PLEASE DROP THE MUSIC !!!!! just about anytime I go on a site with loud music in the background I hit exit. I've started leaving comments such as this. You ruin your otherwise good info with the music. Cheers !
One problem with both designs is there are no vents to cool the internals. I have the smaller, stock one shown in the video, which got extremely hot even with fresh lubrication, almost as hot as the exhaust. Within under 100 miles of riding, the chain was so stretched that it slipped right off. After 3 crude attempts at fashioning a suitable chain tensioner for this narrow enclosure, I gave up and decided the best option was to simply cut off, reposition, and remount the drive sprocket end to the face-plate. Also required are some air holes in the front and back, which could have prevented the need for this fix for thousands of miles. Got what I paid for on this budget ebay engine kit...
Simple ASMR really? if the background audio is even close to the volume of the actual video... it's too loud. Not like this is really a unbiased top notch review worth watching anyway
I think the main selling point for me (besides the things you said), is that I can change my gearing to my needs. Power sprockets and speed sprockets are important.
I have some videos on CVT and fixed gear units tried and what failed. Those holes in the clutch bell are needed for cooling, heat is the enemy of those friction clutches.. You would be better to have a vented casing or caged top cover, there is no gain to having it enclosed it only traps heat. Chains do not need grease on the outside and it just flies off anyway, they need lube on the inside on the pivot pins. Put chains in a hot chain lube bath that sets solid inside the pins. It will be faster and cleaner in production hanging a bunch of chains and lowering them in a lube bath then hanging to drain and cool than greasing them like that and will provide better lube over life that wont run out or fly off.
Find and old 50-70cc Mini trail Auto transmission (usually 3 spd) and they made a honda in the early 80s that was a street bike and it had and Automatic Transmission (I believe it was a 4 or 5 spd
@@rustbeltgypsy3713 In 1972 I had a Honda mini trail 50 mini bike.Handlebars folded down pegs folded up to put it in dads trunk.Anyway 3 speed no clutch.
The problem is the clutch it wears out fast due to the force placed on it and the heat it gets really hot . The shoes on mine wore out on a couple of rides and left me stranded. The clutch on these are not realible. Iam using the ezqmatic now much better clutch but heavier transmission . But last longer before replacing clutch.
Wouldn't it be a lot better to seal the housing and put some 75w140 gear oil in it? Just enough for the big sprocket to dip? Also I would think that doubling the gear ratio is a bit overkill unless you also sell different sizes of rear sprockets for the bicycle.
Your transmission is so smooth and take off power is fantastic. It will pull up a hill or into the wind with no problem. You sacrifice a little top end but riding for pleasure means it’s not an issue. Great job everyone.
Would be a good video if you actually ever had these products in stock.. I swear I don't know how you keep open, any part I have ever been in need of you are always out of stock on. It never fails
pds tech: I wonder if I might put it another way for you. Once all that grease has flung off onto the casing it will likely stay there, serving no further benefit. However chains and sprockets love lubrication for long life. Perhaps if they could seal that housing and either run oil in there or a thick honey grease which can always get back onto where it is needed it would be much better.
Will I mean most people will also slap this right on the engine from the box. At least they would not run it bone dry. Plus I like to to open every gallon or two and add some mobile 1 synthetic grease with a cotton swab on each link. Just my two cents.

While I enjoyed you video about transmissions, I’m looking at building 4 different but equal sized bikes. Each bike will have a different engine, while 2 engine are easily available, it is the others that I need help with locating or having built, a 4 stroke diesel with the displacement of 49cc, and a 49cc 2 stroke diesel. These will not only be used as transportation, but also as test engines for economy, and durability. Any help with locating the 2 Diesel engine and configuring a transmission set up will be greatly appreciated thank you for your help. Ps. I’m thinking of using a “CVT” transmission setup with a belt final drive.
