Also when you use the grinding compound you will notice on the video when he cleaned it the valve had a line bout in the middle of the valve angle. That is a good sign that the valves are seated good to go ahead n put them in. I haven't been in the small engines in 20ty some yr's n my lil son is turning 8 and I went n got about 6 engine's one of them a Tecumseh 8hp that is supp already built with a lot of compression, piston, cam, lifters, valve's, rod already changed with a 1 inch shaft. I didn't know till recently they had fuel injection for these n I have seen some put turbo's on some. I would like to see a video like this one that starts to finish with it, some are using the mega squirt with some briggs, but I haven't found too much info on them. But great video!!
looking forward to seeing this engine come to life.
Yep, just raced it Friday. That should be a good video.
your engiee mod tutorial series is helpful ican use it as a reference for car engine modding
Awesome presentation!
Any idea on if there are performances mods similar to what you used but for a 6.5hp Briggs and Stratton flat head and to convert the motor from horizontal engine to vertical?
I have royal enfield continental gt 535 and I'm gonna install a performance cam which my mechanic will custom make for me. should I be adding valves and lifters and push rods also should I buy a power commander (piggy bank ecu)
Awesome video !
if you don't know how mutch these videos help, I have 2 kart frames, 3 wrecked 4 wheelers,and 8 dirt bikes in the family to work on I am only 12 but my dad can't do it all for us. thank you
good vid, thank you for the tips, I will use this when building my karts
no problem
2:49 fun thing
i had to hot glue mine when i was doing my 2 cylinder onan engine 2 week ago
because the sucking cup dosen't suck enought
lol
Hey good job! I am planning a build for my sons race kart over this winter. I will. Be in touch with you with questions lol. Good job i like watching your videow, keep them coming
Love these videos I learn a lot about engines from them. I sort of want to see how good the karts go after these upgrades are done, that would be cool. Or even just a before and after of the engine running.
you will get more than that. There is no before because this engine was purchased just as a bare block, so the first time it runs is the after.
haha fair enough.
KartFab where do I buy my billet lifters for a 212cc
Доброго дня! Ви купляли вже готовий розподільчий вал з розширеними фазами чи виготовили самостійно? Дякую!
Where did you purchase valve spring compressor?
Very cool video and well said
I wanna know about the 6.5 HP engine on the coleman ct200u!!!!! Please!!!!!
if you put a camp in one of these engines I have seen on the dynocams website that it is recommended you to weld the lifter bore. Is this necessary if you don't plan running the engine at high rpms?
depends on the cam. High lift, aggressive ramp cams put a lot of load on the valve train. A mild cam like the 94ss doesn't. Its more about durability and longevity than 'necessary'
I have one question? Is there a difference between Valve lifters? Does it matter which is suction and which is exhaust?
How can i get those most power out of my animal i have a 315 came in it with springs and the whole performance set up so far with roller rockers all i need to do now is figure out what's going to be a good carb set up
Need help have a box stock raptor intake valve keeps hitting spark plug electrode when I Chuck a rev
ok so you are saying you have a 1) box stock 2) raptor? So if you look at what you just said, you said you have a honda gx200 clone and a briggs and stratton 5 hp flathead intake valve... Makes no sense. Your problem could be a number of things, but lets start with the basics. What engine do you have? What changes did you make to it?
hi! what do you think about brass counterweights instead sunchro balancer in regular mower - just for mowing , as i am not interested in mower racing..aren't they going to weeken the engine? thanks
If you are just mowing, you shouldn’t mess with modifying. Stock=safe
I took apart a brand new predator head that’s never ran ( to port ). Is there an advantage to lapping the valves with a brand new engine?
I had a question i need help making a break system like a rod for my manco kart just wondering can u give me a few ideas I'm running disc break and caliber as well
+amps2010 look up my go kart brakes video. Set up the pedal and the rod the same way. Brake caliper is set up a little different.
How much would this entire build cost
I just ordered a predator 212cc I'm just going to ride it for fun. Does the valve springs come installed already in the motor or do I half to put them in.? And is there any other parts that don't come with it that I need to order? Please tell me
All you have to add is oil and gas.
