The only thing I can really say after running mine is that the stock exhaust has to go if you do buy a better carb. While running a larger really expensive carb I did notice that I got better performance but it wasn't great because more fuel in means a better exhaust is needed to get the burned and spent fuel out.
Hydraulic ebike brake kits are a great upgrade as the tectro's are meant for higher speeds and I don't replace them too often, about 500-700 miles depending on how aggressive I am with the breaking
Bro I installed one of those racing heads from Amazon on my pk80 wild cat, gained 5 more mph But engine got hot then I looked at the piston an was burnt , I also broke a strut on the cylinder bolt trying to tourqe it , now I the stock head with 3 bolts lol, going to buy new cylinder struts . An better cylinder an piston , note I tired even running rich on that head , maybe was leaking air causing it to over heat , fuel ratio did help but not enough carefully with them after market Amazon heads , I know they make one for my wild cat going to try that In the future thanks bro
What is the best way to bring down the noise or witch exhaust silencer maybe a homemade one??? I'm downtown Montreal... Bad boy wants to ride his badboy bike...
I am a new subscriber, but I appreciate your content and I saw you did everything very professional and you seem like a good guy and forget about it love the Boston accent, but if you could give me your advice on, can I get a raise and head to the only ones I can find say 66 to 80 cc will that still fit on the stock? and what brand bearings would you say are the best? If you get time, I would appreciate if you could respond to this. Thank you again appreciate your contact you have a new subscriber forever.
If u get a new carburetor like a high performance carburetor just swap the jets out from the nt carb to the new hp carb and it’s actually the balanced jet for it
If you're a gear head like me then choose your sprocket size wisely because I'll go as fast as it lets me so I took off my 32 tooth and put on a 36 tooth just so I can't go as fast
So have been riding these bikes over 10 years worst thing is the exhaust pipe vibrate sluice wears out the bolt hole just makes it louder all of a sudden I have a fast high RPM dried reducing the adjust Gable and throttle body. Help. Please. And to me coaster brake is great for stopping faster
What I'm curious about is these engines? Seems like there's not too many & the ones I see look like they are made by 1-2 Metal Foundry's over in China? So you have these choices & again as you look all these "Engine" kits are being sold to you OR "AT YOU"? So we've got to guess which "KIT" has quality parts inside or what's crap within the kit? That's a big problem after spending $300 bucks & learning that half the stuff in your kit was poor quality? How/what to buy is a major issue but after watching this I Will Know ! I have no doubt. thanks very much & peace
There are a handful of factories producing the components having different dimensions and the assembly shops will often switch who they buy from and have to add extra gaskets and such to make the engines run. Tons of garbage in the castings and it seems many have unskilled labor assembling the engines using hammers.
Thanks, while I've not dug into this that far I knew by looking that it was way below standards for other motors. I'm not looking for Rocket Science good quality but I've looked at how well made gas drone engines are made & then motorcycle engines, I'd think there'd be a little more quality as those manufacturer's compete? Guess not & I've put off buying hoping to see better stuff. Again, I appreciate your time. peace
Yes, I think I've noticed that in most the videos I've watched but you're the only that said IT To me. Most people would think that buying a "Motor" would be one closed unit that was considered "Good to Go"? Another issue is all the different things in the "Kits" you get w/ the engine. Each piece must be looked at but how would you know about these parts until you were told or had a break down? But the engine unit itself I would think was a solid unit - you're saying that once you buy one needs to have the basic tools to tear down a new motor & then rebuild it w/ parts that are stronger/better? Having to do this, & I thank you for spelling it out, defies logic to me but I do stand corrected ! So I buy an engine knowing that all of them need to be rebuilt? And how would I know which parts inside "Said Motor" were needed to be replaced? It's almost mind boggling to me & tell me if I'm stating this correct; I buy an engine knowing that I need to go thru it to put in better parts? I feel so stupid even typing this but please tell me this is the case?? Wow, so I buy an engine & I keep buying additional parts until I get something to WORK good? Hey, I do appreciate sharing this w/ me before I jumped in not knowing. I'd be at a loss because no one expects to buy something that needs to be redone before they use it? Blows my little mind, lmao. I do thank you for your time. IDKnow if I'll ever get started now but I'm not quitting yet, thanks again
Lower number = hotter. Get. A B6 plug and compare. You decide. I'd run a hotter plug inn the winter but if no improvement then no need.. Too hot can damage however one plug up should be fine
This video was how I found out my 100cc engine was just an 80cc with a big ass head on it. OOF. I wish the manufacturers wouldn't lie, it's so pointless.
