Fantastic Vids. Love the walk through of the upgrades and setting expectations. This info will be super helpful if you're building on a budget; knowing when to buy what parts in what order. Keep up the great work!
This is 100% the way to make a mini petrol head. Once you understand the basics on a small engine the sky’s the limit. Your way of making videos and teaching are second to none.
I have watched endless videos on Governor removal and no one has talked about replacing the flywheel and other parts to do so safely. Thank you so much for this video.
About a year ago I bought my first used monster Moto (just a roller) put a brand new 224 predator, with the help of your videos I did away with governor completely, put real mikuni carb and performance exhaust, I stretched the bike 6 in and others things like steering damper and a nice chain tensioner. Now I'm ready to go billet rod, flywheel and some headwork and let's not forget a cam. I'm not exactly sure how far I want to go with valves and cam size but with your videos I've got all the info I need. You've been a big help and thanks for your outstanding work and videos.
Some of the best how to camera work I've seen. The editing and narration is also top notch. This is like the gold standard guys I hope you're very proud of your work! I'm loving this series!!!
I just want to tell you i 'preciate you making these videos in such detail. I am not an engine guy at all, i am a computer and electronics guy, i can code and solder synthesizers. But now i want a mud motor for my boat, and this series actually has me feeling like i could get it done. Cheers bud!
You could try an offset key to set the advance back before adding the cam and carb. I think you are right and the advance doesn't play well with the current configuration. Also can check non advanced and advanced after carb/cam upgrade.
I’m loving this this is cool to see the type of stuff a small engines. Get to see it with a 4 6 8 cylinder car motors but never with lawnmowers. I like this a lot.
Thanks for the work you are doing for all of us. You have just kicked the tech content of your channel up to the next level. Your dyno results with the cam have convinced me to stick with the stock cam on my off-road build where low speed torque will be more useful than max HP at high RPM. I can hardly wait for the 440 series of tests.
The timing advance makes more sense along with the performance cam. I wonder what would happen if you pulled some timing out with this exact setup, I'd bet you get some torque back down low.
This is the best small engine/go kart mini bike site on the web. This series passes on REAL knowledge that can be acted upon. Thanks for the great videos and great camera work/editing. It give me confidence (maybe false confidence) to act upon the information I see here. Thanks so much. Now what I really need is a way to upgrade my engine AND have electric starter….. I don’t think there is a billet flywheel with the starter teeth is there?
im enjoying the real-world test and tune series with dyno results, I was not expecting the dyno results because it seemed to be a ton quicker, I was assuming it made a bit more power not just moved the power around in the rpm range.
Great data & video Greg! Yes, a UEGO (Universal Exhaust Gas Oxygen) wideband from now on. This will answer questions I've had for years about whether air-cooled gasoline engines should be run richer than water-cooled (to keep it from overheating the air-cooled eng.), OR just the same AFR as water-cooled. Greg, please include a CHT (cylinder head temp) thermocouple (spark plug ring type is fine) also.Get spares, they are delicate. This will help see effects of AFR changes on CHT & detonation threshold. 👍😎
Thanks for all your great content in 2022 Guys! Happy New Year and all the best from me, an English Guy living in France. Rich. Take good care of yourselves X
Great segment. Engine masters small engine edition. 😊. I haven’t watched your videos in a couple years. I’m sorry. But now that I’m back you’ve done a fantastic job with this RUclips channel. I remember you leaving your job for this. Good job Greg.
You can adjust the timing about 3-4 degrees with offset flywheel keys. If one is available in that size.I was lucky one time because my crank had the same key as the camshaft from a Mercedes diesel. Mercedes sells those offset keys for high mileage engines with worn timing chains.
Hope you and you family had a wonderful Christmas and hopefully the new years brings you all that you wish . Thanks for all the great videos and hard work you have provided so many with awesome entertainment huge , huge thank you
How about adding a supplement video for each episode. Details about tools needed, products installed and fuel/lubricants used. I know a lot of people are new to small engines. Details mentioned previously in an episode supplemental video would be appreciated by many. Thanks for taking the time produce these videos. You are providing a service needed by DIY people. 😃
Thank you again for another great year of videos.Your builds and play always entertain and teach us.I hope the New Year sees your family safe and happy still,and that we may continue to enjoy watching your videos.Happy Trails to all who view.