Thanks Grant
I went with Black Mamba cam
I'll let you know how it
turns out.
Or not...
I've been looking into racing karts. Do they have rules about driver weights? I only weigh about 90lbs so I thought I might have quite the advantage in terms of top speed and acceleration.
+David Vermillion yes they do have strict rules that vary track to track
Are there any retainers that go on the top of the valve springs or do the springs just sit against the block? Thx.
Retainers are only for valve tips. Nothing sits on the block with these ones other than the spring.
do you need to re adjust the timing after installing a perfirmance cam?
+Humberto P timing should be set for the target rpm range and fuel type, which is usually included on the cam card.
First of all thanku very much sir! It was very useful! Please let me know
how can i change the stroke length of my engine without changing the connecting rods?
or what are the ways by which we can increase our compression ratio?
+Satyam Priyam Roy changing the connecting rod won't change stroke. Changing crank will. Increase compression by: Boeing larger, bigger piston, deck block, mill head, thinner head gasket.
Lapping valves only works at startup. Correctly done valves and seats have a 1° difference on the angles at ambient temp. At operating temperature the heat difference between the valve and seat causes them to expand differently, taking up the 1° difference.
Hmm, you are probably right. But id rather hand lap valves that are all buggered up and pitted, than take it to a machinist that will charge who knows what.
what camshaft did you use? stll trying to find some Flathead parts for my mini bikes 5 HP Flathead
94ss
Hey grant, know your pretty busy but advice would be godly. So I have a 5 hp tecumseh year 95-99, have about 1/4 inch or more play n the crankshaft. Can push on shaft OR flywheel and get the play. Any suggestions for problems or solutions to eliminate some. Also con rod has slight play. Really don't want to replace to much. How can I rig it just to somewhat safely move it on its own power. Does have spark.you are not liable for any of my actions whatsoever. just shoot ideas @ me please.
Crankshaft spacers. You can order from ARC racing or any of their distributors.
Where could I buy some of these parts like billet conrod lifters springs and cam. Thanks
Out2win.com
I have a sigma 212 and put on a stage 1kit on IT and I fell air coming out some whare near the carburetor I do not now why and the kit only gave me 2 more miles per hour is this right or do I need to do something
the engine's flywheel has a fan on it, so when the engine is running, it blows air over the engine,so you should be feeling air coming out all over the place when its running. Stage 1 kit only gives you more flow, which gives you more power (NOT RPM INCREASE). If you want to achieve higher rpms after the stage 1 mods, you need to remove the governor, and install heavier valve springs, and possibly a billet connecting rod to support those RPMS with proper oiling.
Looks like itll be a good runner im building a flat head now its a tiller block but has a new raptpr 3 piston arc rod arc 3hp flywheel has the brows shaved and ported and polished intake and exaust well i didnt polish the intake left it rough got a raptor carb for it just have to pic my cam and valve springs
94ss and 20 lb springs would be my suggestion
I ended up getting a 107ss for my build
I looked on out2win.com and couldn't find the springs. what does "19lb stock appearing" mean? Love the videos. Thanks.
you may have to call them its on this page though. out2win.com/catalog/raptorvlv.html#AM
I just put 36 lb springs just wanted to know what’s the best can I can use for my 5 ho flathead
+Crazyjesse11 cams need a certain spring pressure, timing, and compression ratio. It’s not a question of ‘best’ rather, what combination is going to produce power at the RPM range that I need?
You check the valve lash with the springs in or without?
In for final check. For ohv the must be in. For flatheads you can get away with having them out and pushing down on the valve when you check.
I have a 127cc briggs 550 series and I'm trying to find performance parts as well but don't know where to start. Briggs don't seem to have much aftermarket.
broken smile its really hard to find parts im trying to find parts for a reasonable price and its hard. Ive been looking on ebay and i found some parts. The only mods i would really do is a pistion arm,valve springs, and governor removal, porting and polishing,cam and a carb/exhast its alot of simple stuff(i have a 5hp briggs that had a stuck valve which is fixed now but i need a valve tappet its hard to find one for me (edit:spelt tappet wrong)
Will a 212 camshaft fit in any honda clone? (I have a 168fb honda clone generator motor)
+Olivier Beucken no
Ok thanks
I have a 196cc Mini Bike that am in the process of modifying a little at a time and it's these type of how to videos that I've been looking for being I have never done this stuff before. I'm assuming all these engine mods will work for me as well even though mines a Mini Bike and not a Go Kart. I will be buying a Billet Flywheel, Billet Rod, and Mod 2 Cam next and will have to write down step by step directions as I'm watching these videos.
