I went with the extended warranty with my 2003 Electra Glide Classic. Don’t know why, didn’t think it would ever be used. Engine, exhaust, etc is bone stock, nothing but AMSOIL products used and the bike for the most part is babied. Then at 30,500 miles a camshaft failed (dealer said the cam wasn't hardend at the factory). The cost of the repair would have been more than the cost of the warranty.
Glad the warranty was there, really(edit) that the bike failed at 30,500 miles.
