I've had my ace for two months and have had some issues with it already and it started at 80 miles. The first thing was the service engine soon light came on it was the speed sensor. I read online how to reset that and it fixed that. Now at 140 miles whenever I let off the gas to slow down it has a horrible squeal coming from the belt region. My dealer is little to no help being it's the only one they've sold. They just tell me to ride it until something gets worse. It's really starting to worry me all the issues that are rising
