Im building a 301cc for the first time and THIS is one of the only and most helpful videos ive found.your channel has help guide me threw any hiccups so thank you👍🏾
I like the fact that you go into pretty good detail in what you're doing, helpful when someone like me who's still just starting to build and upgrade engines and go karts. Have a buggy i just picked up and putting a 420 on it so Thanks even if this video is 3yrs old.
Well, I just picked up my own engine, and enjoyed having "foresight" in removing those items, and cleaning things up. Thanks much, I chose this engine because of you and several other people who have enjoyed putting them into shape. I look forward to "test driving" mine. I'm impressed with the cleanliness, good design, and quality you show is in these engines. Thanks again.
@@jeremyshea8055 I'd been looking for a carb for a chipper/shredder, two years, and bought the engine, then found a "Chinese carb", got my shredder running, and now am looking at that engine for a "walk behind tractor", and knowing the options from someone else's experience is a great boon. I live on sixty acres, and am planning on planting some five to ten acres next year. This and other videos has opened my options, and made getting going much easier, cost effective. I've found the Chinese have essentially produced parts for everything we've got that breaks, and they work, my government may hate them, but I've always respected their culture, history, and am enjoying their trade benefits.
That gas tank is slick..I will be contacting him to get one made for my racing mower build! Thanks for the great videos, really does help out for people that are mechanically inclined but have never worked on these small engines.. I've learned a lot from this channel for sure!
Can someone PLEASE tell me how to get in touch with the guy who makes those gas tanks ? I have a totally restored Yerf Dog two seater with a new 420 Predator engine and I want to switch out my gas tank for for like this one. Please help. Thanks !!
Really Good video. Prompted me to get in touch with Brad Hill and get one of his beautiful gas diamond plate tanks for my kart. Coming this week. got my brand new (still in the box) predator 420, header, air filter and new 40 series torque converter. Can't wait for this weekend to get to work. One thing on your video made me a little nervous. Not to be too picky but when removing small parts, (nuts and clamps) with your muffler off, you should stick a rag or something in the manifold opening. Having something fall in that hole is a big OOPS, and something your viewers should be warned of. Great videos coming out of Red Beards Garage. Keep it up pal. Thanks.
Thank you! I picked up a run down go kart for my kids that has a 270. Its beat to hell and i wasnt sure what to do. Your video helped a LOT. Lots of info i didn't know.
Awesome build! The gas tank is a work of art that makes the engine. I would leave the low oil sensor alone. It would be sad to lose the engine because of low oil even though one should constantly keep checking the level.
I have never heard of anyone loosing the engine because of the oil sensor removal. You have to remove it on go karts. When you take curves hard or on a off road go kart it will kill the engine. That is the first thing I do when I get these engines
Not sure if you will read this but when you remove the oil sensor bolt, on the other side there was a black plastic piece with a rubber washer. I used the rubber washer with a bolt and didnt need to tap anything. This was on the 212..
Thanks for your videos. It has made finding parts and installing them really easy. Could you tell me which size and thread bolts & orings that were used in the oil sensor and governor shaft holes?
just have to say I really like how you make your videos. I found you through cars and cameras and you really put the for thought into the videos. keep it up and great job man.
i'm sure you are aware of this but let me remind you if you delete the crank cover gasket for rtv on any type of engine like this you change the crank end play. my experience with predator motors they are on the tight side out of the box. for high rpm/load add an extra gasket for 2 1/2 or more thou end play. just use a dial ind on end of crank and move back and forth for a reading. loose end play will rpm better and won't bind the crank and roller bearings.
great video man ,just got a 420 for my off road kart build. even being a stock moter it has alot of power. I can't wait to see it with mods you put on it .