Ok all very good points and big difference in quality. But I did not hear anything about price difference? Plus we are talking about 49cc four stroke engines, that if your lucky make what 1-2 hp and 2-5 lbs ft tq? Yes the Double chain system will run longer, probably longer than the engine! To make a determination I’d have to compare prices. What would really be something is for someone to design and build a torque converter the same size! That would be amazing!

I always wondered why the bikeberry four-stroke engine kit always got really bad reviews, it looks really good compared to some of the other kits. Well I bought it and now I know why. Here's the lowdown, engine is really nice, wide crank arms are really nice. The mounting plate is even pretty nice, I had to drill the holes out a little bit to make them bigger but it is very solid. So why does this kit get such bad reviews. Worst transmission by far out of all the 49cc Transmissions. The transmission they are trash talkin is probably the best one. It's a $50 transmission when it starts to fail you just buy a new one. The transmission that comes with the bikeberry kit is absolute garbage. Not smooth at all, and doesn't work very well with a 415 chain ether, I don't know what chain it does work well with but definitely not a 415.
@@kaedon5241 I don't think they sell the single chain ones by them shelves any more, gas bikes used to sell them, they're not the best though. Spend the extra money on the Knight G8 transmission from king motor bikes or Gass bikes. A little pricey but the one I have has thousands of miles on it, I had to change a $10 belt on it once, only because I whacked it pretty good with the pedal. That and they don't blow through clutches like the other single change transmission does. You also have to go with a smaller Sprocket in the rear, they're geared quite a bit lower than the single chain transmission.
@Marc S could you link it? I can't find it but I ended up just buying another single chain transmission but when that one goes out I'll probably just get that g8
@@kaedon5241 I'm looking around, looks like things have changed in the last year 2 or so, gas bike looks all sold out, I saw some on eBay that look pretty good, not called G8 but they look the same $120 ish.

Hey Alan !! Informative video about the 4 stroke transmission !! But I have a simple question for you though ?? Will the bike berry transmission work on a huasheng 49cc 4 stroke ?
It will but mine wouldn't work with a 415 chain so completely useless I don't know what chain it does work with stay away from the Blackberry Transmission in my experiences it's the worst one
I like this transmission for the 4 stroke engine and am wondering 2 things the first is will this work for a 125-150cc engine and 2 will it work with a jack shaft so that you can run it off of the original gears of the mountain bike please let me know?
You are completely right. We did not properly plan for this video and should have compared more transmissions and have put them through actual tests. We are constantly trying to improve the quality of our videos to make it as informative and entertaining as possible.
Hey Alan ! Quick question for ya ! I have a 49cc r stroke huashengtaishan and the trasmission failed riding it to work !! Does the bike berry trasmission work on the huasheng motor ? I want to get the best one tjat i can buy ? And thanks man for your time !!
WHERE CAN I GET A NEW TRANSMITION MINE BROKE WHEN I INSTALLED A 36 TOOTH REAR SPROKET SO I BOUGHT ANOTHER ENGINE. i BOUGHT A ZETA 100 DIO REED VALVE ENGINE AND ITS JUNK THE 4 STROKE IS MUCH MOREW RELIABLE BUT I WANT TO GO FAST CRUZE AT 40 WOULD BE GREAT.
I’d take the cheap one, you don’t need double row chain for such a low hp motor and the hp you would lose with all the friction and grease, just a bit of chain lube on the cheapo will out last your knock of engine or last your phase you are going through
lol no but i wish, you could however put a gokart clutch on the keyed shaft of those harbor freight engines and they would hook right to the chain and sprocket on the standard motorized bike kit
Chayton Ruijsenaars deathrow kit( the harbor freight 212 )use gokart clutch and tav2 options..as for the monster 80(the harbor freight 79cc )you got many vendors such as ezm q-matic,gas bike style transmission,as well as akg stuff which i cant remember
Chayton Ruijsenaars but never the less ill build me a 212 with a tav2 setup motorize bike next maybe from scratch because money is an issue ..so i rather collect parts little by little.