Red beard is the best I love a lot of focus on safety helmets when riding like you were and scared of flywheel exploding don't blame you thanks for telling youngsters awesome series
@@RedBeardsGarage An idea... a 3 cylinder radial engine using 3 250cc cylinders, bores/heads/rods... and for cooling use a beetle fan/shroud oh and fit to a shortened beetle and g/box.... ?

true, but these type engines do have a lower rpm speed limit too if you want them to last a little while. maximizing torque+horses under 5K may be the better goal, along with starting its power band at lower rpm's too. no intent to troll with that, these splash oil types are what they are.
First off love the channel, keep up the great work. I do a lot of garden tractor pulling. I see your getting a good bit of after market parts which is great news. I'd be really cautious with turning those kind of rpms with a stock cast crankshaft. that's the heart beat of the motor. and when it goes, it takes out everything inside your motor. You may want to get your rotating assy balanced. That will definitely help with harmonic vibration in which is a crank shaft killer from high rpms.
Redbeard your one hell of a good mechanic,you explain shit spot on,ive learned alot from your vids,your only small engine builder i watch,bless yah,be safe
An interesting series, that I'm gonna follow all the way through! Thank you for putting in the work and being so informative. If your near western North Carolina I'd love to meet you and work with you, see I'm also a red beard and love working in the garage
@@RedBeardsGarage I feel like this series show us how much gain we are getting from what parts we are getting I can't wait until you put the non hemi Head on the hemi block I want to do that to my engine but I don't know about the roller rockers and push rod length cause of the head being milled I may have to go with the non hemi Head and not have it milled do you build engines for people if they were to pay for it upfront
Bro. I can’t say thank you enough. I have been waiting. To get the juggernaut for about five months now in this video made me go and look to see if they were in stock. I have never ordered something faster.
When setting the timing, does it make much difference to offset the timing at all? adding timing or taking away timing will there be an increase of torque and hp or just one and not the other? love the content yall produce keep it up.
I'm wondering the same, I took off governer and replaced the flywheel , new one has advanced time, now my bike isn't as "quick".. like it's not as torque-y as it used to be.. and seems to be a little sluggish off the start, not sure if I messed something up or if it's just the advanced timing on the billet flywheel
I highly recommend when doing this to get a vm22 carburetor at the minimum. Ditch having an annoying spring throttle cable setup and attaches directly into the carburetor. More performance, easier, cheaper.
Good videos , I noticed on the dyno that he drive chain looks very loose because it flying around so much . Could a bigger chain a little tighter help .
So the next video should be, the mikuni on a gov delete then like a thinner head gasket then port and polish before we ever get into talking a cam. Be interesting to see what head work will really do. Thinner head gasket should make alot of power honestly
Awesome video everyone! We just removed the governor on our new 224 engine and are waiting to upgrade the rod and flywheel before we fire it up too! We also swapped the cam and valve springs for maximum effort 👌
You mixed the Dyno results up at 14:30. You can see just by looking at the rpm plus you even showed the deleted chart right before the clip of both then you labeled the deleted chart as just stage 1. Did no one else catch this?
Cool series! I noticed that you didn't adjust the valve lash. Is that because you didn't change the cam, so the stock settings "should" be fine, or was that just an oversight? Thanks for what you do!
Spot on about the ignition timing moving your powerband. Can we all take a moment to give the stock connecting rod a round of applause?? It was revving into the 6K territory and held! Very impressive. I'd also love to see a spark plug shootout. I am NOT a fan of the Torch Chinesium plugs....I put an NGK BPR6ES-11 in my Hemi and I swear to the Almighty it started and idled easier, ran crisper, and felt overall better. NGK goes in every engine I own :D Curious to see if minor gains can be found in plug type/gap.
