Why am I now just seeing this video, its 3 years old! Anyways thanks Alex for taking the time to make the video, getting the motorized bicycle community hip. ☺️
I love your boy-like excitement and enthusiasm! I felt the same way when I opened mine! That is a pretty motor! Thanks sincerely for this video. Good luck to you!
Definitely a solid motor,, I bought mine last June and it's going strong,, I swapped and modded a Jog50 pipe, a tuning carb on it, it's got easy over 2000miles on it, 36tooth on 38:1 premium gas and its boneass stock inside
And for you people bashing his channel it’s a lot harder than it looks to make these videos and keep them entertaining I personally think he does a great job and has an awesome channel
good engine guys ; you get an engine that starts right up. it has the authentic bogging sound but only until you get it to the whopping 18 mph if the chain tensoner holds or the plug doesnt foul or the cdi doesnt get scared and bitch out.
If you sand and linseed oil your nice wooden bench it will darken, allowing objects on it to compete with less light and it will resist staining a little more.
I'm from brazil and this kind of unified heads when arrived here showed pretty bad, that model vibrates a lot and doesnt hang much stress when u pull full the throttle,at end this ones looks like they works with even lower RPMs than the common heads and cylinder ones, but would be nice if u can take and make a review riding and after opening to see whats gets spend inside sorry for my english lol
Some people got nothing better to do than to criticize people at least he's doing something, bro keep it up am about to start building motor bikes for my team may God bless your work bro my name is Antonio aka Tony
I'm glad you did this video! I'm a machinist. I was and have been looking at making a V-Twin out of of the 50 and 80cc engines. But this 100 looks like it has more beef to work with. Now I have to order two!! I will make a billet case for the twin. Lots of development I'm headed for. I'll send you a video when I'm done!
I'd like to see that too. Gonna be difficult with a 2 stroke since each cylinder will require it's own crank case as the crank case is part of the intake and is pressurized as the piston travels down in it's cylinder. Crazier things have been done and something like this should be pretty interesting.
@@silas__modz4020 I'm talking about ready-to-buy kits, not really modded stuff. The only engines that have dominated the market so far is the 66cc china girl, the electric start BT80, and the 49cc Huasheng 4 strokes. There's finally a new engine, even if it's still borrowing most of the china girl design
Dang that is cool it came straight from JLZeda China. Yes please.. when you get it mounted up and running do like your opinions review on it. Looks like a great Engine. Congratz on your 10K subs. You're one of the better Motor Bike builders out here... my opinion.
Great videos Alex. You should come run that BT100 in the 5th Annual Midwest Scarecrow Run...a 65 mile Motorized Bicycle ride taking place June 8, 2019. This event is just west of Peoria Illinois. We have had riders come from Bloomington IL, East Peoria, Iowa, Colorado, Missouri, Conneticut, Oklahoma, Michigan, etc. The ride host some cool bikes and cool people. You would feel right at home.
I've heard about this ride an wish I could bring my bikes to ride in that event.im on Facebook Bikelife flying motorbikes page.all are welcome to join.
Just as well the older two strokes had three ring Pistons of course they're all compression rings it just lasts longer because the Piston will not slap as much. There is a racing piston with a dykes one ring that doesn't last very long but the ring expands with RPM and compression but it doesn't last very long.. apples and oranges on the 4-stroke suggestion we all know about the oil ring on a 4-stroke has nothing to do with the two stroke 3 ring piston apples and oranges
I just love those little engines. Can’t wait to see it run. I’m thinking the price point is a little high. Around 200 would be good If everything checks out. I’m really interested in seeing it mounted and tested.
Sorry for you...... I bought ONE 66cc gasket engine kit. This I use as patterns for thew gaskets that I make. So, now I make all my gaskets. Head Gaskets I make from .012 thick aluminum sheet and .011 copper sheet. exhaust and carb gaskets I used just regular Automotive Exhaust Manifold Gasket material. 8x11 sheet about $10, I can make 20-25 out of that sheet. One advantage of making your own gaskets is that you can port match Intake and exhaust ports for a smoother flow.
