I've started with synthetic, and never had problems. The thing runs stock now at almost 3000 miles with zero issues, and superior performance!

I believe it depends on were you're living.
If you're living in colder places like alaska, or canada or something, 5W30 might be a good all year round oil for that scoot (save for the summer).
i personally am still looking for the perfect mixture, but so far the best I got in hot S-Florida is 12W35 (a mix of 10W30, and 15W40)

I'm still waiting on parts on mine.
I got a 29" beach cruiser, and installed a 32T sprocket, instead of the stock 41T sprocket.
Theoretically it should give me a top speed of 41-45MPH, which I'll never go that fast; and a gas mileage of ~120-150MPG tops.
I haven't taken it out for a spin yet, and it is a 2 stroke though.

The T3 is inherently not that much different from the ATM50. If you want to go faster, you could put a mix of 10W30 and 15W40 engine oil in there; if you don't like mixing, use 10W40; 10W30 might work too, but it does wear out the engine a bit more. Also run the scooter on BP Premium fuel. Costs you only a few ct more per gas tank, but the performance is at least 10-15% higher, sometimes even upto 20% higher. Pump up the tires to 35PSI And for me personally, gapping the spark plug to 0.012" gave me best results! Aside from that, you can put a performance exhaust on it, but be sure you're running  oct fuel when you do! (BP preferably); but the increase in speed will be minimal. |

My opinion:
It means the scoot goes for 745; which includes the product and dealer fee,
On top of that you need to add taxes, and tag or tag transfer (which cost little over $200 to do).

Sounds about right.
My 150cc goes to 5000-6000 RPM (depending on the throttle)

I've done 200+ miles on a 50cc scooter in one trip.
Theoretically you could go 6-8k miles with it the least before it needs maintenance.
It does not really matter if you are going to do this in one trip (with oil changes), or in many small trips.
I personally would say that a roketa 250 is perfect for going around town, doing the 20-60 minute trips, even 20 minutes on the highway.

On my BMS260 it also depended on which fuel to take.
Regular and premium gasoline where a bit less good than mid-grade.
With mid grade, I had an average of 3MPH faster.
Regular, 79-80MPH top speed, premium ~80-81mph top speed.
And BP gasoline is of noticeable better composition than mobil or other gasoline.

Great article!  I usually don't like sarcasm, but I enjoyed it thoroughly in this one, as I can relate to the DMV personnel screaming 'NEEEEEXT' in your ears, and look at you like you're some kind of burglar or thief, and if it's just too complex, they don't know how to do it. in FL, an independent drivers license office might be able to help you out a lot better! |

There's a lot of water in gasoline now (ethanol molecules attract water vapor and mingle it within the gasoline).
That causes water damp in the pistons, which condensates in the exhaust again.
That, and together with the air humidity, is why you can see so many cars having water come out of their exhaust pipe, when they're departing from a red light.
I don't know if that water affects the catalytic converter or not, though when it exits it looks quite clear.

I never wear a helmet on my 50cc, but I'm planning on selling it.
Turns out I'm going to do a lot more of long distance riding, and will be needing the 150 more now.
On the 150cc it's crazy to ride without helmet, and even though it's not required, aside from some short trips, I always wear a helmet.
On my motorcycle too.
Today I saw an accident happen right in front of me, on an intersection.
I was thinking, lucky it where 2 trucks. One guy, just stupidly accelerates through a red light, while someone was making a turn. If that where me, I'd be flying in the air.

I tried that and it did not work its a hokes. It probably depends on : 1- if there's electricity on the wire 2- If you're standing on dry solid ground with rubber boots, or on wet moist soft soil with sneakers. I know to feel the electricity in an electric wire, and you are standing on wet moist soil; all you got to do, is take a large, wet reed of grass, and touch the wire with it. it'll give you a partial feeling of if the wire is electrified or not. You could also just grab the wire with 2 hands; and get hurt; or piss on it, or try crossing over it bare butted with your balls touching it :-) It'd probably be an interesting experience! I wonder if there will be any fireworks from that! |

BTW, they sell batteries at BMSbattery.com, if you're ever interested in experimenting with your own LiPo, or LiFePo4 batteries.

The lithium batteries are the wave of the future. But one needs to use a special charging circuit for them though. A regular battery charger won't be able to charge them properly without damaging them. The lithium polymer batteries can be dangerous as if something happens they can go bad and burst into flames on you. The more safe LiFepo4 batteries don't normally catch fire and thus would be more wise to use. You see the LiFe batteries in the hybrid and electric cars for that reason. But with a good LiPo or LiFe battery charger the batteries would have a much longer lifespan over the old lead acid batteries. One problem with lead acid batteries is that because of the lead and acid too, no one wants to make them much anymore as it is so environmentally dangerous to do so and becoming very highly regulated as well. Worse is the batteries seem to be getting worse and worse as to quality and are going bad much faster than they used to. What you're talking about are regular Li battery cells, soldered into a battery. The stator won't ever produce enough voltage to overcharge them; so you won't need to worry about them catching fire. However, most batteries come with a BMS (Battery Monitoring System). These batteries have a chip within the battery, that regulates the charging of the cells, and records their condition. When a battery cell's condition deteriorates rapidly, the BMS will disable it, to prevent current from normal working cells, to backflow into the broken cell. If this ever happened, you'd notice: 1- A drastic decrease in battery life (like all of a sudden a 10%, or upto a 25% drop in charge on a 4 cell battery) 2- A voltage decrease (4 cell batteries are the most prone to this. Voltage could go down from 14V to 10V; or even drop to 0V on a 4 cell) 8 cell batteries might still maintain a 14V load, however in the case of an 8 cell with 1 bad cell, one of the other cells will take over the power transfer of both cells; in which case it gets loaded more heavy than all the other cells; and deteriorates and depletes quicker; resulting in a 100% voltage at startup, but only after a few minutes of using the battery, without a charger, the voltage could drastically drop to 75% (aka 10v, on a 4 cell), and from there depletes lower at it's expected rate. The best batteries are those with all cells soldered in parallel, and a BMS that electronically ups the voltage to the needed 12V. There are very few of these out, and they cost quite a bit. Most of these batteries are soldered in series of 4 batteries, to get the 12V (14V) needed to run in scooters. Then depending on the amount of cells they create 1 or 2 or more strings (eg: a 4 cell has 1 string of 4 batteries in series; an 8cell has 2 strings in parallel with each 4 batteries in series, etc...). |

a higher cranking battery isn't need in a stock scoot, the 7ah regular battery even cranks the cheapie ebay bbk's, its when you have a 52mm or a higher quality bbk with more compression, something is needed if the lithium can crank over my 52mm kits i'd be a happier guy, so more than likely i'm gonna have to go this route, i'll post after i get one, already posted the before vid Too high CCA's could easily burn out your starter. The battery's voltage drop is very little, causing the starter to rotate faster than with a normal battery. Under normal circumstances, this would be a good thing, as the engine would crank faster; however in the case of a dry vacuum fuel line, where you'd have to start for several seconds, to tens of seconds, it's easy to overheat the starter. The chinese user manual, with current 7A batteries, already says not to crank the starter too long; and give it long pauses in between. (like 5 seconds starting, and 20 seconds break or something, before cranking again). |

oct fuel when you do! (BP preferably); but the increase in speed will be minimal.