Really enjoy your channel and videos! Quick question…I just replaced 6.5 hp with a 7.5 hp side shaft on my sons Hammerhead. The Series 30 clutch converter is too small inner diameter to fit on the new shaft. The old one is 3/4 and online recommends going to a 1 inch, but that seems too big. Do you have any idea which size would work for us? Thanks.
Greg dont forget that its not just peak hp and torque. Area under the curve makes a huge difference The amount of the rev range that is increased makes a bigger gain than a peak hp that is felt at the top of the rev range I could not see ( not sure that the scale is the same between the two results or im just blind) that there was more power under the curve in the later pull. Great series !!
It’s s harder to make horsepower in the higher rpm bands. But the fact you had real world gains in max speed, how much time saved getting the bike to 30 and 40 indicates better. This is such a great upgrade as is. HP may need to be compared side by side with same timing on flywheels. It just changes things so much with the advanced timing.
I had a magnet come off a stage 1 motor but heavy cart and steep hill got the rpm to who knows? Broke the magneto off the block and went through the sheet metal cover, convinced me I'd want a flywheel if I was going to turn it up!
Just got a brand new 212 Hemi for cheap, did some tricks to it, stock rod, stock cam, switched the head over to a non hemi head. Got it spinning to 5700 rpm. Has about a solid 4 hours and it’s great.
Curious if you recorded the stock ignition timing versus after the flywheel change? Seems to me that not knowing and being able to adjust the timing, would be leaving a lot on the table. Disclaimer here, I don’t know sh*t about these engines, so I may be missing something.
I believe the billet flywheel is also heavier than the original that is going to reduce power. Rotating mass is a big factor in racing engines, You want to build a racing engine as light as possible but strong enough to stay together. 1lb stationery equals 6 lbs spinning- at the scale it might be ounces but it still makes a huge difference.
Hey Greg, I was curious what you would think a kickback would be from. I recently upgraded to stage 2 212 predator and I’m getting a really hard kickback when trying to start. It worsens when the engine is warm. I’ve rechecked the valve lash multiple times. Just curious what your diagnosis would be?
Hey I have the same problem I just installed stage 2 , top plate, 18 lbs springs , billet flywheel, and removal of governor and Removal of governor gear on crankshalf, I have hard kick back. IM SCARED! Please help
Those stiffer valve springs will also suck up a little power with all else being equal. I understand you need them to be stronger to avoid the potential float issue but everything is a trade-off. It takes power to make power. Not trying to criticize your video at all. I enjoyed it and thank you for sharing. Just saying the stiffer valve springs might be somewhat responsible for you not seeing the power gains you were hoping to here. 🍻
How much is the weight different between the stock and after market flywheel? You running an energy dyno, so just light flywheel will reed higher numbers in because the power goes in the dyno, not spinning up the flywheel
RBG The Road To Horsepower Analytics is great content and explains better the stages. How about adding dollars per stage of upgrade. Also I’m 6’2” 280 lbs. looking for full suspension off road mini bike and ideas?
Great video. Very informative. I have one extra washer that I'm not sure where it goes. Is there a washer between the cam shaft and flywheel side of the inner housing? It's a bit smaller diameter than the washer on the Governor gear.
As a guy who is doing his first engine swap this was extremely helpful if I add a torque converter would that hurt anything or would I need to upgrade other things as well ? I’m happy with just going 40
Excellent series guys. I'm watching intently to see what I could be doing to my Minibike. One question I had concerning the Dyno readings. Do you think the Clutch might also contribute to the weird readings? I don't recognize the clutch that is on the engine when you show the Dyno runs.
I have basically the exact stage swap less the makuni carb to the Nibbi 28mm racing and wheni ram it with my phone on speedo application I hit 52mph. I have a short header and it sounds like a Harley. Can’t really afford togo any further cause someone stole my bike and soled it for 300$ worth of drugs I’ve been told! Probly won’t be able to get another bike for a while cause of the whole Covid and being the only one whitout kids on my crew so I got laid off! Anywho love the channel! My first and only subscription! Be safe
Have you seen the plots of coil gap vs timing? I believe ARC recommends a much larger coil gap than stock. I wonder what difference that would have made?

