- Another great video by Ezeetrade Racing(EZR)
This is our first complete video of how we port a motor. YES, it is not the most perfect porting in the world as the pros do it with all the high tech equipment, but our results are fantastic.
This will be the first of many motors as we launch the New EZR32 motors for sale.

Loved the video! I think you do great work my friend!
Thank you so much. Really appreciate the support!
Everyone with a lil bit of courage can do this at home, even just small changes, smoothing, matching can make a HUGE difference in the way these lil engines run! Don't be afraid and tackle it, pickup a basic Dremel kit with a variety pack of grinding attachments and just go easy at first, try it again and then go further if you want. U really can't screw it up if you just stay simple with it. Try and think, if I were airflow, how would I want to flow? Keep it simple and your efforts will be rewarded I promise u that! Great channel buddy!
Very true
You should see some of the stuff they do to chainsaws. What he did was just mostly basic stuff. I've seen people do Finger ports trying to squeeze every little bit out of them. Keeping it basic is smart really. If you do advanced stuff wrong, cylinder is trash.
Just picked up my first baja 5b and wow these things are fun. I've run Nitro and electric rc cars before and they never put half the smile on my face that my baja did. I look forward to porting my first motor and long laundry list of hop ups!
In 2015 I packed up all my other RC cars and bought my first Baja. Never looked back.
Enjoy it my man.
great video ryno and now i own her...amazing power
alex mamaloo hi bud do you still run the tall 26/48 rovan gears that were on the baja in this video.
woopwooop.
Freaking awesome work buddy great job porting that 32 really made a difference in the power band 💥👊
Thanks man. Very good porting videos coming up
That’s cool there’s an access for the transfers I’ve never seen that before
Rovan will be changing that soon. Unfortunately.
You can still port a transfer without that access, but you have to use really small burs and it's MUCH harder. I'm used to doing it that way on chainsaws.
Magnificent this preparation has you gain something power torque rpm !!😍💯💯💯💯💯💯
Thank you very much for the support. 💪🏎
That's THE best porting video on CZcams right there!!! Nice work !!
Look at the flow in the case and cilinder... there is al lot of power there ;)
Very true. Getting better
WOW! Great stuff! really enjoyed this video. Thank you
Pleasure man. Hope to do some more porting videos in future,
So update
Followed yr instructions re this motor. Put it together and damn she runs.
So happy. Sorting out my carb as it was flooding out the intake. Changed the diaphragm and it’s improved but still over fueling.
Will changed the needle next and that should sort it out. Did the metering mod spring also and that seems fine
So thanks for providing instructions on this really appreciate it man
If yr ever feeling generous. Perhaps a tute on a 29 or 26cc would be great
Once again thanks
Good day. We are very happy it helped. We will be posting lots more videos detailed videos very soon. Just moving shop and getting settled.
Such a pro, that good don’t need to tighten to specs
Yup, been doing it for 11 years.
nice work ryno it packs a real punch now
Very nice result. Strongest 32 I've ever done
You can shim the whole barrel up by a few millimeters. I have done this on my kids pee wee 50 motorbike and it also helps to exhaust gasses quicker. Makes a difference i promise. The slight loss in compression is made up and them some by this mod...
Thanks man
thanks for posting this up buddy, half way thru porting same motor in a basher i bought for nothing though needed tlc,
good compression but broken bits n bobs, ill let you know if it goes well from Australia
Howzit! Thanks for the comment! Hope its still going well!
Awesome vid man, can you give me some tips or pointers on mine, I wanna try porting for the first time on a dying zenoah g320rc it has the removable covers like yours
We will do some more detailed videos soon! Stuff people can do at home.
I can feel the 130 db that this car makes
Thanks man! We got some big boys coming this year. Stay Tuned!
wow you can see the difference clearly. i got a 29.5ccm from a friend and it doesn't run that well with the same exhaust.! i know what i will do tomorrow. 👀👌🏼🔥💥💥💨
Hope you getting some smoke in the air bud! Enjoy it!
Excellent, enjoyed it, nice work!
Thanks man
Hey easy trade would the head of the engine have a marking for the size of ccs my rovan engine is the 4 bolt style head but don’t know what size the pull starter cover housing is red no removable ports it’s got lots of power
No Rovan does not have markings. You must measure the piston and stroke
More Such films
Coming soon!
great video bro. can you do a porting video on a Zenoah or cy 26cc
Will do. Coming soon. Busy with a few 32's then we will look at doing a EZR26 👍
Cool video man! I would love to see more. In the future maybe a before and after comparison test like a timed 100m run.