There's a difference in how the Chinese calculate engine displacement (and add in some misdirection) and the way the rest of the world calculate it. That adds to the confusion. But YA, it's all over the place. There are Big Bore Kits sold for scooters to increase the displacement and many just flat out lie
I’ve got a China girl that I built 3 years ago..I had heart surgery and now rehabed and feel good...what do I do to get it running again. It’s been well kept inside of a garage all this time, I just don’t know where to start. T
I'd just rebuild the piston or slap new rings on them and port the cylinder jug also carb clean and take apart the stock carburetor, these carbs can run forever unless they physically are damaged.
A real pk80 or zeda80, make sure it's one that has 8mm mounting studs. There are a lot of cheaper older versions of china doll motors on ebay that still have the 6mm mounting bolts that break off easily. Avoid them. Also, upgrade the throttle tube assembly with a metal one, the plastic stock ones in the kits always break where the cable attaches.
If you have a reed and some serious porting mods, a true balanced crank and a fat expansion chamber then yes it would be worthy to use a 21mm carb. Prolly a decent choice. A mildly ported motor, it would be overkill as the engine can only move so much air/fuel.
Thats bull shit 2 stroke engines like full throttle. If that isnt the case then why do chainsaws and weedeaters. Foul and burn up if not kept at full throttle after warm up. 2 strokes dont mind being at full throttle
as someone who worked landscape maintenance i know that most of our tools were 2 stroke, chainsaw, trimmer, gas blower ect. and i was always under the assumption it was becasue not only the versatility of movement not having to worry about the engine staying level during operation as well as their abilitiy and optimized performance as an engine that is designed to be at full throttle for long periods of time. for example during hedge season we use gas 2 stroke hedge trimmers and run them up to 3 hours straight at sometimes comeplete full throttle. these engines operate like this 10 hours a day and these machines last 5 years or more. I always here people on the motorized bike community though say that 2 strokes dont like to be at full throttle for long peiods of time. Im curios why is this the case as most other 2 stroke engines are designed to be operated at full throttle for long periods of time, i men think about it Even lumberjacks how would they be expected to work all day if theyre always running half throttle and letting the engine cool down every hour.
It’s taken me over of year of watching videos like yours to finally indulge my inner child.

Mr hughes, thanks for share all this great information so helpful about motorized bikes,&others topic, say hhello from panama republic, joe, thanks, continuye.
Anyone curious about the death of the gentleman in Colorado should know that it was NOT the fault of the bike Hughes sold him. The reason he mentions safety and the importance of gear is because there are people that can hit you and send you flying off your bike to your doom, which is exactly what happened with the bike he sold. I could only dig up two separate incidents where a motorized biker died because they were both launched off their bikes due to impact with an SUV in 2019 and 2021 respectively. Get yourself some good brakes, wear your dang helmet, be aware of your surroundings, stay sober on the bike, and you’re good to go
Damm...that is a reality, but gives to think when it happends. Good brakes are complicated, but I already had ordered an adaptor to put the rotor brake back too.
The best description of these bikes I’ve ever heard i’d say it’s more like 60% fine 40% maintenance but that’s probably me just being lazy and letting my engines blow out
Dangit.I subbed to you around this time as you made sense out of all the ..stuff...being said about these.>Obviously this is 3 Years later.(Thnx YT). I did my plugs by Your scale and the engine did Great.Thank You.Never screwed with 'jetting'.I took a punch and tapped in the hole a Tiny bit as the plug was wet.Fixed it.Tan plug .(I checked before and after with 'torch cleaning' kit wires,and went down a hair)
G,day Eugene. I’m just wondering what Dremel attachments do you use when your porting out the intake and exhaust outlet please. Are they the orange and green coloured carbide bits or steel milling bits. I just brought a Dremel, I’m not used to what the attachments do. Thank you for your help I appreciate it mate. Take care buddy.👍
The key to going fast with small displacement engines is the fuel. I was able to go 50mph on 49cc two stroke engine using 110 octane trick fuel in 1977. I figured it out when I was 16 years old. It’s not complicated 🏁🏁🏁
I made a case reed lower between them two case bolts I didn’t want to not have them bolts. I tapped the holes for the reed valve to 6mm thread. I am going to make a bracket for the carb so the reed bolts don’t take the load of the carb.
