I have been experiencing a strange cracking noise between 3k and 4.5k rpm and I can't figure it out. Basically, I had a new intake, HD tuner, and Supertrapp slip on's put on over last winter. To date, I only have 4500 miles or so. Anyway, the noise started after this work was done.
Anyway, if I floor it a bit, like getting on the highway for example, I hear a strange cracking sound in the engine starting around 3k (throttle greater that 80%) I took it back to the dealer and explained the sound the best I could. I also said it was like a bolt rattling around in a metal dish. It's weird sound that one should hear for themselves coming right from gas tank/engine. I asked several folks at the dealer to take it for a ride. Other then revving it in neutral (which doesn't work as sound only happens under load) nothing else was done to determine the culprit. Went straight to the map. The tech who did the original work/dyno said it was "pinging" and adjusted the tuner.
So, the sound is still there. As the dealer is sort of far away, I thought I'd ask for your feedback as others may have had a similar experience. Anybody?
Trying to describe the noise on the forum makes it hard for anyone to give you the correct answer. I would say that pinging sounds like spark knock, if the noise comes from the primary area then there may be issues with the clutch or compensator. The problem with noises is that when ever you take it to the dealer the bike will not make the noise that causes you concern.
