GY6 A and b case explained

- This is a video explain the differences between what is called A-Case and B-Case GY6 Engines. Some popular model numbers are 152QMI, 157QMJ and 161QMK and of the Taida 232cc (King of them all).....
In addition to explaining the differences of block, I detail how big each case can bored out.... I discuss short and long case A-Blocks and show video of the max tolerances and stock size case openings.
This is the perfect video for anyone that is considering a big bore kit but would like to know more about what fits what. - Auta a dopravní prostředky
So here is the question. I just put a 50mm cylinder/skirt/sleeve into my crank case, and it looked like i had a lot of extra headroom in the case if i wanted to put a larger cylinder in there. Is the limit of the bore kit you can put on these determined and capped off by what cinder skirt i can fit in there or would the cylinder skirt/sleeve being completely flush and tight with the crank case jack something up? It's a qmb block and it was stock 50cc if i can throw and fit a 150cc crank shaft and increase stroke distance exc and do some heavy modding and put a bigger larger cylinder in there that be sick. I just don't want to do any boring to the crank case at all.
How would I go about getting one of those liquid cooled 232 engines time to replace the 157qmj
Thank you for all of the great videos dan..i needed your help but u are so dam busy there is no way to talk to u...Larry from Indianapolis..
If I have a 50cc gy6. I don't know yet weather it's a long or short case yet. Haven't went out and looked yet. But would the 150cc engine swap right into. I heard the motor mounts are different. that's no big deal I can weld new ones. But everything else will be direct fit correct?
Im up tuning my 125 cc Gy6 cylinder to 180cc (63mm) What are the intake and outtake diameters I need to drill my 125cc cylinder head to? Also what size main jet you recommend for the default carburator of 125cc?
I have a question. I want to use the original taida case i have. But i want to put a 14 inch rear wheel how the 161qmk comes with. Can I switch over any parts to make that happen?
I'm having an issue with my build.everything went well untill I installed the cam.the cam is way to far the left and it hits the valve cover and rubs the rocker arm assembly.the cam was from another 150cc gy6 qmj but looks to short.have you seen this before.
Hey Dan I had a question maybe you could help me im trying to get replacement parts for a 2017 kymco mongoose 90s all I seem to find are 125cc big bore kits do you maybe know which gy6 parts will fit my particular engine or if generic gy6 parts will fit at all or if I need to try to order just from kymco I’ve also heard Kawasaki kf90 parts fit and possibly Polaris outlaw 90 but I haven’t been able to confirm anything my engine has a top end noise or possibly the crank and I really want to rebuild it for my sons birthday thanks.
Is there any way to put a chain drive pull set up on it or are there only belt drive
Wish this guy was still making vids. Wouldve loved to see what he thinks of ssp-g. B blocks but they look like taida
I have a 150 gy6 b case it has the bigger stud spacing and curved fins on the jug ..I can not find a big bore or even a stock replacement head anywhere ???can u get me a big bore for my motor ??
Thanks Daniel ...I thought that might be the case😊👍
Can the crankshaft for an A-Case engine be used in a B-Case engine?
i currently have a cheetah baotian gy6-a 50cc and its upgraded to 47mm piston, I also have a gy6125cc motor with a 12 intch wheel.The answer is:can i swap them?
i have a new engine with a id plate that reads 161qmi can u tell mw what is the largest bbk i can install twithought boring
Can you please explain for us everything about the so called,
1P61QMK-B2 engine as there is no information about this engine to be found anywhere?
I really need all the specs and info on this engine I can get as I messed up and bought one thinking it can be bored out bigger and have the head wrapped with a copper tubing with tiny radiator and 12 volt water pumped cooling system?
How do I find out what Big bore block I have I have IceBear mad dog all taida motor.... The Piston is a 67 mm piston 57 fit spacing with a t300 cam shaft....was told it was a 232cc the head said fit57 63mm with chain 92...does this make it a 232cc?