Just had to order a magneto seal for my baby bee today, hopefully I don't end up having to change anything else for a while, except for maybe a new flex exhaust with the expansion chamber. A little less effective than the fat belly, but Itll look great and should work better than the stock for my beach cruiser setup
I'm sorry about the kid in Colorado, even though that's not your fault you must still feel some kind of way about it. It's like this, if you've never ridden a bike at high speeds and felt how easy it is to lose control you probably wouldn't want to be much faster than 35mph anyways. Been 30 mph on a 16inch bike, terrifying lol!
My bicycle engine dosnt use a mix fuel. It had a designated oil containing and a separate gas container. That let's me run nitrometh from time to time along with the very occasiona No² bottle and boost bottle. My record on a 50cc is 82mph. On a bicycle that's fucking scary as hell lol
I purchased a bbr stage 4 high compression head this is my first time building a bicycle engine kit I put the head on between the head and The jug I can still see the copper gasket and the head bolts there's a gap but it looks like it's sealed I have two gaskets at the bottom of my jug I don't know if this is normal is there supposed to be a small Gap I'm confused about it if you could help in any way I'd appreciate it thank you
I live about 2500' in elevation. I took my Phantom 85 V3 out for a test spin. Runs great but after awhile about 2-3 miles, it wants to bog down and cut off. That is because it's too rich, right? I've got jets from 65 up to 70. What jet size do you think is best for my elevation?
If it runs worse after a few miles then I'd suspect the coil or CDI going bad. next, I'd look to see if the gas tank is venting properly. might be starving for gas
I ordered a banana exhaust for 20 bucks on ebay. I wonder if that will up my power? I noticed the exhaust and muffler that came with it was pretty lame.
Good Morning Do you have any suggestions or thoughts for a exhaust pipe. I have a GX7 29.. The high compression head won’t allow a bolt on.. The banana pipe won’t clear the front wheel... SBP ES02 is not available.. Do you have any suggestions or do you have one you can sell me??? I’m in Cleveland Ohio...
Hi, I'm from South Africa, happy to have discovered your channel. I use my bike for fishing and tow a trailer, i sometimes find it difficult to start the motor by pedaling, i wish to fit a pull start, our local guys say the pull starts is crap and don't recomend it. What is your experience and can you recomend one that won't break the bank? Looking forward to hear from you.
Hi Eugene, i’ve been looking at purchasing another 80cc kit. However I’ve looked and a couple of different models and the specs of the motor are exactly the same (identical) but the maximum speeds are about 10kph difference. Why would that be is there a speed limiter on these motors? If not am I able to increase the speed with my racing head and racing carburettor that I have. Thanks very much. Take care buddy.👍
Expect 40-51kph on average. A poorly balanced engine might get less. An engine with less trash in the ports and a better balanced crank might get closer to 60kph. No, there isn't a limiter per se, but the limits are manufacturing variables / defects
i respect THE Men here.. Hughe.. the thing he said about the carburetor is so F true after 3 years (quarantine get me in to the hobby) i spent money in every carburetor i saw people use on the internet and every time i when back to the NT there is no way around on a china doll motor (just a porting to take the lips out of the intake and exust maybe but just that nothing else) keep your NT on people
Thank you so much. Anyways, I’m 14 and I nearly got killed doing 35 on my motorized bike thank god I literally got no broken bones or anything. Just very minor bruises
if they had an awards night for best teacher of motorbikes you'd win 1st in every category. ive been bu io ling these bikes for a yr n a half. im still learning. i buy bikes that ppl have no idea how to fix em,so i grab them for $100 bux or less. i sand ,primer, paint,clear coat,rebearing,and grease,put togather from birth to re pairing of or replacing the motor and flip them for 350 to 500 . but i learn from you hughes. your an award winning teacher. ken.new port richey,fl
Im brand new to this hobby, your channel is awesome!! I subbed instantly. So im not really concerned with breaking the sound barrier. 35 to 40mph is perfect. I live in Pennsylvania (Johnstown Pa) i was given by my buddy a BBR 80CC, It runs good. It has the 3 prong plug and he was running 16:1. Whats your recommendation on the mix and plug i should use?? Thank you for any help
What make a Float get hold in it I can't get my bike to go long enough to run more than one time and not very far next time I try to run it flot is fool of gas no one sale just the flot sorry for the spelling
I had a question, I don't see a reed valve on here, would it be worth investing in a reed valve kit for an 80cc and windowing out a piston to get better performance? Provided I did these 6 things on top of that first.