This is the way it should be done. I wish I had a small engine dyno. Please do this with a Briggs Vanguard 23HP 627cc engine. Thanks!
Have you thought about a chain tensioner for the dyno? That chain was dangerously floppy on the last pull
the flailing/noise can throw readings down some too.

Been a week I really can't wait for the next video
Just found your channel and very much love the content u put there but was wondering if you have or could do a video on how to set up a rpm gauge???
I highly recommend when doing this to get a vm22 carburetor at the minimum. Ditch having an annoying spring throttle cable setup and attaches directly into the carburetor. More performance, easier, cheaper.
I wonder what Stage 5 will bring, maybe fuel injection or forced induction? Cerakote might be necessary for extra cooling in later stages.

What did you do to switch the head to a non hemi I'm thinking about doing the same thing
@@lawrencecoleman7850 you need a hon hemi head ofc, and stock length non hemi pushtubes. The ones I have are 5.34”
Looking at the dyno results, would a valve spring upgrade on the stage 1 pay off? It looked like it might be based on the dyno curve.
Love these dyno tests.keep up the great work
It would be so helpful if you did this slower or more of a how to, step by step, type of video so others can perform the upgrade on their own too.
I’m going to pick up a 224 for my first go-kart build. Can’t wait to modify it like this!
Hey RB! Awesome Series! Could you add Watts to the list of output stats of the dyno? I would like to see that number as well! Thanks!
Curious if you recorded the stock ignition timing versus after the flywheel change?
Seems to me that not knowing and being able to adjust the timing, would be leaving a lot on the table.
Disclaimer here, I don’t know sh*t about these engines, so I may be missing something.
You might try opening the coil gap to 60 thousand for more performance.
I believe the billet flywheel is also heavier than the original that is going to reduce power. Rotating mass is a big factor in racing engines, You want to build a racing engine as light as possible but strong enough to stay together. 1lb stationery equals 6 lbs spinning- at the scale it might be ounces but it still makes a huge difference.
Love this series 👏👏
That increase in the previous video (state 1) was quite impressive especially considering how minor the mods were.

As a guy who is doing his first engine swap this was extremely helpful if I add a torque converter would that hurt anything or would I need to upgrade other things as well ? I’m happy with just going 40
Are you going to use a slide style Mikuni 22-26mm carburetor on future test?
You should only do one change at a time. That way you can tell what difference each change makes.
Excellent series guys. I'm watching intently to see what I could be doing to my Minibike. One question I had concerning the Dyno readings. Do you think the Clutch might also contribute to the weird readings? I don't recognize the clutch that is on the engine when you show the Dyno runs.
Not sure if you can get the chain any tighter in both videos it looks like it is really loose
Can’t wait to see the next one
can you do a dyno run with a torque converter in place? It would be interesting to see the curves. I like this series. So cool to see actual numbers.
I have basically the exact stage swap less the makuni carb to the Nibbi 28mm racing and wheni ram it with my phone on speedo application I hit 52mph. I have a short header and it sounds like a Harley. Can’t really afford togo any further cause someone stole my bike and soled it for 300$ worth of drugs I’ve been told! Probly won’t be able to get another bike for a while cause of the whole Covid and being the only one whitout kids on my crew so I got laid off! Anywho love the channel! My first and only subscription! Be safe

What ever happened to the full suspension Shredder motor Mega Moto 212?
If its possible, move the timing back to stock and see what happens, the billet flywheel is so much lighter it should rev quickly
Yes I can move the flywheel back with a offset key or without a key at all. I will do that in an upcoming video.
@@RedBeardsGaragewhat would you expect if the cam was one tooth out?
Any word or updates about the 459cc performance parts development or parts compatibility with other engines as well as an engine build
Have you seen the plots of coil gap vs timing? I believe ARC recommends a much larger coil gap than stock. I wonder what difference that would have made?
What happened to the 200cc Lifan build shifter kart??