Will do! Lots of before and afters coming this year.
What is the vest carburetor for hpi Baja 45cc
Walbro 990 or 1107
Hiya mate do you think it's better to port a brand new engine or a used engine
If it's professionally done then new is best, as you do want the longest run time on it. If it's for learning or testing then a used engine is best as you can also see thr difference cutting makes.
@@EZR thanks my friend it's a brand new 35cc I just purchased and I was going to get it professionaly done my friend will I have to do some heat cycle's first before I get it ported or is it ok to do it straight out the box :-)
Pleasure bud.
We prefer to have them ported straight out the box. Gives the porting guys a cleaner canvas to do their art.
The current lot of Rovan 32cc and 36cc motors have an integrated side scavenger port cover that is completely covered, making it difficult to perform such port processing.
Very true. The biggest difference we have seen is by changing the squish/piston gap. Big torque increase
Watch tinmans saws. You can make a degree wheel cheap with a cd or dvd. He explains its long hes a talker but worth it if you want everything you can get out of a saw/baja engine. This is very goid video except lowering the cylinder your dropping the duration or time ports are open and they open later close sooner. But this engine did seem to run very well had lot of tq. Tinman porting is more for topend high rpm hp. But with right clutch springs itll get it up on the pipe and make more power overall. Good thing with a degree wheel you cant over port it. If your exhaust duration goes past 180 its a paper weight very few engines run right over 180 deg. You can set your blow down aswell the distance between top of transfers to top of exhaust theres simple math to find in deg your blow down. I believe last yamaha jog cylinder i ended up around 30 deg of blow down. This is a goid video if you dont want to use a degree wheel by widening the ports and helping the ports flow your gonna gain without scraping the cylinder but raising ports really wakes up a 2t. But dont do it without a degree wheel or youll be throwing the cylinder in the trash. All this porting is pointless aswell without a pipe. Youll gain some but resonance helps refill the cylinder. The pipe is the biggest mod for one of these over a box exhaust. This baja has a nice pipe on it. Overall this thing rips but i wonder if its lost overall rpm due to lowering the cylinder and not raising the ports back to there proper hieght. If gaskets 1mm you raise ports 1 mm. Thats eaaiest way youll gain compression and duration no degree wheel needed. 2 stroke stuffing is a good channel to watch but hes building sime handmade super high powered low cc engines. But he explains everything in detail. Hes prob the smartest 2t guy on youtube. Im in no way lnocking this video engine performed very well. Idk about lightening the piston ive never done that or seen it before i hsve opened ports in pistons before no balance issues bit me in the butt. Im going to look into lightning piston. I know in dirtbikes pisons explode so im not sure if thats a good idea but these pistons are way lighter than a dirtbike. Good video good content. Like that buggy. I got a 5t but dam its heavy think a baja 5 would rip with weight difference
@braxbarrett4398 thanks for the info man.
I might get back into porting in the future but we have outsourced all the work from this year. Been working great. The guy who ports for us does check port timings and don't push it too far. We also don't lighten the pistons anymore. Lots of work for possibly no gains.
Perhaps we will do a before and after video on our G320
@@EZR thatd be awsome it seems like the zonahah 32cc and clone engines perform really well. I've got a 32cc china clone in my 5t. With a cheap pipe. I bought it that way recently. Guy I race with has a zanoah 32cc with nice pipe on his 5t. It screams pretty hard. Can hear it get up on the pipe when he hits the straight aways. I also have a rovan 45lt. It has goods of tq but signs off really early. I think a pipe would really wake it up. There's just a few of us trying to start a 5th scale class. The tires and body are what's pricey on the 5t rest isn't really that bad. Have another guy who's come out a few times with a taylor reed case engine but idk if it's huge advantage after watching the stock piped zanoah run. Diffinatly more power but only so much room on a track to use it. We're setup at 16ft wide lanes. I wonder how a piston port engine would run with the reeds that bolt on in between the carb and intake if piston was windowed to allow it to flow through piston on up stroke? You ever seen or messed with them? I know dirtbikes for long time ran reed valves that way the they started aiming the intake charge towards crankcase or just went to case induction all together. I just like to tinker and it'd be cool to build a reed induction engine cheap and it perform well. They want 70 bucks for that reed setup. Seen you can buy a crankcase that converts a 32cc zanoah for like 320 bucks. Suck to waste 70 bucks and time just to gain nothing and time trying to tune it. Obviously the reed case setups make great power so the 320 bucks would be a diffinate gain.