It's been like three weeks and nobody has done a review video on this engine. I'm dying here. Hook us up with a review! I'm eager to know if I should buy it or not. Thanks for the info and your channel rocks!

Doesn't look that great tbh. If it's the exact same price as a normal stock kit, then maybe it's worth it. But that head being oriented the wrong way (and the fact that that's unfixable since it's a one piece head/jug), needing to have a super long allen wrench, and needing to buy certain custom parts like the gaskets. I see a lot of these blowing up due to overheating. One of the coolest upgrades are custom heads, which you can't do with this at all. Skip.
Jeeze, custom heads are dead easy, you just mount on a mandrel and turn the old head off. Could probably be done on a mill but I would use a lathe. Sthil have used 'long Allen key' design for one piece since before I started working on them in 1990. Your just too cheap for words, buy some decent tools if your going top play with engines
@@peterjones6945 I'm sorry what?? How can you say it's dead easy then tell me I require a fucking lathe or a mandrel or a mill?! You know what most engines require for new heads? A socket wrench. Even top notch engines. GTFO of here
@Yard Sale Dale Why mill?? Then wtf are you supposed to do?? I'm saying if I want to buy an aftermarket head for this I CAN'T. Solely because the head is attached to the cylinder.
Thanks for everything you do Alex. I just started my 3rd build. looking forward to seeing the bt100 on a bike don't know why the fins are cross ways hopefully she doesn't get too hot
I ordered one of those little no-name Chinese 2-stroke engines but unfortunately, it arrived without a very crucial part. I went back through all of the boxes and couldn't find it. Then I thought that it could have gotten into the engine itself while being shipped out from the other side of the World so I, very calmly, disassembled the engine and again, couldn't find
@@HighMileageOffroad but first, its still an upgrade, even if IT doesnt do much, and there's no other upgrades for a bike engine kit i know other that the ones i already wrote about
It'll flat- line a little after mid-range power hits... porting should stretch it's top speed a little. It's nice but only for good bottom end power. Though I could be wrong because it does seem to have a shorter rod.
I noticed inside the head that the spark plug threads material bunched up could cause detonation issues. I would dress or up with a carbide dies grinder bit and smooth it out.
Sure looks pretty good don't it I wonder if they upgraded to a stiffer clutch shaft spring 🤔 I'll definitely try to get one later on but in the meantime I want to see you rip this thing hard lol 🚲💨💨💨 Also congrats on the 10K subscribers! 👏
I am not familiar with the bolt on motor market but if this is typical of whats on offer then they have a ways to go to catch up to current 2 stroke tech you could put this in a 1950s motorcycle and it would not look out of place so I am assuming they are going to be cheap as chips.
Try taking it apart and putting it back together to see the components inside and then make a test run video but off the back I wouldn't spend no 280 for that like you said I would expect a starter
I could do without the starter if it had a 2 ring piston a cast iron liner and a removable head. this variation they are casting now is a total engineering joke.
I didnt have that kind of priviledge. Instead I started learning about engines 2 to 3 weeks ago reading and watching videos and looking at diagrams on my phone xD
As long as the cooling is kept in check for the MODERATE (not full out performance driver) the thing should do alright. Larger piston, more CCs and further out of bounds there legally in most places still though. I'm a four stroke guy myself. My bike was built for utility over performance.
