Thank you, for putting these videos about assembelling the motors i realy learn a lot and just sucsesfully changed the cylinder head from my gy6 150cc .
This video was awesome and very very helpful. I’m new to this hobby and I definitely enjoyed watching/learning how to put this engine together. 👍🏻👍🏻
Glad it was helpful!
Old guy here.. just noticed stretched ruckus in my feeds and started looking around. Presently Im like 2or3 miles from work and figure it would be great to use and leave the car parked. But, man this is one deep rabbit hole. A fun rabbit hole.. but deep
Lol true story! Big rabbit hole
Awesome video!
Hi its Jimmy just watch your new build and could not have had a better exsplaned in detail nice and slow pace easy to understand what you are doing . This session of your build would be nice to send to all small engine repair college to show and tell class.
Great video brother I really enjoyed it buddy
Hey man, great Ruckus idea for you. Build a hybrid ruckus. A hub motor up front with regen capabilities. Change the twist throttle to two thumb throttles that can be pressed simultaneously or individually. One thumb throttle for the engine and one for the. Motor. Another thumb throttle on the left grip to activate regen. battery pack and bms under the seat. The hub motor will really give you the torque and power to merge and move around in traffic when it’s is needed. Can add to top speed when needed, and will increase the fuel mileage also. I’ve been wanting to realize these ideas for awhile but you have the resources to make it happen. It’s the best of both worlds. Would definitely be helpful on a GY6, but would really shine on the stock ruckus crowd.
i like this idea man
This would be sick
Watched this again after purchasing a1p57qm project bike (boom brand, like a rugged) and I can't wait to get into the build. This video is awesome in an auto tech built lots of performance car engine no bike motors though but I can see it's the same just way smaller scale. More i just gotta test mine apart. Doggie or what HAS to be done and then plan the build. I can't afford this compete set up but I'll probably do some of your upgrades. And buy my needed stock replacement stuff from you if I can.
This just a needd ,for my scooter gy6 150cc is upgrade rigth now is a modificacion 171cc ,and you help me for the instruccion is a perfect, thanks bro !!😎😎😎 saludos desde Mexico ✌🤟
Great to hear!
nice video. watching from the Philippines
Thanks for the support
Now I’m having a Mikuni round slide carb, better clutch installed, and I’m porting the head! Hopefully it rippss
Why port the head?
@@A_Stereotypical_Heretic to get more air in it and more fuel so you get more combustion and hp.
@@A_Stereotypical_Heretic it ran really good and I hit 44 mph but yesterday I must’ve melted the piston. It was smoking and leaking oil through the exhaust.
@@cn9936 probably because you ported the head
Probably because these engines are garbage.
Bro I’m ordering from you every time!! Very informative!!! Ordering the big bore next time I put on road !! The 200 plus kit fit on a Ruckus??
You remind me of Rich Vos for some reason haha thanks for the video though. Im about to go all in on these little motors.
FREAKIN Bad ass!! She does rip!!
Getting the monster big bore kit back in stock for the qmb139 any time soon?
I love you guys! Best info, best parts!
Do you have (or recommend a source) a bolt and stud kit for gy6? I am installing a 47mm cylinder and head combo with 69mm valves in my pony 50, I'd prefer to upgrade the hardware too from the chineese bolts and studs.P.S. I'm not afraid to tap for larger diameter studs!
Sweet
thanks
Fits great, glad I bought this kit!
nice
Are you lining it up with the T or the line next to the T, in the video you mark it with the sharpie but the close up picture doesn’t show it marked
I have 125 cc GY6.Does changing to 160cc make more fuel effiecient also faster?
Do you make a kit for the icebear maddog 50 to 150, I can’t really find anything on it and want to swap it with this 171 kit
I’m trying to do the same thing
I've just bought your 171cc cast with cam. I have a ncy cvt kit. What gram roller weights should I run so I can easily wheel I also have a nibbi pe28mm
What is the top speed of that blue bike up here in Colorado? Thanks!
I have a question.
I have an Ajs Modena with an short cast GY6 125cc engine. With factory EFI.
I want to put an 150cc barrell and piston on but I think it will run to lean. Should I buy 150cc ECU.
I installed your 171cc Pro Bld kit and followed your video step by step, but after tightening the rockers down the engine will bind a little bit then turn smoothly until it comes back around and binds up again in the same spot. What's the possible issue(s) it could be?
Bro. Idk if u already have this kind of video. If there is , please link, but if not, please make a video of it.
Regarding about the combination of flyball/slider ball ..
It is confusing to tune up that thing as this is my 1st time getting a scooter/automatic.
