This is by far the most detailed and helpful rebuild walkthrough i've seen on youtube.
i agree i dropped my bike to a mechanic hes had my bike for a couple of weeks .. hes charging me a grand for a job i see kids and home garage mechs doing in 4-5 hours on youtube.
Check out 49cc scoot on CZcams or 49ccscoot.com online
About to do one soon, 100cc, and I'm watching only your video. You're a good teacher and your voice isn't annoying like alot videos I watch
Those kits aren’t actually a hundred cc’s. They’re less. That’s judging a marketing gimmick.
This video saved my butt!!! I couldn't find ANY OTHER tutorial on youtube or else where. I've never worked on an engine before and had no idea how to even start. BUT, I played this vid a step at a time in the garage while I worked on my bike and everything went perfectly!!! I could not have installed my bore kit without this video, thank you so much for being so thorough and simple!!
I installed an 80cc bore kit on a Dongfang DF50SST thanks to your vid!
Not sure if i've commented here in the past, but even if I have, I would like to reiterate my opinion on this video and the author of the commentary.
This is the most comprehensible step-by-step installation of a Bore Kit on a qmb139 engine that i've come across. As you've also stated in the video, you've done this many times and get overconfident; however in other tutorials it seems as though they skim over tiny important details because of that overconfidence that you seem to explain very well.
Crucial information for beginners and seasoned professionals alike.
I used this video as a reference for installing my first Bore Kit, and she ran wonderfully. I will use this video for further kit installations.
Thanks, Rouse Garage, for being so thorough and taking your time. Teaching is an art.

Thank you for the kind words!!
Agree 100%!!!
@@cecileverone953 can you please tell me how 2 order the parts
@@ronathey5287 I ordered my 80cc Big Bore Kit from Amazon. I got it 2 days later, and the kit had everything needed to install for about $30 bucks.
Hey man. On my cam the top is past the edge of the head .why?
I just wanted to say that you are greatly appreciated, I jus bought my first 80cc big bore kit and followed your steps. Like the other person said, you take the time to go over everything and not overconfident like the other people. I will most definitely be using this video as an reference.
I followed your step by step installation...
Dude I hit 51 top speed...thank you so much....my scooter is so fast and super strong. ..you absolutely awesome dude!!!
Did you use the stock head, or did you have to upgrade it? I bought the 52mm bore piston and jug, but the head is stock and too small (piston hits the head at TDC)
I just want you to know I just finished rebuilding my scooter engine with the help of your video. I have never worked on a gas engine. With your video, it really went smooth. Thank you so very much for explaining ever step you took.
I used your video to install my kit, Ive been running my it for about a year and its running fantastic, Thank you for your help!
Awesome! Installed my kit with my computer nearby and this video on. The install went super smoothly and the bike fired up first try. Thank you for a great video!
Thank you so much for the step by step it I ordered the board kit on Amazon for like 70 and I made sure watching your video the first three times that I had all the pieces I may be watched your video total of 8 times from beginning to end not skipping anything thank you so much I am the President of headless horseman bicycle and scooter Club thank you
Absolutely great step by step instruction, thank you!
This is the best video out here!
Detailed oriented. The most comprehensive. Thank you for it rousegarage!
And I just know with your step by step video then I'll have no problem you're the best teacher that I've ever had shiny Apple for you😊
Excellent video. I watched this a few times and was able to install the big bore kit with no issues. Thanks for the information. Our trike moped went from being a turd to being able to go up hills without any problems. The big bore kit was the ticket and this video gave me all of the confidence that I needed to get the job done. Thanks again!
What’s ur top speed
@@tylermeller7581 it will be around 70kmh to 80kmh
I had already ordered a 100cc BBK, 20mm carb, perforamance cam from an online source and then discovered this video. Excellent vid.
I have a 2009 Tomos Nitro 50 and the sleeve of the new jug wont fit in the crankcase. I need to get out my die grinder and make
the bore hole larger to accept new jug. Wish me luck. Heads up to anyone before they start assembly.
just wanted to say thank you just installed a Big Bore Kit just like this and this video made it really easy
+Paul Hyde
Thanks for watching!
did you add any performance up grades as well or just the bore kit and how much gains?
You wouldn't be able to do a rebuild video for an XT600? Haha
But seriously, good vid. I just installed a big bore kit on a 2 stroker. Had to freeze the gudgeon pin so it'd shrink, and even still it didn't want to go in. Nightmare...