Oh you will also need to make the main jet larger by total area the jet you are using times the pressure boost as atmospheres this not easy to do but you can read about the processes for doing this if you think that what I had written was long then you will need to take time to study jetting and engine for the first time. Tip: The engine will surge like it is missing that is the symptoms of too low of fuel in the cylinder which means that you will and must do fuel enrichment processes. It may blog-out just before you start to scream again you need to do fuel enrichment processes. First, check the sparkplug(s) this should be almost brownish in color (colour) but with these symptoms, the sparkplug(s) will be starch white this is the time to study fuel enrichment processes. It will be really worth it time. If the engine just starts to go then lags back you will enrich the fuel mix SECOND TIP: Get the jet flow area and multiply it by 1.5 this will equal the new first step now find the new diameter go get a drill of that diameter and hand drill the hole do not use a power drill ever while doing these drilling process use tape that sticks very well wrap it around the back end of the bit use your own fingers to power the drill bit through the jet for however many cylinders that there are then install and test. you will be doing more drilling on these jets very shortly again just keep making them larger step by step get more drills sizes. SEE the fact that you have done the other work correctly is why the carburetor just can not supply a rich enough fuel mixture the ait is passing through the carb so fast that it just can not supply the fuel for it. A word to be noticed is if you can not get it to enrichen the mixture enough after drilling out the jets four or five times through the process then you will need to get a bigger carb for each inlet port of this engine. But this mostly because the engine maker started with almost too small of a carbonator to start with although this rare but it does happen. Now if you first started out and just quits as you start to rev your engine or it will only ideal means you will need to start with two times the jet area First thing is to buy new jets for your engine before starting the expansion chamber build(s) then use these to get the right sized twist drill bits as a set of them and get some very sticky tape for adding a finger useable surface for your fingers. Now once you have done the whole process and have gotten the system to run max out you will be very glad you did it. Provide it just scream so much that you can't get used to it then you detune the system by changing the reflector-cone t a smaller angle which also makes a wider powerband at the same time if used a 22.5-degree angle then start by going to 15-degree angle you can go right on down to 3.75 degrees as a minimum angle for the reflector-cone.
Great short block to build your own version of a Frankenstein or a iron sleved jug but that bt top ends are cheap shithole country aluminium. Reminds me of how us old timers that built Harleys in the 70s looked at the metal on the Sears and Kmart dirt bikes even some Italian bikes. Now thoes old bikes make this Chinese mettle look llike Gold. I'm just building a revenge bike myself to harass the law and show em how much I care they took my motorcycle licence away because some retarded cunt ran me over and took my leg. Adapted 18 " dirt bike rims to some old motocross bicycle hubs my son used for professional racing and jumping in the 80s.Thes 20" rims have hubs w bearings bigger then mopeds and 5/8" studs. They don't make frames drilled big enough to fit em these days. Hand drill did the job though. I paid over 350 in 1985 for my 12yr old sons Bicycle. Later that season he got a local sponster then went nationwide. Peddling dirt bikes Lol. Erupean tour. Damn kids are in their 40s today and still riding their skateboards and 20" motocross bikes to work as Game Developers. lol. Knees blown out and bones that never healed right. Kids were tough back then. Unlike Soybois today he he. But not as tough as us old 1% outlaw bikers that raised em.. FTW. (Forever Two Wheels)
Just to let you know; the only pistons worthy have 3 rings. #1 solid ring for compression #2 oil ring keeping bore nice and moist & #3 another compression ring. Keep the rubber side down!
It seem to me you play with the stuff but don't really know that much on engine design. I might be wrong but if you don't know about the 3 rings and the effect thereof, and jugging the engine by its looks, your comment is questionable... Sorry dude no offence.
@@diychad7268 in very short , it handicap the engine completely. Reduces efficiency, worse feul consumption, more friction. No real benefits , except maybe towards compression benefit...
@@diychad7268 nope . Sealing of the rings is only one part. Friction of the ( rings thickness,amount of rings and the pressure between rings and the sleeve's surface) causes more negatives than positives unless compression is raised significantly to justify the extra pressure of the rings. Is the motor used for drags?(rebuild after the race) or for everyday fun ?
Friend of mine was getting 5~6bhp from 32cc weed wacker motors 15 or so years ago.Could have gotten more but RC boats need some low speed torque. He's into RC helicopters now (was 'Toxic Marine' ) It's much much easier to port a larger diameter cylinder but reliability will suffer. Could and probably should have head machined off block then get a two piece watercooled head (yopu can change combustion chambers) Head is actually quite easy to make but very time consuming for initial design and not cheap until you can CNC 10,000 of them
From what I understand, Zeda motorsports is a tuning/styling manufacturer based in thé USA, JL Zeda Is the chinese produscer of thé engines only Stock.