@@braxbarrett4398 I have also ran alongside some reeds and personally piston port is boss. The Reed costs more and has more maintenence. Not worth the extra money.
In my opinion the best piston port engine is the Zen 36mm. Lighter, cheaper and more than enough power to pull any 5th scale.
Excellent work, thanks for sharing
Hey bud got a question i have a hpi baja 5sc and wen i start it it idles high and not sure wish needle to adjust if the H or L and wish direction if go left or right please help thanks and great video you got goin here by the way
Whazzup WRC. So basically left is open for more fuel and right is closed for less. You want to open(turn left) the L needle to drop revs. Complete tuning is a little more involved than that, but maybe I'll make a video about it shortly.
What do you charge to mod?
Howzit. Currently only servicing Southern Africa but we charge about $70 for porting and shipping to and fro.
What are you using for the cutting?
Dremel Tungsten Carbide 3.2mm. Round tip(not ball end) is by far my favorite but we can't get them anymore. So I use the cone shape and straight flat head. Must have those fine lines and I dip the tips in wax every couple of seconds to prevent the metal to stick in the grooves too much.
What you put on pipe in last video? Like muffler.. Diy?
Hello Saya Yo, it is rubber heat resistant deflector. It's a stock item we sell.
I have the 45cc Rovan buggy can I send it to you for you to port
Howzit Eric.
We can do that, but will you be able to arrange shipping both ways? Will make it way easier
Do you Port and Polish RC boat motors please comment back I have 3 of home that I would like to have done
Good Day Martin.
I do believe they are the same make up with different cooling.
I believe we will be able to improve them yes.
So there is no need to torque the bolts of this engine??
Some would disagree, but I say no. Just tight enough to keep the bolts in. The case 8s made from pot metal so you can strip the thread too.
@@EZR that explains why I can’t find the spec sheet anywhere. I’m attempting my first build in the 1/5 scale scene. Turning my 30.4cc (30cc) redcat rampage xt into a 32cc. I also have a 45cc but can’t find a pipe that will work with that motor and work with my platform. Probably gonna end up ripping a 45cc header off and adapting it to another pipe. Thanks for the info
@@mrskunk697 @Mr Skunk the 45cc is a tricky one yes, especially in non Baja/Losi's. Just note that a 30cc to 32cc rebuild is a complete core swop out. You cannot use the same Cylinder, Crank Case, Piston, Crank. Everything else should fit. Chat to RC Dungeon about your 45cc. He might have already found a solution to the problem.
@@EZR yep I got the new case,crank, cylinder, piston and everything else needed coming. Just need to swap flywheel then the outter case’s. Weirdly this truck came with a tuned 32cc exhaust on a 30cc not sure if that really matter but might be the reason it blew. Previous owner ran it lean also piston looks brand new except for the gouges that the wrist pin bearing caused
Great video. Did you adjust the intake and exhaust port timing?
No I didnt, but dropping the cylinder without a gasket makes some difference.
When increasing compression do u think it's better to eliminate the head gasket, base gasket, or both?
Just discovered your channel, Great work man! will u try and continue to grow channel in 2023?
@@romper4444 He does remove the base gasket to increase the compression.
you had no issues using regular gaskets instead of teflon ones? and also what carb you using?
Performance Rc telling n gaskets when over tightened. Deform then leak
Most guys won’t use them for that reason. Using regular gaskets. Cleaning mating area. Works just fine bro
Use 990. 997 or 1107 walbro carb
668 carb is used up to 30cc
Well stock Rovna gaskets are good for one time use. Best carb is the 813/990 Walbro
Make a third transfer on the intake and put a reed valve on it
How do I make a 3rd transfer
That is so easy to stuff up if you cut wrong. We'll leave it to the pros.
So what kinda power increase do you suppose you gain after doing that job. Say you had a 5hp motor starting out what you think it has now?
5.2 lol
There are a lot of factors to take into account, but the bigger the motor the bigger the increase. Simple porting will mainly increase RPM's with some torque change due to the increased compression, but changing the port timing will make a huge difference. Check out our new videos, Lots of porting stuff coming.
Typically from experience you see 1/4 to 1/2hp on a standard 29 to 32cc motor. The peak hp may not change much, people get to caught up in that peak number. Its more about how much more power is created "under the curve", so basically the way the torque comes on, the snappyness of it, builds rpm quicker and makes more torque starting at 8k to 10k to 12k to 14k and so on. Basically the motor will feel like a tuned race motor after vs a doggy stock motor. Hope that helps explain.