Are a v dubber? I saw ur profile pic
@@RouseGarage I have installed a 100cc bore on a 2018 taotao vip. I had no spark at first thinking the timing was a little off. Played with that and got if running. Now it won't fire and the valves seem like no matter what I set them at. The seem to work their was extremely tight. Any ideas
Thank u for this video. I installed an 80cc big bore kit on my taotao vip while watching ur video step by step. I am no mechanic but this detailed video gave me the confidence to do it and everything came out perfect!!!! 😁😁😁
This is an awesome video that shows every single step you need thanks so much for this great video
Excellent video. My only recommendations are to also use assembly lube on the camshaft to avoid a dry start, and avoid getting any sealer near any oil passages. If sealer makes its way into the oil system, it will ruin your day.
Hey, I wanted to thank you greatly for posting this video! Definitely the most comprehensive set of instructions I have found. I just performed the steps on a Kymco 2023 super 8 50x. They were pretty much identical with the exception of the housing had one extra bolt. Otherwise, it was spot on. I ended up using a zip tie to keep the chain safe and one mistake I made was not pulling the chain far enough out when I was trying to push the assembly back together. So the chain got caught a little bit nothing happened, but, just caution for anyone else when they were putting everything back together. Again thank you very much for a fantastic guide!
I also lubricated the cam before I put it in
Thank you very much from France :-)
the best tutorial on CZcams to install a big bore kit .
Best instructional ever.
Great video. Thanks for taking the time to share. Definitely increases my confidence level being a non-mechanical newbie. Thanks!
Followed your direction and the job went smoothly. Cheers
Thank you for going above and beyond to be sure we can see what you are doing every step of the way!! That is soooo rare in this type of instructional video...
Great job one thing I do is turn engine over by hand to make sure it's all free with no valves hitting the piston.
Great video! It inspires confidence in getting the job done right. Thanks.
Thanks so much. Did mine last night... having so much fun pinging it around town today.
It doesn't get much better than this. Thanks for posting!
Thanks for watching!
Great video! I followed along and it made the whole rebuild a breeze! She started up first try, thank you!!!
You are a great teacher man. Thanks for being so informative.
Wow probably the best most detailed video of this install I've seen, I really appreciate your help with this because I'm a car mechanic but had no clue about these smaller engines! Am looking forward to doing this with my 50CC I subbed and liked the video. 🤟
Crystal Clear Instructions..👌
Thank you my friend...🙏
Just the video I needed
+Rouse Garage , Wow, you are Very Good at making how to videos and are a great teacher. I bet I could even do this now. Great job, a joy to watch, and I learned alot. My 50cc YY50QT20 sat for eight years and I finally got it running (new petcock regulator and carburetor) and a little paint and Armour All. Thanks
awesome video, you did a really good job. I'm looking into an 80cc kit soon.
Just done a lexmoto fmr 80cc big bore rebuild using this video excellent video thanks again couldnt of done it without your help 👍
Hi Rouse! Great Tutorial! Congratulations!
This is by far the best video on CZcams about this 👏
This is the best video on CZcams I'm telling you bro this is spot on I think I could do this now thank you very much for taking your time to show people like me I'm definitely going to try this now I'm tired of people passing me on side streets lol
Thank you ever so kindly... your video was most enjoyable to watch and was worth to me your weight in gold. In my opinion you Sir are the very example of why the world is a better place by the sheer fact that you are in it. Please keep being who you are, you've restored in me HOPE that there is at the very least "one" kind and desent Man still willing to help, may the blessings of the Universe rain down upon you and yours always
Excellent work brother, GREAT video and tips along with patience. Grateful!
great video , keep wrenching
Thanks so much Patrick for this video. with your help I was able to install a 100cc bbk on my son's 49cc scooter. This is my first time doing this but thanks to your video it went pretty smoothly and we finished it up this evening and after a couple minutes of starting it, it fired up.
@Scott Dee without changing the gears 55 to 60 on flat surface which is plenty fast enough.
Do you remember what parts place you got the 💯 cc from or does anyone know where I can get quality instead of cheap China. Gone through two heads on this Moped motor.
I would have originally said go with rolling wrench, but with zero response to email info requests I'll DEFINITELY look elsewhere, if a business doesn't care enough to reply to emails then they dgara about customer service. UPDATE: Rolling Wrench is Just 2 people so response times may be extended.