Yes, jlzeda is the manufacturer in china. Zeda motorsports began as a distributor for jlzeda. Long story that isn't important. Keep your eyes on jlzeda, huge things coming soon. :)
@@JamesPiccone not true my $700 motor from rob is amazing faster then my 212cc I've got the torque monster from zedamotorsports.com love it worth every penny i spent & minute that I had to wait since I waited a month for it I would order it again
@@mbrrideitlikeyoustoleit8436 ruclips.net/video/P3_Nqc2iN9Q/видео.html keep telling yourself that bro 👍. You must be new to this but everybody in the motorized bicycle community knows zeda Mafia AKA zeda Motorsports are con artists hacks. A simple search on the forums would tell you that.
If you wanna make it faster straight pipe it. You have to cut off the exhaust and just leave the first part of the exhaust that is connected to the head of the motor. Trust me I did it and it gives it way more power and it will not break I swear I had it like that for like 3 months.
I've seen a lot of variations in the torque values on the head bolts I.e. between 7.1 and 11.5 that's a significant difference. Of the 4 bolts no 2 were the same.
Use a laser temperature gun to test the head heat at idle and wide open throttle. And test other engines to see where they're at. Those side way fins may not be so good. I'm thinking about a 2-stroke engine for my beach cruiser bike as long as I don't have a lot of problems with it. And I can still relatively pedal the bike easy with the engine off.
better buy about 3 cylinders along with your new engine cause the chrome plating will only last 500/1000 miles just like they did on the original CG cylinders. this new BT100 is just a sales gimmick to lure in the idiots. 3 compression rings will cause extra friction/heat what a joke.
Javy Mcdeez zeda mafia has a forged head full steel cylinder wall engine its a beast full hp up too 8 hp its a beast of a engine up too 12 hp with upgraded everything will run forever aslong as u dont over heat it
More friction in theory, but look at the ports. More rings but less cylinder wall surface. I'd say it's exactly how it should be. Plus, more rings make for a better-balanced piston. Keep it well lubed, use good fuel, oil, and it should last at least 3 months like the other Chinese-style 2-cycle bicycle engine kits on the market before things start crapping out. No wonder they say these things are for racing. If you're looking for long term reliability, upgrade to a Honda engine and Kevlar belt transmission. I tend to be cheap and lazy about it and get a friction drive kit with a Honda engine, and then I put a Kevlar tire on the wheel I drive. Last time I had 1 it was with a 25cc 4-cycle engine, .930" roller, 26" tire and while it didn't get me past 25MPH at top speed or over 16MPH up any hill, I've never had a similar sized 2-cycle engine that beat it right out of the box, or any size 2-cycle kit beat it over the long haul. Too bad some asshole ripped me off, and I'm not getting that bike/engine kit back. I wouldn't want it anyway. He probably trashed that, too. Anyway, if you want fast acceleration and higher potential top speed for short runs, go 2-cycle and chain drive with manual clutch. If you want slow acceleration but relatively high and consistent top speed for long trips, go with mini-4 stroke and either belt drive or friction drive with auto clutch. For comparison, I figure the 25cc friction drive kit I used could match pace with a 48cc Chinese-style 2-cycle engine kit I used with a 44T rear sprocket several years ago, if only for about 10 miles before something would need to be tightened or adjusted on the 2-cycle kit. The 1.5L tank on the 2 cycle kit or the 16oz tank on the mini 4-cycle kit both got about the same range when hooked up to their corresponding engine kits. If I read good things about the BT-100, I might get 1 if any are still in stock in a few years. 1st I'm upgrading to a 35cc mini 4-cycle engine kit with the same roller size next year, then getting a better bicycle and tires for it the year after that if I still can. I don't expect to win any races against the 100cc 2 stroke engine-powered bikes any more than a 25cc engine powered bike could beat a 66cc engine powered bike in a fair race, but when I can make 100 mile trips in 1 day, once a week, with no signs of quitting for nearly half a year, I know I have some reliable transportation. I can still race the rich-ass neon spandex crew with their short shorts, fancy pants road racing bikes, Oakley sunglasses and Go-Pros if I want to lol... To each his/her own.