hearing all these problems on the internet geez I'm better off just making it old-fashioned I like it because it's covered up but yes I can make a cover for my myself let me know if you guys come up with solutions to your problems
Not in my experence. I had a 4G that broke on me twice within the first month & just got tired of fixing it. I don't think its that much more reliable than any other cheap Chinese made 4 stroke transmission. The clutch bell & the nuts & bolts are crap. The best transmission you can get for those 4 stroke engines is the EZM Qmatic but it costs twice what the 4G costs & requires an adapter to make it work on tapered shaft engines. I converted to a 2 stroke because they are far more simpler & cheaper & can outlast most 4 stroke kits if installed right with good quality hardware. Had to get used to mixing oil with gas though but it became almost second nature to me now. If you ever do go with a 2 stroke get the Zeda80 from Bicycle Engines. com. Its the best 2 stroke out there & you can choose sprocket sizes before you buy.
Do you have a 7G T-Belt Drive transmission gear box / 5/8 shaft, I purchased a 4 stroke 49cc motorized bike with belt drive transmission gear box ,and I'm having problems with the sprocket that fits the back wheel sprocket, what can I do to resolve this problem, the sprocket on the transmission gear box seems to be very loose maybe it's the bushings, I don't know
hey bike berry I have a schwinn JAGUAR beach cruiser it has 7 gears to change into the rear wheel the pedals only have one gear I want a 4 Stroke engine but I don't know what kind of kit I need with the 7 gears and also I try to look up 4 or 2 stroke instalation videos on bikes with gears ( 10 speed, 7 speed, mountain bikes or a bike like mine's ) but no luck do you guys know of any video or you think you guys can make a video about this it would be a big help to new customers THANKS SOON TO BE A FIRST TIME CUSTOMER AND RIDER CAN'T WAIT 😆 👍
My bike also has the 7 gears,when you get the motor it comes with 1 gear that goes on the opposite side of the tire. You do not use the 7 gears for the motor only when you want to pedal the bike.Trust me you will be peddling! mine beaks down all the time and I have less than 300 miles on it!
Omar Coronado you dont need to worry about that...here the thing you can use an independ drive system like its intended for or go exspensive and get a shift kit..
Is there any way to adjust the drive sprocket on the transmission by moving the drive sprocket shaft in or out a little bit more if so please explain thank you good product
if you break a gearbox chain your fkt, you can't by the chains I've broken the chain twice the chains are to week for these engins, they should use a 410 415 chain only or big ads cogs both these gearboxes need throwing in the bin also I broke the clutch bell she hits 38mph I only go 25 and still broke it with only 1 tank of fule. chains stretched as well, getting wide peddles cranks is not possible as well, you would not need a large crank rod that is over 20cm long if the peddles in the kits had a wider spacing, my kit did not come with a crank rod, and the wide peddle arms need to be wider to except the standard crank rods, in Australia u can't get these rods nore the chains nor the 1 pice crank nor anything, Alibaba only sells engine kits not the parts nor crank arms and eBay don't sell them nor does not does crap ass Amazon, sell the chains or peddles kits bike berry is the only one of about 4 USA sellers but they only sell to USA.
It is because of the risk of chain and cog breakage that we began to carry the heavier transmission. It evenly displaces tension across both cogs and chains. We do sell outside of the US, the only issue being the cost and time for shipping.
i would like to have more information on you'r transmissions if you have anymore.and i would to find out how i might buy one of you'r engine trans. combo's in canada.i would like a high speed combo for cross country travel so engine size would not matter with the law because it would all be off-road riding.and i would like to know what is the largest cc engines that you sell.thank you for you'r time.
I have had to change the chain shaft sprocket 2 times because they just snap in half,also the clutch hub snapped at the weld.So this is 4 times I broke down miles from home!I have less than 300 miles on the thing.Not fun for me to walk the bike home,I'm a heart patient,1 total knee replacement 6 months ago,the other is being replaced this winter.I have a steel rod in 1 leg, and I'm a diabetic pushing 60, and I ride like a 60 year old man-slow.I would not recommend getting one of these bikes unless your healthy enough to push it just about every time you use it!!!!