I have a 180cc from a China quad the numbers stamped are as follows....AT80-003420 can you tell me what engine it is I'd like to add some performance parts but I have no idea what type engine it is please help if you can Thanks for your time
You're quite the whistler my brotha! Loved your video. Won't be joining your forum because a page forces you to add junk apps to join. No thank-you
the head and valve cover are exactly like the 4 valve shown in this motor just with a stock cylinder not the one pictured.
Specialty orders means no refunds!! Weed out the time & money wasters!! Good video
hi there
i was wondering i'm looking to buy parts to start building 232cc Taida Engine
with all the high performance 8200 stroker , liquid cooled , 4 valve , and all the rest of the parts i need to build me a custom monster gy6 Ruckus.
can you help
Wats up enjoy your videos really great stuff.i have a? Have you ever messed around with a ttrmc+14 107 rod crank with a 4v if so could you give me some tips on it.the only thing I see so far is milling the piston and chain length just asking thank you
I have a 161qmk-b2 and can't figure out anything on it. I can't figure out what I can upgrade or do
What's the original case size unbored?
Have you ever came across this motor block 161QMK long case engine are they good motors
Hello great video i dont mean to be a bother yes i do lol im looking for a short case left side crankcase for a Hammerhead 200 w/internal reverse would you know where i could find one the number on the block is 157qmj thank you
I have a GY6 171 CC liquid cool engine it comes stop Stone Age Sims moped motorcycle could you tell me what kind of block it is cuz I was like to build me one but I want to start with the best that way I mess up not the block
Sorry mine is 61qmk a block. What is the highest cc i can upgrade to?
Hey Daniel
Too bad that guy left you holding the bag and screwed it up for the next person, some people are like that everywhere they go. Next time get the money first, most serious people won't mind . I appreciate all your info and help.
Thanks
I bought a Sims moped motorcycle he's got a 171cc they call it a 200 HD do you know what kind of block it is is the four valve motor
I have a genuine buddy 170i how big can I bore the motor
I've got a question about the 4 valve motors. I have one its a qmb 4 valve oil cooled 150cc like the one in the video just stock. is that in fact the same motor or what can you tell me what I have if its anything at all.
A QMB is not a 150cc and I have not seen a 4 valve kit for a QMB (Not saying there isn't, I just haven't seen one).
The "QMB" is actually a 139QMB or 1P39QMB... That is an engine stamp describing some of the engine specs...
1 = 1 cylinder
39 = 39mm cylinder
Q = Cooling type - Q is Air
M = Motorcycle / Moped
B = Engine size (B =
Seeing if you had an idea I got a big bore on a 50cc got fire and gas but will not run check timing it look good
Great tutorial video I have a gy6 150cc long case 157QMJ I'm installing a 180cc big bore kit for a 157QMJ 150cc but the cylinder skirt doesn't want to ease in easily the cylinder skirt definitely not going in easily what is the correct cylinder housing to make it fit? The kit I currently have now installing is a 63mm not fitting by that I mean the cylinder skirt is difficult to slide on but everything else fits perfectly mint?
Converting to a 180cc uaually means youre using a 63mm piston, you must bore the case block....61mm is biggest you can go without case mods.
@@dmartin925 okay thx Daniel I really learned something today!
Excuse me your correct I meant qmj but no i pulled the motor out of a touring 150cc scooter its a gy6 style not qmb, but the style of the qmj its a factory 150cc 4 valve oil cooled motor of the qmj style just 4 valve I have kept it only cus its a 4 valve and I have never come across another to this day.
What is the maximum size for a 50cc short case ?
