I purchased I scooter from Sunny Sports, since the scooter arrived, the only things i have are problems, fist of all they don't explain what kind of oil the scooter has, so after three weeks driving in the scooter it started to have problems, i had to call my brother in law to take it at the mechanist he said that the engine was partially damages because does not have sufficience oil. he repaired it also has a weird sound when you start it, to make the story short, I got the scooter on November 2009, and three times I"d have to called my friend to take me in the middle of the street because the scooter stucks all the time, the first time three weeks after I bought it and from that, several times, I do not want to use it since it always has problem on the way.