NT is the best other than a True Dellorto. The "HP" is a cheap ripoff. No real magic carb. Balancing, porting, port timing, proper expansion chamber, and jetting is what will make these motors run best. Once you have all that work in a 50cc Morini or KTM engine will be far better, cheaper, and more reliable
@@HughesMotorized a stock kit from ebay dynos at 1.5hp without the air filter cover adds .5hp then jet matching adds a ton it just shows its not a very refined carburator
I’ve been running 40:1 for years and years in just about every 2 stroke engine I’ve had and I’ve never had any issues with it not oiling properly or wearing out prematurely!!! Infact it’s more than good enough!!!! The thing most people don’t understand is that 2 stroke motors are happier in the high rpms and they don’t like idling too much!!!! You end up with fouled plugs and clogged spark arrestors when you constantly run a 2 stroke engine in the lower rpm range…
My first bike build I was in it off the start. Wide open all day. It never failed .. sold it eventually but it was the most fun bike I'd had to this day.
Thanks for this great video! I’m getting an engine kit tomorrow, I have 2 stroke synthetic oil. The engine has not been used at all. Should I go 16:1 during break in. I’m confused on why everyone keeps saying 16:1, then some people say 20 or 30. Then you say 40. Thanks!
I don’t necessarily want a turbo busa bicycle reincarnate. I just want it to run efficiently and be able to get over steeper bridges and viaducts + sound good
Hey Joe can you possibly do something on a 47cc pocket bike off-road atv motor install on mountain or bmx style bike plus rear sprocket options / install been waiting on motor 3/4 weeks it's actually 12days late today but anyway it would be helpful and appreciated on build
I i wished to take my 80 cc 2 stroke motorand put better bearing in what would i install i already have a high performance pipe and this week i will work on porting the intake and exhaust ill probably will b e changing the jetting im sure ive learned alor from u THANKS

It's a matching thing like you say. best carb ever wont help if you have a crappy exhaust and or bad porting
All I can say is yes and no to your comment there are so many variables and no Motors are the same
Hydraulic ebike brake kits are a great upgrade as the tectro's are meant for higher speeds and I don't replace them too often, about 500-700 miles depending on how aggressive I am with the breaking

The reason he mentions safety and the importance of gear is because there are people that can hit you and send you flying off your bike to your doom, which is exactly what happened with the bike he sold. I could only dig up two separate incidents where a motorized biker died because they were both launched off their bikes due to impact with an SUV in 2019 and 2021 respectively.
Get yourself some good brakes, wear your dang helmet, be aware of your surroundings, stay sober on the bike, and you’re good to go
Damm...that is a reality, but gives to think when it happends. Good brakes are complicated, but I already had ordered an adaptor to put the rotor brake back too.
Really dig your videos! I have a 26 in. Haro mtb. W/ a Zeda motor. Lovin' this hobby! 50% fun 50% maintenance!
Right on!
The best description of these bikes I’ve ever heard i’d say it’s more like 60% fine 40% maintenance but that’s probably me just being lazy and letting my engines blow out
Dangit.I subbed to you around this time as you made sense out of all the ..stuff...being said about these.>Obviously this is 3 Years later.(Thnx YT). I did my plugs by Your scale and the engine did Great.Thank You.Never screwed with 'jetting'.I took a punch and tapped in the hole a Tiny bit as the plug was wet.Fixed it.Tan plug .(I checked before and after with 'torch cleaning' kit wires,and went down a hair)
G,day Eugene. I’m just wondering what Dremel attachments do you use when your porting out the intake and exhaust outlet please. Are they the orange and green coloured carbide bits or steel milling bits. I just brought a Dremel, I’m not used to what the attachments do. Thank you for your help I appreciate it mate. Take care buddy.👍
Carbide bits are best:
Vaccum Base Vise - amzn.to/3ct7Tr9
Carbide Bits - amzn.to/2MmZT05
Polishing Bits- amzn.to/3gXvFyW
Grinder w/ Flex Shaft - ebay.to/3drY1iF
The key to going fast with small displacement engines is the fuel. I was able to go 50mph on 49cc two stroke engine using 110 octane trick fuel in 1977. I figured it out when I was 16 years old. It’s not complicated 🏁🏁🏁
That's only gonna work if you have the compression to back it up
I made a case reed lower between them two case bolts I didn’t want to not have them bolts. I tapped the holes for the reed valve to 6mm thread. I am going to make a bracket for the carb so the reed bolts don’t take the load of the carb.
