and pics were very useful thanks.

[@rcclassiccrawlers4368]

Very detailed explanation. Excellent video!

[@turkeyboyjh1]

Just got my self a new 224 predator a few days ago from my mini Baja I’ve had for a while now I did as much as I could on a 0$ budget with the 196cc I ported, sanded the block, deleted the and head the one thing I bought was a thin head gasket, jetted the carb and ran 5:1 gears with a clutch and got 48 mph, I’m still waiting on the torque converter and I’m going to see what the 224 does stock with an exhaust and torque converter does then it’s billet rod cam valve springs flat top piston flywheel and slide carb time

[@JohnFrolick]

By far, your best video.

[@christiannagy8417]

My opinion on stroker cranks is that they defently produce more torque in the low end but you also increase the wear on the piston (increase in the rod angle = more forces on the cylinder wall = more friction and heat) so when you ride the engine on the race track and you are on crazy rpms you could overheat it or worst case cenario you lock it.. overall i would ride it just in something you need a lot of torque and max at 6500rpm (throttle stop or sm).. piston acceleration is also higher, so you got even more friction! Btw great video! Always learning something

[@DeezGarage]

Shorter comp height piston+ long rod 😎= rod ratio

[@christiannagy8417]

@@DeezGarage yeah that's right, but did he install a shorter piston and a longer rod? I'm honestly not good in calculating in inch bc i'm from Austria.. btw i'm also watching driving4answers Videos and stuff about Balance, rotat'n assembly geometry and more.. he teaches it very understandfull 🤙

[@johnmattinson3513]

I’m excited for the Ghost build! I’ve had one for little over year now and I’m ready to build it.

[@NubsWithGuns]

They aren't anything that special. Just looks pretty enough on the outside for HF to fool all the sheep. Not garbage but isn't some holy grail OMG engine.

[@johnmattinson3513]

@@NubsWithGuns thanks for that clarification, I’ve completely changed my views and opinions on the Ghost engine now. Thanks

[@NubsWithGuns]

[@markyoung9964]

Wow! This is what we've been waiting for. You've separated from the crowd!

[@Rad.Dad.Customs]

I have several of most of the ones you listed and have sold some of them all in one way or another and I'm still old school and my favorite will always be my 5 horse flatheads😂.. Build on guys and girls!

[@deltacx1059]

A better ignition is helpful too.

[@anan0moose]

Paul Reubens was the most famous stroker that I am aware of.

[@kevins1242]

Good ol Pee Wee

[@davidowen888]

Great teaching Professor Redbeard 🤓👍☮️

[@RedBeardsGarage]

Thanks for watching!

[@justinwatts6210]

remember everyone with big enough valves and a fast enough piston you can actually pull in more air than the displacement essentially making a small amount of boost at high rpm

[@philroe2363]

Best RBG video ever!!!

[@8822fitzy]

My wild cat is knocking. Time for a rebuild! Thanks for the video

[@RedBeardsGarage]

You bet!

[@jondavidmcnabb]

Excellent video and tons of solid technical knowledge. Thank you for posting this.

[@CR4ZYxRY4N]

I wanna build one of these 224 for paramotoring at below the 1000$ range

[@johnkoelliker8480]

Awesome explanation

[@josephstoots6548]

Any idea when EC is going to start selling the forged 72mm pistons? I don't see it on their website. Thanks.

[@OGTtom]

Another great video , thanks Greg .

[@RedBeardsGarage]

Thanks for watching!

[@Deucealive75]

In 2009 the Greyhounds were $99. I got three of them back then. With a 20% off coupon plus tax they were $88 a piece. All still run well and one of them is on one of my Colemans.

[@RedBeardsGarage]

I came in the game too late for them. Predator was everything when I came on the scene.

[@Deucealive75]

@@RedBeardsGarage The Greyhounds are ok. Unique block because of the tank mounts and side cover. The head took a rocker cover that used 5 bolts. They called it a 5 bolt head. Everything else clone.

[@calebtaylor5154]

A cool comparison to see is a 110 pit bike vs one of your mini bikes

[@nessie42786]

Been at it for a while. I have 1 champion and 2 greyhounds. Sell them cheap. Stack them deep.

[@georgehunter4023]

I don't recall seeing or hearing this in the video but a hypereutectic are much more temperature stable piston choice of all with the extra silicon content. offers you the ability to run a closer fit between cylinder wall and piston skirt. forged and billet pistons are far better for extreme horsepower under high levels of boost but will be noisy oil burners until the engine comes up to temperature and also forged an billet pistons can be a risk for cold engine seizure if you do not thoroughly warm up your race engine before giving it "The Beans!!"

[@cedhome7945]

Great video. If you have worked in the motor trade the dumb ass questions your have to respond to make you wonder if we are all the same species sometimes. So this is just the information people need plain and simple, if you are deep into an engine then this is exactly what you need to know. 👍🇬🇧🇺🇲

[@6speedguy845]

Interesting information

[@rustyshakelford4232]

Hey bud. My 13YO son and I are wanting to put a Kubota D722 in his offroad buggy. He had one given to him out of a commercial zero turn, as payment for him repairing a Scag walk behind. He's REALLY excited. We found your build series on the one you did, but you never finished the series. Any plans to release the rest? Thank you for the great content.

[@mattjonesturbo1]

Best thing for a stroker is the Dyno Cams 224 camshafts there already clearance in between the lobes and the lobes are narrowed for clearance plus have a slimmer compression release for the 58mm crankshafts. Cheers

[@ganzonomy]

Can we see a stroker kit for the road to power engine? Or maybe a legit Honda built?

[@MannyBeInvesting]

So if I buy this exact engine model the measurements in this video are good for me to report on or is each engine unique and I should measure myself?

[@zachlynn276]

Glad to see this video was just thinking about this

[@BradFFA]

Hey can you tell me the height and width of the 301 pred I’m wanting to put on my doodle bug and harbor freight doesn’t put the right info. Because on the website it’s showing the 224cc being taller maybe wider then the 212cc and everyone’s saying there the same. So I’m not believing there size specs. Please respond with some info thank you.

[@ethansecrest8374]

Just started out in this hobby been watching rbg and getting a good idea of building but I have a quick question if you do a stroker kit on a hemi will you still be able to head swap down the line ?

[@BadmanMC407]

Appreciate you big homie

[@kylehickmon]

Why is my predator 212 non-hemi puffing out blue smoke?😢😢

[@markyoung9964]

blue smoke is oil smoke-that's the starting point

[@rdallas81]

Rings or valve seals/valves

[@keen1957]

Wowzer! Good vid!

[@koreywilliams4570]

I need a pipe bender. And a couple other things. I'm ready to start my next mini chopper build

[@SportbikerNZ]

Don't forget to start the 1st one before starting the next one.

[@SNELLERIZED]

My only complaint with EC is their 20% restocking fee, should you order the wrong part.

[@ruicunha103]

you can assemble the engine with 0 deck height? piston will not hit valves?

[@hackerwho1159]

Could I put this kit on my non hemi predator

[@Marshrat3006]

Is there a stroker kit for the predator 670?

[@WalkerSmallEnginePerformance]

Good point on the balance. I never thought about the lateral forces from the counterweight.

[@Benjamin-xv2hg]

So I've done all this work really dialing in the engine but carburetors are still black magic to me. How do I know what size I need or jetting. Is there math or something to get me into the ballpark and then I can adjust from there?

[@davidwillis5016]

[@GrantOakes]

Any chance there's going to be an aftermarket stroker kit for the Predator 670cc V-Twin?

[@SportbikerNZ]

The 670 is already set up mainly for torque.

He's already done that.