you should paint the white pvc bend pipe thing on the air filter a chrome blue or something or just black. The engine looks sick family bought a new house to put up for rent and i found a chopper bicycle and a vintage yamaha mx dirtbike with no engine and i recently bought a powerfist 193 cc engine from princess auto ( its the Canadian version of harbor freight ) and the engines are like the predators im thinking about which bike i should restore !! im thinking about the chopper tho
fun fact HLSproparts doesn't ship the carb spacer to Canada I've had the go power sports filter and adaptor sitting waiting well I need to modify the go power sports header anyways just got the intake done the princess auto (Canadian harbor fright) engines come with the spacer and gasket
5 years later i had to change the carb because for somr reason the guy i sent my cart to for welding tore the engine apart had the carb so it was just dumping fuel right through to the ground. i got the carb changed now it only runs on choke so i came back here to make sure i have the spacer orented correctly
Yeah. I'm going in circles trying to find a flywheel with a ring gear that will fit the 212cc. The electric starter kit for the honda gx200 has a different taper, and will only fit the non-hemi predators. I checked out the billet flywheels from ARC, but they don't make them with a ring gear and they cost as much as the engine itself. I'm thinking maybe taking it to a machine shop to have them copy the taper from the old one.
Well the hemi does not have a place to bolt up the starter as well. Thats the reason they don't make an electric start for it. The block was never designed for a electric start.
Actually, this one does. Has a November of '16 build date from what I can see if that means anything. I had read on a lot of forums that folks had to do all kinds of stuff before to make them work. But I was able to install the starter as well as the charging coil with no problem at all. Now it's just that dang flywheel not fitting that's driving me bonkers. BTW, thanks for the response - and the great videos.
Just a heads up for anyone else looking to install electric start: I found a direct bolt on for the hemi predator. yay! Kohler 1702530-s Comes with inner and outer magnets, and original fan and recoil start will go right over it. just have to trim the cover and remove one nub from the back of the fins.
A 212 can do that a 420 can do that a 459 should be able to do that when there is more aftermarket support and a 670 can my favorite motor of theirs is the 420 I been able to hit 93 before but I have a ton of aftermarket parts and a transmission
Well you can get a predator 212 or you can get any predator motor just have to upgrade it to go over seven miles per hour if you're trying to do that stock get 670 but a 212 would be the best option with a stage 5 build on it
Thank You RBG for sharing this video about the 420cc predator engine. And, how too modify it. You gave me some ideas about my future 420cc build; especially the air filter! I should've thought about how to do that!? LOL! Have A Great Weekend!
You should add in your description that you bent the valve rod/s. I’m so glad I stumbled upon your 2 yr later updated video. I’m fortunate you made one. Ty! Great detail in your vids otherwise.
After watching a few of your videos, listening to you talk and seeing your tools, I think Harbor Freight should be a sponsor of you and the channel. You make their tools look good. I have several sets of those screwdrivers ($7.99 on sale) as well as those long pliers. Love Harbor Freight, one of the good things to come out of California. Thanks for the videos.
Hey red beard I have a mini bike with a predator 212cc with aftermarket air filter, exhaust, and I drilled the jet. Every time when I'm riding it will ride good then out of nowhere it starts to die .last week I went fishing with my friend and when I went to get back home I started driving and it died even though the engine wasn't hot and I let it idle for awhile so I have no idea what's wrong. I need your advice
if you leave the low oil shutoff in the engine it will automatically shut down in event of a rollover. just had that happen while drifting my off road garden tractor! LOL!
I am building a mud motor for my duck boat using this same motor...what would you estimate the HP is now after you modded the engine as is in the video?
Ireally like watching your shows, but I have a question. What will happen if you don't take the governor completely out of the engine rather than just disconnecting the linkage and hooking the throttle cable right to the carb?
I haven't run across any of your videos removing material from the head to increase compression...why is this? Clearance issues to eyebrow reliefs, deck height clearnce, or connecting rod strength issues? Thanks in advance.
Wondering if you have had any problems as a result of insufficient crankshaft end play? Removing the gasket will alter that...I admit, I don't know the predator engines, but the Kohler crank end play is adjusted with shims behind the gasket for the bearing plate.
I need your help.i,m trying to decide which engine to buy and what i need to take governor out and up grade springs .could you please tell me if the hemi and none hemi predator 420 heads have the same valve springs and how do you determine what lb of upgraded spring to use ? and where to buy them from.thank u.
So if you disconnect the leaver on the goviner with the spring hook to it is it still nessery to split the case just to remove the gear that no longer works any way
Hmmmm,.... jets,....the only difference is the size of hole in it? And you have a drill and drill bits? I'd stick drill bits in till I found one that fit and ream it to the next size and try it.