Hey is there a kit with all the parts for the taida 232cc Gy6 B long block 4 valve watercooled motor or do i have to buy the parts separately
Hero Hersey check the gy6 store
what is the difference with a QJ 157 I'm so confused I liked the video thanks
Hello I need help what engine TGB bullet 125 have I need to order top end rebuild kit

Hello sir.. wanna ask you about Suzuki AN150 (157QMJ) engine.. what type of the case?? Is it short case B or what?? Can i upgrade or modify using any gy6 performance part?? I want to make it go faster.. 🤣🤣
Hi Daniel...excellent video as usual..first thing..thanks so much for explaining the magneto output to me...I learnt something there👍...now my question is this ..can I put a big bore kit in my fuel injected GY6 (yamaha cygnus twin port)...many thanks😊
+versatec1 Hi Vers! Thank you very much.
Unfortunately, I do not know your specific model of scooter. So I can not say for sure.
What I can share with you is that modifying scooter cylinder that has fuel injection is very hard to do.
When you go with bigger piston, you also have to upgrade the amount of AIR and Gas the scooter uses and have to modify exhaust for new flow rates. Getting fuel injection to add more fuel is difficult to do and requires expensive modifications to the ECU (computer that controls fuel flow rates)...
You would need new fuel Maps, possibly a bigger injector, the list goes on and on.
Sorry I could not give you exact answer.
+Daniel Martin. im wondering where can i get a case bording big block for a gy6-65mm
How do you decode a gy6 that dose not have a model like qmb or others
Hey Daniel,
Thanks for the great video. I’m hoping you can help me with some info. I have a customer with a 161QML ... he needs a variator but we discovered the crank is bigger than the standard GY6. The 161 crank is 17mm vs 15mm for the standard GY6. I have found zero info about this and cannot find a variator. Anything you can tell me about this would be appreciated and if you can point me to a supplier for the variator I’d be ecstatic... Thanks, Josh
I can see he was right on time with a response. lol I dislike people that don’t respond to questions that they could help with
How can you tell without opening the motor what you have. Yonghe 150cc on engine tag can't find anything about it specifically?
Yonghe is a Chinese name
Kymco super8 is it b or a?
How much are you selling for I have a 150cc gy6 but looking for something a little faster
how much for your top dog engine there the 232cc all taida? I'm pretty sure you wont sell the 232cc and I need a short case btw, how much for the one that guy from new york didn't want?
+Carlos Villarreal Hit me up at my forum: www.dansgaragetalk.com
Will a drop in NCY 171cc big bore kit fit in a 1p57 qmj engine?
i believe the ncy 61mm bbk will fit the gy6 a case with no problem. others like the naraku and taida, those are hit and miss, but it all depends on your case. some gy6 a cases are odd balls from what i read. some could have the 63mm opening, some could have 63.3mm or even 64mm. the only way to find out is to disassemble the top of your engine and measure the cylinder skirt and case opening.
The only difference in a "p" engine, is they have bigger head
well same valve cover with the 4 valve print
How much for the whole case
great video like them all... how do i order parts ? there is nothing on your website
+raddddix Thank you for the kind words! Glad ya liked the video.
Visit shop.martinmopeds.com ... Were are in the process of uploading our inventory to the net.
What is your website to your store
What's the biggest you can put in a block without any boring
Engines(even these) are high tollerance items. So the answer is nothing bigger than what's in it.
If anyone out there has a performance case that the transmission side is ruined I would be interested in that engine. I want to build one of these or find one that's built and the transmission side is damaged I'm going to cut it off anyway.
hi, will the 58.5mm bore and an outer sleeve of 60.2mm and fits a 125cc?
Yes.
+Daniel Martin thanks for the fast response. Im planning to upgrade mine.
On an engine like yours, you can go up to 61mm if you select Taida or NCY.
I have in stock the Taida 61mm no bore if you're interested. I also have 58.5mm BBK's in stock (Glixal and Taida)
+Daniel Martin Thanks I'll check that out. I have one more question again. What valve clearances would you recommend on my motor
Hi Martin, is this the one that you recommend to my 125cc gy6, 61mm no bore shop.martinmopeds.com/X06-Taida-GY6-Cylinder-61mm-Big-Bore-Kit-Case-mod-not-required-GY6-01061-w.htm if so I need your response. Tnx
hey how can i contact you for buisness. serious.
