Definitely do a 49/17 gear up kit! This opens up your range that you cvt works with. Add red contra spring and red clutch springs with the stickiest clutch you can find and the lightest clutch bell you can find. 5 gram Dr pulley sliders. 89mm variator. 24mm carb and intake manifold from 150cc. Stock pilot jet from stock carb. 125 main jet. 52mm bbk. 52mm head with oversized valves. CR7HIX spark plug. Orange coil. Blue Cdi. I see you already have the exhaust and air filter. This setup has me going 59mph so far. Beats my 150 off the line. My 150 quantum only has a higher top speed. My 150 can’t catch this build otherwise.
@BackWheelBenji I weigh 190 lbs/ 86kg and the scooter comfortably gets up to 55 without tucking. My son and I tried 7 gram Dr pulley sliders with this same setup. We lost 8 mph top speed for not being in the engines power band. We tried the 7’s as we were both concerned about the rpm’s being too high. With not having a tachometer, wanted to preserve the motor. We since put the 5 gram sliders back in and are running the scooter a bit richer to keep temps down.
@BackWheelBenji we bought a Kevlar belt which is a lot more slip resistant. Great for acceleration, top speed, and longevity. Bad for keeping the same size weights. A good problem to have. We bought 3 gram sliders that respond the same way with the Kevlar belt as the 5 gram sliders responded with the crap stock Chinese belt. Installed a 28mm Nibbi carb and a 130 main jet. Still keeping the stock pilot jet. This thing screams hard loud and fast! Still need to test top speed with only myself on the scooter. Made it to 48 with myself and my daughter on the scooter while she operated it. Total weight 310 pounds. I’m pretty sure I had it going faster. I can’t wait to see how fast I can get it to alone!
@BackWheelBenji 49/17 are a taller gear and better for top speed. If you take 49 divided by 17 you get 2.88. as for 51/17 you get 3 .
Did you get a different crankshaft?
Curious what size intake and exhaust it takes.
Just got mines dond today and its amazingg!! I can almost do a wheelie 🔥🔥🔥 , the torque😳😳🥵 its amazing!!!
Just got mines today if I could describe it it feels stronger definitely more responsive I love it, everything else is OEM
My dad and I put a 110cc kit on a Chinese moped and it lasted 4 years of constant beatings, and it topped out at 53mph. Unfortunately we spun the rod bearing last year
If you rebuild them and jet them right they’ll last forever. You just gotta change the oil frequently. I have a 72cc kit and fully built transmission and i beat on it hard daily. Runs like a champ.
I’ve done a bbk along with every performance upgrade I could find online. Carb with upgraded jets. CDI, Cam, exhaust and air filter, Etc. I was able to get my scooter with 13” rims to go over 60mph. Did the same thing on a scooter with 10” rims and it tops out at around 45-50mph.
13” rims in the front?
reliability and gas mileage.....pshhhhh.....its time to lower that thing, some sick nasty paint job, some wild musical horn, and a bosozoku style exhaust lmao!!! Oh, and a sound system is a must of course.
I know the cold is coming, but I love the content! Lets keep that mod list going till it gets here!
I’ve been watching for a bit you guys rock thank you
Thak you! we appreciate your kind words
Thank you for creating such an informative and entertaining video. Your hard work and dedication to the topic really shines through and I appreciate the effort you put into it. Keep up the great content!
Thank you! I appreciate that a lot. Glad you enjoyed it
I really think people getting life cut on their engines is due to them doing a crap job taking care of it. I would love to see you do a budget wideband.
We were looking at the rolling wrench wideband kit. A budget set up would be interesting tho! Maybe Amazon has some goods for a budget setup... gonna look
Regular maintenance definitely goes a long way but a 50cc piston is about the circumference of a quarter. You’re not getting much power out of that
It’s exactly 39mm. The BBK is 47mm
@@brazwewn see. Big difference
I got one for 80$ and put it together in like 2 hours and it did over 4,000 miles and is still running
That's good to hear!
I bought a tao tao 50 used I put a carb on and upgraded ignition removed restrictor ring and it takes my 300lbs ass to 30-35. Top end is a little slow
Awesome bro,I just got into the hobby,it's a headache but fun
Haha you described it perfectly 🤘
I agree with you Big bore kit I have no problems at all I've got so much low-end power to get me out of trouble anybody that disagrees with it you need your head examined it's not like you're buying a $50,000 car
The one thing I hear about the big bore kits is that they shorten the life of your engine but never find any photos or videos of such failures caused by them. I'd say the life of the stock 49cc engine will be shorted just as much if not more considering how hard you have to run it just to get to 30 MPH if it'll even do that while stock.
It's still running strong! Time will tell but I think it was absolutely worth it
@@throttle_therapy Good to know. Thinking about installing one into one of the two scooters I got for free about two weeks ago. Got one of them road worthy again but the other needs a little more work. The previous owners did a number to the body panels and wires but I manage to get it to fire up and idle a little bit yesterday. Might put a big bore kit on that one while I try to restore it or sell it to a guy who's been begging for me to sell it to him as is.
@dekoldrick heck yeah!
The 50cc engine is plenty fast imo. Go around me if not I couldn’t even care 😂😂😂 SCOOTLIFE BABY!
Do a oil change at about 200miles lets the bits of running in metal out.
if the drivebelt is old,It could give you al liiiittle higher topspeed.With a new belt.
