[QUOTE="Harald, post: 1219651, member: 8054"] Another source of ticking sounds, especially after a cold engine start, is the fuel injectors. Coming from carbureted bikes, I was initially concerned with the ticking that was louder when the engine was cold (and therefore running richer = longer duration injector opening time). With almost 100,000 miles on my 07 now, I've checked the valves 3 times and the have all been in tolerance each time so ticking wasn't related to valve clearances. After reading about CCT failures, I did change out to the new model CCT at some point in there even though I didn't have the rattling sound from the right side of the engine. Bike is still running just fine. [/QUOTE]
