Paid $1,077 for my Chinese 150 scoot. $240 0f that was for shipping. There must be some type of "snob" in that!  I know, you're the shipping snob - type! Some people just wanna pay more on shipping to be cool, and I think you're just that person! I was lucky enough to pay $239 on shipping, so I fall out of the boat of the shipping snobs!  |

BS ! Bull Shazz!
No way you're going to tell me that the original engine of what looks to be like a 50cc gets any more than 21k Miles!
Besides, a china bike with 214k miles on does not look new like that bike does!
When you click on the photo it says 214 miles, not 214,000.
lol
It's a farce!

I would agree with PCB_GY6'n.
The TaoTao's pretty much come tuned out of the factory.
The only 2 things you can do to squeeze out more power is make sure the tires are at least 38PSI hard, and fuel up with BP Premium fuel.
You could also change the rollers/sliders to fit your riding pattern (eg: if you're an easy rider, riding mostly calm and laid back, increasing the rollers/sliders weight might benefit your MPG, as it will lower RPM. If you're a sporty rider, decreasing them (to accelerate at 7k RPM instead of 4, 5, or 6k RPM) might benefit you.
Other than that, you'll need a BBK. Once you install a BBK, it would be prudent over time to adjust the rollers, change the belt, adjust clutch tension, put bigger air intake, free flow exhaust, and rejet etc...
You could just install a BBK on a stock bike, and see a 75% improvement compared to 100% improvement you get when you would install the BBK with all the optional accessories installed (like uni air filter, free flow exhaust, ....).
But really, would you want to spend another $500 to $800 on upgrades, on an $800 bike?

Everyone who does not ride a TaoTao is a snob ((o

Just digging up an old article.
I'm not too happy about the standard response of the single cylinder 250cc thumper engine.
It's operating just as expected, the same on just about all chinese motorcycles (whether they be manual geared, or CVT, burgman clone or retro style, they all get about the same acceleration and top speed.
So far, I guess my interest goes to the Ninja 300, but I really wished there where more fuel efficient 500cc bikes out there.
Suzuki starts from 650cc with their S40 thumper, which many people say rattles at high speeds (too big of a cylinder for a single cylinder bike), and their smallest sports bike is the GSXR600.
Both of them, fuel economy could be better for a motorcycle, and price is over double what I'm willing to spend for them!

Another burgman clone, Roketa is making a 250 and soon also a 500cc version of this bike: MC-18-250 and MC-18-500:  www.roketa.com/product/2610/0/59235.shtmlNo specs yet. Can I speculate they put a 2x250cc cylinders engine in it? I hope the chinese will finally get the parallel engine copied, as well as a good V-twin for racing bikes. Their 250cc single cylinder thumpers are getting quite boring upto 80MPH... |

You got to upjet a size, and then put the uni airfilter in.

I have over 3,5k miles on mine, and wonder if it matters if I would do the almost 4k miles at once, or do it over time?
I suppose doing it at once is better since there will be less parts wear due to rust over the short time the bike is used intensively.

 nice! Glad you could find a front sprocket. Where did you buy it? I estimate that your 110cc should do round about 55MPH tops. By changing the front sprocket with 2 tooth, you only increased top speed, and MPG, by 14%. On my MC-05-127 I found the sweet spot to be round about that range. If you want to be better on gas, and don't need hill climbing power, or fast acceleration, you can always do 3 tooth less on the rear sprocket. It's easier to find rear sprockets than front sprockets.

FYI, the thing does not go faster than 35MPH, and probably not faster than 30 either!

They should make more engine sizes between 50cc and 150cc!
Those 125cc bikes can be fuel savers @ nearly 100MPG!
The 35MPH limitation may be good in the city, but in the suburbs, you really need something that can go 45MPH. No roads going <40MPH, unless you want to ride from one stop sign to another in residential areas.
For that, if they would raise the 50cc to 63cc, it would give people the chance to go 45MPH (50MPH even), and be safer in suburbs, than when going 30-35MPH. Not to mention have many people aggressive because the scoot takes too long to get upto speed.
A chinese 250cc usually outputs 16-18HP; the BMS260 being different due to it's 'hydraulic valves', which puts it's output to 14,7HP; but regardless of that figure, the bike still can go 80MPH; unlike most chinese 250cc's with 16.6HP that top out at 75+ MPH (usually 78MPH)

my mikuni carburetor has a choke.
The enricher principle is about the same. Kinda like an automatic AF ratio modifier.

I'd say none of your upgrades are a necessity.
I've found the TaoTao CDI's to be working better than an aftermarket CDI, and on most scoots I have at least 2k troublefree miles on, and on some almost double that.

If you had a choke, you could tune the carb on the fly for the perfect fuel mixture! If your carb is tuned a bit too lean, you could use the choke to cut airflow a bit (richen the mixture) and find the perfect AF mixture (the bike will perform better on the perfect mixture). The benefit is that your bike will be performing optimally, with best performance and highest MPG. The cons are if your bike is too lean, you need to cut back too much on airflow with the choke, and if you're having a 250cc engine for instance, and cut back too much on running lean and on the choke, you could be getting only eg: 225cc's of fuel mixture in the cylinder, instead of the full capacity; so you'll get performance loss. But a correct AF ratio on a bike that's running only slightly lean usually outperforms an incorrect jetted bike (too lean) without choke modification (meaning without cutting back on the air). It also depends on the final drive gear, and CVT or manual, as well as average driving style (city with start-stop traffic, or country, with long roads at 35-40MPH, or highway with 60+ MPH roads. MPG is optimized when the engine RPM is as low as possible, while the speed is as high as possible. Most of the time, a ~200cc engine running at 1,5k RPM, going 35MPH is having the best MPG you can get out of a bike (even better than a 50cc at 6k RPM). I think the best overall bikes are the 200cc bikes. Power enough for the interstate (70MPH), and also power enough to pull the ride at 40MPH at the bottom of the RPM range (1500-2000 RPM). So the answer to your question is not an easy one. But just to give you some kind of an answer: The BMS TBX 260 with Fuel INjection gets 80+MPG. The Suzuki TU250x with FI gets  +MPG Most chinese 250cc carbureted bikes get 65-75+MPG. |
