Tao Tao ATM-50A1
Hi there,
So I recently came into possession of a scooter my friend didn't want to drag back home with him after graduation. It's a 2011 Tao Tao (I believe ATM-50A1 but I'm not sure, there's no real identification I can find.) Anyways I really want to try my hand at getting the most performance I can out of it without doing a big bore kit as I've read those have a high chance of causing damage to the engine. I've found some information here and there but not really a concise guide of everything that should be done. I don't have any experience with scooters and honestly don't even know how their engines work as I'm used to only working with cars and even then I haven't messed around in their engines that much either. Basically I need to learn how a scooter's engine works and also what can be done to maximize it's performance without major changes to the engine itself. Thanks for your time! |

Could you elaborate a bit more? I don't know what you're trying to say about the big bore kits you listed. I also don't know why you listed those in that order either, is #1 the best and #4 the worst?

Yes, I think the order is from best to worst. I'd focus on #2.
Open the link in Google Chrome, and allow it to translate. You'll be pleasantly shocked by the prices. I wouldn't hesitate to poke out a 50 to 70 with a big bore kit. I haven't actually tried it yet. Read about my adventures with a 50 here: http://www.chinariders.net/showthread.php?t=9421

Go to Youtube, and search for setting valves on a 50cc scooter. While you're at it, search for scooter CVT and variator, so you can see how they work.

Buy from reputable seller that recommend in scooter forums since most don't show marks clearly on their picture ...
Rings also cames in different grade: regular [as stock]/ CID http://www.dongya.cn/en/intro.asp?aic=9 [~1.5x the cost of regular] | PVD (Physical Vapor Deposition) [~2x the cost of CID]

Oh okay, so I guess the GY80 sounds good, now where do I get the rings? I'd rather spend a bit more for higher quality if it'll reduce the risk of damage.

Fantastic, can you confirm which options I want to select when purchasing for each of the items?
For the big bore kit should I get the "80 sets of cylinder combination" or "80 modified 100 sets of cylinder"? For the rings should I get the "GY6-60 Φ44"or a different one? Both of those I used the English translation function of google so it's almost definitely not accurate. |

That 100 means Honda "GCC" family (SCR100...) 50.0*52.0 ie. 81cc in GY6 (Stroke: 41.4) . Better ring is difficult to get in China.
72cc Φ47 1.0*1.0*2.0 Tons horizontal (pit bike/ cub...) also this size... Φ44 http://www.dongya.cn/prodlist.asp?page=1&tp=4&keywords= Generic GY60 is 1.0*1.0*2.0 BUT that shop IS using CB125T/CM125 (ie. those 125 twins): 1.0*1.0*2.5 instead (it MAY work...)
