Hey Group. I ran my bike hard while auto tuning my FP3. I wasn't doing anything abnormal or dangerous, but holding it at the rev limiter, accelerating and decelerating etc. Within a day or 2 I noticed a "thunking" sound at idle from the primary. It continues whether I engage the clutch or whether cold/warm. So it's not the clutch rollover noise some have complained about. Otherwise the bike seems to run fine. At idle t's loud enough I can hear it over my radio and through a helmet.

Took it to Harley and they of course said it's "normal". Although they also said, "we're getting a lot of these lately". Go figure. They ignored the fact that it hasn't done this until last weekend. They claim it's the compensator sprocket and it's known to do make noise. Nothing to worry about.

Wondering if anyone has seen this and/or has any advice? Thanks for the help.
 
The one on my bike is pretty loud too, I haven't taken it in due to everyone else saying the dealership tells them it's normal.

Appreciate the feedback. I've had several Harley's and wouldn't have asked them either, but it was immediately a noticeable change. I guess I'll have to wait it out. At least it's under warranty.
 
I like that compensaver hulkss and would love to try one. Only problem is, I run a Baker Attitude Tensioner and I'm not sure if it will work with it. Any other alternatives? My compensator appears to have taken a dump on me. It sounds like marbles jumping around inside of the primary and I gotta get this taken care of ASAP. Thanks
 
Will a 2011 Street Glide have this issue too?

Thanks to hulkss for the 411!

Do you know if there were changes to the 2014 Primary that have resulted in this issue? I noted the product will retro fit back to 2007. Just wondering if it is a non-issue on the Twin Cam Primary's prior to 2014.

Thanks again!

Willie