Not necessarily BikeBerrys products. In general the clutch systems for these bikes suck.Mines all china made and now since I commented and replaced those parts again the motor is running like shit.I'm pretty good with mechanical things(motors and such)so my advice would be not to buy the cheaper versions of these kits from anyone. BikeBerrys service is great.You get what you pay for is all I can say.
Just a heads up for you.I replaced the clutch bell rotor in July and it's only Aug. 30th and it has broken too.Iv'e driven it less than 60 miles this time.So far now this is 3 clutch bell rotors and 3 chain sprocket gears at about $120,plus waiting for shipping and doing the work on it too.I'm 57 years old 190 lbs and I ride like an old man would.The motor was running shitty as I said before and I figured this out too.The inside if the gas tank rusts terrably and ends up clogging the gas filters(one is in the shut off valve on the tank itself) so you have to clean the carb out also and change the gaskets..I do keep fixing these things because it is a blast to ride it when it's running. Mine is the flying horse 49cc 4 stroke.
The problem, is the cheap kits are designed for motor assisted pedaling... it appears the bikeberry transmission is designed more for motor only riding. The problems you had with your motor, clogging filters and carbies, can happen with any make or brand.. Whether it's a Honda or Chinese replica.. I suggest checking your fuel source too for contamination.
how is this a transmission? its just a damn centrifugal clutch with a chain in a box. just get the cluch and run straight to wheel sprocket for more power and less fail.
RattleSnake6302 i can answer that for you ..technically no..but it have a clutch flyweight that expands and the clutch bell catches it and put power to your rear wheel.
99$ is a quite high price! I am from Bulgaria and this is like 170 lv. I can build even better quality gearbox for half of that price and sell them online.
Stoyan Zashev; the 5G dual chain is just a modified CVT pocket bike transmission & those single chain CVT pocket bike transmissions cost about $30. The single chain transmission shown in the video is a pocket bike CVT transmission. I plan on just modifying that transmission with better quality components from Staton Inc. Would still be cheaper & hopefully better than the 5G.
Then do it and shut up about it. We are not from Bulgaria and neither is the shit this punk is selling. So make the gearbox and sell them for your Bulgarian bike builds.
Go to the bikeberry.com directly to ask this question, you will get a faster response, they may not see this question for a very long time maybe never.
Just got mine from bike berry and the clutch bell is too shallow to work properly... Not a compatible product. If I do decide to return I have to now pay return shipping AND a 15% restocking fee taking a huge gouge out of my pocket. That sucks because I feel the product is misrepresented as being compatible with all Honda replica engines.
If you are using one of these engines you should not be having any troubles. Please call us and email some pictures to support@bikeberry.com ... (800)317-0479
It is a generic brand that is extremely popular and can be easily purchased on ebay. Many of these type of transmissions use this exact same transmission and simply re brand the product.

do a test on this transmission so we can see what its really like
Gear box not sold individually?
Could you not just copy the sprocket teeth numbers to the main drives and get same results and not have the xtra weight?
This is old. All the 4 stroke kits now have double chain drive. But you should always lube them first before start up.
Mine doesn’t have double chain drive🙁 chain loosened up and is unusable.
@@rideallegretto1933 hit up Ebay for a dual chain drive one for under 40 bucks! 👍🏾
@@heavystarch100 yeah I tried looking before but couldn’t find one for under 60.
How much for the product?
I have a 100cc honda clone. Will this gearbox work? If not, what would you suggest?
Hey Alan ! Quick question for ya ! I have a 49cc r stroke huashengtaishan and the trasmission failed riding it to work !! Does the bike berry trasmission work on the huasheng motor ? I want to get the best one tjat i can buy ? And thanks man for your time !!