Thanks again how will I get the parts order from you
Do they make a metal battery box cover for gen 1 or 2?
Very quick. Strange high pitched squeel coming from variator at idle.
so whats the ticket to 80mph on my mad dog?
already 150 swapped and the complete ncy variator/clutch kit on the way.
28mm carb, and exhaust. can i find it with the 171 kit or do i need to go bigger?
ready to spend the money on your site!
Is the qmj157 just the stock 150cc gy6?
At What RPM should my 171cc idle??? I'm in AZ in case weather and elevation matters.
I forgot tell you its till back fire because old exhaust muffler got built in catalytic converter! Do I need get same thing 🤔 or not? Matthew
have you tried working on Kymco Super 8?
Hello from new Britain Connecticut, I have a NCY 171cc kit with 61mm,11grams roller and racing clutch,30mm carburetor but I don’t run more than 55mph, I want to gear up what is the best gear you recommend for my upgrade.
Bro we should ride, I live in Bristol. He has a gear up kit on his website I ordered it. You choose what type engine you have and if you want it pressed or not. I got mine pressed a little pricey but worth it. I haven't installed it yet.
Will this go in a sym jet 4 2015?
Very nice video
Thanx..
Let me ask you a question..
What kind of engine the honda navi have..??
Thank you 🛵
Would I be able to get a GY6 171 short case engine for my bintelli flash scooter?
Ignorance is bliss. Public school is 💯👩👩👦🌈🧑🏫👩❤️👩🧑🤝🧑😷😷
I have the Maddog Rukus, could I use this on the Rukus? If so how much is this kit???
Hello is there any kit for my 2013 metropolitan nch50 for a stretch kit?
Can I put 65mm piston and 8.2 striker on a block engine 150
Can we get flow bench testing pre before pro.
Hey Matt...do you know the sizes of all the bolts for the shrouds? I had to order shrouds and unfortunately they didn't supply them.
Not off the top of my head :-(
Damn...alright thanks I'll ask around
hello, im from malaysia. My question is do you ship to malaysia?.. interested on the 232cc engine
Hello I'm thinking about getting a Honda ruckus quick question though is the dy6 the only motor you can swap in it
You can do a zuma 2t motor as well that has supported parts for the swap
Bro is this engine is it on your website because I am highly interested in buying it at some point in time brother
Hello i would want to ask a question about performance parts on a 50cc taotao 4 stroke engine , i have put on a : 80cc big bore kit , yellow center spring and springs (1500 rpm) for the stock clutch and malossi rollers i also have ordered main jets for the stock carb . Next i wanna do malossi multivar kit (variator kit with rollers , center spring and sliders) and a malossi fly clutch kit (clutch and bell), what should i do next after the malossi parts ?
Thanks
Get a bigger carb instead of the jets, will make it way better. Don't go to big though for 80cc 18/19mm is more than enough
@@daantuin3351 the stock one is already 18mm , i will see i want to put a 20mm one but time will tell
Do you have parts for the 161qmk or know where and what fits?
Ncy Store sells parts for that.
How much for top end oil pump is the 180 a puch in and
Always better to go forged, the cast can crack easier
Please, brother, make a video for us about the piston and about each of the rings, including the oil ring, and thank you very much
Done! :-) PISTON RINGS

I just upgraded big bore kit and cam
Engine revs nice and good power
But feels like in need more gear
Ore higher roller weight in cvt?
What you suggest?
You can do a gear up kit:
www.rollingwrenchdenver.com/products/gy6-gear-up-kit?ToPasteboard
@@RollingWrench ore go higher gram on roller?
Also....is this just a stock chinese crank with stock bearings and rod or is the crank forged and with heavy duty good brand bearings and a forged crank? Seen lots of bottom ends roasted from the 171 big bores and wondering if this bottom end has been upgraded to give long lasting performance? The extra impact from the added power and compression I believe is whats bending rods on the Chinese gy6 150cc engines
I haven’t ran into any issues with the stock crank on a 171. How ever upgrading the crank will only improve the longevity
I need a battery box for a Maddog, where can I get one?
Transmission serial number is YN173MM. Website says it’s supposed to go 70-75 mph I can’t get over 50mph. Please help
I got a project go Kart that has low compression, would just going a big bore kit be a better option than just 'stock rebuild'?
Great idea
@@RollingWrench I can't believe I got a reply. After watching your videos for weeks, I'll be grabbing your kit to solve this issue. Great stuff and excited to keep building!
@@TheBeardness thanks for the support 🙏🏻🖤. I love this stuff
Dude I would just like to buy a built engine that would fit my 50cc chinese moped do yall have something like that?
