Mine does it, I actually complained about it going down the Interstate and the tech found it at idle. He said the only thing you can do is rebuild the transmission and he said it won't hurt anything, ride it until it breaks. That was 17,000 miles ago.

 

I wonder if the primary chain is a bit slack and as the slack is taken up and then released it slams the transmission from drive to coast and back again. What you hear is coming from the transmission but caused by the primary-just a wild guess.

 

I understand a "neutral rattle" but when you are riding , this so called rattle shouldn't be noticible.. It goes away , mostly, after the drive train is hot.. It does it under load and appears not to be lifters since I can sit in the driveway and rev the motor and there is no valve noise.. It is a KNOCK and is noticible and loud at 2500 up to 3000 rpm.. I guess two more times into the dealer and the lemon law kicks in !!!!!!

 

Take it to another dealer.

 

Yep. Trying different fluids changes the noise somewhat, but it's normal. It's a v-twin that isn't smooth, you can't expect it to sound like a Honda.

 

Lemon Law requires that there is actually something broke that they cant fix.

Also....when you dredge up an old thread your issues get confused with the original post

 

That was my complaint. It still does it good and hot. If you dig around there are a lot of guys that complain about this. The only thing I can tell you is it has not broken in a lot of miles for me. Under load load it kind of sounds like a wood mallet is hitting the clutch cover. I now just consider it the nature of the beast. These Harleys make a lot of strange noises. Most of them mean exactly nothing.

 

Here's what the Harley rep said who took it for a ride.. Harleys are not custom bikes but production bikes and the tolerances aren't like a custom ! Ride it !!... Now that is what the factory rep is told to tell us.. Sounds like crap to me !!!!!

 

Been thru a lemon law suit with Ford and beat them on dash rattles.. this is no difference.. Just gotta start the ball rolling to get their attention and find out what the problem is instead of everyone complaining...

 

I have had the same problem, I had a second opinion and I was told to put a heavier oil in the transmission, done that today, ran bike till it got hot, seems to quiet n it up some, but sometimes there is a knocking sound when you throttle up or down, that comes from the design of the back wheel. There is a rubber gear in the back rim. Still don't like any noise coming from anywheres except my pipes. Was told it has become a normal screw up
