Hi... I have a 2012 RT Se5. Lately when I ride and give it a handful of throttle at around 4000rnp I get what sounds like a screaming bearing sound. Now it doesn't do it all the time and I think its more prevalent when its cooler. If I take it out of gear and rev the engine in neutral through the rev rage its normal [as a V twin can be] which leads me to think its the transmission that's making the noise. Its definitely not drive train related and not engine related... any ideas? I didn't really notice it until I rode it without a helmet on.. sounds normal like I say until you give it some welly... if you ride it at a steady rate it doesn't make the noise...odd!