The stock GY6 150 is around 9hp and 12lbft of torque. What do you think this is rated at?
I can only guess. But I will say it feels like double the acceleration. Top speed doesn’t change much since it’s not geared any different. I will do a comparison with real acceleration numbers and top speed numbers soon.
I thought the rocker assembly was bolt size M8 which is 7-11ftlb. And the rating is by bolt not nut size.
Ey listen me. I have a 150cc GY6. Do you have a kit to make an upgrade to 180cc?
Hey I’m trying to figure out what to order I want to change the stator in my gy6 ruckus should I order the 11 pole kit or the 12
11 pole would be best
Thank you for replying I’m going to order the 11 I checked connection last night and you like always have the best option it’s for the gy6 qmj157 thank you again
I'm waiting to order the monster 90cc big bore it's unclear if my current valve length matters on my dongfang 139qmb 50cc considering the kit comes with a new performance head does it matter or will the kit simply drop in please get back to me so I can hurry and order the thing already I'm sick of hardly hitting 35mph
It only matters if you reuse you current head, otherwise no
Could I do this to my 2006 tank 150cc
hi what cc is a qmb-b thanks jhn
So what's the actual total power output of the 171 with this cam and big valve head?
I haven’t dynoed it. But I think the ultimate question is how fast 0-30 / 0-60 and top speed. I have a fancy device that measures that. I’ll have a video out soon
@@RollingWrench I used to have a Gtech meter way back in the late 90s that used accelerometers to measure g forces and 1/4 mile times, 0-30/60.
They probably make something much nicer now. Lol.
Very nice engine kit you've put together. This will hopefully make a lot of people happy.
Can i use a long case on a scooter that has a short case with out any issues of mounting to the frame
No unfortunately. The shock will be an issue and the look woul be different
can someone help me?does removing egr can really improve performance?thanks
It won’t improve the performance at all. It just cleans the motor up visually. And it will fix the backfiring at decel. It’s nearly impossible to tune with the EGR installed as it introduces fresh air into the exhaust
That's crazy the build kit cost more than the scooter if you got a Chinese scooter as people call them That's about like the people that putting stuff on a gun that cost more than the gun but hey if you got the money and that's what you want to do go for nice looking kit how much more speed do you get for a over $1,200 and something $ kit
How much power do these roughly make after the 171 big bore kit?
16hp ish
Hello bro.
I wish reveno clutch 4 sent mexico city.
That’s posible?
👍👍😁😁
So, could I remove the engine on my 2009 Kymco People 50 2T (Two Stroke) and replace it with this product?
No. It wouldn’t bolt up
How many this set ?
I have a 150cc gy6 I would like a kit that I don't need to bore the case you have a kit that gives me more out of the engine with out braking the bank
$1200.00
Sure I'll pay for that!
For $0.50 more, may you put all the hardware(screws)into individual bags and label them by component?😆
When I'm ready to build a Turbo Ruckus, PROBLD will be my way to go. You do excellent vids and I've seen other YT creators into the scooter scene use PROBLD parts in real world.
Living 5000+ miles West of Cali, it never snows, so it's scoot-scoot year round!
It never snows in Winter/Spring it rains. So it's scoot-scoot approximately 10.80 months/yr!
Niiiice!! I appreciate your support 🙏🏻💯
Do you guys sell the bike already built
No. I have someone that can build it for you if you want
How can I order the hole 171 Big Bore Kit it I'm trying to get the parts to build it with but I need help on ordering the right parts
I have everything linked in the description. The top end by its self or this kit. You can choose
Ok thank you keep up the great work 👍 👍👍👍
Congratulations with your zesty rpm revving Big Bore!
So I’m planning on buying a 50cc scooter in a couple weeks. I’m only buying 50cc so I don’t need to insure it. I weigh about 300lbs, and I’m 6’4. How much speed could I get stock? I’m planning on using it daily to and from work, less than 10 miles. I have a feeling I’ll need to do a big bore kit, but am definitely buying from you guys after seeing your videos.
Ya you will definitely want a big bore kit. I recommend this kit:www.rollingwrenchdenver.com/products/90cc-monster-big-bore-cylinder-kit?ToPasteboard
@@RollingWrench does that still come with the piston rings pre assembled? I noticed in one of your videos they did, but just want to double check for this set.