Technology seems very close to cheaper chain saws I serviced while working for Sears. Those bores look to be unplated bare aluminum castings, typical also of some inexpensive weed whacker engines. Durability is the question with that - 2 stroke motorcycles I worked on during my career all had iron or steel liners or were plated with Nikasil or chromium. Three rings is highly unusual, last I saw was on high quality German two strokes of the late '50s and early '60s.
I'm wondering why the head's top portion is oriented sideways? Is there some advantage to that? And why a one piece head in the first place? So many questions...

You should have measured the stroke so you could verify the displacement.

@@oldtrip1765 length of the rod has no influence on the stroke.
The piston diameter and rod length (or stroke length) combine to give u displacement data
@Nimbus Nimbus T he stroke is fixed by the " throw" of the crank. You can double the length of the rod and it has zero affect on the stroke.
It'll flat- line a little after mid-range power hits... porting should stretch it's top speed a little. It's nice but only for good bottom end power. Though I could be wrong because it does seem to have a shorter rod.

Awesome! Thanks so much. Stay safe out there!
Try taking it apart and putting it back together to see the components inside and then make a test run video but off the back I wouldn't spend no 280 for that like you said I would expect a starter
I could do without the starter if it had a 2 ring piston a cast iron liner and a removable head. this variation they are casting now is a total engineering joke.
Good video mate thanks from england
AF80 is on the connecting rod, not the crank...
Lol I know
Yeah. I noticed he messed up
it's really cool to watch someone open a box ... get with the program, you think?
Some people enjoy it! Thanks for watching 👍
Would like to see what you think, and see it on a bike running.
Didn’t know the bt100 has PK80 rod wonder if the crank is the same balanced crank
i used to tear apart engines just to see the inside when i was 10
No shit, me too. usually locked up or worn out ones.
Same here except squirrels
I'm 12 and I tried doing it with my dad's new Tesla.... He's told me I'm getting no inheritance!.
I would have subscribed it I didn't have to spend my time watching you open boxes. Learn to edit!!!
I didnt have that kind of priviledge. Instead I started learning about engines 2 to 3 weeks ago reading and watching videos and looking at diagrams on my phone
xD
You can buy them from a zeda distributor in Canada called mobettabikes
As long as the cooling is kept in check for the MODERATE (not full out performance driver) the thing should do alright. Larger piston, more CCs and further out of bounds there legally in most places still though. I'm a four stroke guy myself. My bike was built for utility over performance.
the cylinder is from chain saw?looks exactly like!
I think thats what they styled it off of. Franks are becoming popular and they wanted in!
The box is worth more than the motor
Oh you will also need to make the main jet larger by total area the jet you are using times the pressure boost as atmospheres this not easy to do but you can read about the processes for doing this if you think that what I had written was long then you will need to take time to study jetting and engine for the first time. Tip: The engine will surge like it is missing that is the symptoms of too low of fuel in the cylinder which means that you will and must do fuel enrichment processes. It may blog-out just before you start to scream again you need to do fuel enrichment processes. First, check the sparkplug(s) this should be almost brownish in color (colour) but with these symptoms, the sparkplug(s) will be starch white this is the time to study fuel enrichment processes. It will be really worth it time. If the engine just starts to go then lags back you will enrich the fuel mix SECOND TIP: Get the jet flow area and multiply it by 1.5 this will equal the new first step now find the new diameter go get a drill of that diameter and hand drill the hole do not use a power drill ever while doing these drilling process use tape that sticks very well wrap it around the back end of the bit use your own fingers to power the drill bit through the jet for however many cylinders that there are then install and test. you will be doing more drilling on these jets very shortly again just keep making them larger step by step get more drills sizes. SEE the fact that you have done the other work correctly is why the carburetor just can not supply a rich enough fuel mixture the ait is passing through the carb so fast that it just can not supply the fuel for it. A word to be noticed is if you can not get it to enrichen the mixture enough after drilling out the jets four or five times through the process then you will need to get a bigger carb for each inlet port of this engine. But this mostly because the engine maker started with almost too small of a carbonator to start with although this rare but it does happen. Now if you first started out and just quits as you start to rev your engine or it will only ideal means you will need to start with two times the jet area First thing is to buy new jets for your engine before starting the expansion chamber build(s) then use these to get the right sized twist drill bits as a set of them and get some very sticky tape for adding a finger useable surface for your fingers. Now once you have done the whole process and have gotten the system to run max out you will be very glad you did it. Provide it just scream so much that you can't get used to it then you detune the system by changing the reflector-cone t a smaller angle which also makes a wider powerband at the same time if used a 22.5-degree angle then start by going to 15-degree angle you can go right on down to 3.75 degrees as a minimum angle for the reflector-cone.
