Checking noise at 70mph
Weird question, I know, but I've got a 2004 Softail Heritage and ever since I've owned it its made a noise under power. I notice it when I'm hard on the throttle at the top of a gear or if I'm on the highway doing 65/70 and throttle up a hill. Its an intermittent chk-chk sound and I have never been able to figure out what it is. Sounds like it might be coming from the crank/primary, but I've never been able to stick my head down there to figure it out. The bike runs fine, has 45,000 miles on it, I bought the bike a couple years ago with 40,000 on it. Any thoughts or ideas, let me know.
Thanks!
Thanks!

You might want to put it on a dyno so you can better listen to the sound & where it's actually coming from. At least this way you won't have the wind noise or the distraction of riding safely. It will also allow you to move about the bike to hopefully isolate it's location.

Last summer I started hearing weird noises just as I hit the interstate. Sounded like something was going south in the motor, but I could only hear it at higher speed - and when I happened to stretch out on the highway pegs. As the above poster, it was the boards. I tightened the bolts, but it's actually the rubber pad slapping up and down in the pan. Sounds just metallic enough to be disconcerting. I don't see highway bars/pegs on your sig pic tho, so - - ?
I have an 07 and the same problem. It's not the floorboards or anything else rattling, it is a sound in the engine. Running along fine at 60 and then open it up to pass a car while in 6th and it clicks. It isn't lugging, just clicking. It does it at higher speeds too. When you crack the throttle wide open in 6th, it clicks in the engine somewhere.