I have a 420 predator that I have installed in my golf cart. I have made a custom exhaust and bought the header , carb jet and the custom intake air filter. I also put in what I thought was 35# valve springs to stop valve float after removing the governor. But unfortunately I still have valves floating and back firing thru the carb at higher rpm. I suspect that the "35#" valve springs aren"t. Where would you recommend that I find some valve springs strong enough to cure this problem. I really wish my engine would run like the one you mounted on your go cart. Thanks, Mel
Awesome video! Thanks to you I got myself air filter kit and jet :) can you please provide link to the spacer that is needed for attaching the filter adaptor and filter kit? I don't see it in description. Thanks much!
I ordered one from the Amazon link and it appears to be too small. Do you know if Predator has changed dimensions lately? The studs on mine are 2" apart, but the spacer holes are 1.75". I appreciate any feedback you are able to provide.
Question. When you removed the oil sensor and tapped the hole for a plug, After you drill it out, instead of putting a plug could you put a 3/8 NPT fitting for use with a pulse type fuel pump? Is there some reason that is not a good place to put the pulse fitting? Again, great videos. Thanks.
I have a question about the governor removal I'm building a cart and I'm using a Honda 390 and I've never removed one but I e had a couple spin out on riding mowers so what keeps the engine from racing out of control
Purchased trail master mini bike today thanks to you. Where did you find 52 tooth rear sprockets.any idea where to get parts to make this bike street legal. Thanks you guys are awesome yehaw GBlain
I'm curious I see the point of removing the governor but why remove the low oil sensor it could potentially save your engine, sure they are cheap but it beats pushing your go-kart out of the woods if you run out of oil.
+ARednecksLife if you take a left hand turn hard the engine will shut off. You can leave yours in but it is useless on a go kart. It is more for pressure washer and generators, so if they get knocked over it won't blow it up.
Red Beard's Garage I got basically the same engine (9HP) from Princess Auto here in Canada on mini bike, do you got a link where I can find that air filter kit?? I'm definitely doing the governor mod, I'll consider the low oil shutoff.
On the 420cc Can you upgrade valve springs to the 18lb or more after govenor removal without replacing rod and fly wheel I'd like to get the rpms without spending an arm and a leg
I'm doing the same thing but for a mini chopper. Would I do the same set up, throttle wise, when using a handlebar style throttle? Like after removing the govner.
i have a suggestion, a 301cc 8 hp predator Governor removal. i have an idea what to do, but the last time i did that i had some bad luck with it because i had a 6 hp Tecumseh engine originally on it but i dont wanna risk having it run away like it did before
Cool tank!! Motor looks good with it. Here is a tip you might not know. The valve cover is silver zink plated. Pull it off and buff the zink on it. The outcome will look like chrome and will match the shine on the tank Harbor Freight sells those buff kits with the the compound, you want to use the red rouge one.
Can I put something like that onto a motorized bike? If so what’s the biggest motor that I can put on a occ schwinn stingray chopper and a low rider?? I’m trying to find something where I’m going about 80+
Would disconnecting the governor arm from the throttle achieve the same result without getting into the crankcase and removing the governor gear and arm?
Hey Red Beard, if I remove the governor from a predator 420cc do I need to change out the flywheel and rod to a billet set-up or can I leave it. Thank you, Robert
hey Redbeard what's up great demonstration I want to put a 420cc on a mini bike chassis do you think that will fit on a Baja mini bike chassis with minimal modifications for mounting or should I look for something a little bigger concerning the frame what are you thoughts on that brother
Red Beard's Garage I was thinking just the mounting plate may need some new holes drilled in it to get the engine mounted and adjusted for the length of chain those Predator Motors at Harbor Freight pretty good buy for the amount of money and they're very reliable in my experience
I have a mud motor with a predator on my boat.. the header pipe has to go out the back and not to the side. My question is will it run ok with a straight pipe going out of the back? I've seen pipes that curl then go straight back but they're expensive
Im building a 301cc for the first time and THIS is one of the only and most helpful videos ive found.your channel has help guide me threw any hiccups so thank you👍🏾
I cant believe how much of a difference there is power wise between the 420 and the 212.. love this block.

Its always hard to trouble shoot something over the internet. Will it start right back up after dying?
Austin Davis possibly your low oil sensor... bypass it if you haven't already
yo
check your fuel filter it could be clogged
since it dies before it even gets hot and idles fine u def have a fuel issue
Thx for the great video.
