Top speed is gained by running the engine warm. The first 500km you're not supposed to hit it, as you're breaking in the engine.
After about 500km the engine starts going better, and the engine performs better when it's hot (after 5-10 minutes riding at WOT, or 10-15minutes riding normally).
It also performs better with BP Premium fuel, like most other scoots do.

+1 cheap fuel will do just fine. The chinese always overrate their crap, thus  oct fuel equals 87oct fuel in USA. See [[Octane_rating]] |

In Florida there are only three classifications of 2 wheel motor vehicles. Motorcycles, mopeds and scooters. what most here ride and call scooters are considered motorcycles in Florida. Any powered bike that has a seat and can go over 30 mph is considered a motorcycle in Florida. According to the DMV in Florida the posted rules are: "Two-Wheeled Vehicles Defined If you’re unsure about the registration and insurance requirements for your two-wheeled vehicle, please call the DHSMV at (850) 617-2000 for clarification. Motorcycle¯Motorcycles are generally the easiest of the two-wheeled vehicles to spot. Know that if your two-wheeled vehicle has an engine displacement of more than 50 cc, Florida considers it a motorcycle and you must register it. Mopeds¯Your vehicle is a moped if it has: Three or fewer wheels A seat Pedals that allow you to propel the vehicle A motor of two-brake horsepower or less The ability to go no faster than 30 mph An Automatic power-drive system A displacement of 50 cc or less (if it has an internal combustion engine) Scooters¯Your vehicle is a scooter if it has: No seat or saddle Three or fewer wheels The ability to go no faster than 30 mph" Not quite so, I've looked heavily into these things when I first try to find how to register my electric moped. Turns out FL is 10MPH higher than most other states, meaning, In FL, a moped is limited to 30MPH, and a 49cc scooter to 40mph. and the displacement is 49cc or less, not 50cc or less. |

yeah, the vid is of the original tomahawk from chrysler, with 500HP engine
The one I posted is a chinese clone, with a stock 150cc GY6 engine (limited to something like 10 or 11 BHP?)

Sustained 55mph... Is that stock? Yeah, that's pretty much stock! The TaoTao's that are made after 2012 are pretty well tuned from the factory. Very little room for improvement on them. Quite often putting performance parts on them actually degrades performance, unless you're putting a BBK. I've never had to do a valve adjustment on the EVO150, but a mechanic I know said he had an ATM-150 in the shop with 3k miles on it, with burned valve ends or something. It's only $80 + workhours, but make sure you do a valve adjustment before you hit the road, if the bike is made before 2012. |

Looks almost identical to the EVO150 inside too.
Just make sure you mount that horn, before mounting those plating. I got mine stuck inbetween the front fork and the frame, causing me not to be able to turn (I overlooked to mount it)
The EVO150 does 63MPH tops, but a sustained 55MPH is possible. BP Premium fuel gives a tad more performance, and on that, it tops out at 60MPH sustained.
I think the ATM-150 should be similar.
The PX150 is a bit slimmer, less body plastic, less weight; but would have benefited you by being more aerodynamic. Top speed on that one is estimated to be <65MPH.

I'm surprised my ATM50 still runs awesome, after 5,5k km, without valve adjustment. Idles fine, runs great....

Sounds about right. I get 115MPG with my 15/31T sprocket setup and 127cc engine. On my bike I could not change the front sprocket, because I haven't yet found a fitting 16T (that uses the 6-grooves/ribs on the axis, instead of the multi groove systems).
These types of engines have their best torque around 6.5k RPM, so it makes no sense to even use of those last 2k RPM, as you may see that reducing a rear sprocket, or increasing a front sprocket will still result in the same top speed.
I went down 10 tooth on my rear sprocket, and my top speed is still the same, but I'm suffering a bit 'cause of lack of torque.
It makes most sense to change the front sprocket, upping one or two teeth; because front sprockets are cheaper, easier to replace or install, and don't require chain shortening.
But in case that you can't change the front sprocket, changing the rear is just as good.
When stock you have a 15/41T, and you'd change it to a 16/41T, it would be about the same gear ratio as going to a 15/38T setup, but like cat0020 mentioned, it makes more sense to change the front sprocket when you can, than changing the rear (front sprockets go for ~$20-30 shipping included, rear sprockets go for ~$50-65).

AYFKM? (Are You Freaking Kidding Me)? LOL Not a price for a chinese bike. If the touring bike was 400cc, they could sell them for $4k, for 650cc $4,5k, $5k would be tops I'm willing to pay for a chinese bike.. |

I think oil is a good thing for the air filter. If the air filter is a sponge-type of filter, oil on it is a good thing to keep it moist and filtering better... I wouldn't know how to rout it to the airfilter though....

CF Moto getting 2 x 650cc motorcycles, 2 cylinder parallel engine, 8 valves. naked version:  and same bike with touring body:  I wonder how much they will cost! They certainly look good, though the impression I have of the touring bike it's that it's a bike made not for tall people, 5'5"-6'0" I think the 650cc is a big step up from the chinese's 250cc engines; and personally see no reason to make these bikes so high in cc's. but rather equip them with 300-400cc engines would be more than enough. But the good is that the chinese are finally stepping away from the thumper models, and V-twins (mainly lifan makes them), and getting a parallel twin. Those engines are usually better for racing, as they perform better in the higher revs.. Small, efficient, cheap to manufacture, parallel twin is the future of chinese engines. If they only made a parallel engine with 2x25cc, it would beat a 2 stroke 50cc engine hands down! |

in FL it's mandatory to have a MC license for anything above 49cc. That includes a 50cc with BBK, however most cops won't crack down on BBK bikes, if they don't go over the legal speed limit of 40MPH, or the road speed limit.
In reality, most 50cc scoots around here go 45MPH tops.
MC endorsement costs $225 if you go in weekdays, or $275 in weekends, and is worth every penny! I think it should be mandatory for everyone riding >50cc scooters or motorcycles.
We have a different law here for mopeds. A moped and a 49cc scooter fall under different categories in FL.
A moped = needs to have pedals, or working mounting points for pedals.
Needs to go <30MPH, (20 MPH in most other states)
Needs to have <2BHP, or 1BHP (750W) when powered by an electric motor, or <25cc two stroke engine.
A scooter = 40MPH top speed, <49cc, or <3BHP.
A 2 stroke 49cc usually does not fall in that category, as it has >3BHP.
On the highways in FL the minimum posted speed is 40MPH, top speed ranges from 55MPH to 60MPH, and interstates top speed = 65MPH. (but cars go as fast as 80MPH).
The minimum needed to go on these roads >5BHP, or >75cc. In reality, you need >125cc to go on the interstate, or highway, but preferably >200cc for the interstate, and >150cc for the highway to maintain speed (highway riding usually is 60-65MPH, interstate usually 60-80MPH, except for traffic jam).

The EVO150 is the successor of the ATM150; second version if you will, and looks nearly identical!
I guess you don't like the PX150; but the EVO150 = ATM150 in looks (minus some minor differences).

Yeah, I also ride to explore the neighborhood, to discover new roads, to know which stores are where.
Not always am I looking for beautiful nature spots, but sometimes I'm looking to see where I can find what store or mall.
