After getting no where with the dealer with my engine pinging while riding in the mountains in eastern Arizona. I called HD Customer Service. It turn out that HD has a new map for the ECM for high temperature and high temperature riding I had the ECM reflashed and the bike runs like a champ now. If you have this problem, talk to your dealer about Calibration number 41000205. that is the newnumber for ECM 34245-11. This was for a 2011 Untra Classic, yours may be different
