Reports submitted to NHTSA, shown in the owner's own words
I brought my motorcycle into a Harley Davidson dealer for a Virginia State Safety Inspection. The inspector noticed a crack in the powder-coat of paint covering a welded section of the frame. Further investigation revealed the crack in the paint followed the edge of the weld and the weld is lifted off of the frame. Harley Davidson Corporate was notified and I was told the motorcycle is out of warranty and damage was probably cause by miss use or accident. They told me it was an insurance issue. I called Geico and reported the claim. They investigated and denied the claim saying it was not related to an accident. I called Harley Davidson Corporate and told them the results of the insurance investigation but it did not change their mind. The weld is the strongest point of any manufactured steel component. If the weld is failing it can only be from a defective welding job. The motorcycle is still sitting at the dealership in Virginia.

A TAPPET CATASTROPHICALLY FAILED, CAUSING COMPLETE ENGINE FAILURE. A COMPLETE ENGINE FAILURE ON A MOTORCYCLE IS A VERY DANGEROUS EVENT. MANY HARLEY-DAVIDSON CVO 110 ENGINES HAVE EXPERIENCED THE EXACT SAME FAILURE. THE VEHICLE WAS IN MOTION ON A HIGHWAY WHEN THE ENGINE FAILED. HARLEY-DAVIDSON IS AWARE OF THE PROBLEM BUT REFUSES TO ACKNOWLEDGE THE DEFECT, WHICH IS THE RESULT OF BAD METALLURGY AND POOR DESIGN OF THE TAPPET TO CAM INTERFACE IN THE 110 TWIN-CAM ENGINES. THESE BIKES SHOULD BE RECALLED FOR REPLACEMENT OF THE CAMS AND TAPPETS. AGAIN, THE DANGER OF A CATASTROPHIC ENGINE FAILURE IN A MOTORCYCLE IS EXTREME. A PHOTO OF THE TAPPET FAILURE IS ATTACHED.