Yes will work for small engine
Maybe you know where can I get a performance cam and springs for my old 8hp flat head B@S? I can't find anything for it. Has a really wierd rod on it too that I have never seen before and both of the valves are same size too.
Also will a new style electronic coil for a 5hp work with a 8hp ?
No idea. There really never was a performance market for those engines. Coil might work but you need to verify timing.
What's the carb set up on the flathead. Doing up my 5hp.
Get a PZ22 or knock off pz22 carb. I got a gx200 carb on there but it’s not as good as a slide carb.
If this is done to a riding mower will it hurt or help the performance. Just say a 24 hp Briggs 2 cylinder
+nice1n601 yeah a cam with more lift and or duration than stock will help mid and high end torque
How power will this whole series add to a Briggs or a Predator?
I don't have a dyno, so I couldn't tell you.
I have a monster moto and i have two rodes fell out that go to the liffer so how do i but them back in on a mm105
Very carefully
Briggs Flathead 8hp... I can't find any performance parts for this engine. I would like to have (billet) flywheel and all the internals accept crank. If no parts are avalible does anyone know if the parts for the 5hp fit and are feasible
yeah thats not a common one.
I have a cmxx ohv 136cc engine (very similar to a 212) I have removed multiple different govenors on multiple different engines and sizes but on this during the removal the camshaft fell out and does not have the dots to line the cam up with the crank. What should I do? Any help would be greatly appreciated!
Do a bit of searching. Id check extra carefully for any sort of indicaiton or marking on the cam and crank gear. Worst case scenario, you would need to get a cheap degree wheel (or even print one yourself and stick it on the crank), then look at when the lobes are letting the valves open and close in relation to TDC. Good luck
KartFab thank you very much for the information
Where would I get a nasty cam for a 3.5 hp ? I looked at the site but I can’t make heads or tails of it
A 3.5 hp isn’t enough motor to even mess with. Try calling up a place that specializes in Briggs flathead parts e.g. out2win.com
IM STARTING TO BUY PARTS FOR MY 212CC HEMI BUILD AND ID LIKE TO KNOW WHATS THE BEST COMBO OF PARTS FOR THE BEST PERFORMANCE
depends on what you want, i ususlaly reccomend a mild cam and target max rpm of 6-7k rpm
I'm going for at least 8000 rpm
What can I use for an 11 hp b&s set up just curious as to what’s Available. Thanks
Like an old flathead? Not much. You can always do intake/exhaust/jet on any engine, but only the popular engines are going to have lots of performance parts.
Intake/exhaust/jet will get you to 5500 rpm before valve float
in what order would you say woulb be ideal to start upgrading?
its just my opinion but, id do:
stage 1)intake, exhaust, rejet, governor removal
stage 2) cam/timing advance/billet rod/valve springs.
beyond that there are many other things to do, but those are the basics.
KartFab ok ill be doing that thank you your videos are very helpful. ill be subscribing.
YEH mini bike videos!!!
finally right?
Can you suggest a performance camshaft for a 10.5 I/C Briggs?
If only one existed.
Were do I find performance upgrade kit or parts to a 2017 lifan kp150 mini?
Looks like a 150cc dirt bike style engine.
@@KartFab I wish I could find the dimensions of the internals so I could get a game plan together to build it up a little.
Hey I was wondering if you were ever thinking about making a single person off-road go kart?
I have thought about it, but I will not be doing a 1 seat off road build anytime soon.
I have the same engine with no carb. I wanna put a honda carb on it, but I dont have a tig welder(only arc). Any advice?
They make manifolds for them. Get a cheap mikuni 22 mm carb with adapter for it. You will need to do some searching, i just know that they exist, not where they are.
+KartFab Thanks
Can a duramax 420cc engine get these upgrades?