Do YOU offer this to the public?
OR sell an entire engine already done?
We do sell these and have started with the new 34cc that has more torque. Still a bit of a struggle to get the stuff exported though.
Hi sir help me plz , how i open hpi baja engine case side black color plastick cover/ruber ? Plz help me sir !
Sorry man. Will get some more tutorials out there soon
Probably lightening the piston did the most. You could probably shave the head by a few mills to get more compression. I wonder if lightening the crank is worth it?
Will do a before and after video soon. I dont think lightening the crank is good because the motor needs the weight momentum for the torque. It will give better RPM but will lose KW.
Got a few videos that needs editing and just not getting to it. We actually did a 63mph / 106kmh run a ferw weeks ago that I want to get uploaded.
U dont need to shave the head. They make down to .005 copper head gaskets if that's what u wish to do. Factory squish clearance is only .02-.025 and stock gasket is .02 thick so if u drop to .005 gasket from a .02 gasket ur piston only has .005-.01 of clearance to the squish band.
Also they make stuffer cranks where the crank is machined out and then stuffed with Teflon in those areas to make it lighter. And it's quite a bit of material removed and still idles just fine.
Lighten the flyweel. This will give you 0,5-1,0 hp . The engine spins faster up and gets more rpm .
@@h-jg7730 ain't no way it's giving u that kind of power. Gives u a little better throttle response, a little more snappy out the gate, thats about it.
Excellent video! Turbo port should be on intake side though. A lot of good information here. I'm a Big fan. -Perkins
Hello Perkins! How come on the intake side? The spin of the crank is towards the exhaust port where the volume of air/gas gets taken in.
Because you want to pull it out of the cases up through the transfer ports into eyebrows.
@@Perkins.porting What happens if you do both sides? One lets more in and the other lets it out easier?
That's an option, was commonly found in oldschool g230rc goped porting. In my personal experience, I didn't like the effects of both sides done. Both sides kinda canceled each other out.
I wouldn't get caught up on case porting so much... port shape, timing duration, flow porting, can have much more noticeable effects.
@@Perkins.porting Yeah I hear you. I still need to do some schooling on the timing duration side. I know that makes a big difference. But we will get there soon.
Hi mate I'm having trouble with my engine you know where the clutch plate bolts onto the crankshaft its supposed to be a friction fit and a retaining bolt in the centre but my engine is just spinning inside the clutch plate no matter how tight I put it hope this makes sense hope you can help
Makes sense, thanks for the Q. We have this with our high torque motors and what I do when assembling is place 2 drops of lock tight on the shaft before fitting the clutch mount.
You must also note that the clutch mount is a very soft metal and can be misshaped, hence it not gripping and replacing it might be the best fix.
Overall a cheap fix but can be so frustrating.
@@EZR thankyou for the reply mate I've ordered a new vented billet alloy one and I'll add a bit of lock tight on assembly thank you again
How do u do the break in procedures after a new rebuilt motor?
Howzit bud. There are different opinions. Feel free to check out our video on full break in too.
Ill give you three opinions.
#1 Text Book Procedure(what I would do with a customers car): Idle motor for 20min and cool to the touch x3; run the next 30min on no more than half throttle; 2nd tank possible to give full throttle bursts but dont over do it; 3rd tank change plug and start tuning for peak performance.
#2 My procedure(ON MY OWN MOTORS ONLY): Idle motor for 20min. Cool down completely cold. Check cylinder and exhaust bolts and then let the motor have it. Full throttle, peak tuning, take it to race day etc....
#3 Break in doesn't matter. 2stroke motors are very strong and as long as you use proper fully synthetic 2T oil at the right ratio you have no worries.
@@EZR are you familiar with the idea or theory that a slow break in actually isn't the best way to extract max power from a ringed 2 stroke engine?(not nitro pinch type engine)
Its based around the theory(well actually proof) that u got about 20m of runtime before that fresh abrasive cross hatch pattern starts to become smoother and if you don't use that initial abrasion to seat the rings quickly with varying medium throttle aggression and rpm that you sacrifice compression and power for the "safe break in" method. Everything will still run just fine the "normal" way, just what ur giving up in long term hrs before rebuild and max power. You know the old saying break it in how you want it to run from the muscle car days? Well there's a whole lotta truth to it.
There's an excellent website from a former pro racing team dirt bike mechanic that's recorded his findings over 20yrs showing the difference in engines broken in like this vs the "manufacturers way"(the break-in for dummies way lol). It is super interesting! And the results are hard to ignore when they are staring you in the face persay lol.
