maybe the $300 engine fits a honda? ;D
I'm thinking and thinking, and meditating and asking questions, and perhaps I'll just replace the carb. But first I'd test to see if replacing the CDI would do something to my scoot or not.
Just one question concerning the CDI. Can one put 2 CDI's together in parallel?

you are speaking in terms of failure on the road correct?
i carry a spare. I had to change over on a ride once like a race car. saved me.
as for performance a cdi alone will do nothing.

Forgive me, but I'm not very mechanically inclined. To me it seems obvious that the installation of a fuel pump is a lot easier, than opening a carburator. a fuel pump will do absolutely nothing in this situation. the problem is not in fuel delivery TO the carb, the problem is not enough being sprayed into the engine from the itty bitty main jet INSIDE the carb. you can switch from a garden hose to a fire hose to fill up a bucket of water but if you only have a drain the size of a drinking straw all you are doing is filling the bucket faster...the volume of flow OUT stays the same. |

I know, however, you can fill up a tank faster if the water is under high pressure, then under free flow pressure.

Sure but what good does that do in this situation?
gravity keeps plenty of gas in the float bowl. the jet that sprays gas into the combustion chamber is too small, that is the problem sir.

opening the plastic casing of a scooter scares the heck out of me! plastic? you take the seat bucket out to get to the engine, no bodywork removal required. |

I just purchased a 2012 49cc TaoTao today. It has a MMG 70cc Piston/Cylinder kit installed and the rest is stock. It barries the speedometer over 55mph. It runs super smooth as of now and I really like it. My question is should I be concerned with the stock carb as this thread warns now that there is a new piston and rings (and is this problem with the 2012s as well as the 2011s)? Is the problem that the stock rings couldn't handle the heat and these aftermarket rings will be fine? or should I get an after market carb and exhaust also? I would rather take precaution and be proactive about it if there might be a problem. But if I already took care of the potential problem by changing out the piston and rings then I don't have anything to worry about? Will the heat affect the aftermarket rings just as much as the stock?
Thanks

if it has the stock original sealed carb, replace ASAP.

Ok,
For the 2012 models after 09, they have still the stock (sealed) carb, but they're running a bit richer.
I removed the spark plug after 700kms and it looked nice brown (a bit on the dark side).
The bike is not bogging or anything.
Just letting you know the issue seems to be solved in the newer bikes!

This should be a huge eye opener for everyone considering about buying chinese scooters. They can't even build them from the factory right so why even waste your money on something that isn't built right the beginning.
It amazes me that people will buy something from the factory and it doesn't even have the proper parts or the proper tune. Your just going to have down time and sink more and more money into later down there road.

Actually, you'd be surprised on how well the taoTao ATM50 is tuned!
Almost every mod I do to the bike (save for the obvious like doing a BBK), results in lower performance.
I noticed, once the spark plug has been changed (or the gap of the origninal adjusted), that the scoot runs best on BP premium 93 fuel.
It goes 42,5MPH stock, and with very little wind in the back, or a car cutting the wind in front, it reaches 47,5MPH! Very good feat for a 'nearly stock' 50cc scoot!

Your just going to have down time and sink more and more money into later down there road. For the Chinese this is not about 'quality' or 'built right' as the American consumer perceives it to be. Its not fair to compare a China bike to a Japanese or Italian bike because they are not trying to be in that class of machine, they know they cannot compete with names like Honda and Vespa so how do they make money in this market? Mass production. Numbers. Make them cheap and sell them cheap, they will sell and therein lies the profits. Also, your expectations need to be properly calibrated to what you are buying. I have never expected any Chinese bike to have the level of engineering and quality of construction that a Japanese made bike would and have never been disappointed. However, I have 25 years worth of automotive repair experience so I already know to not expect that. |

Hey guys its almost time to pull out the taotao out of the garage and install a bbk for the season. I was looking at parts last night especially the nyc 72cc kit i could still use the stock head but im not sure if i would be satisfied with the power. Also i was looking at the 80cc and 85cc bbk but then i would have to change the head and calculating the cost of parts especially ncy parts im looking at $350+ dont you thing it would make sense just to buy a new 80cc engine or bigger for that price and save the headaches of assembly and disassembly I dont know. What do you guys think?

if it were me i would buy a big bore kit from ebay or scrappy...ive had alot of ncy parts and usually when it comes to the cylinder parts their alittle diff layout and better quality but performace wise the sleeve its self doesnt give more power than the other ebay kits usually its the heads that are different and thats where you can really mod for power.
if you are interested i have a used 50mm kit or 47mm kit..47mm has 120 klm on it nd 50mm has around 200klm on it. i took the off when i sold the bikes. i also have a matching head unused for the 50mm kit