Hola amigo, me gustaría que tus vídeos tuvieran subtítulos en español.

I didn’t realize Herbert the pervert made CZcams videos
If I gave you a sandwich, could you get Chris to fart on it?
so how much you selling those 4 valve 232cc?
shop.martinmopeds.com
Is the 157qmj an a motor or a b motor
Its an A block
Do you need a Motorcycle license in FL if I get one of these?
David DeBergh yes. 50cc is max amount without a license and registration. if you go over 50cc it needs to be registered with insurance and you need a license. I know it sucks.
Just to add to this, and make a correction you do not have to hold insurance on any motorcycle in Florida no matter the cylinder size as long as you wear a helmet. I would still carry liability though because you never know what could happen.
I emailed you about some info on a motor and haven't heard back from you
Did you get an answer
good video but if someone is advertising a engine as a 200cc but it's a 169 then that's false advertising i have a taida 170cc big bore kit i know i will be at 163.4cc so you might not want to say it's not false advertising when it is other then that good videos
+ThEoThErGuYz757 Ultimately, If someone is selling a 161cc as a 200cc, then sure, I suppose it is. What I was talking about is intention. These 200cc engines are marketed by the manufacturer that way, they're even sold on mopeds as 200cc's, but they're not. So, when they hit the US market and sellers are provided the false info, I don't think the end seller is misleading people on purpose, as they were also mislead...
It does become intentional when a seller is made aware of the fact and they don't change the ad or add a disclaimer...
I do not sell these "200cc" engines, I was only pointing out the info errors.
+Daniel Martin i hear what your saying but as someone who would sell an item like that wouldnt you do your own research to make sure everything is what it is suppose go be before advertising something? as for scrappydawg or whatever they know they arent that cc but still sale then as that which is false advertising not saying you per say just stating facts...just cuz something says it does this or that doesnt mean it doesnt that thats when research should be conducted to make sure accurate information is given out
Would it be better to stick with a 150cc for durability than a 157cc?
I sent you a message on your website
Hi Daniel I love what your doing !! Very few people knows what is going on here with these motors , I am doing all kinds of mods on a motor like it , lifan 140cc and the YX motor , case welding and make a 76mm piston work ! Check out all my video's you'll see things not done before I am into drag racing with this small motor . My channel m42665 -- copy a paste ( Crankshaft balancing static motorcycle pit bike ) I'm the only one doing this .
WE MISS YOUR VIDEOS.
Your "S" sound so sharp in my ear and it hurts

If you still have this motor for sale, please message me.
For the amount of money spent to hop up a 150 you could put a sport bike engine on it or buy a sports bike lol
People will find an old camero or trans-am and drop 20-30,000 into it...for that kind of money, they could buy a brand new one...some would say it doesnt make fiscal sense.... it's more about the love of the project... people get these Chinese scooters and fall in love with it, but they dont fall in love with the performance... that's why they upgrade... they know they could just buy something fast, but they love their scooters and want it to go fast....
Sorry that’s false. Most people buy there scoot because they are cheap and can’t afford a larger bike. They put the standard performance upgrades because they are cheap. Very few people and I mean very few people will drop three grand on an engine for their scooters what’s the point of building and boring 150 cc engine, when for the same amount of money in relatively the same mounting dimensions for 350 or 450 mL engine from a different scooter and have way better performance in better reliability I’ve board many blacks and I’m sorry as thin as you’re making the walls on those oil passages that is a recipe for disaster. Example I have 150 mL GY6 buggy from yerfdog. I did the whole pouring beers and got it up to 180 ccs. Just last year I bit the bullet and bought a wrecked 250cc gy6. And that 250cc GY6 blew the doors off of the 180 and I had significantly better reliability and performance.
