If you are thinking of buying or own a new or used 2011 TaoTao ATM50....read this post entirely!
REPLACE the carburetor with one that is NOT sealed in ANY manner as soon as possible and jet it properly!!!!!!
The sealed carbs on these are extremely lean making them run HOT which SIEZES the rings in a few thousand miles if that.
This TaoTao ATM50 was bought new about a year ago. it was found on the Craigslist Dealer section in Raleigh NC by a foreign exchange faculty member at Duke Univertisy, Durham NC to ride around the Duke Campus area. She never had any service on it besides the oil changed once. It had never even had the seat bucket off of it until i bought it from her 4/15/12.
I tested compression before i got it running and it had 140psi. After i got it running i tested it again...barely 110 or so....and was very very hard to start. I put oil down the cylinder and compression shot up to 160. Bad rings. I took her apart and this is what i found.....
It has a SEIZED lower compresion ring, scoring on the piston where it rubbed the cylinder and several cracks between the compression ring lands ...and the piston is compressed making the pin impossible to remove without great force.
it is obvious to me after having seen the insides of many many of these motors, this came from HEAT. The cooling fan system ducting is in place and the girl who rode it weighed all of 125 lbs. It has no cooling system issues and only has 1200 miles on it. This is the 3rd one I have seen with this problem. This confirms to me its from heat caused by the extremely lean sealed carbs.
REPLACE your sealed lean carb with a better unsealed unit and jet it properly to avoid ring damage on your 2011 TaoTao ATM50!! If you are looking at a used one check to see if it has the original sealed carb and do a compression test or have one done by a mechanic. Even if it does have a new carb check compression anyway....or walk away from any 2011 TaoTao ATM50.