I am not sure.
im on arc racing web site and i cant seem to find a performance cam for my 17hp briggs flathead, you think you could help?
+The Fab Lab 17 hp?
yes sir
Well, you can always call a place that grinds cams, and have them weld and grind the cam you have. I have never heard of a briggs 17 hp flathead. When i hear the word briggs flathead, I instantly think of the 5 hp flat heads commonly used in the 90's
WOW, They make all this stuff for these small engines!?!?
Yep!
I'm planning on doing this to a 8 horse Briggs flathead, any suggestions for a carb? I don't want to use the updraft carb
+Jarred Random so here is what I know: the dirk bike slide type carbs work the best. A 22 mm mikuni slide carb is good for the 212cc predator, and the 32mm is good for the Honda gx390. Measure the intake valve and go 2mm less in diameter for the Venturi size of the carb. Mikuni and PW are good ones to go for. Not sure about walboro but they are used s lot as well.
the intake is 1 inch
well, id say you cant go wrong with a 22mm, not sure about other sizes.
Cool, thanks for the help
I have a Briggs 3hp
can i just use regular engine oil for assembly lube?
theoutbackbandit Yes
I second that. However, assembly lube wont drain off the parts as easily, so if you wait a long time between assembling the engine and starting it up, that could be a problem. Assembly lube (or even break in oil) has special additives that will protect your cam lobes during break in. So moral of the story? Unless you are getting a high lift cam with an aggressive ramp, and heavy valve springs, you probably don't even need assembly lube. One trick some people do is they use their regular/stock valve springs during break in (2000 rpms for about 20 mins) , then swap to the heavy valve springs and dual valve springs, then change the oil.
theoutbackbandit royal purple is not only of the gods but they also make assembly lube.
KartFab its called zinc that's what's in the assembly lube real thick
I need a heavy duty rod for my fh5 Briggs around Tampa Florida
I was wondering why does my pull start rip out my hands I set the valves right and the flywheel key is not split ? Do you what it would be
Does your cam have a compression release? Are you pulling the engine to the compression stroke, then pull starting it?
No it’s doesn’t a 94 ss cam for 5hp Briggs and yes I am then it starts up
you just arent pulling hard enough. intake valve lash should be .005" and exhaust shoudl be .006" I have the exact same cam and a light flywheel. It will kick back on you if you don't pull hard and don't pull to compression. Just yank it HARD. If you still get kickback, consider installing a snowmobile handle for pull start so it wont hurt if it kicks back. If you still get kick-back, you need to go to the gym and not pull it like a sissy :-)
It's a flat head with stock internals carb been modified for methanol don't think the motor is ever been a part it sat in my garage for 10 years
I still dont understand how your valve would be hitting the spark plug, unless you put in the wrong spark plug, modified the head somehow (stock gasket, not milled?). Or put in a different cam that caused the valve to lift higher. If i were you, id pull the sparkplug and check it against the users manual. Some spark plugs are longer than stock, and fit in the hole, so i would suspect this to be a likely cause if no other changes were made.
Dyno CM cam or Isky Black Mamba for my clone

Thanks in advance !
Frank from Connecticut
you cant have it all with a cam. the cm will probably be better at low rpm, and the black mamba will probably be better midrange and high rpm wise.
@@KartFabThats Absolutely True Grant
Tony @ Dyno cams said cm cam is great @ top end
But loses a little bottom end. & is basically desiged for a bigger Carb Set-Up
Tillotson / Mikuni
I'm running a 22m.m. Japanese Mikuni kit
Isky says Black Mamba cam produces more power Throughout the entire

But I'm using the stock valve train & it has a very Aggressive ramp angle.

Oh Well ! MORE OBCESSIVE RESEARCH .
Like any addiction - IT'S A PROGESSIVE DISEASE .
haha
Any input is Appreciated
Thanx Grant !
Frank
call taylor yochum at gopowersports, tell him grant sent you there to help you choose a cam. he will hook you up. Let him know what engine you are putting it on and what you are putting the engine on and he can help with EVERYTHING to get it running right. Its not just the cam but the gearing, clutch, etc.
man is there any reason i cant get my head off??? the bolts seem to be torqued so hard im just ripping them up trying to pull them out
+alex pat they should unbolt just fine if you use the correct socket.
