I know there have been many threads regarding various noises and whether they are normal or not, with lots of differing opinions. I picked up my 2012 RK with 300 miles on it, I am at about 3000 now and it had the first service at the dealer. I noticed today after an hour ride at idle I hear a chattering noise, goes away as soon as I touch throttle. Also doesn't do it when bike is cold. Anything I should be checking for?

 

Sounds like a ticking sewing machine? = normal.

 

I don't think so, I've read about the ticking sound and yes I have that too, this is more of a chattering sound, only at idle and when hot.

 

Ride it to the dealer and ask them about, they should be able to help you.

 

Could be the rockers loosening up a bit.

 

In neutral, clutch pulled in, clutch handle out? Right side , primary side, fluid levels checked? A little help here, thank you.

 

Does it have ABS on the front brakes?

 

In neutral, clutch out (hands off bike), fluids good, only when hot and idling, as soon as I touch throttle in neutral it is gone.

 

Yes it has abs, I'm assuming front and back.

 

Just a guess primary chain.