from the picture on utube this new engine looks like an old MZ/CZ engine from back in the day!!!!
Chinese copycats.
Total Knowledge Fest
yay a new BT Series engine, hopefully they make an electric start version
Great short block to build your own version of a Frankenstein or a iron sleved jug but that bt top ends are cheap shithole country aluminium. Reminds me of how us old timers that built Harleys in the 70s looked at the metal on the Sears and Kmart dirt bikes even some Italian bikes. Now thoes old bikes make this Chinese mettle look llike Gold. I'm just building a revenge bike myself to harass the law and show em how much I care they took my motorcycle licence away because some retarded cunt ran me over and took my leg. Adapted 18 " dirt bike rims to some old motocross bicycle hubs my son used for professional racing and jumping in the 80s.Thes 20" rims have hubs w bearings bigger then mopeds and 5/8" studs. They don't make frames drilled big enough to fit em these days. Hand drill did the job though. I paid over 350 in 1985 for my 12yr old sons Bicycle. Later that season he got a local sponster then went nationwide. Peddling dirt bikes Lol. Erupean tour. Damn kids are in their 40s today and still riding their skateboards and 20" motocross bikes to work as Game Developers. lol. Knees blown out and bones that never healed right. Kids were tough back then. Unlike Soybois today he he. But not as tough as us old 1% outlaw bikers that raised em.. FTW. (Forever Two Wheels)
its298$
Just to let you know; the only pistons worthy have 3 rings. #1 solid ring for compression #2 oil ring keeping bore nice and moist & #3 another compression ring. Keep the rubber side down!
How much is that cool package set you back at
the cylinder is really the only difference but most likely they changed the stud spacing to keep it kosher
bout time they made a real 80cc ( technically it's a 79cc to be exact) but never the less can't wait to own one
its 74.6cc to be exact
Does the motor put out six or 12 V
Six, they make a little 12v coil but it's a poo
I hope this engine last long and goes the distance But it is an awesome looking engine Oh Yeah !!! And by the way great video Always nice ones !!! 👍👍👍
It seem to me you play with the stuff but don't really know that much on engine design. I might be wrong but if you don't know about the 3 rings and the effect thereof, and jugging the engine by its looks, your comment is questionable... Sorry dude no offence.
Completely agree.
fill us in on the 3 ring and effect :)
@@diychad7268 in very short , it handicap the engine completely. Reduces efficiency, worse feul consumption, more friction. No real benefits , except maybe towards compression benefit...
@John Doe soooooo a loss of vacuum pressure then in other words??
@@diychad7268 nope . Sealing of the rings is only one part. Friction of the ( rings thickness,amount of rings and the pressure between rings and the sleeve's surface) causes more negatives than positives unless compression is raised significantly to justify the extra pressure of the rings. Is the motor used for drags?(rebuild after the race) or for everyday fun ?
Definitely worth $2.80 I’ll have to get one on a bike to find out if it actually is $2.80 is about right for a Korean motor
How long is the stroke
Can you measure the distance between the bolt holes in the case (the ones that keep the cylinder/head combo on)
Looks to be right at 52mm. It does not rly fit any chainsaw head.
