The chinese speedometer is actually 5MPH overrated across the board. I measured the green speeds with a GPS. The orange speeds are deducted from the green speeds The red speeds that I added are approximations deducted from the orange ones, and may be off.  As you can see the MPG speed rating on the speedometer pretty much is 5MPH overrated across the board. 40MPH is when the needle is straight up (actually 41MPH, but who cares...) |

Synthetic oil IS "dyno" oil all they do is order the molecules the way they want them but, all motor oil comes out of the ground. Some just gets a higher level of processing. So that being said it is all compatible. Also I haven't seen any evidence that at least in a air cooled GY6 that it has any advantage worth the extra cost of your run of the mill motorcycle oil... Semi synthetic oil is dino oil. Fully synthetic oil is a much different process. They don't refine dino oil, they build up the molecules from the ground up using gasses (like ethylene or propylene and other stuff..). |

I just came from the interstate to Ft lauterdale guys (from miami, a 2x 33mile tour), and you won't believe what I have to say!
Agv top speed is 60MPH, for sure; but when the engine is running for a while, and is hot, the top speed goes up to 65. With a back wind, or someone cutting through the wind in front of me, it goes almost 70MPH (that's on the speedo).
Not had a single problem going on the highway.
What's even more amazing, is that I've got a 110MPG out of it!
I was largely racing on the highway, and perhaps the fuel tank wasn't topped off (so that number could drop to 106 or 105MPG real calculation).
But I could not believe I got better MPG out of it than my ATM50!
haven't measured it, but I believe 70MPH on the speedo, should equal ~60MPH GPS.
That being said, I still would not recommend the 34T sprocket upgrade, but the 36T upgrade; as the top speed is susceptible to winds, and rider's weight and riding position (70MPH is attainable riding while laying flat forward on the handlebars).
I'm gonna have more accurate highway MPG results soon, when I do a fuelup. I mainly rode WOT for about 1 hour to and back.
I personally prefer to use the choke to adjust the mixture.
The problem with a choke is that you can make the mixture richer, but you can't make it run leaner.
If your bike runs best with choke off, chances are with a weather change, that you might be running rich, and no way to lean out the mixture for perfect combustion.
With the choke, I can create a perfect ratio, however, at the cost of having slightly less top end power (unless your A/F balance is way off).

Oil is oil. regular dino oil has <2% millennium old cockroach shell in it, semi-synthetic <0.5%, and fully synthetic 0%.
By replacing dino with fully synthetic you have less than 0.1% impurities from previous oil.

Well, it's partly not their fault. Your payment didn't come through, and they sold their last scooter of that type before your payment was cleared.
You'll most likely have to wait for the scoot to arrive from China.
You could always look around for a better deal, see if perhaps you can add some money for a better scoot (since you need to wait anyway, and an additional pay check may help out to get you a better deal on a better scooter).
They're slow on internet and mail replies.
Best thing is to call their number directly from the site.
I know, when I'm in FLorida time, they only pick up the phone between 10 and 11AM.
So I try to call them around that time. In the afternoon they're closed, and in the morning (like 9AM) the waiting lines are too long.

Alright guys, more data came in! I gave Rebelgears the dimensions, and they will soon add this motorcycle sprocket to their arsenal, thanks to the dimensions I provided them. Here's my data on the sprockets: - Mechanically a 30T to 46T should fit the bike - Preferably you will not want to go below 35T, nor above 38T, as that is your sweet spot. 36T is the optimal sprocket; which I would suggest you, for a single rider ~170LBS; because: 1- The sprocket can be installed without having to cut, and re-attach the chain 2- You can reach the bike's top speed with this sprocket 3- You still have good acceleration in 4th gear, while gearshifts from a standstill feel A LOT nicer!!!! 4- Cornering in 4th gear (~20MPH) is possible, so no downshifts necessary. For the 34T sprocket: 34T top speed equals 40T top speed (~60MPH on dash, both in 3rd and 4th gear with the 34T). Because I care more about MPGs, and I installed the 34T, and had to shorten the chain, and will not be installing the 36T. If you weigh more than 200LBS, and ride in hilly terrain, I might suggest going to Rebel Gears, and get a 37T or 38T. Prices are ~$60 tax incl. I am willing to sell my stock sprocket, as well as my 36T, for $30 each, $50 for both; shipped to anywhere in USA. PM me if you're interested. Again, if you're more than 200LBS, or ride with 2, or ride on hilly terrain, I would not recommend the 36T but a larger one. The motorcycle, stock with ~10W40 does ~  .5MPG ~10W30 does ~86.5MPG So in other words, expect it to do 85MPG stock. With the 34T after calculations, I should get  -100MPG With the 36T you should be able to get  -95MPG. My experience with the 34T sprocket: Easy to install, however linking the chain back together without proper tools is difficult. Make sure you grease the rear wheel axis rod, and the chain, and adjust the rear brake, as well as correctly tension the chain! Using the 34T, I noticed a significant reduction in vibration, a much smoother ride, MUCH better (longer) gear shifts; rides almost like a big bike, with the exception of final gear low acceleration, but it's easy to downshift to 3rd gear for better acceleration! Shifting to 4th gear with 34T happens at ~30MPH on the speedo; cornering at 20MPH in 4th gear is difficult. Engine goes into low RPM, and U-turns is necessary to downshift. With a 36T it might be possible to do U-turns and corners in 4th gear. Also, 10W30 oil is NOT recommended for hot FL. I've noticed that the clutch occasionally slips. 10W40 IS the recommended oil for this bike, like the usermanual says. 10W40 is a bit on the thick side for the engine, but is about the thinnest I'd equip the clutch with. If you live in colder regions with weather below 80 degrees, 10W30 might work better for you, but in S-Florida's  + degrees weather, 10W40 is recommended |