Do you have a video for an oil drain pipe setup?
+red beard is that a new style predator engine, havent seen that valve cover style before
+ill state it's the big block 420cc
ok so under the vlave cover is it different than the other style 420cc predator
Ive got that same flathead with the red handle, the grip slips real bad when you try to tighten something, sets everything to about 15ftlb
What jet did you use? Non of your links go anywhere anymore?
if you leave the low oil shutoff in the engine it will automatically shut down in event of a rollover. just had that happen while drifting my off road garden tractor! LOL!
And will shut off when traversing steep terrain!
coming out awesome. could you make a gasket for the carb if you wanted to
+Jason Ouellette it would be hard because it needs to be spaced out to work properly
I just let the gas drain off and evaporate because is really good for the atmosphere lmao!!! I'm dying brother
Can you make a vid of this modded motor being used as a mud motor on a John boat. I'm curios to see the performance it will have as a mud motor.
I would if i had a mud boat. We are trying to find one now to build
Id also love to see something like this
I am building a mud motor for my duck boat using this same motor...what would you estimate the HP is now after you modded the engine as is in the video?
With the ported heads 45
Plumbers putty works well when tapping the block too
Ireally like watching your shows, but I have a question. What will happen if you don't take the governor completely out of the engine rather than just disconnecting the linkage and hooking the throttle cable right to the carb?
You risk it damaging your engine. I have seen where some people have did it that way and broke there oil dipper on the rod.
I haven't run across any of your videos removing material from the head to increase compression...why is this? Clearance issues to eyebrow reliefs, deck height clearnce, or connecting rod strength issues?
Thanks in advance.
I was thinking for a second like " why would you build a motor this big and put on a children"s cart" Lol Love your videos
Wondering if you have had any problems as a result of insufficient crankshaft end play? Removing the gasket will alter that...I admit, I don't know the predator engines, but the Kohler crank end play is adjusted with shims behind the gasket for the bearing plate.
I need your help.i,m trying to decide which engine to buy and what i need to take governor out and up grade springs .could you please tell me if the hemi and none hemi predator 420 heads have the same valve springs and how do you determine what lb of upgraded spring to use ? and where to buy them from.thank u.
+Red Beard's Garagen Why not use this motor on the schwinn chopper bike??
I would have to completely redo the frame to fit it. Its more power than we need on it also
So you wouldn't suggest putting a regular motorcycle engine on it or a v twin lawn mower engine? I want to make mine go as fast as it can! :)
So if you disconnect the leaver on the goviner with the spring hook to it is it still nessery to split the case just to remove the gear that no longer works any way
+Allen Lackey I would definitely open it up and remove everything. It's not necessary but I have had a subscriber mess his engine up by leaving it in.
Without replacing the stock valve springs and doing this upgrade how many more rpm's can you get with out throwing a rod or damaging the engine ?
+Red beard's garage do you know of an exhaust like the one you used that would fit a 212cc?
+legitly gaming you pretty much have to make one. There will be some up for sale on go power sports soon. Designed by me. 👍
Red Beard's famous words @18:05 "The most tedious part about tapping a hole is getting it started".
What size is the jet? Gopowersports don't have the stage one upgrade kit n haven't for months now. So I gotta get it all separately
Not sure. It all depends on your altitude
So those harbor freigh engines pretty good.
Did you say what size tap you use? If so I must have missed it unless you use the 3/8th tap for both? Thanks for the info.
In your opinion which mini bike should I buy for adult 198 lbs . Will be use off road thanks
The trailmaster MB200 is in my opinion the best mini bike on the market
Just picked up a 301cc, it has begun
I watched a similar modification but he put in heavier valve springs to prevent valve float with the higher rpm. What max rpm will this safely run?
You done a video for the 212cc doing a govenor bypass..can't you do the same for the 420cc?
Yeah you can
Ok..thanks for responding.
So unplugging the black wire deactivates the oil sensor if you don't feel like taking the engine apart?
Unplugging the yellow wire will deactivate it
Red Beard's Garage thanks that'll save me a little time.
I noticed that you are working on a hemi motor. have you found replacement valves for it?