Only thing I like is the 50mm piston...
Friend of mine was getting 5~6bhp from 32cc weed wacker motors 15 or so years ago.Could have gotten more but RC boats need some low speed torque. He's into RC helicopters now (was 'Toxic Marine' ) It's much much easier to port a larger diameter cylinder but reliability will suffer. Could and probably should have head machined off block then get a two piece watercooled head (yopu can change combustion chambers) Head is actually quite easy to make but very time consuming for initial design and not cheap until you can CNC 10,000 of them
I’d hook that to my blender and make some frozen margaritas
Looks like I’m putting my engine on facing the wrong way. What’s up with the cooling fins?
Also a question JLZeda or Zeda Motorsports, which one is better or is it the same.
From what I understand, Zeda motorsports is a tuning/styling manufacturer based in thé USA, JL Zeda Is the chinese produscer of thé engines only Stock.
Yes, jlzeda is the manufacturer in china. Zeda motorsports began as a distributor for jlzeda. Long story that isn't important. Keep your eyes on jlzeda, huge things coming soon. :)
JL zeda is the legit one zeda Motorsports is a hack that sells other people's shit and are straight up con men.
@@JamesPiccone not true my $700 motor from rob is amazing faster then my 212cc I've got the torque monster from zedamotorsports.com love it worth every penny i spent & minute that I had to wait since I waited a month for it I would order it again
@@mbrrideitlikeyoustoleit8436 ruclips.net/video/P3_Nqc2iN9Q/видео.html keep telling yourself that bro 👍. You must be new to this but everybody in the motorized bicycle community knows zeda Mafia AKA zeda Motorsports are con artists hacks. A simple search on the forums would tell you that.
If you wanna make it faster straight pipe it. You have to cut off the exhaust and just leave the first part of the exhaust that is connected to the head of the motor. Trust me I did it and it gives it way more power and it will not break I swear I had it like that for like 3 months.
Till your next door neighbor got fed up with the noise and dumped sugar in you gas tank😃
They need to change the direction of those fins
they? you mean job security joooos?
@@javymcdeez3958 no. I mean the people who designed it for motorised bikes
Having spark issues on a Thundershirt motor kit replace the CDI coil have not replace the stator any comments or thoughts would be appreciated
brent_sr@yahoo.com
Yes it looks good, looking forward to buying one.
Hahahahaha
I've seen a lot of variations in the torque values on the head bolts I.e. between 7.1 and 11.5 that's a significant difference. Of the 4 bolts no 2 were the same.
Heh they don’t know what a torque wrench is in China ,India, SE Asia only the Japanese & Koreans use them
6:10 to fast forward the unboxing Hellooo 👍
Lol
Looking forward to seeing it on a bike
6 minutes to open the boxes...not looking good
Use a laser temperature gun to test the head heat at idle and wide open throttle. And test other engines to see where they're at. Those side way fins may not be so good. I'm thinking about a 2-stroke engine for my beach cruiser bike as long as I don't have a lot of problems with it. And I can still relatively pedal the bike easy with the engine off.
better buy about 3 cylinders along with your new engine cause the chrome plating will only last 500/1000 miles just like they did on the original CG cylinders. this new BT100 is just a sales gimmick to lure in the idiots. 3 compression rings will cause extra friction/heat what a joke.
Just what I was thinking, remove the bottom ring..