Folks use the stock air box tube, then bolt a $5 carbon fiber cone, next a nice ex for $45, both from Temu
Honestly, the gas mileage was something that I was wondering about, cause i'm considering a bbk. but like, if nothing else it seems like your scooter may be running better than it was (speed wise not included)?
As far as dumping money into it, like...my scooter has almost 6k miles on it already. I figure at worst if i blow the engine in it, i can shell out $350 and just get a new engine that's already a 150cc, and have a friend weld new mounts on. frame and plastics are still really good on it, why not keep it going?
Exactly our thought process on this! Really excited to try a wide band at some point to really dial in the carb
@@throttle_therapy man, i would love to get a wideband...i'd also love to be able to afford something like that which i'd probably use once? maybe twice? lol
i have a 50cc liberty 4t, i was wondering if its worth it to invest 300 euros worth of equipment to make it better, a 80cc bore kit, carburetor, exhaust system etc...
Get the monster kit from rolling wrench it's worth it to me
Would be cool to try it for sure!
Question for you if it snows there could you a fix a track instead of a wheel
We actually built something with a track in another set of videos! We called it the skank. Check it out if you have some time!
@@throttle_therapy ok will do thanks for the reply
Can I put 80 cc engine from a mini bike in one of these scooters it’s a pull start 80cc monster moto
what RPM are you turning? I wonder if you would benefit from taller gears...
how big is your carburator?
I've got a gy6 (08 Lance Charming) and have been thinking about putting a big bore kit on.
have you been tracking fuel usage? I use an app called Fuelio for all my vehicles.
what is a wide band gage?
Wide band monitors air fuel ratio to get tuning correct
@@ArlenTattoo thank you!
What exhaust were you running in this video ?
I’m curious about the quality of the parts from Amazon. Does anyone have a reliable place to get good quality parts for a job like this ?
Rolling wrench, or scooter swap shop.
@@throttle_therapy thanks. Amazon is definitely not a motorcycle dealer and they’re going to get parts from the cheapest place they can find.
Hey what about power as in torque or hill climbing with ease? can you feel the difference?
please respond
It made a difference in hill climbing. It still slows down but not nearly as much as before.
@@throttle_therapy cOOL THANKS mate
Did you have to get a motorcycle license or have one already to install the 80cc kit? I have a Kymco Agility 50 and have upgraded everything except a bore kit. Still not much change in top speed so far. Need to keep up with traffic. I live in Florida. Maybe it's time to get my endorsement before I upgrade CC's.
You ride a 50cc block and just BBK it
Hey! What jet size are you using?
Me and my son both have a 50 cc and we are allways racing around together so I was like what else can we do so I seen the big bore kits and said Im grabbing two kits and put them on our bikes and after I bought them I noticed they don't come with cams,damn so I'm trying to search and see if I can use stock or is the lobs different
I think you can use the stock cam. But a lot of people recommend the a9 cam
I’m getting 40-43mph (flat smooth surface, no wind resistance). How much more top end should I expect with an 80cc?
Yo tengo una 80 cc y lo que alcanzo son unos 37 mph pero es pesada
can I use my stock cam??
my kit dosent come with a good cam
yes you can, but its not recommended.
throw a final drive in it lol last thing to add. should get 50+
BRO 45 MINE GOES LIKE THAT NO KIT 😂😂
How so?
Can u use the stock cam when doing the big bore
Yes the a9 cams are not much better..but there like 12$ on amazon
yes you can, but its not recommended.
i need someone that can help me with my scooter because i cant find any videos on it
What's the problem?
My friend owns a scooter store I tattoo him (I am a artist) he told me the kits are cheap quality and it’s a waste 🤷♂️
No it’s not it all depends on what you get now you’re talking about a Chinese quality parts yeah they’re cheap and low quality now if you’re talking about Taiwanese or Japanese that’s different good Taiwanese makes parts for Japanese bikes in Mike’s bikes for Japanese people Bikes I had an 80 Chinese kite just bought it so I can get the muffler now anyways those Chinese kids are cheap the only thing that is quality is the muffler and that’s about it when you’re talking about Taiwanese stuff like the engine you’re speeding $200 nearly 300 I spent 240 on my Taiwanese engine that should tell you something that is high-quality you get what you pay for what you’re talking about a Chinese kid you’re spinning about a hunter just for not just the engine but the muffler in pretty much 60 or 80% of the full replacement of that engine that should tell you that nearly every part that you’re getting a little quality
Ensure enough ain’t going to last long I had to swap out all that shiny stuff because I have a Taiwanese engine and probably the reason why my bike was misfiring and not starting is because of it so I swapped everything to Taiwanese in I bought me a premium American spark plug in on top of that I’m replacing these old stater to a current one that they make a noww Every five years of 10 years they improve the quality of Chinese parts so that you improve the longevity of my bike
You should follow me on my channel I basically swapped out all that cheap Chinese parts out of my bike and put nothing but better quality Chinese parts in it in Taiwanese but when it came to the engine I put nothing but higher quality because it’s an engine the only thing that I kept in my engine that Chinese is the bushings because that’s not directly in the engine or making the engine go it’s just bushings to protect the engine Mount from the bike hitting it and they say the Chinese bushings are better than Taiwanese anyways With the quality
Nitrous kit lol
I'd like to buy a scooter specifically to do that to!
@@throttle_therapy well i have one with no title here in oshkosh Wisconsin was abandoned by a former roommate and it was registered to him.
