Early on in it's life I had a few engine problems with my bike, most were probably my doing, putting the 204 cams in with an Andrews 4* advance sprocket pushed the limits of the pressed crank. HD replaced the crank with the SE welded one under warranty so I have no complaints there. I have over 60,000 miles on her now and I took her in because it was wobbly cornering (I have the ESP so I wanted them to check it before I did) They found that the rear wheel bearings were trashed and the fronts were on their way out as well. Replaced them as well as both tires because of the uneven wear it was causing. I happily paid the $50. fee. As far as the frame and tin paint I have no complaints I ride in all kinds of weather and never cover my bike when outside and it can be polished to look like the day it came out of the factory. (minus a few stone chips)