Yes, our new way is more fun friendly. 5min on the bench and then give it stick
HELLO THERE I LIKE YOUR BAJA STAND DID YOU BUILD IT YOUR SELF NEED ONE LIKE THAT
Hello Leo, actually a customer did it for us. Difficult to get nice working ones that is not too pricey.
.. From Italy, you're a great mechanic,but After this the affidability Is the Same??..
Hello. Thank you.
Do you mean is the reliability the same or if the cost is the same? 🙂
hello, congratulations on the video. I recently bought a model with an engine similar to this one (MK T2000 4WD), but the engine does not work. I touched the candle, removed the filter, put gasoline (500ml gasoline x 20 ml oil 2 stroke), but it didn't work. Please can you help me ?
Hello, thanks for reaching out!
#1 is ring & sleeve. If those are badly worn nothing will happen.
Our first check is Coil gap and Spark plug.
I do think we need to do a video on this. Hope to get to it soon.
If you reset your coil gap and changed the plug with no joy then you need to check if the carb is actually fueling the motor. With the filter off - Is the inside of the carb actually getting wet when you choke it?
If it is - the piston ring is your next check. You will see the problem sure enough with these checks.
@@EZR thank you very much for taking the time to answer my questions. I live in Japan, and there is not so much information about this here. I will do what you told me. thanks
The big question is what's the price on a full porting job if I buy the motor from you.
Good Day. We are based in South African and currently offer a full port on a 32/34/36/45 @ $90/ZAR1500
We are looking at exporting in the near future.
Can I send you my motor and you port it completely and I want a 32cc head on it?
@@EZR hey man, how much to port a gp 460 motor for a goped ?
@@reptile0074 our porting costs $80 for a cylinder full mod. But our hurdle is the shipping. Still trying to jump that one.
How much more power do u get frm that. Very cool shit. Thanks for posting man
It mainly ups the RPMs but the head drop and exhaust opening helps with some torque. If you can get your port timings right you can squeeze a lot of juice out if a little CC.
You should dyno the engine before modifying it, then re-test it after the porting. Only then can you (and the paying customer) can see where his money went. Do you sell the tuned pipe that was on the engine at the end of the video?
Try daves discount motors usa. But try ebay for the chinese clone copy. Just as good as the dominator. After racing theese things ive found the 26cc barrel with a dominator the best combo. But stay away from the 813 carby
Good Day Christopher. At this point in time we are not a pro as OBR or ESP and hence charging less than half their prices. We do not dyno as yet, but try to improve response and RPM without effecting reliability.
That pipe is a Rovan Dominator Gen 1 and will out perform the DDM pipe at double the price.
Our fav is still the KM Ruler Pro Pipe.
Most of our cars run the 813. Wins most races in South Africa at the moment.
@@EZR hii. Nice video, damn good explain. I advice you to try carb 1107 on that 32cc
Look at my channel, its based on your instruction. Many thanks. Will follow your videos.
Advances exaust opening by cutting piston crown....?!?!
Yup. Doesn't work on all motors but ups the revs on the Rovan 32 head that gets dropped. If you not gonna drop the head. Don't cut the piston crown.
.must be re-rodate the piston and cylinder again??....
Sorry Re-what? :-)
@@EZR first period of new parts ..piston,cilinder ..must be caefully..x not damage the internal surfaces.. understand me now..?!!?..😉
Very nice work bruh where are you located?
Thanks bud, I'm in sunny South Africa, Gauteng.
@@EZR wow way too far away nice work though
U should of put a window on the piston
I've seen some guys do that but I just have not played around with that idea enough. Why don't the big boys like OBR do it?
That reminds me of a chainsaw motor.
Yeah they are very similar. These Rev higher with less torque.

Hi my name is Larry d9 you port motors for people i need one done
Yes we do porting. Unfortunately only in South Africa at the moment.
Yes we do porting. Unfortunately only in South Africa at the moment.
Eh, my 36cc probably still has more power than a ported 32.
there is no replacement for displacement.
Probably not.
No it has not ! even a good moded 29 or allredy a 26 will eat Up your original 36 for breakfast and shit it out :))
Lol your roven 36 cc is garbage u never seen zenoah 32cc it got double power ps i mod engine better than this guy
those 36cc engine might be big, but dont rev hard unfortunatly
a decent 29 or even well build 26/27cc engine will chop u up on the track,, they spin harder, go faster
waste of time and money unless your putting it in a boat.