@@jr.gamer3219 yep :-) it comes exactly like the vid :-)
@@RollingWrench awesome. Will possibly be buying in 2ish weeks then. It’s a drop in too right? I didn’t see if it was or not in the decription
@@jr.gamer3219 sweeet! Ya, it’s drop in
Can i upgrade factory fifty 50cc gy6 engine to 172cc by using the same kit? Brand/Model is Kuba/bluebird
No, they are two totally different engines. The 50cc mounts from the bottom and the 150 mounts from the top
How long before you can do the EFI kit to go with the 171cc kits ? & will you post to the UK 🇬🇧
EFI is gonna be bit…. Maybe a year or more
@@RollingWrench I'm guessing its not straight forward to go from EFI to carb with all the electrical stuff 🙄
@@keithgreatbanks I have never tried it, but I’m pretty sure I have a tuner that will work on the new gy6 EFI systems they have been putting in the Chinese scooters
@@RollingWrench well that's a step in the right direction for me, you know you are going to have to make a TH-cam video about fitting one for me now 😉 keep up the great video and thanks for your time in replying,
Hey so I have a super hornet 150 cc I’m 99% sure its a gy6 long. Can you maybe help me confirm that?(I can’t find your old video on it been subbed awhile) My dad was the one who got me the bike and he told me about getting this and doing it with him a couple months ago. I still want to do it but I have to do it by myself though now because he passed away. I’m sure he would have been hype to do it with me. So I just want it to be my summer project and as something he’d have appreciated and loved.
Here ya go :-) th-cam.com/video/zdrwJb8MLHI/w-d-xo.html
hello there i really enjoy your videos that you put up of the gy6 engine , i have sent you an email about buying a modified gy6 engine from you , but i didnt get an email back from you , do you build engines complete ready to bolt in please , if you could get back to me thanks from byron
Hey dude, no. We don’t do any customer work, we only sell parts. I can put you in touch with an engine builder. Email us. We are off on the weekends and Mondays are cra cra. So be patient
I noticed you never use anti seize. While working on small block Chevys, I was taught to use anti-seize on any steel bolts that go into aluminum and exhaust bolts. Just wonder why you don't.
The main reason is these are not out in the element and are not exposed to the winter road salt and such. It’s never been an issue.
Why will a cast piston last longer ?
Forged pistons expand more when they get hot. They have to design them so that at cold start temperatures the piston is excessively small. It will slap around more until operating temp is reached. Cast doesn't expand so much when hot so the cold clearances can be designed tighter.
Forged is generally only recommended for high rpm or turbo stuff. Here I would think it's mostly unnecessary.
Take a shot every time he says "this sucker"
You better not. You might not make it to the end of the video. Lol
I bought a Chinese bike they said was 200cc but the displacement says 168. Is that considered the 171cc?
That’s 168cc. They market it higher than it is. The 171cc big bore kit is to upgrade a 150cc engine. I just did that!
@@MiguelLopez-sj2ib 168cc speed 120km/h ??
@@MiguelLopez-sj2ib my Sym duke gy6 168cc made in Taiwan since 1997 ,video th-cam.com/video/D6o6QvLh7XM/w-d-xo.html
Will give you an extra timing chain, but you only get 2 g clips.
Do you need more in the kit?
@Rolling Wrench I haven't ordered yet, but will be as soon as I get a gy6. I was just being silly because you know how far those clips fly. Great video. Great customer service.
I have the Vitacci Falcon 250, HELP!
Why can’t you just fabricate the engines and sell them pre-fabricated and everything installed options so it can just be pluck and play
I just started this vid I really hope this is something I can buy an somebody is selling an I really hope you can show how to put this shit together an can teach if so I will subscribe an like your vids an be here for more knowledge if you got wisdom brother I’m hoping you are.
How CAN I T ONE
I have iceberg
The shroud shall be Chrome
They have them :-)
What's the cost ?
www.rollingwrenchdenver.com/products/gy6-171cc-builder-engine-kit-long-case?ToPasteboard
I’d pay maybe $550 for a fuel injection kit for a gy6. No reason it should cost a penny more since one for a v8 would only run $1k. Everything on here is a lot for a little gain and still no additional top speed. Faster acceleration seems to be the only major change.
Sounds like you will be running a carburetor:-(
How are the dimensions of the head? Is it fatter? Reason I'm asking is because I don't have much room on top of motor on the gen v maddog. My efi kit fuel injector is super close to the under seat pan as it is. Let me know dude!
Nevermind on this question, I see you still use the factory plastics, so it must be the same. Mahalo
Is it true that the GY6 kit are all cheap Chinese parts?
eBay and Amazon yes. Our kits are top notch from Taiwan.
@@RollingWrench I suppose I have to buy a new or used ruckus and convert. It's hard to find one you can buy in FLORIDA
I gotta blow the 49cc first!