Kelly Brooks it will work if it’s an 142f engine
Hi i just wanna ask if this kind of transmission is also fit to honda gx35 4stroke or other 4stroke grass cutter engine?
thank you..
Does it works with the normal 49cc gearbox give me a quick answers please
WHERE CAN I GET A NEW TRANSMITION MINE BROKE WHEN I INSTALLED A 36 TOOTH REAR SPROKET SO I BOUGHT ANOTHER ENGINE. i BOUGHT A ZETA 100 DIO REED VALVE ENGINE AND ITS JUNK THE 4 STROKE IS MUCH MOREW RELIABLE BUT I WANT TO GO FAST CRUZE AT 40 WOULD BE GREAT.
I need one with paddle shifters
I’d take the cheap one, you don’t need double row chain for such a low hp motor and the hp you would lose with all the friction and grease, just a bit of chain lube on the cheapo will out last your knock of engine or last your phase you are going through
I need one
How can i contact you to purchase 7g tbelt transmission for four stroke moter
will it work for a predator 4 stroke 97cc or 212cc?
+Ronny Khmai no
+Ronny Khmai it only work on pocket bike and weed wacker engines
lol no but i wish, you could however put a gokart clutch on the keyed shaft of those harbor freight engines and they would hook right to the chain and sprocket on the standard motorized bike kit
Chayton Ruijsenaars deathrow kit( the harbor freight 212 )use gokart clutch and tav2 options..as for the monster 80(the harbor freight 79cc )you got many vendors such as ezm q-matic,gas bike style transmission,as well as akg stuff which i cant remember
Chayton Ruijsenaars but never the less ill build me a 212 with a tav2 setup motorize bike next maybe from scratch because money is an issue ..so i rather collect parts little by little.
Why 4 stroke needs to be level phantom bikes got their motors tilt forward
Will a 49cc 2 stroke Transmission fit a 4 stroke 49cc Engine
No
Will this handle a 6.5 hp 212cc 4 stroke?
hearing all these problems on the internet geez I'm better off just making it old-fashioned I like it because it's covered up but yes I can make a cover for my myself let me know if you guys come up with solutions to your problems
yup
what is the name or model that has free wheel sproket inside... thank you
arent two gears and two chains more entropic
Bicycle Engines .Com sells a way better transmission that wont lock up on you. It belt driven 4g. Kits are better too. Dont trust these people.
Not in my experence. I had a 4G that broke on me twice within the first month & just got tired of fixing it. I don't think its that much more reliable than any other cheap Chinese made 4 stroke transmission. The clutch bell & the nuts & bolts are crap. The best transmission you can get for those 4 stroke engines is the EZM Qmatic but it costs twice what the 4G costs & requires an adapter to make it work on tapered shaft engines.
I converted to a 2 stroke because they are far more simpler & cheaper & can outlast most 4 stroke kits if installed right with good quality hardware. Had to get used to mixing oil with gas though but it became almost second nature to me now. If you ever do go with a 2 stroke get the Zeda80 from Bicycle Engines. com. Its the best 2 stroke out there & you can choose sprocket sizes before you buy.
How we buy it
Can you change the gear ratio on the transmission?
I bought this for my 79cc predator and I can't seem to get the bolt out-of the bell
A Comet-style go-kart torque converter is better than both.
Do you have a 7G T-Belt Drive transmission gear box / 5/8 shaft, I purchased a 4 stroke 49cc motorized bike with belt drive transmission gear box ,and I'm having problems with the sprocket that fits the back wheel sprocket, what can I do to resolve this problem, the sprocket on the transmission gear box seems to be very loose maybe it's the bushings, I don't know
hey bike berry I have a schwinn JAGUAR beach cruiser it has 7 gears to change into the rear wheel the pedals only have one gear I want a 4 Stroke engine but I don't know what kind of kit I need with the 7 gears and also I try to look up 4 or 2 stroke instalation videos on bikes with gears ( 10 speed, 7 speed, mountain bikes or a bike like mine's ) but no luck do you guys know of any video or you think you guys can make a video about this it would be a big help to new customers THANKS SOON TO BE A FIRST TIME CUSTOMER AND RIDER CAN'T WAIT 😆 👍
My bike also has the 7 gears,when you get the motor it comes with 1 gear that goes on the opposite side of the tire. You do not use the 7 gears for the motor only when you want to pedal the bike.Trust me you will be peddling! mine beaks down all the time and I have less than 300 miles on it!