Did you ever get it to run without the choke partially on? It runs (when engine is warm), but bogs when opening the throttle. When rolling open the throttle, with the AF screw set correctly, I notice that it idles fine; about mid-throttle the choke needs to be opened the most (air cut, most fuel added to the ratio); but when the throttle is opened wide, the choke will close to 1/4 for best performance. This leads me to believe that the idle jet is WAAAAY too small (running way too lean), and that the main jet is less lean as the idle jet, but still too small (lean). |

Well, for the $799 they're selling them for, they're a steal, especially if you can pick em up from Calif warehouse. Add the $2xx shipping and it's less of a nice deal, but still wonderful.
Add a sprocket change, and it will work really well.
The 34T and 36T are on their way.
If the 34T works, and I still have clearance, I'll get a 32T sprocket, or perhaps a 30T; just have to see how the engine is keeping up with the heavier gear first.
For sure, the 36T sprocket will be some improvement from the stock gear.

Yeah, there's nothing like displacement;
On average you'll need at least 400cc's to cruise 50MPH @ 3k RPM; with 500cc's you can cruise 60MPH, @~3k RPM. But with a 150, you'll probably go 45-50 tops.

CBR's and especially Ninja's are what's called 'short stroke' engines.
Their cylinders don't move up and down as much, allowing higher torque values at higher RPM's,
With long stroke engines (which are your stock engines), torque curve is hill curved instead of an up-slope, and the gas mileage is much better (more optimized), as with short stroke engines much more of the released energy goes to the exhaust.
Anyway, in many cases you can get over 10-12k miles out of a 50cc engine, and 15-20k miles out of a chinese 150.
I'm also sure that even before you reach that number, you will find that the scoot has paid itself back multiple times.

yeah, but the ATM beats most 4t 50cc scoots hands down in top speed, and at least some in acceleration. True, it can't beat a 2t, but it could keep up in traffic somewhat.
And 3k miles takes quite some time if your avg speed is from city riding...
Sometimes I'm limited to my riding speed, meaning, if I have a whole afternoon to ride, at 40MPH, I can probably cover a good 100-120 miles on my 50cc.
On my 150cc, I probably go on the highway, with top speeds of 60MPH, so I'd arrive at my destination sooner, and decide to keep on riding, so I might end up with a good 200 miles ride.
On my motorcycle, I'll probably take the highway, or interstate, and do a nice 250-300 miles on an afternoon
So what I'm saying is, that for a motorcycle, 3k miles can be done within a few weeks to months. On a 50cc it takes me ~6months to a year to get that.

Well, 52MPH can be done at 6k RPM. But if you want to lower it to 3k rpm, you'll probably only go 40-45MPH tops. Engine won't have much power reserve left to accelerate.

Tao's are great scoots!
3000 problemless miles, in the elements (pouring rains, blazing sun). Only thing is the blinker switch gave out, I have to check the electronics.
Those ATM50's are VERY good, simply because they have such a low maintenance, because they have so few parts.
I would have only chosen the Stella because it's 2T, if it was 4T I would have gone with the TaoTao ATM50.
On top of that, the ATM is easy to maintain. Almost everything is accessible without removing the body panels (just the seat bucket).
They say less is better, but this is especially true for chinese bikes!
Less means less parts to break down.