Will normal lifters still work if there is only a small increase in the size on the cam
Yeah. The real issue is if you have heavy springs.
@@KartFab standard springs its a briggs model 28 flathead
You’ll be fine. Briggs aren’t made of Chineseum.
@@KartFab true 💪😂
Good installation video but it would have been nice if you went more in depth on how to choice which cam is best, along with rockers, and spring stiffness.
Good point. I’ll be doing more videos. Cam choice was based on what I was building the engine to do. Flatheads do not have rockers.
Anything for a kholer command single cylinder, 17.5hp?
I don't think so. You can always advance timing 2-4 degrees,, put a dirt bike carb that has a venturi that is within 1-3mm of the intake valve diameter, and do a high flow exhaust. Internals, probably not.
KartFab how would I do the advance timing? because I already have the dirt bike carb and my exhaust could be better lol
well, there are a few ways. Most people get a flywheel puller check your flywheel for threaded holes, (i actually use a harmonic dampener puller from autozone free tool rental) its the one where you can thread it in from three spots. Then pull your flywheel. A lot of engine places sell "timing keys" which are just keys that have had a tiny bit of the key shaved off. That is the quick and dirty way. If you want to be LEGIT, you get yourself a timing light for about $35, and a piston stop, and a degree wheel, and you measure what your timing is set to after measuring top dead center. Typical timing is about 22-25 degrees before top dead center, and advancing the timing about 4 degrees is plenty. You also might want to check the dimensions of your valve springs, you dont want to float the valves. You might see if you can get some heavier valve springs.
I watched all your videos on this engine build and i am planning on doing a predator 212 performance build. Here are my questions.
(1). are all of the torque specs the same for the predator as the briggs
(2). i am a kid and dont have money, so what i wanna do is like add parts on to the engine as i go on and get money and once i have everything remove the gov.... due to this, is there a certain list of what i should do first and last(like should i do the piston first and cam last etc.)
(3.) if i add all of these parts, do you think it will be safer, if not totally safe to rev my engine to full throttle w/out governor for like 20 seconds?
What cam do I get for my predator nine hemi
+Angel Speer generally speaking a mild can with about stock lift and higher duration is good all around. Mod2 is pretty popular for that.
+KartFab OK thank you
KartFab I am getting a vintage Tecumseh flathead h50.I'm wanting to hop it up petty good, any suggestions. It'll be going on a mini bike too
Thank you
lets hear it run bro
IF I GET A. 308 CAM DO I NEED TO GET A SHORTER PISTON SO IT DOESNT BEND A VALVE?
that cam is for extremely high rpms, so the lower rpms (you know the ones you will be usually in when on a mini bike or go kart) will suffer greatly, again, I would only go with a cam that has a target max rpm of 6-7k tops, the lower the max rpm of the cam *(typically) the less torque you lose. Just my 2 cents.
F 275 can with 32# springs and ultra light flywheel with a .625 carb
And I'm going to do some mild port work
why would you get that carb? Its for methanol, and its just a standard carb. If you are going to be going with a higher rpm cam, and you arent trying to pass tech for racing, then you should be looking at a dirt bike carb (like a mikuni 22 mm carb) you will need to figure out jetting and whatnot. Speaking from my limited experience, though, you really would need some good tuning skills for methanol. Gas is a lot easier to tune.
What is the duration of the cam? Looks very similar to my car cam.
241 in/ 244 ex
Thanks, I looked at the top, at the bottom not the same. Mine is 320 in.
We are talking duration here, which is measured in degrees of rotation.
Yes,degrees of duration of keeping opened the valves. It's an old cam used on hill climb. I think european cars, the old ones, used higher duration cams than american or others. My car had 260 degrees stock, but not a performance engine.A friend of mine has an even wilder cam. 345 in, 335 ex. Also hill climb cam. Could make 11.000 rpm with lightened pistons and other parts.
oh wow, thats crazy! We don't see much over 260 duration for these small engines.
