I hope you guys found this video helpful on replacing the engine sprocket to gain a little bit of top speed. Link to part: www.amazon.com/dp/B07MXYG9B7?...
My son has the same bike but he rides it on the road all the time and the nubs are worn down on the tires what kind or size street tires can I put on there?
Sacrificing torque for speed is great in level areas but for long hill climbs you'll end up down shifting and slower than you were with the smaller gear.
15t to 17t on a 125 pit bike basically stays the same. Mine felt similar in torque and gearing was longer. I would only suggest to go 15 to 17t and nothing more on front or back sprocket unless u just want speed.
I wonder if there's a 19 tooth out there gonna bang on a bigger carburettor already got the carbon fibre metal mesh intake I run my bike on Castrol Syntec gold I find it quite good keeps the engine running smooth plus added fresh new bright green fuel line can't wait to finish my custom stomp these vids come in handy when Im looking to get that edge
Should have got a nickel plated or gold chain while you're doing that change up but they do have spray rust proof gloss for your whole bike uv protection Amazon
Worked on a similar frame rfz 125 elstra nitro circus addition pulled it all part sanded it done it chrome and slappee a 160 in it sold for 1200second hand
Oh the irony of making how to videos when you dont really know. You installed the wrong size sprocket. You have 428 chains, and managed to order and install a 420 front sprocket. You are asking for trouble, that chain will slip sooner or later specially under heavy load or top speed.
I have an Apollo Rfz 125 and I did this mod and the old chain worked. It was a tight fit and very frustrating but you can make it work its just hard to get on
iNoSkilz _ thanks bro I was thinking of ordering it just in case but I would think it would be the same I did it my raptor 700 and the chain work but I seen videos when they do it on the pit bike they change the chain but it should hope haha
If you replace the carb wit Amazon or eBay carb you had better know how to tune and change needle positions it took me all day to tune mine but it has a shit load more power now.

My ttr110 has a 14 and a 35 but I’m getting a 15 for more top. You went two teeth at a time on the front which is a big jump, and I thought I was jumping. Try one gear at a time to really tell
Have you tried rejetting ? My 125 does 60 with17-34 sprocket,a race cdi aswell. I'm certain that if I ran a 35 with a big wheel set it would hit 65. I'm currently running a pair of 12 inch mag wheels cos I can't be dealing with tubes.
You are most certainly right my friend tbh do you reslly need that much speed on a pit bike ? I race mine but im only learning as I never had the opportunity as a child bur ice hsd 160s and the best and fasted bike i built was a gpx125 just as fast as the 160s/1900s but the thing is I couldn't even handle this bike and it was a tiny pit bike full setup for MX pit bike racing and jumping it seems to be too much power for me now I've just purchased a kayo 125 I haven't looked at the front and rear ratio yet but I'm assuming normal size and a normal knockoff Mikuni carby which I will replace but literally I'm flat out in 4th gear non-stop but it is definitely a better bike for racing and jumping and it has a lot less power nowhere near as much power as the 160s/ gpx125 but yeah the speed going at probably max 80kms hits the jumps perfect.
@@jamesthebond0072 ide think youde need speed but ide also like my torque. I think the solution is just a bigger motor but something like this would do fine for my riding style. I have a 70 Pantera (I'm 14 so don't think I'm a fully grown man riding a pit bike😂) and I'm gonna buy a tao tao 140.

Yeah i just experienced that. I just replaced a rear sprocket and it’s already worn down. Not even 3 weeks😂 but now I’m looking to get higher speed so I’m doing research
Yeah but sprockets are always a lost for a win In this case Less acceleration but more top speed Since i ride a lot of trails enduro and track i need that low end torque

You look like a bigger kid than average and you didnt really put your head down and get aero whenever you opened it up on these tests.... air resistance is exponential as you increase to much higher speed so it takes alot more power to go from 55-60 mph than it does from 50-55 mph for example, and so on as you keep reaching even higher speeds, .... i bet if you keep your knees pressed to the gas tank and your arms in and head down so your eyes can look just enough to see over the bars and i bet you will top 60 mph easy there now with that 17t cog ... with almost any bike i ride on the highway i gain about 3-5 mph by just tucking down and i do not even move the throttle... and i generally use my chest as air brakes to help me slow down when i sit up too.. but Yes if you had sat the same way doing the 15t and 17t runs then that was good way just to compare the exact differences in your bikes performance during the tests...
No do not get a $30 carb get the NIBBI carburetor 26mm. I got one for my DBX1 and it is the biggest performance mod you can do. It basically is a racing carb and the build quality is night and day and the throttle response is insane. It does cost a little over $100 bucs but it is worth it. No one who has bought these carburetors has complained they are legit for performance gain. In first gear if you give 1/4 to a 3rd of throttle the front tire will lift off the ground. I like this mod as well however I thought you should have held the throttle open longer and you could have squeezed out 2 more MPH's.
@@Micscience what else should I do? I want to get better carb whatever you s best for torque and hill climbing I’m not racing Im just hitting trails I haven’t even hit 3rd gear yet cuz I don’t ride on straight shots
@@seanf6968 A simple way to add torque would be to install a muffler pipe which gives back pressure. That helps the low end. V2 Racing head at Tbolt USA will increase your power by 40% and a big bore kit will give you another boost of HP.

How did you hook up that headlight??
How much you charge me to do my tao tao 140 2021 like yours with light and everything
I feel like my chain doesn’t fit on the new sprocket? You didn’t have this issue? Seems like the chain is too close together

Are the supposed to have a slight bit of play the front sprocket?
A tiny bit depending on the quality of the shaft but as long as it's tight you'll be good

Where do you get sprockets at, I need front and rear and chain.
Amazon best place so far
If i buy a 428 17t sprocket, do i have to change the chain also?
What size is the rear sprocket
35t
How’d you get the light on it ?
he has a video on his channel
Might lose a little bit of quickness but you will gain top speed
Do you lose a lot of torque with this mod
A little bit
You don’t even gain speed in the long run it just makes the launch faster

Your chain will slip 428p to 420p every time you go to wheelie you will hear it 👍🏿
I noticed the error right away. I mean 428 to 420, there is a difference. Its dangerous to mix and match them.