Omar Coronado you dont need to worry about that...here the thing you can use an independ drive system like its intended for or go exspensive and get a shift kit..
Is there any way to adjust the drive sprocket on the transmission by moving the drive sprocket shaft in or out a little bit more if so please explain thank you good product

How do you find top dead center on the bell housing ? Because i just bought one and i can find any marks ?
Send wrong parts and cheeper parts then they say you gonna get so it's like the promise you a chocolate chip cookie but you get raisins
if you break a gearbox chain your fkt, you can't by the chains I've broken the chain twice the chains are to week for these engins, they should use a 410 415 chain only or big ads cogs both these gearboxes need throwing in the bin also I broke the clutch bell she hits 38mph I only go 25 and still broke it with only 1 tank of fule. chains stretched as well, getting wide peddles cranks is not possible as well, you would not need a large crank rod that is over 20cm long if the peddles in the kits had a wider spacing, my kit did not come with a crank rod, and the wide peddle arms need to be wider to except the standard crank rods, in Australia u can't get these rods nore the chains nor the 1 pice crank nor anything, Alibaba only sells engine kits not the parts nor crank arms and eBay don't sell them nor does not does crap ass Amazon, sell the chains or peddles kits bike berry is the only one of about 4 USA sellers but they only sell to USA.
It is because of the risk of chain and cog breakage that we began to carry the heavier transmission. It evenly displaces tension across both cogs and chains. We do sell outside of the US, the only issue being the cost and time for shipping.
i would like to have more information on you'r transmissions if you have anymore.and i would to find out how i might buy one of you'r engine trans. combo's in canada.i would like a high speed combo for cross country travel so engine size would not matter with the law because it would all be off-road riding.and i would like to know what is the largest cc engines that you sell.thank you for you'r time.
Contact our team at 1-800-317-0479. We're happy to answer any questions you have on our products.
I need a link to the gearbox that would fit a gx25 or transmission please .
how to make order sir
I have had to change the chain shaft sprocket 2 times because they just snap in half,also the clutch hub snapped at the weld.So this is 4 times I broke down miles from home!I have less than 300 miles on the thing.Not fun for me to walk the bike home,I'm a heart patient,1 total knee replacement 6 months ago,the other is being replaced this winter.I have a steel rod in 1 leg, and I'm a diabetic pushing 60, and I ride like a 60 year old man-slow.I would not recommend getting one of these bikes unless your healthy enough to push it just about every time you use it!!!!
Are you talking about BikeBerry products?
Not necessarily BikeBerrys products. In general the clutch systems for these bikes suck.Mines all china made and now since I commented and replaced those parts again the motor is running like shit.I'm pretty good with mechanical things(motors and such)so my advice would be not to buy the cheaper versions of these kits from anyone. BikeBerrys service is great.You get what you pay for is all I can say.
Just a heads up for you.I replaced the clutch bell rotor in July and it's only Aug. 30th and it has broken too.Iv'e driven it less than 60 miles this time.So far now this is 3 clutch bell rotors and 3 chain sprocket gears at about $120,plus waiting for shipping and doing the work on it too.I'm 57 years old 190 lbs and I ride like an old man would.The motor was running shitty as I said before and I figured this out too.The inside if the gas tank rusts terrably and ends up clogging the gas filters(one is in the shut off valve on the tank itself) so you have to clean the carb out also and change the gaskets..I do keep fixing these things because it is a blast to ride it when it's running. Mine is the flying horse 49cc 4 stroke.