@@JA-fn7le rolling wrench is a joke ...they charge 8.99 to download a video on how to install a big bore kit
The laws on these scooters are different in every city it seems. Union city NJ there towing them. Saying there not street legal.
Best a well-thought tutorial I have seen on the subject. thanks for your time and effort.
Awesome video! I have never left comment on a video before but it felt very compelled to for this one!! Everything was explained perfectly! Very easy to understand. You made this whole process easy and stress free. I did not find my self guessing at parts/bolt locations/ wires or steps taken like I find myself doing thoroughout other people's videos. On top of how easy you made this your voice is completely relaxing. You didn't speed through explanations! And I did not even one time have to rewind and rewatch to better understand anything you did! I can't say enough how awesome this video is! I will most definitely be subscribing & checking out the other videos on this channel!! Thank you for making this so easy to follow along with!!!!
Thank you heeeaps for this. I followed step by step and she kicked over on 3rd kick. It did take me a bit longer than you however, about 3 hours, with my tea and a couple of ciders in between.
very good explained video,, i am planning on doing this to my taotao 50 and also other upgrades.
I did it today came out perfect started right up
Thanks for the great video. I am having this done for me and i just wanted to see what was involved! Glad I didn't try it myself!
This was amazing! Thank you!
wish i knew you lived close bc i feel you'd do the job with perfection
Excellent video i learned quite a bit about the kit and how it works my guess is that its a heck of a improvement on power from the original set up
Thank you for posting this video it helped me out quite a bit
Awesome Awesome. Such elaborative walkthrough
Wow superb ..... everything clear
Respect for labor, thank you sir 🙏🏻
2018 gator scooter 49cc
I just installed big bore kit
I watch your video about 3 times and I did it start it right up take off the emissions everything is good thanks alot
how much faster did it go???
47 to 50 it depends on the weight and the wind
@@george102472 With scooters, weight doesn't really matter to a degree as they are designed to have the toque to carry different load... my mate is 190LB and I'm 250lb and there was zero difference on flat surfaces and hills
thank you so much for the video now i can install big bore kit on MY 50CC SCOOTER

+YJ's & XJ's All Day thanks for the comment! You are very welcome!
@@RouseGarage How reliable and do you need to replace the gasifier?
I liked your video cleared up some misconseptions
Watched a difference video of this bore kit install the whole time I was like what’s the torque spec for the head. Needless to say theirs never ran lol. Thanks for the vid man awesome job
best video on this. Thank you!!
Great info!, great video!!! 👍
Great video brother
Thank you very much for this video very helpful
looking forward to installing a big bore kit on my scooter, watching this video beforehand and it doesn’t seem that bad, thanks
Do you have a link to the kit you bought?? His link in the description doesn't work anymore
I have a 100cc big bore kit coming in this weekend and I’ll be using this video for each step. Thank you for all this detailed information.
How did it go?
@@kkaarriimm It went really smooth and it’s running great and so much quicker. Super excited about it
@@7777R thanks for your reply I’m glad it worked out for you :)
May I ask, was it possible to fit a 125cc or was it exactly for 100cc bore?
I mean like the engine itself, can it take a bigger size cylinder?
Great video. I would add to check the flywheel to make sure it's still at TDC (the "T" at the mark) before closing up the engine... It's not impossible for the flywheel to get turned/rotated while you're trying to get the rings and piston into the new cylinder. You should recheck it before lining up the camshaft and timing chain.
Best Video Thanks
Great video. Thank you!
Thanks fore shareing great information! ✨❤️
Great job
great video!
Thank you Awesome Video!
Great video just order the big bore kit
Nice video, thanks. Your garage looks like mine, accept I have two 65 Mustangs.
Awesome 👏 bravo!!
I followed your video and installed a big bore kit, high performance large valve head and a A9 performance cam. Thank You! Yours was the best I've seen to do this.
I'm going to put a big bore kit in my wife's scooter as well. On your video everything was stock except for the big bore kit. My question is do you think the larger valve head and big bore kit are worth it or does it add very little performance in relation to the added cost. I ask because you didn't bother with those upgrades. Also want your opinion of performance exhaust and heavier/ lighter rollers as far as actual performance high end or otherwise.
Great video tutorial
Videos like this save me money… I don’t have to ask the local shop In spfd, mo lol
Great video!:)
Very good video men...
Great video...I have the same taotao scooter....will be doing the same upgrade..... wish you had shined more light, on what you were doing; but none the less, great/informative video......