Javy Mcdeez zeda mafia has a forged head full steel cylinder wall engine its a beast full hp up too 8 hp its a beast of a engine up too 12 hp with upgraded everything will run forever aslong as u dont over heat it
More friction in theory, but look at the ports. More rings but less cylinder wall surface. I'd say it's exactly how it should be. Plus, more rings make for a better-balanced piston. Keep it well lubed, use good fuel, oil, and it should last at least 3 months like the other Chinese-style 2-cycle bicycle engine kits on the market before things start crapping out. No wonder they say these things are for racing. If you're looking for long term reliability, upgrade to a Honda engine and Kevlar belt transmission. I tend to be cheap and lazy about it and get a friction drive kit with a Honda engine, and then I put a Kevlar tire on the wheel I drive. Last time I had 1 it was with a 25cc 4-cycle engine, .930" roller, 26" tire and while it didn't get me past 25MPH at top speed or over 16MPH up any hill, I've never had a similar sized 2-cycle engine that beat it right out of the box, or any size 2-cycle kit beat it over the long haul. Too bad some asshole ripped me off, and I'm not getting that bike/engine kit back. I wouldn't want it anyway. He probably trashed that, too. Anyway, if you want fast acceleration and higher potential top speed for short runs, go 2-cycle and chain drive with manual clutch. If you want slow acceleration but relatively high and consistent top speed for long trips, go with mini-4 stroke and either belt drive or friction drive with auto clutch. For comparison, I figure the 25cc friction drive kit I used could match pace with a 48cc Chinese-style 2-cycle engine kit I used with a 44T rear sprocket several years ago, if only for about 10 miles before something would need to be tightened or adjusted on the 2-cycle kit. The 1.5L tank on the 2 cycle kit or the 16oz tank on the mini 4-cycle kit both got about the same range when hooked up to their corresponding engine kits. If I read good things about the BT-100, I might get 1 if any are still in stock in a few years. 1st I'm upgrading to a 35cc mini 4-cycle engine kit with the same roller size next year, then getting a better bicycle and tires for it the year after that if I still can. I don't expect to win any races against the 100cc 2 stroke engine-powered bikes any more than a 25cc engine powered bike could beat a 66cc engine powered bike in a fair race, but when I can make 100 mile trips in 1 day, once a week, with no signs of quitting for nearly half a year, I know I have some reliable transportation. I can still race the rich-ass neon spandex crew with their short shorts, fancy pants road racing bikes, Oakley sunglasses and Go-Pros if I want to lol... To each his/her own.
Take two rings off
You only need one anyway
Technology seems very close to cheaper chain saws I serviced while working for Sears. Those bores look to be unplated bare aluminum castings, typical also of some inexpensive weed whacker engines. Durability is the question with that - 2 stroke motorcycles I worked on during my career all had iron or steel liners or were plated with Nikasil or chromium. Three rings is highly unusual, last I saw was on high quality German two strokes of the late '50s and early '60s.
Omg its a 100cc bike kit. Mind blown😒
Hi brother can you help me.How to install electronic starter in 80 cc 2 stoke bicycle engine.kindly please make a video on this.
I would think it would be more trouble than it's worth. I would try to find a good pull start instead.
They need to make a 250cc
cant even make a 80cc could never make a 250cc stay running longer than 100 miles
I love how the cooling fins on the head face the wrong direction
Right! Whoops
Really unboxing ?..tuned out
good job on the work benches like they were made yestarday.
Thank you! That actually means a lot to me. 😆
ha ha ha stop paying so much attention!
It’s 100cc if I remember
79, 100cc is just what they call it,
You want to make that little motor fun put a reed valve in it. Then port and polish it, there you go, two strokes are fun.
Won't mess w it at that price +..Az has awesome laws but yr round sunshine., My dog Has to wear a swamp cooler vest just to walk around the yard.
I'm wondering why the head's top portion is oriented sideways? Is there some advantage to that? And why a one piece head in the first place? So many questions...
50 mm piston. Shit. Just brought a Frankenstein engine and boy is it a skillet. Runs hot as hell and uses Race fuel only.
Ive found out the ms440 do not run as hot as the ts400.
Motored Life..... I wonder who told you how to build that
@@MotoredLife you choice of 2 cycle oil has alot to do in this venue.
@@MotoredLife Thanks for the advice Think Im ready for a rebuild. My Skills are up. Ebay has the right prices.
spending on upgrades is fun to a point ,just buy something you dont need to floor it all the time ,a 110cc 4 stroke is my fav
Use a chainsaw piston Stihl or Husqvarna
@Pops Fereal because its a better piston
@Pops Fereal do I have a 47 mm cylinder? Or a 48 millimeter?