+jason evans yeah I just bought some off of eBay. I bent mine by over reving. Lol
i recently did the same. do you happen to remember the vender you bought from? it is not a standard valve its 33mm
Hey Red Beard..are you going to be doing a valve spring and carb upgrade on the 420cc?.. If so what valove spring and carb will you be using?
+Ken Cromwell yeah very soon there will be a video. 35lb valve springs and 32mm mikuni
Thanks..can't wait to see it..keep up the great work..God Bless
What's the best way to do the throttle on a 420?
Hmmmm,.... jets,....the only difference is the size of hole in it?
And you have a drill and drill bits?
I'd stick drill bits in till I found one that fit and ream it to the next size and try it.
when you said 2 10mm I was like is he like us does he have to find the 10mm wrench first
Hey red beard where can I get the red hoses for my predator 212 and what sizes should I get for the fuel line and the valve cover vent ?
Im pretty sure amazon or ebay will have it and i think the fuel line size is 3/16
I have a 420 predator that I have installed in my golf cart. I have made a custom exhaust and bought the header , carb jet and the custom intake air filter. I also put in what I thought was 35# valve springs to stop valve float after removing the governor. But unfortunately I still have valves floating and back firing thru the carb at higher rpm. I suspect that the "35#" valve springs aren"t. Where would you recommend that I find some valve springs strong enough to cure this problem. I really wish my engine would run like the one you mounted on your go cart. Thanks, Mel
55lbs is what I am going to next
Do you have a source for the 55# springs?
Awesome video! Thanks to you I got myself air filter kit and jet :) can you please provide link to the spacer that is needed for attaching the filter adaptor and filter kit? I don't see it in description. Thanks much!
I just added the link. Thanks for reminding me and thanks for watching
Thank you very much!
I ordered one from the Amazon link and it appears to be too small. Do you know if Predator has changed dimensions lately? The studs on mine are 2" apart, but the spacer holes are 1.75". I appreciate any feedback you are able to provide.

Question. When you removed the oil sensor and tapped the hole for a plug, After you drill it out, instead of putting a plug could you put a 3/8 NPT fitting for use with a pulse type fuel pump? Is there some reason that is not a good place to put the pulse fitting? Again, great videos. Thanks.
Its too low and oil will blow into your pulse pump. You need to use the governor hole in the top of the block for a pulse pump.
That answers my question. Thanks for the help.
What length was the 3/8” bolt you used to plug gov arm hole?
Ben, hammer home a piece of short round towelling rod or use a length and cut it off after.Seal/lube it with some RTV.Simple. Trev New Zealand

Question. I got that muffler and a 420 header pipe, but how did you attach the muffler to the header pipe?
I bought everything o the list. and installed it but i still dont get the throttle linkage part. I thought you were going to make a video on that.....
+eldeaquellas13 I did on the Honda gx270
oh ill check it out, thanks for replying!
+eldeaquellas13 no problem man
can u send me the link to the video? im stuck!
I have a question about the governor removal I'm building a cart and I'm using a Honda 390 and I've never removed one but I e had a couple spin out on riding mowers so what keeps the engine from racing out of control
Do these motors have to use gravity fed tanks or can you use an outboard boat motor tank instead?
Purchased trail master mini bike today thanks to you. Where did you find 52 tooth rear sprockets.any idea where to get parts to make this bike street legal. Thanks you guys are awesome yehaw

Why would you have to remove the governor if you removed the governor arm?
Air Filter & Performance Jet for the 420 predator is out of stock at gopowersport .would you know another site?
+Alberto Agront they should be back in stock soon.
Alberto Agront try Amazon
I'm curious I see the point of removing the governor but why remove the low oil sensor it could potentially save your engine, sure they are cheap but it beats pushing your go-kart out of the woods if you run out of oil.
+ARednecksLife if you take a left hand turn hard the engine will shut off. You can leave yours in but it is useless on a go kart. It is more for pressure washer and generators, so if they get knocked over it won't blow it up.
Red Beard's Garage I got basically the same engine (9HP) from Princess Auto here in Canada on mini bike, do you got a link where I can find that air filter kit??
I'm definitely doing the governor mod, I'll consider the low oil shutoff.