Just had to order a magneto seal for my baby bee today, hopefully I don't end up having to change anything else for a while, except for maybe a new flex exhaust with the expansion chamber. A little less effective than the fat belly, but Itll look great and should work better than the stock for my beach cruiser setup
I'm sorry about the kid in Colorado, even though that's not your fault you must still feel some kind of way about it. It's like this, if you've never ridden a bike at high speeds and felt how easy it is to lose control you probably wouldn't want to be much faster than 35mph anyways. Been 30 mph on a 16inch bike, terrifying lol!
Fine job... you always have really good Info to share and it's much appreciated.
Great information. Building my 3rd and never knew any of this. But on the the carb jets, it's the first set that comes up? Or?
My bicycle engine dosnt use a mix fuel. It had a designated oil containing and a separate gas container. That let's me run nitrometh from time to time along with the very occasiona No² bottle and boost bottle. My record on a 50cc is 82mph. On a bicycle that's fucking scary as hell lol
I purchased a bbr stage 4 high compression head this is my first time building a bicycle engine kit I put the head on between the head and The jug I can still see the copper gasket and the head bolts there's a gap but it looks like it's sealed I have two gaskets at the bottom of my jug I don't know if this is normal is there supposed to be a small Gap I'm confused about it if you could help in any way I'd appreciate it thank you
here 125cc 2t makes from 60-80 hp and this dude talks about stock carb and some jetting
Top video!
Dude 1:17 that is definitly what I do!! This is one of my favorite motorized bicycle videos and channels!!!
I have an idea for ya. A video showing an engine stand build like you have in this video. I think an engine stand is something we all could use.
Might do that when I get the time. Good idea. Thank you
I live about 2500' in elevation. I took my Phantom 85 V3 out for a test spin. Runs great but after awhile about 2-3 miles, it wants to bog down and cut off. That is because it's too rich, right? I've got jets from 65 up to 70. What jet size do you think is best for my elevation?
If it runs worse after a few miles then I'd suspect the coil or CDI going bad. next, I'd look to see if the gas tank is venting properly. might be starving for gas
I ordered a banana exhaust for 20 bucks on ebay. I wonder if that will up my power? I noticed the exhaust and muffler that came with it was pretty lame.
Needs a smaller jet from stock. #66
I need a good high performance cdi like you suggest but my motor is a duel plug setup, any suggestions
You want the best, wanna the fastest, you will burn dough at the altar of speed.
Good Morning Do you have any suggestions or thoughts for a exhaust pipe. I have a GX7 29.. The high compression head won’t allow a bolt on.. The banana pipe won’t clear the front wheel... SBP ES02 is not available.. Do you have any suggestions or do you have one you can sell me??? I’m in Cleveland Ohio...
Shoot me some pics of a pipe held in place. hughesmotorized@gmail.com
Hi, I'm from South Africa, happy to have discovered your channel. I use my bike for fishing and tow a trailer, i sometimes find it difficult to start the motor by pedaling, i wish to fit a pull start, our local guys say the pull starts is crap and don't recomend it. What is your experience and can you recomend one that won't break the bank? Looking forward to hear from you.
The pull start for these 2 strokes is garbage. They break early and often
@@HughesMotorized thanks for your response, appreciated.
Hi Eugene, i’ve been looking at purchasing another 80cc kit. However I’ve looked and a couple of different models and the specs of the motor are exactly the same (identical) but the maximum speeds are about 10kph difference. Why would that be is there a speed limiter on these motors? If not am I able to increase the speed with my racing head and racing carburettor that I have. Thanks very much. Take care buddy.👍
Expect 40-51kph on average. A poorly balanced engine might get less. An engine with less trash in the ports and a better balanced crank might get closer to 60kph. No, there isn't a limiter per se, but the limits are manufacturing variables / defects
For the average person a chain saw carb is the way to go
i respect THE Men here.. Hughe.. the thing he said about the carburetor is so F true after 3 years (quarantine get me in to the hobby) i spent money in every carburetor i saw people use on the internet and every time i when back to the NT there is no way around on a china doll motor (just a porting to take the lips out of the intake and exust maybe but just that nothing else) keep your NT on people
Preach!
Very knowledgeable! I have a question about skirting the piston on the intake side. Does that actually help?
Ride it like you stole it! ...dress for the crash, not for the ride...
first good explanation ive found for the carb assembly! thanks for the encouragement to take the 30$ carb off my shopping list LOL
Glad it helped!
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,thanks.............................................
Love your channel, Love you man. From UK
Much appreciated!