I think lots of people are confused about what “billet” really means. It means manufactured from a single piece of metal. It does not mean “performance”. Both of those “lifters” are “billet”!!!
Briggs: throw the cam in torque that sucker down good to go
Predator: hold my beer I’m gonna hit myself now
I will make quadricycle can you rec about this
Im working on other projects at the moment, what is a quadricycle?
+KartFab 4 wheel bycle thanks for the message
My motor I messed up how do I fix it
I hit a bump in the road and now it doesn't run properly
I give it full throttle and it dies
Now it doesn't go as fast
It back fires to much
And it sounds like it dies for a split second then comes right back on
It badly sound like it's running well idling
empty all the gas out of the tank, clean the tank out, clean the fuel line out, and clean out your carburetor. When you give an engine full throttle and it dies, it will run with the choke on, doesn't go fast, and backfires..... those are all symptoms of running lean (which is almost always caused by a dirty carburetor).
+KartFab it's a brand new motor choke is never on while running and it runs clean gas
Have you looked at the oil level? If the oil is good, google "low oil sensor disconnect" for your engine. If you put like a predator 212cc on a kart, and the low oil sensor wire is still connected, hitting bumps or going around corners will cut it off.
+KartFab the oil is new and fine
+KartFab + the motor doesn't turn off
you never did answer my wheel hub question... also, can you do a live axle go kart build video? I wanna make my one wheel drive 80s model one seater go kart into a two wheel drive but i dont know how
had to search for the comment just barely. I cant get to all comments, but i just read it and addressed it. Yes i will be doing a live axle go kart build video, and will actually be converting the one wheel drive go kart that I built for the free plans kart into a live axle go kart. Basically you need to get a live axle kit, and weld on the axle hangars (there are two of them), then the axle bolts right up to the hangars and you secure everything else with lock washers etc. The other things I can see as problems are 1)adjusting brake location, possibly welding on a brake caliper bracket 2) engine position may need to be adjusted 3) steering not as sensitive with live axle. So with all that said, you are going to need to weld pr get someone to weld it for you to make the conversion happen.
***** what about torque converter? Do I need it or can i use my clutch? And what do i measure from and to to get the axle length
***** by the way, what do you mean you just addressed? you didnt reply. the comment is on the vacation video
you want to make sure the tires clear the edges of the go kart. Most go kart axles are around 40" long anyway.
yeah, i just addressed it by replying to you.
Hahahah that’s funny and ok that I get it to .005 .006 thanks
haha no problem, check out this page for all the cam specs www.dynocams.com/item/94ss/
how can you orientate piston rings when the rings have no marks on them
did the rings come with instructions or a little card?
+KartFab nope not a thing its a honda clone motor
+Cj Holcombe only thing i can tell is top ring and second compression are different colors
ok so i looked into it. Top ring should be chrome faced. You can tell the difference between top ring and second ring as the second ring should be black faced. Top ring should have a 90 degree (flat) surface that mates against the bore. The second compression ring (black faced) should have a slight angle on the edge that mates against the bore, the edge that touches the bore should be down (e.g, when installed the bottom edge of the ring touches bore. Check out the factory service manual for a honda gx200 (thats where I pulled the info).
+KartFab thanks man thats the way i put them. the motor crank but died in about ten seconds its acting like its out of time. any suggestions on the problem. it tries to crank but backfirs out carb. i pulled the cam 2 times to make sure it was all lined up and it was.
Right because SAE 30 is clearly assembly lube.
Yep, and I didn’t mix ZDDP additives with SAE 30 for break in. You know, you should probably use synthetic oil for break in because you’re so observant.
Calm Down Man Just Messin.
And I’m serious? Phhht
but, not mention of tecumseh. guess we're bread of our own :P
haha yeah, more like TECRAPSEH! actually i have an OHH60 i just got a cam for, billet rod, springs, and will port it, and put a 22mm mikuni on XD
thats tough, you might want to look into getting a decent flywheel but then just having a machine shop machine the taper, then set timing on your own without the key. Just a thought.
That's not half bad idea! Better than 2000.00 USD for a custom billet.
Quick question are the valve lifters supposed to sit on the camshaft when installing or it doesn't matter?
Doesn’t matter