So I have a question do I need to put 50 ilb springs in if I take the governor
On the 420cc Can you upgrade valve springs to the 18lb or more after govenor removal without replacing rod and fly wheel I'd like to get the rpms without spending an arm and a leg
You can upgrade to 50lbs springs but I would eventually change the rod and flywheel. It will last for a good while though stock
Red Beard's Garage but will the 22lb springs fit so I don't hit super high rpms
I'm just trying to avoid valve float with the springs while not having to sweat breaking the rod somewhere in the range of 4500 to 5000 rpms
I'm doing the same thing but for a mini chopper. Would I do the same set up, throttle wise, when using a handlebar style throttle? Like after removing the govner.
Just realized this video is 6yrs old 😮
i have a suggestion, a 301cc 8 hp predator Governor removal. i have an idea what to do, but the last time i did that i had some bad luck with it because i had a 6 hp Tecumseh engine originally on it but i dont wanna risk having it run away like it did before
This thing is seriously bad ass
+James7796ify thanks man
Cool tank!! Motor looks good with it. Here is a tip you might not know. The valve cover is silver zink plated. Pull it off and buff the zink on it. The outcome will look like chrome and will match the shine on the tank Harbor Freight sells those buff kits with the the compound, you want to use the red rouge one.
Can I put something like that onto a motorized bike? If so what’s the biggest motor that I can put on a occ schwinn stingray chopper and a low rider?? I’m trying to find something where I’m going about 80+
Hey Red Beard can you post a link for that pit bike muffler, want to put that on my gokart
Just did look in the description now
Would disconnecting the governor arm from the throttle achieve the same result without getting into the crankcase and removing the governor gear and arm?
Do you have to upgrade the rod and flywheel like a 212 or no after deleting governor?
Hey RB are the stock cams on the 212 pretty solid metal?? Somebody once told me that they were plastic.
I believe the Hondas now have plastic cam gears. The Predators are metal.
Red Beard's Garage as always thank you,sir!
What number jet do you use when doing just the intake and exhaust upgrade
RBG can I flip my 420cc powermore vertical to a horizontal without any problem or do I still need to modify the oils splash stick
Would you what is the distance from block to center of belt on a 780 drive clutch? Still waiting for mine just wanna do mock up for block space check
Have you put heavier valve springs in a 420cc predator?
No but I will be in about a week. I have a lot more upgrades for this engine coming in the mail now
sounds good looking forward to see more. I'm in the process on doing mine.
If you disconnect the govener arm from the top of the engine do you have to remove the wheel and j shaft inside the engine?
Hey Red Beard, if I remove the governor from a predator 420cc do I need to change out the flywheel and rod to a billet set-up or can I leave it.
Thank you,
Robert
How wide is the 420cc with the gas tank off? Just wondering if I could slip it between the 11" bars of my engine cage.
With a cvt its 19" wide at the widest point
If I bought a header and a air filter for my 18hp duromax do I have to buy bigger jets for the carb to?
Yes sir
Hey Red Beard I am doing a Governor removal on a 18hp duromax engine. Will it be pretty much the exact same thing as the predator?
Yes sir. Should be the same exact process
hey Redbeard what's up great demonstration I want to put a 420cc on a mini bike chassis do you think that will fit on a Baja mini bike chassis with minimal modifications for mounting or should I look for something a little bigger concerning the frame what are you thoughts on that brother
Im pretty sure it will work will little modification.
Red Beard's Garage I was thinking just the mounting plate may need some new holes drilled in it to get the engine mounted and adjusted for the length of chain those Predator Motors at Harbor Freight pretty good buy for the amount of money and they're very reliable in my experience
you put together some awesome moters
+Alex's lawn care and snow removal thanks man
Curious... Do you think that an oil catch canister would fit nicely where the smog box once was? Maybe using the stock brackets?
I think the way it's mounted would still blow oil out of it
Gotcha. Thanks for the response. Keep up the good work.
I have a mud motor with a predator on my boat.. the header pipe has to go out the back and not to the side. My question is will it run ok with a straight pipe going out of the back? I've seen pipes that curl then go straight back but they're expensive
red beard what do you think of the animal 206 race engine im kinda having problems with mine
+GoKart Garage never heard of it to be honest.
thanks for replying red
Got a crossfire 150 off road 2 seater looking to upgrade soon. Do I go 420 or 670 could u also help with sprocket size big also
If you can afford it the 670cc is the better option for sure