My suggestion would be to buy an actual Honda engine and CVT for it. There's a reason these kits are so cheap
The problem, is the cheap kits are designed for motor assisted pedaling... it appears the bikeberry transmission is designed more for motor only riding. The problems you had with your motor, clogging filters and carbies, can happen with any make or brand.. Whether it's a Honda or Chinese replica.. I suggest checking your fuel source too for contamination.
how is this a transmission? its just a damn centrifugal clutch with a chain in a box. just get the cluch and run straight to wheel sprocket for more power and less fail.
Anything that that transfers power to the wheel is called a transmission. You’ll actually loose torque and horsepower if you use the pedal sprockets.
do the 4 strokes have clutches?
RattleSnake6302 i can answer that for you ..technically no..but it have a clutch flyweight that expands and the clutch bell catches it and put power to your rear wheel.
Centrifugal clutch
You all guys have jackshaft for 2-stroke Motors... but you guys don't have jackshaft for 4-Stroke Motors.... Why ??????????
What would happen if you put it on a 2 stroke?
If you had a 2 stroke that would take it it should work. The 2 stroke bike kits wont bolt up to this
The Dark Vortex wont work..unless its a pocket bike 2 stroke lol
You would be pissed because it will not fit your shity two stroke.
99$ is a quite high price! I am from Bulgaria and this is like 170 lv. I can build even better quality gearbox for half of that price and sell them online.
Stoyan Zashev; the 5G dual chain is just a modified CVT pocket bike transmission & those single chain CVT pocket bike transmissions cost about $30. The single chain transmission shown in the video is a pocket bike CVT transmission. I plan on just modifying that transmission with better quality components from Staton Inc. Would still be cheaper & hopefully better than the 5G.
Thanks for the information.
Then do it and shut up about it. We are not from Bulgaria and neither is the shit this punk is selling. So make the gearbox and sell them for your Bulgarian bike builds.
Dude my drive sprocket keeps unthreading itself and flying off!
Sir is that transmission gear box fit to 4 stroke grass cutter engine? Thank you. Waiting for your response sir. :)
Go to the bikeberry.com directly to ask this question, you will get a faster response, they may not see this question for a very long time maybe never.
Just a invent jackshaft for a 4-stroke motor... Plz
Can't understand through the music. Thanks, anyway...
Just got mine from bike berry and the clutch bell is too shallow to work properly... Not a compatible product. If I do decide to return I have to now pay return shipping AND a 15% restocking fee taking a huge gouge out of my pocket. That sucks because I feel the product is misrepresented as being compatible with all Honda replica engines.
Were sorry to hear you are having issues with this product. What engine are you trying to use this on?
@@bikeberry the exact engine featured in this video
If you are using one of these engines you should not be having any troubles. Please call us and email some pictures to support@bikeberry.com ... (800)317-0479
I too am having this exact same problem.
Who is the competitor
It is a generic brand that is extremely popular and can be easily purchased on ebay. Many of these type of transmissions use this exact same transmission and simply re brand the product.

How do you open the transmission my screws are tight end breaking apart as I try to open them to get to the drive sprocket
Go to any auto parts store and buy an impact screwdriver, use with a hammer.
See youtube videos on how to use, they work wonders on loctited screws.
cool product 🌟🌟🌟🌟🌟
I ask about getting you gear box got no reply
👍🏻👍🏻👍🏻🌟 Tahan Tawa 🙋🏻♂️😁
And then you show a video of a guy riding with a 2 stroke that does not have either of these transmissions. :I
Would this fit on a 30cc 4 stroke?
As long as the engine uses a 78mm bell housing and similar bolt pattern, then there should not be any issue.
GOD loves y'all and have a Blessed day ✝️⛪🙏🙏🏻🙏🏼🙏🏾🙏🏽🙏🏿👼🏿👼🏾👼🏽👼🏼👼🏻👼😇🥰❤