You still have carburetors for sale? need one for a 100cc
Thank you so much. Anyways, I’m 14 and I nearly got killed doing 35 on my motorized bike thank god I literally got no broken bones or anything. Just very minor bruises
TEARING ASS THRU THE NEIGHBORHOOD… hell yeah
if they had an awards night for best teacher of motorbikes you'd win 1st in every category. ive been bu io ling these bikes for a yr n a half. im still learning. i buy bikes that ppl have no idea how to fix em,so i grab them for $100 bux or less. i sand ,primer, paint,clear coat,rebearing,and grease,put togather from birth to re pairing of or replacing the motor and flip them for 350 to 500 . but i learn from you hughes. your an award winning teacher. ken.new port richey,fl
aww shucks, thanks
plsssss tell me you know were i find jeting for the bofeng carb? thx and good work
Here you go amzn.to/49hd5vI
Im brand new to this hobby, your channel is awesome!! I subbed instantly. So im not really concerned with breaking the sound barrier. 35 to 40mph is perfect. I live in Pennsylvania (Johnstown Pa) i was given by my buddy a BBR 80CC, It runs good. It has the 3 prong plug and he was running 16:1. Whats your recommendation on the mix and plug i should use?? Thank you for any help
40:1...3.2 oz oil per gallon. You'll stop fouling plugs. Get an NGK-B6
@@HughesMotorized Awesome thank you so much
Can I add a high preference head on a 100cc motorized bike and what is the best spark plug for it
those are a one piece head and jug. Cannot swap the head out
What make a Float get hold in it I can't get my bike to go long enough to run more than one time and not very far next time I try to run it flot is fool of gas no one sale just the flot sorry for the spelling
Best off getting a new carb: ebay.us/TJnhJ9
I made a bike and the boy is dead lol listen to me ha ha funny
Silly dude, you’re awesome
I had a question, I don't see a reed valve on here, would it be worth investing in a reed valve kit for an 80cc and windowing out a piston to get better performance? Provided I did these 6 things on top of that first.
How should I set the gap on the NGK plug?
I know the hp carburator is decent but im looking for something alittle better could you do a review on carburators?
NT is the best other than a True Dellorto. The "HP" is a cheap ripoff. No real magic carb. Balancing, porting, port timing, proper expansion chamber, and jetting is what will make these motors run best. Once you have all that work in a 50cc Morini or KTM engine will be far better, cheaper, and more reliable
@@HughesMotorized a stock kit from ebay dynos at 1.5hp without the air filter cover adds .5hp then jet matching adds a ton it just shows its not a very refined carburator
Extra oil can help seal the combustion chamber to make more power.
Extra oil also leaves extra carbon. That carbon is abrasive and can accelerate wear
I like his videos. These are probably the best sets of videos. General knowledge
I’ve been running 40:1 for years and years in just about every 2 stroke engine I’ve had and I’ve never had any issues with it not oiling properly or wearing out prematurely!!! Infact it’s more than good enough!!!! The thing most people don’t understand is that 2 stroke motors are happier in the high rpms and they don’t like idling too much!!!! You end up with fouled plugs and clogged spark arrestors when you constantly run a 2 stroke engine in the lower rpm range…
My first bike build I was in it off the start. Wide open all day. It never failed .. sold it eventually but it was the most fun bike I'd had to this day.
Thanks for this great video! I’m getting an engine kit tomorrow, I have 2 stroke synthetic oil. The engine has not been used at all. Should I go 16:1 during break in. I’m confused on why everyone keeps saying 16:1, then some people say 20 or 30. Then you say 40. Thanks!
Go to HW store and get cheap 2 cycle oil. Mix 40:1 from the start. After you run 1 gallon thru then use the synthetic if you want
Hughes Motorized Great thanks!
16:1 break in period (2 tanks which is also one gallon)
So after 1 gallon, slowly go 40:1 doing a plug check to see how rich you're burning.
*I dont want to go 45+MPH on a Bicycle. TBH anything over 25-30 Is getting dangerous they aren't made to handle those high speeds*
amen
I don’t necessarily want a turbo busa bicycle reincarnate. I just want it to run efficiently and be able to get over steeper bridges and viaducts + sound good
Hey Joe can you possibly do something on a 47cc pocket bike off-road atv motor install on mountain or bmx style bike plus rear sprocket options / install been waiting on motor 3/4 weeks it's actually 12days late today but anyway it would be helpful and appreciated on build
I i wished to take my 80 cc 2 stroke motorand put better bearing in what would i install i already have a high performance pipe and this week i will work on porting the intake and exhaust ill probably will b e changing the jetting im sure ive learned alor from u THANKS
